Vital Flex Core Reviews: Scam or Legit?

Rated 4.9 out of 5


Ever heard of an abs stimulator that promises a toned abdomen without breaking a sweat? It does sound a bit absurd, doesn’t it?

Well, that was my initial reaction too!

In this honest Vital Flex Core EMS Stimulator Review, I’ll share everything about this device, including my personal experience. I wanted to find out if it lives up to the manufacturer’s marketing claims.

Can it deliver results for people who can’t or don’t want to hit the gym? Is it suitable for those with a busy lifestyle who can’t spare much time for exercise?

I understand the struggle with staying motivated. It’s tough, especially with so many products out there making bold claims. Diet teas, detox formulas, laxatives, protein shakes – the list goes on. Finding genuine reviews can be a challenge.

It’s only natural to be skeptical and want to invest your money in something that seems legitimate. So, let’s dive into the Vital Flex Core EMS Stimulator and see if it’s worth considering.

What is Vital Flex Core?

The Vital Flex Core is an abs stimulator that sticks onto your midsection. This pad delivers controlled electrical impulses, essentially mimicking the muscle contractions you’d experience during traditional abdominal exercises like crunches and sit-ups.

According to the company, they use medical-grade simulated technology to tone, strengthen, and firm your abdomen.

Just wear the abs stimulator for a few hours a day at home or the office, and you should start seeing a noticeable difference in a few weeks.

Sounds hassle-free, right?

Vital Flex Core

How Does It Work?

The Vital Flex Core operates through electronic muscle stimulation (EMS). Inside the device, there are strategically positioned medical-grade gel pads.

When you turn it on, EMS technology sends electrical impulses through these gel pads to your abdominal region. This triggers your abdominal muscles to contract and relax, imitating the natural process during exercise.

Typically, our brain signals muscles to contract when we move, but with EMS, this contraction happens automatically without conscious effort.

Because this movement is focused on the mid-section, it’s safe to say that the effects specifically target the core muscles in that area. It aims to strengthen and tone various stomach muscles, including the upper and lower abs, obliques, and love handles.

The great part is that you get a workout for your core muscles without the need for strenuous physical activity.

Does Vital Flex Core Work?

I’m usually pretty skeptical when it comes to fitness products. The market is flooded with items that make big promises, cost a fortune, and end up falling short.

However, what caught my attention with the Vital Flex Core was its FDA approval. It’s given the green light for “toning, strengthening, and firming abdominal muscles.” To get this approval, the manufacturers had to back up their claims by presenting their research and development data for thorough evaluation by the Food and Drug Administration.

The EMS technology I mentioned earlier is widely used in the sports and fitness industry, as well as in physiotherapy, athletic sciences, rehabilitation, and recovery.

EMS allows users to focus on a specific body area, putting it under stress without affecting the rest of the body—similar to how pressure is applied to tendons and joints.

Intensity Levels

The Vital Flex Core comes with 6 modes and 9 intensity levels, making it easy for me to customize and find the perfect setting. Adjusting the strength of the electronic pulses is done with the intensity controller.

I’ve heard some folks struggle when an EMS device is either too intense (uncomfortable) or too weak (ineffective). Fortunately, that wasn’t an issue for me with the Vital Flex Core.

Wondering about its power? The maximum output is 70mA, which is pretty standard for these muscle stimulators.


The Vital Flex Core muscle stimulator provides 6 modes, designed for a progressive approach. You begin with mode 1 as a beginner and can gradually move on to more intense workout programs and abdominal exercises.

According to the manufacturer, these toning programs follow the concept of Muscle Confusion.

The idea is that by varying your ab workouts, your body won’t adapt and hit a plateau. However, there’s still ongoing debate about whether Muscle Confusion is a valid concept.

Battery & Charging

The Vital Flex Core operates on a rechargeable battery, and a flashing battery icon on the screen signals when it’s running low.

It includes a USB charger that plugs directly into a power outlet. In my experience, the ab belt typically needs recharging after 3 to 4 sessions, but this can vary based on the intensity levels and programs you use.

A full charge takes approximately 2 to 3 hours. I’ve been regularly using it for abdominal toning for 3 months without any battery issues. The convenience of recharging is a plus compared to constantly buying new batteries.

However, after a year of regular use, I noticed the battery lasting only 1 to 2 sessions before requiring a full recharge. This is normal for rechargeable batteries, which have a limited number of charge cycles before needing replacement.

Side Effects & Dangers

While any EMS product carries some health risks, the Vital Flex Core’s FDA clearance means these risks are relatively low compared to unapproved fitness devices.

