Flex Belt Review - 10 Things You Need to Know

The Flex Belt is a belt that is strapped around your waist to target your abdominal muscles. They claim that even without exercising, you can get an effective workout for your abs without getting off the couch or leaving your desk. Can a belt really simulate the abdominal muscles as effectively as an abdominal exercise can? We love the idea- but admit to being skeptical.

While the FDA has approved this device, our research team wondered how well this product could work. Our research team searched for the effectiveness of this product and gathered user reviews. Here is what they discovered.

Flex Belt can be purchased through their Official Site.

Medical-Grade Technology That Works

This is where the science of the Flex Belt comes into play. What does it mean to be FDA-cleared? It means that the company behind the technology was required to prove the EMS unit worked. But, not everyone has faith in this fact, so let’s look at the clinical results.

According to a study published in the Journal of Sports Science and Medicine, “Strength improved by an average of 34% after 4 weeks and increased another 24% in the subsequent 4-week period.” You don’t have to do a thousand crunches to get more muscular abs.

The study went on to report, “For abdominal endurance, the stimulation group had a 100% increase in curl-up performance.” Reductions in waist circumference and abdominal circumference were also noted.

There are also studies in the Journal of Orthopaedic and Sports Physical Therapy, Archives of Physical Medicine and Rehabilitation, the journal Thorax, the journal Sports Medicine, and the journal Medicine and Science in Sports and Exercise that show the benefits of EMS.

Risk-Free, Money-Back Guarantee

The Flex Belt promises to work in four to eight weeks. To prove this, the company offers a 60-day money-back guarantee. So, you have clinically tested and proven technology that doctors have researched, and the FDA has cleared that you can use it without risk. There’s absolutely no reason to skip this offer – it’s a win-win situation.

Risk-Free, Money-Back Guarantee

We honestly don’t think professional athletes and major magazines would stand behind a product if it weren’t worth trying. Marie Claire and Cosmopolitan magazines have completed trials and challenges. Jill Wade, former Ms. Universe Figure; Brian Wade, athlete, trainer, and model; Jerry Rice, an all-star from the San Francisco 49ers; and Janet Evans, Olympic gold medalist, and World Record holder have all used, loved, and supported the Flex Belt over the years.

How Does the Flex Belt Work?

There are three medical-grade gel pads that you place on the abdominal muscles and external obliques. An electric current goes to the pads, which contracts the muscles in a smooth, comfortable manner. You will feel the tension (it lasts only a few seconds) and the gentle release. There’s nothing painful or irritating about the process.

Combine Flex Belt with your regular comprehensive exercise routine, and you are sure to get results!


What About Results?

The company guarantees results with the Flex Belt within weeks, but that’s not enough. 100% of users report a firmer, more toned stomach with just 30 minutes of usage, five days a week. 49% noticed an increase in strength, and 72% saw a boost in endurance. The best part is you don’t have to pack up and head off to the gym. You wrap it around your waist, wait 30 minutes, and that’s it.

What Users Are Saying

What Users Are Saying

“Works great! – I love this thing I tried sit-ups and crunches and it just never seems like my muscles are doing good boy right away you can tell you’ve worked your ads cuz you’re sore the next morning his thing is awesome.”

“Minimal results – The instructions recommend trying it on setting 20 for beginners, but I didn’t see any results until jumped up to about 115. Even then, mostly my sides would be minimally sore, even with over 45 minutes of daily use. This device could definitely give you results, but I think only if paired with consistency and additional abb workouts. Definitely not a stand alone product.”

  • What kind of batteries do you use for this belt. Rechargable or regular?

    What kind of batteries do you use for this belt. Rechargable or regular?

    • Riley

      this belt doesn’t require the use of batteries it plugs into the wall!

    • Caitlin

      the batteries are rechargeable from what i’ve researched on this product

  • Does this work on the same theory?

    In 1982 had to have knee surgery not before I had already lost the muscles in that knee. Surgery was micro. Had to have threarapy. The machine they used was of this concept to regain my muscles. They said at that time the Russian athletes used it to build their muscles. The process was electrobes connected to moisture on my leg. It would work and you could see my muscles enlarge with the currant. then release. Does this work on the same theory?

    • Karen Icenhour

      I was wondering I had a hysterectomy three years ago, will the Flex Belt help tone my muscles that are still numb.I am 47 years old and they say the older you get the harder it is to lose weight and inches.Will this help me?

      • Amilyn

        I have the same question! Does it help surgically cut muscles?

      • Caitlin

        even though you can’t feel those muscles anymore they still function and still need toning. if they didn’t you wouldn’t be able to hold yourself upright. the only thing the belt won’t fix is scar tissue left from the surgery if any.

      • Mark

        Also they may have removed several nerves in the process which create the “numb” feeling. It took me about five years for the feeling to begin to appear as the remaining nerve tissue regenerates from my hernia.

  • It's worth the money!
    Eboni (Verified Purchase)

    I’ve been using the Flex Belt for 3 wks and can already see a big difference in my abs and love handles..:-) I can’t wait to see how I’m going to look within 8 wks! It’s worth the money!

    • DS Admin

      Great to hear that!

    • angie

      It’s been a month now. How many inches did you lost? Does it hurt? How long is 1 session? I would love to get one too if it really works

  • Really works! For me
    Aria (Verified Purchase)

    After trying this product, I can say it really works!

    • Vivian

      Does this item just tone or will I lose belly fat too?

      • Vivien

        Does this work the same as “Slendertone Start” which had sticky patches to stick on the body

        • Tracy

          I just ordered stand gotit yesterday. It says slender tone on the box and yes it has sticky gel pads

      • Alicia

        The best way to lose belly fate is to tone the muscles underneath. The more muscle under the fat, the more it will help “burn” away the fat. But you may need to adjust your diet so you don’t retain that fat.

        • Rosslyn

          HI Alicia
          You sound like you know what you are talking about. Can you tell me what to buy as i need to loose fat around my belly desperately. I need to loose weight. Please advice me on what to buy or use.

        • walter

          the most effective way to loose weight is to envision yourself being the perfect weight and becoming that person it all begins with a thought if you’re constantly thinking about being overweight all youre doing is telling your brain that you want more weight instead if you think about the perfect weight then your brain goes to work to make it happen with diets exercise etc try it and you will see remarkable results is works 100% of the time.

      • ulene

        do u ship to jamaica

        • Anonymous

          yea they do.. it’s just an extra charge

      • nick

        tone= better defined muscle
        fat in an area makes those muscles less toned.
        so yes it makes you lose belly fat aka helps you tone your stomach. lol
