Flex Belt Overview

Alright, so it’s time for my no BS review of the Flex Belt. I’ve been posting here for a while, and I’ve written lots of overview posts of how I use it, what I think of the equipment and features, but a full review is long over do. Read my Flex Belt review to know it SCAM or not.

In a hurry ?

For those of you who don’t already know this device is manufactured by Slendertone and is very similar to the Slendertone System Abs. From what the official site says the Flex Belt is the “high end” version of the system abs belt with more intensity levels (0-150 VS 0-99) and more programs (1-7 Vs 1-10) plus a few additional bonus items you get when you order direct from the official website (dieting software, magazine subscription etc.).

I don’t place much value in the magazine subscription or the dieting software. I know it’s what all the other ab belt companies are doing (ex: contour provides workout routine and dieting plan when you purchase their belt as well) but lets face it you’re either interested in leading a healthier lifestyle or your not. If you fall into the later then you can probably just stop reading this review right now because you’re not going to like what you’ll hear.

How Flex Belt Works ?

So just as a quick overview of how the Flex Belt works for those of who are reading this just after seeing the infomercial on TV or haven’t done any research on this device yet.


This belt, and others similar to it, use technology known as electronic muscle stimulation, or EMS for short. It’s been used for years by physical and physio therapists to treat muscles in patients that may have atrophied from lack of use or been in an accident and require recovery of their muscle mass and strength. In this medical environment EMS technology has become the industry standard and is proven to work.

Electronic Muscle Stimulation

gel-pads-flex-beltThe basic concept is a slight electric current is sent through your skin into the densest area of nerve endings connect to your muscles. This electric current when “ON” (there’s both an on and off mode to all EMS devices) causes the muscles to flex or contract in a similar manner to if you flexed your abs or bicep. When the EMS is “off” the contraction stops. So each on and off cycle is sort of like a repetition if we were to use workout lingo.

How is the electrical current sent through your skin? In a physical therapists office he would have a small machine with wires that connect to gel pads that would “suction” to your skin with the help of a jelly like substance known as contact gel. In an ab belt there are just gel pads that are moist and sticky and thanks to the belt being completely wrapped around your waist they’re able to make great contact without the need of any gel (although I have seen on ab belt that uses contact gel still, kinda messy yuck!).

So that’s the simple version of how The Flex Belt works and how it flexes your abs and makes them work. Lets move onto the actual experience using the belt.

Using The Belt

Flex Belt says that using their EMS belt 5 times a week for 6 weeks will guarantee results. So much so that if you’re not satisfied with the device you can request a full refund within the first 60 days. While I haven’t exercised this right, I have been in contact with Customer Service and I can say there are real people on the other end, which is good news. So I’m sure they’d deliver on this guarantee should you want to take advantage of it.

The belt is easy to use, the difficult part is being consistent in using it. I say this from experience. I go through bouts where I use it 5 days a week at the office for a couple of weeks, and then it will sit in the corner for a week and I won’t put it on. Surprisingly, if it’s sitting in the corner, I’m not getting a flatter stomach 🙂 .

Create a Routine

The best advice I can give anyone who buys this belt is to create a routine around it. Try and use it at the same time every week day and then take the weekends off. Since most of us work Monday to Friday it’s easiest to create a routine during those days and then give yourself freedom on the weekends. It takes 20-30 minutes to complete a session so using it in the morning before work, on your commute or even at the office would work.

Flex Belt customer review

There are a couple of reasons why I like this abdominal belt over others that are available.

  • The first is that it is small and compact. You could get away with wearing this underneath a sweater if you wanted at work and no one would know it’s there.
  • The second reason is that it has a really sleek wired remote that also doubles as the rechargeable battery for this device (most EMS toning belts take AA or AAA batteries).
  • The third reason is because it offers a wide range of training options with 150 different intensity levels and 10 different workout programs. It’s just all around a more versatile and full featured ab belt compared to any other device available right now.

Is it Safe?

The Flex Belt is FDA cleared for use as an abdominal stimulator, so this tells us that the FDA thinks its safe. However there are a few disclaimers that they like you to know about. Such as if you recently gave birth then you must wait a minimum of 6 weeks before starting to use the device and you should check with your doctor. If you had a caesarean in the last 3 months your doctor must approve use of the belt prior to starting on a program.

What Does the EMS Feel Like?

The sensation of EMS is like a slight buzzing or warm feeling. I personally don’t’ feel discomfort, but I can feel it working my abs, and on days where I really push the envelope with the intensity level I have a bit of soreness afterwards. However that’s a result from the workout in my opinion not serious side effect of EMS.

Does Flex Belt Work?

I know on their official website there’s a fancy video with a PhD talking about the clinical studies and trials that have been conducted on flexbelt. This is great, but lets talk real life scenario.


Without a doubt the Flex belt strengthens, tones and firms your ab muscles. My abs are stronger and firmer then they were when I started using the belt and just based on the fact that I started at intensity level 40 and am now working my way closer to 80 tells me that my abdominal endurance has increased. OK, so that’s all great but do I have a flatter stomach? Well I think so yes, however I don’t 100% attribute that to the abdominal toning belt. You see the Flex Belt doesn’t burn belly fat it strengthens and tones muscles. That’s only one part of the six pack abs flat stomach equation.

