Flex Belt Review: What Personal Trainers Don’t Want You to Know

Does The Flex Belt Work?

This is the exact question we aim to answer in our Flex Belt review. We’ve read a lot of Flex Belt reviews (who doesn’t read reviews?), and we wanted to see if this belt was able to live up to the hype.

The Flex Belt actually surpassed our expectations in a lot of ways.

Our Flex Belt Review

Flex Belt is simply the leader in the electronic muscle stimulation belt industry – really. The difference that this product offers over the competition is that it’s really FDA cleared. We’ve had the pleasure of reviewing a lot of belts that say they’ve passed the rigors of the FDA, and a lot of claims can’t be backed up.

But you can see for yourself that this belt is FDA cleared. It doesn’t get any more official than being on the FDA’s own website.

This was the first indicator that this product works. Don’t get me started with all of the celebrity endorsements either. This belt has been endorsed by some of the hottest celebrities on the planet, including:

  • Denise Richards
  • Lisa Rinna
  • Adrianne Curry
  • Jerry Rice
  • Janet Evans
  • Brian and Jill Wade

And the belt has been featured in Marie Claire, Cosmopolitan and countless other publications. All of this led to the light bulb illuminating in our minds that this may be the one belt that actually is able to meet the claims.

How the Flex Ab Belt Work

The Flex Belt is the only FDA cleared EMS Belt available

We’ve reviewed a lot of EMS (electronic muscle stimulation) devices, and the way that this belt works is very similar to the competition (but it actually works). The technology has been used for thirty years, and the way it works is simple.

Electronic currents are directed at the abdominal muscles.

The right current and frequency level will cause the abs to contract. You can even see the abs actually contract on the official website. Approximately 150 contractions are produced per minute when using the Flex Belt.

And boy will your abs be sore after the first session.

All you need to do is use the belt for 30 minutes per day to see results (check out Flex Belt results and testimonials for yourself).

Flex Belt Results

The Flex Belt before and after pictures demonstrate that this product really does work. But what are the studies stating? This is something that many companies don’t offer – scientific studies.

Over 2 million people have used Flex Belt, so there is a lot of data to go off of.

The company conducted a study at the University of Wisconsin that worked with participants for a period of 6 weeks to see what results they could achieve. The results were:

  • 100% of users felt their abs were firmer and more toned
  • 92.3% felt that their ab muscle firmness increased

Results are amplified with a proper diet. If you’re eating right and exercising, you’ll be able to achieve the washboard abs and six pack that you’ve always dreamed of having.

But if you think you’ll be able to eat a Big Mac and fries daily while consuming more calories than you’re burning, no product in the world will work to help you get abs. Sure, the Flex Belt will help you strengthen your abs, but unless you lose the fat that is covering your abs, they’ll never be visible.

Results can and do come to the majority of people, but be prepared to put some work into really achieve lasting results.

Programs and Intensity Galore

You’ll never find the Flex Belt lacking in the program and intensity category. The belt goes to a whole new level of intensity, which is why it works, while the competition is simply a cheap comparison with little-to-no results.

The magic happens with:

  • 150 intensity levels
  • 10 toning programs

And everything is backed by a 2-year warranty and a 60-day money back guarantee. The belt doesn’t work for you? Return it and move on with your life while not losing any money in the process.

The 150 intensity levels go from barely any intensity to a jolt that offers a very intense contraction. Keep in mind that the intensity is so high at the 150 level that you’ll need to work your way up gradually to see results. If you go to the highest level, you may find that the intensity is so high that it may be painful.

Most people seem to stop at an intensity level of 80 – 90 because it’s so strong.

When you go to choose a program, there will be 10 available for you to work through:

  1. Beginner: 20 minutes
  2. Intermediate: 25 minutes
  3. Advanced: 30 minutes
  4. Expert: 30 minutes
  5. Pro 1: 30 minutes
  6. Pro 2: 30 minutes
  7. Ab-Power: 30 minutes
  8. Endurance: 40 minutes
  9. Crunch 1: 3 sets of 10
  10. Crunch 2: 3 sets of 10

You have the option to mix up your workout for best results. This is really like stepping into a gym and working your abs yourself.

After the first 8 weeks of usage, you can use the device 3 – 4 times a week to maintain your results.

The belt even has an automatic shut off feature that will allow you to save battery life if you forget to turn the unit off.

Note: The belt is sized to the user due to the placement of the pads, this means only one user will be able to use this belt at a time (unless you waste a lot of pads along the way).

Flex Belt Vs Slendertone

What’s the difference between these two belts? The same company (BMR) actually manufactures both of these products. The Slendertone is a newer product, and this product does not come with the FDA clearance like the Flex Belt.

But Slendertone does offer an app, which is nice.

Overall, these are both great products, with the Flex Belt holding the edge over the Slendertone.


  • FDA cleared and the only belt listed as approved by the FDA.
  • 2 million happy users with results and positive reviews.
  • Highly studied and endorsed, so you know it works.
  • Minimal Flex Belt complaints.


  • Higher priced than the competition (most of their belts don’t work).

A lot of people balk at the Flex Belt price (just under $200), but it’s one of the only belts on the market that actually works. The EMS units that physical therapists use are far costlier, so it makes sense that you would need to pay more for an ab belt that really works.

After all, why waste your money on products that don’t work?

Our Assessment

The Flex Belt reviews didn’t lie: this belt works. Not only does it cause your abs to contract, but the belt provides you with substantial results in the process. You’ll lose inches on your waist and will have a tighter stomach – that’s almost guaranteed.

If there is one product we would recommend at the highest level, it’s the Flex Belt. We rate this belt a 5 out of 5 stars. Even Amazon reviews brag about how well this ab belt works.

Anyone trying to strengthen their abs and see trimming results will not want to pass this belt up. It really works, and if you maintain a healthy diet to lose fat around your gut, you’ll experience the results even faster.
