Flex Belt Reviews: Scam or Legit?

Rated 3.6 out of 5


As a certified EMS instructor, I always receive inquiries from friends interested in using EMS stimulators to build muscles from the comfort of their home.

This time, the abs stimulator in question is called the Flex Belt. It claims to be an FDA-cleared device that can help strengthen and define your core with just 30 minutes a day.

Does it sound too good to be true? Is it a scam? Curious, I decided to put it to the test on my own abs…

In this comprehensive review, we’ll delve into the science behind its effectiveness, its features, and how it compares to potential alternatives.

What is the Flex Belt?

The Flex Belt is an electric muscle stimulator (EMS) device that claims to strengthen and tone your abs muscles using medical grade abdominal toning technology. 

Believe it or not, the company claims that wrapping the Flex Belt around your midsection can simultaneously stimulate all your major stomach muscles, including your upper abs, lower abs, and even your obliques.

On their sales page, here are their official words on the Flex Belt…

Discreet and rechargeable, THE FLEX BELT delivers results in just 8 weeks using clinically proven EMS technology which exercises all of the abdominal muscles simultaneously.

Is The Flex Belt FDA Approved?

The Flex Belt claims to be FDA approved, but that’s not accurate. According to the FDA, only Slendertone Flex, marketed by BMR NeuroTech, Inc., has been cleared for toning, strengthening, and firming abdominal muscles.

How Does Flex Belt Work?

The Flex Belt operates like other abs stimulators by using electrical impulses to trigger muscle contractions. The device has three medical-grade gel pads inside. When you turn it on, it uses EMS technology to send electrical impulses to your abdominal muscles through these gel pads. In one word, it imitates how your nerves activate muscles. 

But the contractions aren’t as intense or precise as when you actively flex your muscles.

When it comes to boosting muscle strength, posture, or trimming your waistline, there’s not a lot of solid proof that abs stimulators like this one really do the trick. Studies checking these devices have found only minor changes, not enough to make a significant visual impact.

For instance, a study in 2005 followed 24 adults who didn’t exercise but used ab stimulators five days a week for 8 weeks. They compared them with 16 adults who didn’t use these devices or do ab exercises during that time.

The folks using the stimulators showed a 58% increase in ab strength, measured with a fancy device called an isokinetic dynamometer. They also had double the abdominal endurance compared to those who didn’t use the stimulators, while the control group had a 28% increase.

So, it hints that ab stimulators might help with strength and posture and might slightly shrink the waistline. But remember, this study was pretty small, and it hasn’t been repeated by other researchers.

In short, we can’t say for sure how effective ab stimulators like the Flex Belt really are based on solid scientific evidence.

Can Flex Belt Help You Burn Fat?

Nope, the Flex Belt and similar ab stimulators can’t burn fat on their own. Losing fat requires creating a calorie deficit, where you burn more calories than you consume through exercise and daily activities. Even if these devices make your muscles a bit stronger, you won’t see a change in how you look unless you’re also shedding fat.

In fact, the official website of the Flex Belt makes it clear that it’s not designed for weight loss or reducing fat.

So, if your goal is to slim down, you’ll need to look beyond ab stimulators and focus on a combination of healthy eating and regular exercise.

What’s Included in the Package?

The Flex Belt package includes all the necessary accessories to get started right away.

Alongside the belt and controller unit, you’ll find an extender, mains charger, a set of medical-grade gel pads, a carrying case, and comprehensive instruction manuals.

Included in the Package

Intensity Levels

The Flex Belt has 150 intensity levels, making it easy to customize the experience. You can adjust the strength of the electronic pulses using the intensity controller.

It can go up to a maximum power output of 70mA, which is typical for these muscle stimulators.

But I strongly advice you to start from the lowest setting to avoid hurting your skin. 


The Flex Belt provides 10 training programs, labeled P1 to P10. The idea is to begin with P1 as a beginner and gradually advance to more challenging workouts and abdominal exercises.

P9 and P10 claim to be special bonus programs that offer a different experience compared to the others. However, I couldn’t discern a major difference when testing them.

The belt automatically switches to the next program after a set number of sessions to introduce Muscle Confusion.

Here is an overview of each program:

Flex Belt provides 10 training program


The regular belt fits waist sizes between 24″ and 47″, and it includes a belt extender for waist sizes up to 52″.

The package also includes a convenient carry pouch to keep the belt and its accessories organized.

This is useful for on-the-go use or to prevent losing anything. The pouch measures 13″ x 7.5″.

Battery & Charging

The Flex Belt operates on a rechargeable battery, and a flashing battery icon on the screen signals when it’s running low. The package includes a wall charger that easily plugs into a power outlet.

According to the manual, it’s recommended to charge the battery for 5 hours before your first use.

In my experience, I found that recharging the ab belt is needed after 3 to 4 sessions. Keep in mind, this can vary based on the intensity levels and programs you use.

How to Use the Flex Belt

Using the Flex Belt is a easy, even for those new to electronic muscle stimulation. Here’s a simple  guide to get you started:

  1. Charge the Device: The battery needs to be charged for at least 5 hours the first time you use it.
  2. Prepare the Gel Pads: Make sure the gel pads are properly attached to the inside of the Flex Belt. These pads are crucial for transmitting the electrical impulses to your muscles.

  3. Put on the Belt: Wrap the Flex Belt around your waist, positioning the gel pads over your abdominal muscles. Adjust the fit to ensure it sits comfortably.

  4. Connect the Controller: Attach the controller unit to the belt. This is the device responsible for generating the electrical impulses.

