About Flex Belt

When watching TV recently, we saw a commercial for the Flex Belt, which claims to use medical-grade toning technology to give you tighter, firmer, and flatter abs.

In fact, by using Flex Belt whenever you can, including at home or in the office, the company claims that you can experience these benefits in just weeks.

With this said, let’s put our thinking caps on and ask ourselves the following: Does the Flex Belt really work as well as it claims? Why or why not? And ultimately, is it worth your hard-earned money? We did some digging, and here’s what we found.

How The Flex Belt Works

Endorsed by Denise Richards, Lisa Rinna, Adrianne Curry, and others, the Flex Belt is hard to ignore. Why? Because by sending electrical signals to the nerves in your abdominal muscles, it claims to use patented, medical-grade abdominal toning technology to firm and strengthen them.

What’s more, the product claims that this can be performed wherever it's comfortable, including at home and work.

The Flex Belt promises to accomplish this by using three gel pads that send signals to all main areas of your stomach muscles, including upper abs, lower abs, and obliques, thereby causing them to contract.

The company claims that this FDA cleared ab belt toning system only requires one 30-minute session per day, during which your abdominal muscles will be contracted up to 150 times.

Flex Belt can be used by men and women of any fitness level, and claims to result in no side effects. However, you should always check with your physician first.

What Can You Expect When Using the Flex Belt?

After putting on the Flex Belt, the patented, abdominal toning technology will stimulate nerves in your abdominal muscles and cause them to contract and relax. According to the Flex Belt website, the sensation is pleasant and involves a mild pulsing sensation. If you need to increase or decrease the intensity, this can be adjusted on a scale of 1-150.

The gel pads used in the Flex Belt are claimed to be medical-grade devices that adhere to your skin and are used to transmit the electrical impulses to your abs. According to the product’s website, these gel pads last about 30 sessions, and will eventually need to be replaced for maximum operation (more about this in the Bottom Line section).

By regularly using the Flex Belt, they claim that you can expect results within 4-8 weeks, and after reaching a level you’d like to maintain, you only have to use it 2-3 times per week.

Flex Belt Pricing and Refund Policy

Each Flex Belt system comes with three gel pads, a rechargeable power supply unit, a belt extension (if your waist size is greater than 44 inches), and an instruction manual. The per-belt price you pay depends on how many you purchase:

  • 1 Belt: $199

  • One-Year Magazine Subscription – Choose from one of the following: Fitness, Elle, or Maxim Magazine.

In addition, each Flex Belt includes a 2-year warranty against "defects in manufacture that arise from the correct use of the product in accordance with the product manual and instructions.”

What Do Other Consumers Have to Say About the Flex Belt?

Since writing our original article, two HighYa readers provided their feedback about Flex Belt, giving the device an average rating of 1.5 stars. One only noted “it can work,” despite providing a lower rating, and the other claimed it won’t do anything for your muscles.

Flex Belt had a higher 3.5-star average rating on Amazon, based on nearly 1,000 customer reviews. There, most compliments seemed related to effective results (stronger, tighter muscles), ease of use, and reduced back pain.

On the other hand, frequent complaints appeared to claim that it stopped working after a relatively short time (but outside the refund window), along with no results.

Important note: Our only goal is to provide all the information needed to paint a complete picture—not to insinuate you’ll experience any of the same with Flex Belt.

From a company perspective, Flex Belt is manufactured by Bio-Medical Research Limited (BMR) based out of Galway, Ireland, who also brought us the Slendertone ab belt. Their Slendertone division, headquartered in Hoboken, NJ, had an A- Better Business Bureau rating and one customer complaint as of 6/2/17, to which the company hadn’t responded.

What Does “FDA Cleared” Mean?

According to the FDA, a device is considered “cleared” after a 510(k) form has been submitted by the manufacturer, and declares that it is “substantially equivalent" to a device that is already legally marketed for the same use.” This does not mean, however, that it has been reviewed or approved by the FDA, or that any of its claims are substantiated.

We were contacted by a company representative who clarified the following:

“Once the FDA has done a comprehensive review they will indicate that the device has been “cleared” indicating that all FDA requirements [have been met] for placing that device on the US market. The FDA review includes a review of the claims made for the device.”

They were also clear to point out:

“Substantial equivalence” is the method the FDA uses to review and clear medical devices. A claim of substantial equivalence does not mean the new and predicate devices must be identical, but that equivalence has been established with respect to intended use, design, energy used or delivered, materials, chemical composition, manufacturing process, performance, safety, effectiveness, labeling, biocompatibility, standards, and other characteristics, as applicable.”

Has Flex Belt Ben Clinically Studied?

In their correspondence with us, the manufacturer also noted that their 2008 6-week clinical study involved results compiled from a satisfaction questionnaire, which was conducted by Dr. John P. Porcari, a professor in Exercise and Sports Science at the University of Wisconsin-La Crosse.

Ultimately, 100% of participants reported that their abs felt more toned and firm, and 92% felt abdominal muscle firmness increased. Further, using isokinetic dynamometry and an ACSM sit-up test, a statistically significant improvement was noted regarding abdominal strength and endurance.

But Does Flex Belt Burn Fat?