If you don’t have a medical condition, there’s generally little to worry about. However, you should avoid using this equipment if:

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

The instruction manual includes a comprehensive list of warnings at the beginning. It’s strongly recommended to read these before using the device.

Is Vital Flex Core Safe To Use?

The Vital Flex Core is deemed safe as it has FDA approval, being the first device of its kind to receive the green light from the Food and Drug Administration.

To achieve FDA clearance, the device must demonstrate that it not only poses no harm to the user but also provides some tangible benefits.

Does Vital Flex Core Hurt Or Make You Sore?

Setting the intensity too high on EMS devices can be a bit shocking and even hurt. However, if you’re sensible and follow the instructions carefully, it shouldn’t be painful.

It’s normal to feel muscle soreness the day after a solid abdominal workout with the belt. This is expected because of the muscle contractions your body undergoes, similar to the soreness you might feel after doing traditional ab exercises like crunches.

Can It Cause Cancer?

Some may worry about radiation when using an electronic device close to the body for extended periods.

According to the manufacturer, the device emits extremely low levels of radiation and adheres to radiation safety standards. In comparison, a mobile phone emits 50 times more radiation.

How to Use Vital Flex Core?

I’m not the most tech-savvy person, but I found this product easy to start using.

The manufacturer has kept things simple, making the device user-friendly for a wide range of users without unnecessary complexity. Setting up the device involves three straightforward steps:

  1. Charge the device
  2. Connect the abs stimulator and controller
  3. Attach the gel pads to the stimulator

Once done, you can remove the protective covers from the gel pads, position the belt on your body as instructed, and you’re good to go.

Operating the device is a breeze with just a few buttons on the controller. The + and – buttons adjust intensity, and the others manage programs and power. The buttons are clearly labeled, so no worries about accidentally cranking up the intensity when you mean to switch it off!

Vital Flex Core Results – Before and After

In my opinion, the Vital Flex Core is effective. I’m a 6-foot man, and with regular use, I noticed significant results. So, yes, the Vital Flex Core is legit!

Here are my midsection measurements before and after using it for 3 months:

  • Before: 38.1 inches.
  • After: 36.2 inches.

That’s a 2-inch reduction in my midsection.

How Long To See Results From the Vital Flex Core?

The timeframe for seeing results with the Vital Flex Core varies based on your lifestyle. If you rely solely on the belt without incorporating exercise or a healthy diet, results may take longer.

If you’re already lean, results can be quick. Personally, I noticed a significant change in my midsection and abdominal region after just 4 weeks of use.

Who is Vital Flex Core for?

The Vital Flex Core Ab Stimulator comes with a range of benefits that make it suitable for a broad audience:

  • Fitness Enthusiasts: A great addition to workout routines or everyday body maintenance.
  • Those with Painful Joints: Suitable for people with weak joints or conditions like arthritis, offering a way to stay in shape without rigorous exercises.
  • Busy People: Perfect for people with busy schedules, whether due to work shifts or parenting, providing a convenient way to tone muscles without hitting the gym.

However, it’s essential to note that while the Vital Flex Core is effective for toning muscles, it does not claim to burn fat or lead to extreme weight loss.

It’s not an alternative to liposuction, and it acknowledges that addressing stubborn body fat around the midsection requires healthy lifestyle changes.