  5. Choose Your Program: The Flex Belt offers various toning programs. Select the one that suits your fitness level and goals. You can also choose the intensity level based on your preference.

  6. Begin the Session: Once you’ve chosen the program and intensity, press the start button on the controller. 

  7. Sit Back and Relax: As the Flex Belt does its work, you can sit back and relax. Watch TV, read a book, or catch up on emails.

  8. Finish and Remove: Once the session is complete, press the stop button on the controller. Gently remove the belt and store it for your next session.

Did I Get Any Results After Using the Flex Belt?

Lately, I’ve noticed a bit of weight gain due to my hectic laptop lifestyle, and my abs aren’t as toned as they used to be. I figured, why not give the Flex Belt a shot? A friend tried it for a week but ditched it due to skin sensitivity, so he handed it over to me as a freebie.

I’ve used it for 2 weeks, following the company’s recommended 30 minutes a day routine.

The belt feels remarkably thin; I could barely sense anything inside, just three small nodes no larger than a nickel. To add to the inconvenience, it’s the remote control that needs charging, not the belt itself, and the remote seems needlessly complex.

Adding to my disappointment, the pulse strength is weak, even at its highest level, and it doesn’t do much for working those ab muscles.

I cranked up the intensity to the mid-90s settings, but only felt contractions (weak) in my middle stomach, nothing on the lower or upper stomach as their manual claims. However, it almost hurt my skin when the setting is too high.

So, after using it for 2 weeks, I didn’t notice any change in my midsection measurement.

I know the manual suggested using it for at least 8 weeks, but I don’t think it’s going to work if my muscles aren’t contracting much.

Praise for Flex Belt

  • The Flex Belt provides a range of programs that gradually intensify.
  • It comes with a rechargeable battery. 
  • It boasts swift delivery, allowing you to receive it within a few days.

Criticism of Flex Belt

  • You’ll need to purchase the gel pads separately.
  • Unfortunately, they failed to honor their 2-year money-back warranty.
  • Even at the highest setting, it only causes weak muscle contractions at the midsection.
  • It falsely claims to stimulate all your major stomach muscles.
  • It’s not FDA-approved, though it claims to be.
  • The claim of 100% of users experiencing toned and firm abs is blatantly false. Numerous complaints on Amazon suggest otherwise.
  • The promise of visible results within 8 weeks is exaggerated.
  • I suspect the testimonials on their official website are fake. 

Are There Any Side Effects Using the Flex Belt?

There are risks associated with using any EMS product, and the Flex Belt is no exception.

For instance, ab stimulators like the Flex Belt may interfere with other electronic devices, including pacemakers.

However, if you don’t have a medical condition, there’s very little to worry about. That said, refrain from using this equipment if:

  • You have a cardiac pacemaker, defibrillator, or heart problems.
  • You are pregnant or recently had a baby.
  • You suffer from cancer.

The instruction manual has a detailed list of warnings. It’s advisable to read them before using the device.

There’s also a psychological aspect to consider – relying solely on devices like the Flex Belt might give you a false sense of exercise or healthfulness, potentially steering you away from more beneficial physical activities and lifestyle changes.

Is The Flex Belt Safe To Use?

The Flex Belt is an unregulated ab stimulator, which could pose some risks. Its claim to be FDA-cleared is potentially misleading. Only FDA-approved devices have been proven to be free of harm to users.

Does It Hurt Or Make You Sore?

At the highest setting, it might cause some skin discomfort, but it’s meant to provide a shock within safe limits.

The company mentioned you might feel muscle soreness the next day due to muscle contractions. However, all I feel is skin pain when using it, and just a tiny bit of soreness the following day.

How Much Does The Flex Belt Cost?

The Flex Belt comes with a price tag of $199.99. 

It’s far more expensive than similar abs stimulators that can produce the same results. 

So, I don’t think it’s worth more than $100…

Refund Policy

The Flex Belt comes with a 2-year warranty, ensuring coverage for manufacturing defects under proper product usage, as detailed in the manual.

Unfortunately, many customers have expressed frustrations regarding difficulties in obtaining refunds after several months of using the product.

Is Flex Belt a Scam?

Let’s be clear: I wouldn’t label the Flex Belt as a scam. However, it falls short of delivering on its promises and relies heavily on misleading marketing tactics – a common trend seen on Amazon product pages.

Take, for instance, the bold claim of 100% of users experiencing firmer tones. A quick look at Amazon reviews tells a different story, with numerous customers expressing dissatisfaction and lack of results.

Adding to the skepticism, the assertion of FDA approval is outright false.

Even at its highest setting, the Flex Belt only provides very weak muscle contractions, which are not enough for effective ab toning. It seems intentional, likely to prevent any discomfort to users.

In the end, while not a scam, the Flex Belt falls flat in delivering what it boldly claims. Buyer beware.

Is There A Better Alternative?

The Vital Flex Core can be a great alternative to the Flex Belt. It’s cheaper and can give you similar results.

What’s great about it is its quality and versatility. It has 10 intensity levels and 6 preset programs, which can help with muscle toning.

Remember, though, it’s not a magic solution for toned abs. You still need a healthy diet and regular exercise. But if you want to make the most of your efforts, it’s worth considering.