The Weight Loss Equation

The other half of the equation is diet and exercise. So if you’re a pretty thin person already chances are you’ll see some visual results in a few weeks without doing too much else. However if you carry a bit of weight around your stomach (don’t feel bad like 99% of us do too) then you’re going to need to do a bit more for yourself then just wear the toning belt every day.

Get out and start walking, jogging, bike riding or swimming. Something that will burn more calories for yourself then you would normally just sitting at your desk all day. Also cut out the soda pop and snacks. Replace that with water and fruits or veggies. Trust me on this. I know dieting sucks, but this small change can make a big difference. How? Well soda and snack foods are about the most calorie dense foods we eat. Water and fruits are not and they offer a ton of other great things our body needs. This small change will reduce your caloric intake and likely cause you to drop some water weight if you haven’t been drinking 6-10 glasses of water each day. The cardio exercise will burn extra calories, so the equation goes something like this

Reduce the calories your eating now + burn more calories with cardio exercise = calorie deficit each day so you lose some weight

Now this isn’t the perfect science of it all, but it’s the basic idea. If you’re getting out and being active, not eating a bunch of crap, watching your portion sizes at meal time and not snacking on junk food you’re gonna do good with this.

Flex Belt before and after

Here’s some images from users who used flex belt a time.



What are the intensity levels like

The intensity level in the belt is increased and decreased using two up & down arrow bottoms on the front of the remote. You can adjust the intensity on the right and left side of your belt independently of each other. I always kept the exact same intensity level on both sides to ensure I was giving my abs an even workout each session.

remote-intensityWhen I first started I began just under intensity level 40 and increased it every few days. I wasn’t too sure how I would feel after the workout at first so I was hesitant to just jack the intensity, however I quickly moved up to 70 and beyond after a couple of weeks. The intensity level you feel comfortable with is going to vary from person to person. The important thing is that you try and always workout on the highest intensity level you feel comfortable with. This ensures you’re getting the most effective workout each time.

While I haven’t broken the 100 level barrier yet, it’s nice to know that I’m only a little over half way through the potential power the belt offers. So there is still lots of room for improvement and results as I continue to use the Flex Belt.

What are the programs like

Programs basically are different variations of how the EMS turns on and off and for how long. So for example in the Beginner program the EMS turns on for 2-3 seconds and then turns off for a about the same time. This continues for the full 20 minutes. As you progress different patterns are used for how long the EMS is turned on and off and for how how strong an intensity is used. The higher programs work your mid section harder not only by being a more intense workout but also varying how the EMS flexes your abs.

Each program includes a warm up and cool down phase. The warm up prepares your muscles for the main part of the session and the cool down will relax your muscles prior to completing your session.

Here’s the details on the programs that are included with the belt:

When you first take your belt out of the box it’s set to program #1, Beginner. The belt will automatically progress through the different programs up to program #6. To access programs 7, 8, 9 and 10 you must manually select them using the program button on the remote.

The toning power column references how effective the muscle workout is during that program. The higher the value the more effective the workout.

With each program you manually set the intensity level and you can also adjust the intensity level through out the session (you cannot change programs once you start, you must shut the belt off and choose a new program).

Personally I’ve gone through the first 6 programs. I’m now using program #7 and am going to bum up to “ab power” which is program #8 next week.

Flex Belt Pros & Cons


Flex Belt Price

I like The Flex Belt, in my opinion if you’re going to own an ab belt, this is the one to have. I like it because it’s concealable under clothing, has a rechargeable battery, has 150 intensity levels, 10 workout programs and more.

The price on Flex Belt is a bit more then the competition yes (around $200 regular price) but I’ve got a couple of coupons you can use to reduce the price so that helps.

Is Flex Belt Scam ?

I, personally, thought that The Flex Belt was a scam when I first heard about it. To be perfectly honest with you, I still thought it seemed fishy after watching a video of how it works on You Tube. I have a love/hate relationship with exercise and am always curious to learn about new products. And especially since I started a new job last year that had me sitting at a desk almost all day long, I realized something: I would have less time to exercise but suddenly needed it way more. I think I finally understood why my mom was always watching the Home Shopping Network and getting products she would use once and then store in our basement and sell at our annual garage sale. I had the best of intentions – not to get fat, to stay in good shape and maintain my love of working out – but didn’t always have a way to achieve my goals.

I should mention that even at my heaviest, I was never enormous or anything. But I was overweight, according to one certain video game machine program I used. That made me crazy. Because during my early adulthood I had worked hard to get into better physical condition and finally liked how I looked in clothes and swim suits. It happened pretty soon after I started a job that required me to be on the computer and sedentary for hours every week. I developed some tummy flab and jiggle on my bum and thighs. It’s typical, I guess. But I didn’t want to settle into that, you know? One size larger and feeling uncomfortable in my body was the worst. I was determined to find a product or machine that could give me a really decent workout in the shortest amount of time, since I could not make it to the gym as often as I had in the past.