With these positive results in mind, remember that the Flex Belt only stimulates, tones, tightens, and strengthens muscle, but it won’t burn fat.

This is important, because even though your stomach muscles may be stronger and more toned, if they’re covered in a fat layer of from less-than-stellar dietary habits, you won’t be able to see them. Ultimately, this means that you’ll need to supplement the Flex Belt with regular exercise and a healthy diet in order to experience results.

Our Final Thoughts About the Flex Belt

This leads us to the ultimate question: Does the Flex Belt really work? According to this article, electrostimulation may help you tighten and tone your muscles, but it's something you'll need to do on a regular basis (like exercise) in order to maintain any results.

With this said, far and away the best way to lose weight and tone your abs is through eating right and exercising regularly; plain and simple.

However, based on the response from the company (which is always positive), along with what we learned during our research, it seems like Flex Belt could offer supplementary strengthening from the comfort of your home. And if it doesn’t deliver, the company stands behind it with a 60-day refund policy, less shipping charges.

    Performs as advertised

    • By Paul P.,

    I'm using it while writing this review. I used once the first day, then two sessions a day the next two days, a day off, and now.

    I also had started running again at the Y on December 23rd - before I ordered the Flex Belt.

    My diet is bad, but I am working on it.

    The point is my pants are already looser. I hate doing sit-ups, so any help in that area is good. I don't expect to see my abs like the TV models, just want to reduce the waistline. And it's already helping based upon running as the only activity like in my past.

    I ordered from QVC and paid $127 plus received two extra sets of gel pads.

    On TV they said you have to watch your diet and perform some aerobic activity. They were totally honest about the product.

    Don't think it works? Get one and crank intensity level to 100, tell me how that feels (and intensity level goes as high as 150).

    Ten different programs so you can get alternate workouts to keep those abs "guessing."

    Bottom Line: Yes, I would recommend this to a friend

    Flex Belt user for three months

    • By Chad B.,

    A little background, I'm a 47-year-old male who has severe back and knee problems in both legs. Exercise is near impossible for me due to extreme pain. I bought the Flex Belt about three months ago. I use as directed (1x/d) for about a month. You need to adjust the intensity to fit your level. You should feel your abs the rest of the day or you didn't use high enough setting.

    After the first 30 days, I went to a second. I added in jump rope and a walk in the evening while wearing for the second time for that day. Now be realistic here, you won't see 6-pack abs. But my stomach is tighter, doesn't stick out as far either. My GF noticed at night while laying on my side my stomach is tight without me flexing. This is three months in, using two times daily. Added to slight exercise, it works pretty well.

    Some back pain has subsided with the stronger abs. That's really what you should expect, stronger and harder abs, but NOT a 6-pack unless you diet and eat 100% correct. I hope this helps some of you decide!

    Remember, harder, tighter, and stronger, but not bodybuilder look.

    Bottom Line: Yes, I would recommend this to a friend

    Love it so far!

    This fitness belt is great and definitely worth the money! To those who are saying they didn't get any results, my guess is they didn't follow the directions on use, which is to be sure to use with proper diet and exercise! I have been using for about a week now, every day, once a day (with the exception of the first use, when I used it for two sessions in a row), and I am definitely feeling it, at an intensity level of 80, so far! You can feel it working your entire abs, center, upper, lower AND obliques! What?! I love it! Seems to be a quality fitness belt, on the contrary to what I read, above but may be too early to tell. I'll post again in about a month.

    Bottom Line: Yes, I would recommend this to a friend

    I'm excited!

    I recently purchased the Flex Belt, and after one use I'm quite excited about it's potential. I just finished using it for the first time. After taking it off and starting to move around, I could feel my abdominal muscles as if I had just done a bunch of sit-ups. That right there will keep me incented to keep using it.

    I used a fairly high intensity (130) and did the workout twice in one session as my abdominal muscles have never been firm in my entire life (I'm 49 now) and my belly is rather large. I don't expect miracles, but I do truly believe that this belt, along with diet and actual exercise, will help me achieve my goal of a smaller and more firm stomach area.

    Bottom Line: Yes, I would recommend this to a friend

    The Flex Belt

    Beware of this product. It is a piece of junk. Shoddy workmanship. A total scam. So badly constructed it fell apart immediately, and they won't take it back. Nasty customer service. All around terrible experience.

    It can work

    • By Damon,

    Anyone who thinks that this belt (or any other type of belt) is going to just burn fat shouldn't buy this. Yes, this works if you let it, but you need diet and exercise. This is like going to the gym and working out your stomach, that's all it is. Except you don't have to go to the gym, it just does it automatically.

    It's making you use your muscles, which in turn burn calories, which in turn tone your muscles. It's not a hard concept.

    Bottom Line: Yes, I would recommend this to a friend

    The flexbelt is a a major disappointment. It absolutely does nothing when used as directed.

    This company is stealing money from people like myself. Anyone who buys this product is acting idiotically.

    There are two guys sitting in a customer service room waiting to take your phone call and your money.

    Flex Belt is no better than buying a remote control car at Walmart. It will do NOTHING for your muscles

    Bottom Line: No, I would not recommend this to a friend