I wanted to share my experience with the Flex Belt a product that has played a significant role in my weight loss journey. I initially started using the belt when I was actively pursuing my desired weight through a combination of dieting and regular exercise.The belt was a fantastic addition to my routine, helping me achieve a more toned and shaped abdomen. However, life took an unexpected turn last year when I was involved in an accident resulting in a back fracture. The pain was so intense that I had to halt my exercise routine and even struggled with basic activities like cooking. This unfortunate situation led to weight gain, and I found myself with an extra 60 lbs.Determined to get back on track, I remembered the positive impact the Flex Belt had on my physique. After a diligent search, I located the belt and have been using it for the past month. The results have been promising – my once bloated abdomen is taking on a more defined shape, and I’ve been diligently counting calories to aid my weight loss efforts.It’s important to note that the Flex Belt isn’t a magic solution on its own. Combining its use with a healthy diet and calorie counting has proven to be the key to success. I wear the belt every day, pushing it to the limits until the battery runs out. In my experience, consistency is crucial; wearing it twice a day, if possible, enhances the results.In conclusion, if you’re embarking on a weight loss journey, incorporating the Flex Belt into your routine can yield great results. However, it’s not a standalone solution – maintaining a healthy diet and consistent use of the belt are essential. I can confidently say that the Flex Belt has been a lifesaver in helping me reclaim control over my body, even in challenging times.

I am soooooo happy with thr new design and model. I had the original Flex Belt, the one were you had to change the pads and this is a wonderful improvement!!! No pads and it only uses water is amazing. The other improvement is the different levels and intensity. Normal ab belts don’t have a high intensity level due to the complexity of how it was made, but this belts construction allows it to have high intensity levels. Such an improvement!!!! The belt is smaller so it targets specific areas that I want to work on. Other belts that are larger doesn’t allow this and it can hurt over time. This is a must have if you are looking to increase your mid section goals!!!

I’ve used 3 other belts including the Flex Belt X-70 this unit is based off of and this is by far the best performer behind the discontinued flex belt. This thing can and will hurt you if you’re not careful. It’s one and only downfall is the lack of gel pads, gel pads would have made this a 10/10 product for safety reasons. I use this belt on it’s maximum level and have painfully bruised my skin, using water as a conductor is simply not as reliable or safe as a gel pad and should have not been used for a product that is as powerful as this. I’d personally stick to a Flex Belt if you can cough up the price for one elsewhere for that reason alone, especially if you’re someone who wishes to push this belt to its limit. Better safe than sorry, unless you want bruising.

This is great! The belt is very comfortable and the pad area inside has four places that become active. This comes with an extender, a spray bottle for assisting in damping the pads, cords, the storage pouch, belt and a very nice controller. The little spray bottle, as simple as this seems, is absolutely brilliant. I struggle with getting the pads adequately damp on my other belt. I didn’t even think about spray. The belt has a storage area sleeve to place the controller in the front. No more putting the controller in my pocket. The controller is easy to use with nice large buttons to see easily. The readout is digital and the controller charges quickly. This is a superior belt for comfort and overall use, and quality and design. 5 stars for me!

I can feel my muscles contract when I use this belt. After using it, I can feel soreness in my abdominals , so it must be working. The process is not the most pleasant, however. It feels like hundreds of little needles pinching my skin in the abdominal area. It took me some time to adjust to it, and every time I dread it slightly before I press the “on” button. But since it exercises my muscles, I stick with it :). It also beats back-pain from overdoing sit-ups.

I wasn’t sure if I wanted to get this because it might just be the same as every other belt out there, but this one works wonders for my chronic lower back pain. I had to use this backwards hoping that it will offer some relief for my back. It reminds of my tens unit, without having to deal with those sticky patches. The initial shock wave was a little too intense so I had to keep adjusting the setting to get to a more comfortable feel. And it’s working wonders so far!

I really love all of the different things you can do with this belt, from ab work to using as a TENS machine on my back. The 4 pads, along with the included water bottle, make it simple to get the pads wet and put it in place so that you don’t feel the sting associated with dry pads pricking your skin. However, I have a 33″ waist and this barely connects to the velcro at that length. This was truly intended for people with a waist over 35″ or more. I will probably get an additional piece of velcro and attach it further out on the belt so I can actually tighten it around my waist the way it should be attached. Otherwise, an excellent product.

I think the research is still out on ab toning belts but I thought I’d give the Pro Fitness Workout belt a try. I didn’t really know what to expect but after charging up the controller and strapping on the belt and turning up the intensity as documented in manual I was surprised that I felt something like a series of tiny punches delivered to my abdomen. After a few punches I turned down the intensity and the stimulation felt rather pleasant.I intensity of the stimulation can be set individually for each side of the abdomen. There’s also a program setting that adjusts both sides of the abdomen simultaneously. There are 10 modes and apparently the deliver a variety of muscle stimulation. I cycled through these modes in an attempt to determine how each differed from the other but each time I cycled to the next mode the intensity level reset so I was unable to make an intelligent comparison.The online description states there “10 workout programs, 150 intensity, from warm-up to high-intensity exercise and finally to relaxation” but the included manual is silent what each workout program delivers. The intensity levels are easier to judge because you feel the comfort level but still the question remains, at what intensity do you receive the most benefit?The lack of any kind description on what all the levels and intensities is a major flaw with this tool. I searched online but the problem was the same, there’s scant information of how to optimally use these belts. The description for this particular belt states that you will see results if you use the belt 5 days a week for 3 months.Bottom line, the belt delivers various intensities of stimulation in various modes but the effectiveness of all that has yet to be seen. I better manual with some explanation of the meaning of all these settings would improve the effectiveness of this product.

I was looking for something to use on my commute to help. I wanted something where I didn’t have to replace the gel pads later and was strong enough to feel the tension. Tried one from a different company first, but felt the power was too weak. As the saying goes “You get what you pay for.” I chose not to go the 39.99 route. So far is seems to do the job. I can feel the impulses (60 range and up for the serious contenders).Tip: spray a lot of water on the pads and your stomach for best results.