Like most of my friends with a similar situation in an office job, I had more than ample free time to goof off on the internet. I tried getting out the office and walking during breaks, but I could tell that made me seem less committed to my company and work, which I didn’t want. Instead, I could research. And there was a lot of information to uncover about burning calories and fat, toning, all kinds of diets, some of which looked interesting and others I immediately dismissed, and products that I initially chalked up to be junk, either for lazy people or people too dumb to see through the scam and advertising. I was not one to jump on the bandwagon for The Flex Belt, or any product like it, but I have to admit, I kept going back to look again at the process of using it and the results that others were getting.

So, for those of you who haven’t seen the very loud, kind of annoying promotional videos – TONE IT! TIGHTEN IT! FIRM IT! – The Flex Belt is a device, I guess, that you wear around your waist and it uses electric pulses to move the muscles in your abdomen, the same thing that happens, apparently, when you do a proper crunch or sit-up. Seems too good to be true, right? Like the “eat all the cookies you want diet” or the pill that promises you won’t have to change a thing about your diet or do any sort of exercise and magically, you will get skinny.

The thing about The Flex Belt, is that when you read more deeply into it, they do talk about fitness and healthy eating, and all that stuff we all know is important but sometimes wish we could ignore. I personally, love the cheesy bread from a certain pizza chain we all know and could eat it every night if I could not get majorly chubby doing so. Anyway, this was enough of a positive sign for me to want to learn more.


Turns out, The Flex Belt is most recommended for those of us who are already doing something to get into shape or to stay fit and active. At my busiest at work, I still have time to walk for thirty minutes a few times a week, usually in the morning, and to hit the gym occasionally, where I know I burn a lot of calories. My diet had deteriorated, though. For a while I was eating mostly vegetarian – though I love a good burger once in a while – and getting lots of whole grains and doing salads for dinner most nights. I realized my “work eating habits” had gotten unhealthy and gross. It was so easy to say yes when everyone else was getting bagels or muffins or donuts, and ordering chips to go along with my turkey sandwich at lunch. I knew I wanted to make some changes, so I began tweaking my caloric intake, just a little at first. Nothing drastic, but choosing to drink water instead of juice or soda, these are the small choices I am talking about that made a big difference, at least for me.

I can say I saw some improvement in how I looked in my clothes by eating better, but I was definitely flabbier than I used to be and I continued to find that depressing. I was bummed out I could not affect the change I wanted to see, even though I was busy all the time at work and not like I was just watching TV at home all day or anything. I think this was when I decided I would give The Flex Belt a try for myself. I didn’t tell anyone about it. I thought my friends would make fun of me, especially because I was always calling them out on going in for fads and scams they found on the web. I am definitely “the practical one” and didn’t want to ruin my reputation and my ability to tease them about the junk they bought and believed in for the sake of a quick fix.


What totally surprised me – in a good way – about the first time I used The Flex Belt, was that when I was done my stomach muscles felt like they had been worked, like I had done Pilates or a serious crunch routine. The sensation while you are wearing it is not unpleasant. It doesn’t hurt at all, I guess it felt funny at first but I very quickly realized I could get other things accomplished. I could talk on the phone to my mom or sister, read a magazine, clean the garage, or even walk around the house, in the hopes of burning even more calories while I was toning. And I did feel like I was toning. It’s not like you’re going to lose your Buddha belly in one day or anything, but you feel the belt kind of vibrating and afterward you know you’ve had an ab workout. It took a couple of weeks of using The Flex Belt every evening after work, but I soon began to see the results I had not been seeing just from occasional exercise and consuming less junk food.

It was time to come out of the closet, LOL. I told my mom and my best friend about what I was seeing and feeling. They knew I was not one to take weight loss lightly. Being thin was never easy for me, always work. And once I was resigned to being healthier, I always stayed focused on my daily practice and long-term goals. They were pleasantly surprised, I think, to hear me admit that The Flex Belt was a product worth using. That it could not be lumped in with those sites and salespeople that make big promises assuring the consumer we don’t have to do anything. You have to be a little proactive. You have to have a healthy diet, you have to get some cardiovascular exercise, and you have to use The Flex Belt consistently and correctly.

I don’t know. I mean, I can see why it wouldn’t be right for everyone. But most of my friends and family have been excited to try it and liked the results, both immediate and over time. And I know I am definitely looking slim and trim again, instead of roly-poly. I love the confidence I have back. And for the first time in a very long time, I love my abs. My ab muscles are seriously tight, and I think I am beginning to get a six pack, which is a goal I never even thought I could get for myself. Even at my most fit I always had a little belly pudge. Not anymore. I have flat abs and I feel so fantastic. Now I am happy to admit it. I was skeptical and now I am a believer. The Flex Belt is not a scam, ‘cause it really worked for me.


What really matters as to whether you should or shouldn’t buy this device is if you’re prepared to put the work in or not. Are you going to use it 5 days a week? Are you willing to make the lifestyle changes to reach your maximum potential results? If you answer yes to this then I say get it! They’ve got a 60 day guarantee on this thing so if you’re not absolutely amazed with it you can send it back and request your money back in the first 60 days.