Pros for Vital Flex Core Ab Stimulator

  1. Convenient Usage: I work a full-time job and have a busy schedule, but with the Vital Flex Core Ab Stimulator, I only need to dedicate 30 minutes per day to tone my abs. This means I can easily fit my ab workouts into my daily routine without feeling overwhelmed by exercise commitments. For instance, I usually use it during my lunch break at work, which gives me the perfect opportunity to strengthen my core without sacrificing too much time.
  2. Multitasking Capability: As a parent, my days are packed with various tasks and responsibilities. With the Vital Flex Core Ab Stimulator, I can maximize my time by using it while I’m doing other activities around the house. For example, I often wear it while I’m cooking dinner for my family or while I’m folding laundry. This way, I can still get an effective ab workout in while taking care of my household chores or spending time with my family. It’s like getting two tasks done at once!
  3. Customizable Workouts: Everyone’s fitness levels and preferences are different, and that’s why I appreciate the customizable options of the Vital Flex Core Ab Stimulator. With its 6 modes and 9 intensity levels, I can tailor my workouts to suit my specific needs and goals. For instance, on days when I’m feeling more energetic, I can increase the intensity level for a more challenging session. Conversely, on days when I need a gentler workout, I can opt for a lower intensity level. This flexibility allows me to personalize my training sessions and ensures that I can progress at my own pace.
  4. Muscle Confusion Training: As someone who has been working on strengthening my core for a while now, I’ve noticed that my progress sometimes hits a plateau. However, with the Vital Flex Core Ab Stimulator’s muscle confusion training, I no longer have to worry about stagnating results. The device utilizes varied programs that constantly challenge my muscles in different ways, preventing them from getting accustomed to the same routine. For instance, one day I might use the pulse mode, while the next I switch to the tapping mode. This variation keeps my muscles guessing and ensures that I continue to see improvements in my core strength and appearance over time.
  5. Noticeable Results: Since incorporating the Vital Flex Core Ab Stimulator into my fitness routine, I’ve noticed significant improvements in the strength and appearance of my abs. With regular use, my abs have become noticeably stronger and tighter, which has not only enhanced my core strength but also improved the overall aesthetic of my midsection. For instance, I’ve started to see more definition and tone in my abdominal muscles, which is something I’ve been striving for. These visible results have been a great motivator for me to keep using the device consistently and continue working towards my fitness goals.
  6. User-Friendly Design: When I first started using the Vital Flex Core Ab Stimulator, I was pleasantly surprised by how easy it was to operate. The device comes with clear instructions that guide you through the setup process and explain how to use each mode and intensity level. Even as someone who isn’t particularly tech-savvy, I found the operation to be straightforward and intuitive. For example, adjusting the intensity levels is as simple as pressing a button, and the LED display clearly indicates which mode and intensity level you’re currently on. This user-friendly design makes the device accessible to a wide range of users, regardless of their technical proficiency or prior experience with similar products.

Cons of Vital Flex Core Ab Stimulator

  1. Pad Replacement: I found that the pads of the Vital Flex Core Ab Stimulator needed to be replaced regularly after about 30 sessions. This meant that I had to factor in the cost of purchasing replacement pads into my long-term maintenance expenses. For example, after using the stimulator for a couple of months, I noticed a decrease in effectiveness, and upon inspection, I realized that the pads had worn out and needed replacement. This added extra costs over time, which was a downside for me.
  2. Supplemental Exercise Needed: Although the Vital Flex Core Ab Stimulator effectively targeted my abs, I discovered that it wasn’t a comprehensive workout solution on its own. I still needed to incorporate additional exercises to achieve full-body fitness. For example, while the stimulator helped strengthen my core, I realized that it didn’t address other muscle groups or provide cardiovascular benefits. As a result, I had to spend extra time and effort performing supplemental exercises such as cardio workouts and weight training to ensure a well-rounded fitness routine. This need for additional exercises was a downside for me as I had initially hoped the stimulator would offer a complete workout solution.
  3. Time Commitment for Results: When I started using the Vital Flex Core Ab Stimulator, I found that achieving noticeable improvements required a significant time commitment. I had to dedicate regular, extended sessions to using the device, often spending extra time after my regular workouts. This demanded consistent dedication from me, which sometimes made it challenging to fit into my busy schedule.
  4. Targeted Muscle Group: As I continued using the ab stimulator, I noticed that it primarily targeted my abdominal muscles. While this was beneficial for strengthening my core, I also realized that it left other muscle groups underserved. For example, my leg muscles and upper body didn’t receive as much stimulation from the device. To address this imbalance, I had to incorporate additional exercises into my routine to ensure a more comprehensive workout for all muscle groups.
  5. Individual Variability in Results: Despite my dedication to using the ab stimulator regularly, I observed that the results varied among individuals. Factors like genetics, diet, and lifestyle played significant roles in determining the effectiveness of the device for each person. For me, I noticed moderate improvements in my abs over time, but I couldn’t expect the same results for everyone. This individual variability made it challenging to predict the outcomes accurately and manage expectations accordingly.

I kept the original clear protector sheet to keep the pads from collecting dust in between uses. I definitely feel the difference after a good session, and am nowhere near the max settings.

I’m actually really impressed with this unit . Great value for the money . It even came with a zip lock bag full of extra gel pads . I bought it to use more like a TENS unit. I have a TENS unit that isn’t very easy to set up or adjust. This feels exactly the same, but has such an easier set up and is so easy to program and use. It is not cumbersome to wear and walk around or multitask while wearing (especially compared to what my TENS unit entailed with a device with multiple cords and leads). Super easy to wear around the house while doing other things. It is very strong even on the lower settings . I like the variety of pulse mode settings . I believe it has a 20 minute auto off setting. As well as will shut off after 3 seconds if it doesn’t detect the gel pads adhering to skin. I’m not exactly sure the effectiveness this unit will have in regards to toning abdominal muscles but don’t let that deter you from purchasing.