This is the first abs belt I have used for everyday use and it has been going good. It was a bit confusing for a day or two on how to use it but I got used to the settings and got used to it. I researched other belts similar to this and found this has more settings that would help. The belt had different power levels that you can gradually increase or decrease which helped a lot. It took some time to adjust to your abdominal area to get the best feel of the pads. I use it occasionally every week and do feel a difference in my body.I would recommend it to others but don’t use it as a primary workout.

This is the third type of EMS belt I buy, and it is the only one that really gives me results and it’s strong enough for me to back off the intensity. So far I have been able to increase the intensity to 85 for the last 10 minutes of the #8 program 40 minute session. It is a clone of the original Flex Belt that is off the market at this time.When I started using it I was fitting my 36″ pants snuggly, now after a few weeks I am loosely fitting back in my 34’s, but the big change started to happen once I increased the intensity past 50. You really need to challenge yourself if you want to get results, just like working out in the gym.If you feel any tingling while using this, it is because your skin is dry. Getting wet with water, or using any of those fancy ultrasound gels won’t help, I tried it all. I came upon a review of the old Flex Belt where a user recommended hydrating the skin with lotion after a shower daily, and if possible a few minutes before using the belt, then spritzing the pads and your abs before putting it on. That did it for me, I used to get a random zap once I got close to 50, now all I feel is the muscles tensing all the way up to 85, which so far is my limit.Hope that helps.

I used the belt for 8 sessions, half hour each, at a setting of 80-90, and the pads have already worn out. I put the belt on for my 9th session only to be painfully zapped. I am considering returning just based on that. Who wants to spend $$$ replacing pads that often? They should have lasted much longer for this to be anywhere near a feasible alternative for people with medical conditions who have challenges with strength training.

Flex Belt Abdominal Muscle Toner , Black, 24"-47". This is a great exercise belt!

Rated 5.0 out of 5
October 17, 2023

I purchase a Flex Belt Abdominal Muscle Toner , Black, 24″-47″ because the reviews were good, plus it was a more expensive product than most of the others on Amazon, and I wanted to get a good one. This is a good one. I have been using 2 of these myself for the past couple of weeks, plus I got one for my wife. They fit well. I need the extension that comes with the product, which works well, too.What I didn’t want was something that shocks you, and something that doesn’t get my abdominal muscles flexing. I started out at 50 and now am up to 80, and I get some really good contractions. I position one belt just above my naval, than the other just below that. Love it!Next, I position one of the belts on my lower back. After just 2 weeks of this routine I seem to be hitting the tennis ball harder (important for someone over 65), and am able to give my son a run for his money. I hate it when he beats me all the time! Of course, I am using another muscle building program for arms and shoulders, but this fills in what I need in the abdomen. A great product!Concerning the pads, some have complained that they don’t stick well or last long. I use a wash cloth each time before exercising, and using the machine for abs and lower back each day, yet after 2 weeks the pads act as if they are new. They make a super connection and work well.

I love that I don’t have to replace gel pads with this ab belt; like I did with a previous one. I enjoy the different modes and intensity levels offered! Battery life is great between charges! Very easy to use, and works great! A couple of things I wish were options; 1. The intensity could be adjusted for both sides simultaneously. 2. When you pause it, you are allowed to lower the intensity level, so it doesn’t immediately give you full level intensity when you resume your session.

I actually thought this worked pretty well. I wore it while doing the stair master at the gym. I noticed an improvement in abdominal tone. I decided to replace the gel pads. I originally got generics and they shocked me. So I tried the brand name replacement pads and it still shocked me. I believe it’s due to some stretching or warping of the fabric. (From sweating and a snug fit) I reported this to customer service and they didn’t want to replace the device. Told me that I should try purchasing new replacement pads because somehow the generic pads I used messed up the name brand pads. They told me if that didn’t work I could call and file a complaint because it’s a medical device. Basically the agent didn’t care and didn’t want to offer a replace me a replacement. So now after looking at it for months I’m just going to toss it. Very disappointed because I thought it was effective to start

I had higher expectations for this product.As mentioned by other reviewers, the size is really not as large as the listing would lead you to believe and the instructions are not very helpful.I didn’t find it easy to put on, but I suppose with some kind of practice I’d find a technique.So… it does work. But the whole thing felt a little “chinsey” to me. I think at the price point they are asking it should be a more complete and better product. I have no doubt that if I stuck with the use of it, it would burn calories and make my muscles tone up, but for now, I’ll stick to working out in the old-fashioned way.

This is my first workout belt and I’m enjoying it. I did need to use the extender, and I’m glad some other reviewer said that this can be used on the legs too as I’ve been wondering about that but haven’t tried it yet.It charges easily with the controller being able to plug into the charge cord to charge, or to the workout belt when fully charged and you want to walk around. I turn it on and once I adjust the controls, I put the controller in my pocket and go on with whatever else I want to do (like right now I’m using the belt while I’m sitting here writing this review.)There are 10 different program levels (or I think of them as workouts.) Those change up how the electrodes (?) work and go off… if they go side to side, pulse, on for a while and pause for a while, and combinations of those, etc. There are a couple I don’t like and probably won’t ever use, but I like the ability to mix it up and there are 6 or 7 programs I like to do and change up each time I do it.After you set your program, you can set the intensity from 1-70. I like that you can set the intensity differently on one side than the other, as sometimes I’m sore and I want to go a little easier on that side. I would definitely start slow but the first 10 are definitely very easy. I start feeling like it might make a difference once I’m in the 20s, and I don’t think I’ve even had the guts to try anything over 40 yet. In the 30s you can see my whole torso twitch a bit.DEFINITELY spray the pads before you use the belt. It basically feels like you are being electrically shocked otherwise… well, I guess that’s basically what happens and how it feels no matter what, but with the pads wet it doesn’t hurt other than muscles getting the workout. They give you a small spray bottle that you can fill with water. Then just spray a few pumps worth on each pad and put it on and go.The programs seem to all be between 20-30 minutes, though there may be an outlier or two. I do wish you could control the time but I haven’t figured out how other than changing the program. That said, many times I’ll do two workouts in a row, so I’m wearing the belt for about 45 minutes. I can do this even a few times a day depending on what intensity I set it at.The only critique I have is that one of the 4 pads barely works, so the one on my left side doesn’t get the workout. To counterbalance that, I turn the belt upside-down and wear it the other way so the left side can get the workout sometimes too, and the right side gets more of a break. Because I got this for free for my review through the Vine program, that doesn’t bother me as much as I’m still so excited to use this thing. That said, if I’d paid $65 for it I definitely would have at least returned it and asked for a replacement and I’d be more upset.Results? I’ve only been using this for a few weeks, and I was sick for a week in the middle of that. When I am using it, after a couple of days, my core muscles can really feel it and I do feel stronger and tighter. It may just be that they stay tenser. I do think this helps tighten things up. It’s not going to make any significant change on its own without other exercise and diet, but I can at least FEEL a difference and feel stronger, and that makes this very worth it to me and I enjoy using it regularly. It’s just SO convenient!! I also can tuck it just under my pants while I’m wearing it, though I wouldn’t wear it out in public or anything.I’m a fan!

I read some reviews that the pads need to be lubriate, so I lather lotion all over my belly before placing the belt on.No where in the instruction guide does it say to lubricate I keep trying to find it, but I trust the community and follow suit. The belt is easy to use, just put it on and plug in the two plugs. The instruction has no guide on what the settings are, you are blind here and have to just trial and error. Since I’m curvey and have a small waist but wide hip, the belt does not hug my front lower abs that well. I don’t feel the TENs on my hip. Some of the program feels like a side ache during your runs.

The unit arrived and had no instructions. Fortunately it’s fairly dummy proof but something describing the various settings would be nice. I vaguely recall reading something in the item description and/or FAQs about keeping the pad areas damp, but there was absolutely nothing about that with the unit. Ultimately this is a tens unit designed to be used on an upper leg that they provide an extra piece of velcro to use as an extension so it’s big enough to fit around the waist.

The Fitness belt was fine at first, but the electrical connection broke 3 months after purchase. I previously used the “other” name brand electrical stimulation belt with replaceable pads for ~10 years until it finally stopped working. I was disappointed to find that I could not order a replacement, so I decided to try one of the knockoffs. The permanent silicon pads were a convenient feature, but the quality of the belt wasn’t nearly as nice as my previous one. The material us bulkier and stiffer, so it wasn’t as comfortable. The controller only allowed the stimulation strength to be increased one side at a time. With my previous belt, both sides could be increased simultaneously, which saved time. But I was pretty satisfied overall – until the electrical connection stopped working. First, the belt only stimulated on one or two pads and the next time I turned it on it was dead. I am very annoyed! Yes, the belt was cheaper than my other one, but I guess you get what you pay for. Of course, the return window ended after 2 months…I am a huge fan of this style of Stimulation Belt in general. After a bad injury of my spinal cord and subsequent surgery 10 years ago, I was partially paralyzed and all of my muscles, including my core, were very weak because of nerve damage. Fortunately, I was able to walk and over ~5 years of working at it, I was able to recover to ~90% of my previous physical ability. I tried my previous belt to help strengthen my core and to limit back pain that resulted from my weak nerves and bad discs. I think using the belt was a key component of my recovery – along with a lot of walking, swimming, and PT. It also kept my waist in check, which was also nice.Overall, I am very disappointed that this relatively inexpensive belt was so poorly made and stopped working after 3 months.

Honest review here.For $67.00 I wish it was much wider… it’s only about 4 inches wide.. .but works as described.PROSThis offers 10 training programs with 150 levels of intensity … but I would argue half are not strong enough…so assume 5 training programs at the level that would be useful to you.CONSThe best is listed as fiting 24-47 inch waist. That is inaccurate. At best it fits up to 33 inches. It’s very trim and they do give you 1 extendable peice but that still only gets you to about 33 inches. SO keep that in mind.This is only about 4-5 inches tall… I wish it was 7-10… You have to use on lower abs and then switch to upper to get the whole effect. For the price I feel it should have been size bigger in all areas.Overall I wouldn’t recommend this. The size is off both in waist size and height and it’s expensive. SORRY!

I got this product to lose those 3 last inches of top belly fat. My abs are in decent shape, but the skin and the inner muscles need to meet, and after losing 20 lbs, I needed some extra help. The belt requires charging quite often, and assembly is cumbersome. You cannot wear it while exercising, maybe during a walk (where nobody can see you) or just standing in front of a TV to endure the 20 minutes, minimum required. I guess you could hide it under a baggy shirt and put the remote control in the pocket. The sensation is very unpleasant, I used it a few times really curious if it could work. I know anatomy and physiology fairly well to see that the action is too random, and the muscle crunch is less effective than good abdominal workouts you have so many on YouTube, especially the ones taught by European dancers and gymnasts. After abs warm ups I feel well, and it is worth the effort.