So have been using Vital Flex Core off and on for a month or so, and even with that infrequent use, I feel that I have received some benefit. I think that my abs are a little more pronounced but nothing like in the photos of the advertisement.

So today I was pushed to write a review. I have been on level 7 for a while now (at least the last 10 sessions or so). I decided that I would move up to level 8. Man, after almost doubling over after 3 or 4 bursts, I immediately returned to level 7. So it definitely packs a punch the higher you go. Maybe after another 10 sessions on level 7 I will be ready to move up.

So, if you’re looking for one of these, I would highly recommend this one. And it will work if you use it consistently and watch what you eat (which is always the case). But you have to use it consistently. It can’t just be another one of those pieces of exercise equipment that you use a couple of times and then store in the closet with all the other ones that you bought. Maybe I’ll take a picture today so that I can update this review in a few months.

Vital Flex Core does what you expect it to do, that meaning zap the hell out of whatever muscle group. Easy to charge and replace the goo pads. We’ll see about long term effects.

I had tried using a couple other ab belts/stimulaters and they really didn’t work and broke the first couple weeks I had them, so I was very skeptical.The first time I used this, I could really feel it and that was on low levels. I have been using this for over a week along w/ regular exercise and I definitely have toned up more than a normal week w/o this product! I wear it while riding my bike and my muscles feel like I’ve put in a full workout!While one of the arm/leg pads was defective upon purchasing- I contacted the seller and not only did they set things right, they did so w/o a hassle and were extremely cordial.I’m very pleased w/ this product and highly recommend this if you’re looking to tone up along w/ regular exercise. Also, this is a company that stands behind their products so you can be guaranteed that you will be taken care of!

It's similar to the physical rehab Tens systems.

it’s a Tens pain product. That said it is a soothing product if you tone it down. It can cause discomfort at first. The oscillating shocks stimulate and sooth sort of. It takes some time to diel it to your comfort / desired level of discomfort. It’s an electric shock stimulus. very good if you got the hours to live with it

Wear it a little low (away from the stomach). This thing has several modes and even at the first power level, it will really get you. Wearing it high may cause a spasm and cramping. It’s definitely great and having low body fat will make it flex your abs very hard. Takes some getting used to, but you will be sweating quickly. I can’t say exactly what the caloric burn is but it is surely much more intense than doing crunches or situps or leg ups on a dip bar.

I have been using this Abs Stimulator for about a week now. I use it daily, for about 20 minutes, and vary the mode and intensity 2-3 times. I do my regular workout in the mornings and then use this while working at my desk in the afternoon. I can definitely feel the difference in that my abs feel like I did quite a bit of extra crunches or sit-ups. I’m looking forward to the results I expect over more time and I would suggest giving this device a try!

Bought this as a muscle stimulator but have mostly been using it for muscle pain after long hikes in the mountains. This item performs phenomenal when my legs have been insanely tight and need a little alleviation.Items easy to carry along on my hikes also since its doesnt weight that much. Fits right in my backpack without taking up much space!

Vital Flex Core definitely works. I saw result (my arms) in 3 days . it says use for 15 minutes 2 times a day. I used it for 1 hour 3 times a day a saw a noticeable difference in my bicep muscles after 3 days. the only complaint I have is the pads( not the gel pads,rather the pice you attach the control puck to)have a tendency to break/become defective. seller replaced them quickly. other than that fantastic product.

It’s just like going to physical therapy. You can adjust the pulse pattern and the power. It’s self adhering so I can move around the house. It has auto shutoff in case you fall asleep. Also I’ve used it a dozen or more times and haven’t had to recharge it yet.

Product offers a great workout and good quality for the cost. My only complaint preventing it from 5 stars is the lackluster instruction manual which I have pictured, which includes pictures of products that arent included to begin with, and vauge directions of use on the items that are included. Supposedly there are up to 8 different Modes, and i can flip through them, but I have no idea which ones are best suited for my needs because there is no explanation for any of them.

I just got Vital Flex Core and started using it but I can definitely feel it and I think it will make a difference! Once I felt comfortable using it and got everything charged and ready to go I wore it for two hours on my abs and changed through the different modes. I wore it while I was doing household chores and it was comfortable, but I could definitely feel that it was working.I would definitely recommend and I’m anxious to see the results after giving it at least a couple weeks.

Vital Flex Core is really easy not only that but you get extra gel pads. I just started about 8 days ago and it’s worth it. I’m just chilling watching a movie and I get good results. If you want better results I’d suggest for you to workout daily and have a healthy diet.The abs simulator is ver comfortable and easy to turn on by just clicking a button or 2.this simulator has 2 modes which I’m really happy about because I get to choose which one I like best.