I never tried one of these before, so starting out I stayed on 12-15 for intensity. My second time I was curious how high it went and made to level 31 and I can really feel the intensity. I think this is a great addition to add on days you can’t work your abs. I kinda feel like My body temperature is rising.

I’m a 73-year-old woman who rides an e-bike frequently. With the strengthening of my abdominal muscles, I can handle the bumpy road with ease. Also, I notice more core body strength during my pickleball games. Highly recommend this belt.

 The Abdominal Training Belt is amazing, it does works, and the intensity of the massager is just great, you can really feel it.I like that it has a remote control so you can control the intensity and the different patterns.You can use it while you work, read a book or just while you are on your cellphone like right now I’m wearing it and I just love it.It’s rechargable and it will last a very good amount of time.Good price fir this great abs training!

Been using this for about 100 days i have moved up one level per day and this has all but eliminated my back pain and has allowed me to begin working manually on different core muscle groups. if you are patient you will see and feel this working every day. The only negative is the Velcro quality is not as good as it should be for everyday use. But I will give it an overall of 5 of 5

Helps tone, but won't target fat

Rated 4.0 out of 5
July 21, 2023

7/20/2023What this belt does do is encourage contractions of the abs and in ways I personally cannot do with crunches alone. I value this because for me this is the most neglected muscle group of a typical day. Think of all the movements you might do even as a physical worker. The abs hardly ever get worked, really. At my gym, they have a couple machines that really target the abs and obliques, but I don’t work them consistently enough to build tone. The belt provides strong, programmed stimulation for sessions long enough to be considered a workout. If you feel fatigued at the end, you did work something. Of all the as seen on tv crap out there, this device is actually doing something. If the connector fails, I will change my review, but on first impression, this really is working.One annoyance: The on/ off symbol on the charger is not a capacitive button but a logo. I pressed it so many times thinking it was a switch. 🤦🏼‍♂️Good luck!7/22/2023Update: It took a couple cycles to fully charge the battery, but it is full now. Serial number is “Z”, suggesting manufactured in 2020, so not old. But it is NiMH, meaning much better than NiCad but not as forgiving as lithium, so this behavior might be expected. Don’t leave it on the charger 24/7 hoping to get a full charge. Use it ’til almost dead, then charge again and it should charge more fully.I’ve found the device as more of a great coach than a magic pill. It flexes my abs sideways, which is an activation my brain can’t quite do. I’ve also noticed two phenomena: If I go completely limp, the surprise flex will upset the muscle more strongly than fighting it. Also, if I use my brain to help activate the muscle in the exact same manner as the device, I find that the two signals add for increased intensity without dialing it up. In fact, I find dialing it past 110 to be less constructive than the two aforementioned methods.In cooperating with the program (rather than passively tolerating it), I find myself far more engaged and entertained. I’d normally do about 5 minutes of intense crunches on a machine and get bored and move on. With the Flex Belt, I’m encouraged into a productive session because I’m literally strapped in. Pulling it off without a good workout would contribute to premature pad wear and replacement. Also, getting comfortable and dialing it up takes so much time, you might as well get on with a good workout.I’m coming from a decent place, fitness-wise, with about 20% bodyfat. I’ve been using this thing about a hour per day, really pushing myself (being careful not to tear a muscle), and feeling decently sore. I know that feeling means something good is happening, but to wait a few more days ’til the soreness goes away prior to doing more abs.So far so good!7/26/2023I’ve been using this pretty consistently for several days, now. I definitely felt a plateau after the first session. The first use was after about a month of not bothering with abs, so that explains why I felt so worked out and sore on the first use. Subsequent sessions were underwhelming by comparison. What I use this for now is sort of an intra-workout massage. By incorporating some massaging twitch, I sm able to overcome the boredom and fatigue of doing tons of crunches. I stay engaged longer, psychologically. Thus, I am finally starting to see results, but it’s mostly coming from traditional crunches.

Have tried reconnecting the inputs several times andusi g different outlet but no luck. When I Google FlexBelt.com to obtain a customer service number, I get Facebook, Amazon, Etc., Etc. but no website to contact. Need to find out how to get in touch with customer service to fix this.

Sent used, broken product

Rated 1.0 out of 5
June 25, 2023

First and foremost, I was sent a used product. The pads were already taken out and attached to the belt. The instruction manual looked like it had been thrown in the washer and dryer. The sticker tape holding the box together was absolutely repulsive. The holding bag was covered in a THICK layer of dust. The plastic wrap on the belt extender was torn wide open. The contents were just a completely mess when we opened it up, as if everything was randomly thrown into the box. This part is more a criticism about the seller, who didn’t even bother to check the returned product and immediately put it up for sale again with no care in the world.Secondly, the belt seems excessively thin. We couldn’t actually feel anything inside except for three small nodes, no larger than a nickel. Plus it wasn’t even the belt itself that we had to charge, it was the little remote control. The remote also seemed unnecessarily complicated. We were able to turn it on just fine, but nothing actually… worked.I will be returning this product as soon as humanly possible. Incredibly disappointed. Would. NOT. Recommend.

I have had this belt for about 6 weeks and it started out pretty good, but the digital device has never seated correctly and easily disconnects. Now, the entire left side is barely working. I have tried changing the pads but no luck. There is obviously an issue with the connectivity between the power unit and the left side. The center section is not as intense as it first was either. I have used this everyday to supplement strengthening my core after a car accident so the difference is very obvious to me.What’s more, the return policy is ONLY 30 DAYS so it shows this company had ZERO faith in their products.

Heart & Nerves Health Concerns

June 16, 2023

Health Concern, I purchased all 3 equipments and used each one once a week. (Arm, Abs. Gluts) developed little Heart pain on the 2nd week and continued on. I have not had any history of heart problem before or in my family history. I ended up in ER for cautions. my pulse was a bit off. When stopped using these , it went away , started using it and the pain came back. I returned all equipments today. When the pad heat up, it is uncomfortable. It only targets 1 muscle group. To feel the muscle contraction you have to set it on high and then you get nerve pluses down your thighs to the knees NOT SURE IF THESE ARE GOOD SIGNS. I RATHER NOT RRISK MY HEALTH AND MIGHT AS WELL WORK OUT.

The ORIGINAL, Best on the market!!!

Rated 5.0 out of 5
June 15, 2023

THIS REVIEW IS NOT AN ENDORSEMENT NOT DID I GET ANYTHING FREE FOR IT!!!Ok after coming across this while researching another fitness machine, and reading all of the comment reviews, I just HAVE to leave a long review.. My husband actually bought this abdominal belt I want to say over 9 years ago when it actually came out on the market. (you could ONLY purchase it through the manufacturer) so we spent well over $200 getting the belt, extra pads, and insurance) we didnt know what we were going to get or if it was going to work…we just went by what the marketing commercials and all of the reviews(which at the time were very few) when we finally received the package we were excited and flipped a coin as to whom was going to be the test subject” He won…and we read every single word from the instruction manual and began the process of charging the batteries fully, affixing the gel pads to the belt, then actually placing the gel pads(that we already put on the belt) on the right areas of my husband’s torso, then clipping the fully charged control onto the belt and he turned the unit on. YES it worked…shockingly it worked…better that we could have EVER thought or hoped!! His abs were actually constricting….not a little, were you could feel them, but A LOT, WERE YOU COULD FEEL THEM AND SEE THEM!!! then i took my turn…and the same happened….I was actually able to go higher in intensity than my husband my 1st time but we both knew that this might be because I am a mother that birthed three children, and hence my threshold of discomfort was higher than his. WE WERE sold!!! we were actually tired and sweating after the session. so we continued using the belt(still to this day) but we also invested in the arm belts and the buttocks belt (for myself) we have had these ORIGINAL belts for close to 10 yrs now and have only had to change the gel pads ONCE…as we became used to the levels we work out(both at home or the gym) go shopping, ride our bikes, or go jogging with the belt on and running)…THIS BELT IS NOT FOR PEOPLE TO JUST PUT IT ON, NOT FOLLOW A HEALTHY LIFE STYLE) and think that the belt is going to do the job for you(although it will help in toning and build some muscle) you have to do the work yourself. BELIEVE ME THEY DO HELP!!!

Great advantage not dealing with buying new pads. It does work, been using it for a couple of month and notice definition, but that is also paired with diet and regular exercise. The only negative I would say is I wish the fixed pads on the belt would saturate more as the water evaporates quickly and may require re-saturation. Overall pleased with this belt.

The fabric is comfortable, however make sure it is a good connection first because it does sting if it is not a good connection. It came with a bag and also a small spray bottle, but it did not say what it was for so I am still wondering. I don’t know if it will give results but I do feel the muscles tense a bit with its use.

This belt will definitely help your abs come through if your body fat percentage is around mine, but if it’s above 20 or so percent, you probs won’t see the results as much.

That said I use it between 85 and 100 and it gives your muscles a kick! Such a good work out. I even strap it to my chest and works great there as well. I feel like the weak reviews on here are simply from people not using it at a high enough level so of course they will get no results.

I love this EMS belt, it works very similar to flex belt that you can’t get anymore. I like this even better bc don’t need to buy those gel pads. Just spray with water on pads and you are good to go.I was mainly looking for something to help me strengthen my core so I can do more and not strain my neck so much during ab exercises. I have neck injury currently from car accident some years back and when I get fatigued during core and ab workouts I use my neck and it causes more strain and pain. This is really helping with core strength and helps me have better posture sitting at my desk working from home. I feel it working and is helping to keep my abs in. I am starting to see some differences after just a week.

It’s simple to use and the built-in electrodes conduct well. I find that it works better by placing an additional elastic belt over top of the belt for better electrode contact. It will allow you to use a higher intensity without a burning or stinging sensation from poor electrode contact. Overall I’m happy with it.

First off, it does work. I crank it up to about 125 or so. Currently pushing the max setting and feeling the burn!!!. I highly recommend carefully reading all of the instructions and reviewing the videos to ensure you are accurately using the product. Time will tell how long it stays effective. So far so good, and I am enjoying the ab workout while being able to do other things at the same time.

The Flex Belt is good quality. It is easy to use and definitely stimulates the abdominal muscles well. I include it as part of my weekly routine that also involves heavy core workouts. Overall – good quality ab belt.

It doesn’t have the power to be effective at all. I used the belt once and I had to max out the power just to get it to feel anything. I made sure the battery was fully charged before I used the belt. I even put new pads on but it still didn’t work well I’m sorry but I’m sending this back. I purchased another AB EMS Stimulator product and spent about half the money I spent on the Nbody for another brand and the new one worked fantastic.

This is my second one I had to return my first one because one of the electrical pads was not working so will see how this one does I really wish there was instructions or some kind of information to explain how this all works and for how long you are supposed to use it at a time. It does not come with any instructions at all. The belt itself has Velcro that is irritating on the skin that I wish was made better for that fact. On a better note this does help work the stomach muscles. If the company is reading this please send me some instructions on this.

I have been using off brand versions of the flex belt on and off for ten years . My biggest grievances have been pads wearing down after days of use, electric shock feelings, belts and pads that bent easily, belt and pads that didn’t conform to body while moving around and actual skin burns some of which show up as light scars on my torso. Since using this belt for almost a week, I’ve noticed that I’ve had none of the issues that I’ve had prior with others. Super comfortable, very flexible and forms to the body(even while sitting) you can just tell that these pads are made of superior quality and will perform much longer. I already feel and see a difference. I have lost two inches already but I must admit that strict Keto diet probably aided in this. I feel like this belt is a great addition to doing cardio a couple times a day and a healthy diet. My only complaint is the pads are crazy sticky and it seems because of this it’s easy to damage them while placing pads on belt. I will make sure to update my review once a month has passed. Overall very pleased . Worth the $$$

Unfortunately I was bought into the hype by some guy who goes by the moniker “Alpha M”.I’ve seen these gimmicks since the 90s, but figured after a few decades they FINALLY got it right….wrong.Still the same crap tech that generates the same electro-shock therapy which produces unwarranted results of pain and great discomfort.The gel pads wear it with great haste thus preventing the belt/remote to function at all. When you try to raise the levels it’ll start beeping with an [!] in the center, rendering the belt obsolete until you replace the pads, which is NOT a guarantee!There can be a plethora of problems that are invisible to your average consumer.Basically: Save your money and save yourself a huge headache because this insanely expensive item is not user friendly!

February 5, 2023

Ill review because I wish people would review!I just received this in the mail, I put the settings at 44/45 for 35 minutes and It feels like a you’re in labor and similar to a contraction. I do like the remote, it shows when you should feel a ”contraction” it is easily readable and useable. It will come with 1 set of the gel pads, they are super sticky and good quality. I did go and buy a few additional sets (same brand) as I think ill need to reapply new ones every few uses. I read other people used off brand gel pads and did not have good results. The gel pads are supposed to be moved differently on the belt for different waist sizes however my husband used it and never moved the pads after I wore it. I feel like for the price the company should have included more gel pads because they are pricy ( I believe $12 per pack) The belt has a pocket for the remote so you can go hands free, the remote also has a beeping timer and shuts off. The controls go easily up and down so if you shouldn’t have the instant discomfort from jumping levels fast. I did zap myself taking off the belt while it was on level 6, I was attempting to adjust the waist. If you need to adjust just make sure the belt is off or at level 0 unless you want a bolt. After the first use I do not feel any soreness unless I strongly flex my abs, then I somewhat feel some discomfort but nothing noticeable. My husband feels soreness when he bends or any movement in his ab area, he was around level 50/60 for 2 – 35 minutes secessions.I purchased this just to see if this works, my plastic surgeon uses a similar machine ( for $2000 per treatment) and he said it is based off similar technology. I do regularly workout and I do not expect some miracle machine, that only comes with hitting the gym/ diet however I’m intrigued at the concept. We shall see how this goes maybe it will help build that muscle faster.

It’s great when it works, but every few months it stops working. The screen flashes when you try to start the program and doesn’t do anything. I’ve tried cleaning the pads, but nothing works. It’s a waste of money.

Sounds dumb but just search up the original flex belt instruction video. This EMS belt is a clone of that one and the instructions pretty much overlap perfectly. The belt itself is great, gives me a good workout every time. It’s not a magic pill tho and you definitely need to change your diet and lifestyle if you want to see abs.

So I bought this in hopes to use this in place of my tens when I didn’t have my hubby available to help. I’m still trying to figure out how it works. I’ve read the manual and followed the steps, but I don’t know if it’s a defective unit or if it truly doesn’t work. It powers on, but I don’t feel a thing. I’ll keep playing around with it to see if I’m missing something and will update the review if I find it does work, but for now, I can’t give it a good review. It may just end up in the trash. I gave it two stars at least because although I can’t get the unit to work, I’ve found it holds ice packs or heat packs in place really well so it’s not a total waste, lol.

I have a bad back and I’ve needed to build up my back muscles. Boy has this helped! This pro fitness workout belt is easy to operate and works very well. I can definitely tell that my muscles are being worked! The instruction manual is informative and easy to read. Simply charge the controller for 30 minutes, then it is ready to connect to the belt for use. It includes a small spray bottle that you fill with water to spray onto the silicone pads prior to use. The controller is easy to read and use. There is a timer and you can adjust the strength. The belt is velcro and stays in place. There is also an included extender to add to the length of the belt. This works great on my back and my abdomen as well. Combine this with a healthy diet and you will see results! I recommend the Flex Belt!

I really wanted to like this because I want to lose some weight especially around my belly but I couldn’t use it because I felt sharp pain using it… It feels like my skin is getting electrocuted and the shock is painful enough for me to not want to use it. On top of that, I found a post card inside the box that may explain why so many people praised this product… very disappointed.

Strong current and versatile uses

Rated 5.0 out of 5
January 2, 2023

I ordered the Flex Belt to jump start my new year new me fitness routine. Out of the box the instructions were easy to follow and set up the workout belt. The belt was big on me as I have a 28 inch waist and I was barely able to get it attached to some velcro but in will need to make some adjustments with added velcro to get a proper fit. I sprayed the water on the electrode pads then wrapped the belt around my waist and I was good to get started. The current was stronger than I expected which was great! I wanted to feel sore after a session and I was not disappointed. Overall I think this is a good product because it is versatile and can be used on the abdomen or for back aches and it has a strong electric current.
