Ab Belt Reviews – Which is the Best Ab Belt?

Slendertone Ab Belt vs The Flex Belt

Comparison Review for Each of these Ab Belts

At first glance, the ab belt offered by the regular Slendertone System-Abs Muscle Toning Belt line and their advanced  Flex Belt alter ego seem like the lazy way to get flat abs.

But it just so happens that there are many people who simply can’t do hundreds of crunches – or they have done so but still aren’t getting the results they want.

Both the are wide belts which are worn directly on your bare skin to firm and tighten your abdominal muscles. Whether one is actually better than the other is what we will help you to decide here.

  • Key features are listed for each

  • The specific differences between the main Slendertone product and Flex Belt

By the end of this review, you will also see some actual user reviews to check out and those should help you to come to your own informed conclusion about this gadget.

Ab Belt Technology

The way that BOTH of these abs belts work is through the use of EMS, which stands for Electrical Muscle Stimulation.

EMS has been used for therapy and to rehabilitate injured muscles for over 50 years. Hospitals, doctors and many therapy clinics use this.

With EMS, it the electrical pulses goes deep into your tissue and also affects the nerves that surround the major abs muscles.  The network of nerves causes your ab muscles to contract and relax naturally, working all of the muscles at the same time, not just those directly under the gel pads.

It will stimulate your Abdominus Rectus (upper and lower); Obliques (sides); and Transversus Abdominus (deep girdle muscle).  See below


I can tell you from my own experience that EMS therapy was very key to rehabilitating my own neck and upper back injury.  I know without a doubt that EMS helped me to recover by strengthening my muscles and helped to ‘fix’ my neck. So I personally have experienced how this technology can work effectively on any area of the body.

Key Features of  these ab belts:

  • Both use clinically proven EMS technology
  • First ab belts using medical EMS to be FDA approved as class II medical devices
  • Strength training intensity levels 0-99 and up to 150 on the Flex Belt
  • Have 7 to 10 customizable toning programs, with varying duration and pulse rhythms
  • Rechargeable controller and charger
  • Fits waist sizes 24″-47″ (Flex Belt belt fits up to 56” with extender included)
  • 2 Year Warranty

What are the Main Benefits?

If one of the following describes you, you might find that you would benefit from one of these products:

● Person who dislikes exercising and/or sweating
● Fitness enthusiast who is not getting enough success from doing crunches
● No time for exercising the abs every 2nd day the traditional ways
● New Mom’s looking to lose baby fat but can’t exercise yet
● Person with physical limitations (back injuries)

Pros of using one of  these abdominal belts:

● Can be worn while you watch TV or do other things like chores around the house
● Interchangeable control unit; works with mini belt systems
● Easy to follow plan
● Comfortable belt, fit to your waist size
● Very portable – can be used by those who need to travel a lot
● Doesn’t take up space in your home like exercise equipment does

Cons of both these ab belts:

● Can cause muscle soreness after use – just like real exercises can
● Gel pads need to be replaced when they start losing the ability to stick
● Remembering to recharge the batteries so it’s ready for use
● Cost of the device may not be affordable for some people
● Does not provide you with any cardio benefits like regular exercise does
● Secondary areas are not getting toned as with regular exercising


What are the little differences between the Flex Belt & Slendertone Ab Belts?

Flex Belt ABS system comes as just one model and was designed for both men and women. To learn more about it, read my full post here: The Flex Belt Review

Slendertone has belts designed just for women, just for men and unisex belts. There are 3 different models:

  1. Flex Pro Abdominal Muscle Toner
  2. Ultra Abdominal Muscle Toner
  3. System Abdominal Muscle Toner 7P with rechargeable controller

The same parent company, Bio-Medical Research Ltd out of Galway, Ireland is responsible for BOTH product lines and brands.  It is their 50 years of perfecting EMS technology that goes into these products.

The Flex Belt has a higher price point at $199 versus the Slendertones starting price of $79 for the Flex Pro.

ab beltFlex Belt’s higher price is due to the use of some technological advancements and other enhancements over the Slendertone belt. Such as the external rechargeable battery pack, whereas the Slendertone pack is built into the belt.

It is 50% stronger and goes up to an intensity setting of 150 while the Slendertone System Abs 7P intensity can only be adjusted from a range of 1 to 99 or up to 130 on the Ultra model. Once you have achieved nearly super-fit abs, you would probably want to go beyond just the 99 setting.

Also, the Flex Belt has 10 different training programs but the Slendertone System Abs 7P has just 7 programs.

What Cosmo Magazine Reader’s Said:

Since the Flex Belt has become so wildly popular, even Cosmopolitan Magazine readers wanted to know more about it. So they actually conducted their own 4 week trial where they invited their readers to test it out.  Here’s what they found out:

  • 100% of users said it worked in some way
  • 96% of users said they would continue to use The Flex Belt
  • 92% of users say is easy to fit in with their daily routine
  • 81% of users reported firmer stomach muscles in just four weeks

The Bottom Line

Remember, since these products only target the abs and do not provide total body fitness – you should do some other exercises to tone your body all over. Especially if you want to lose a lot of fat.

After all, these belts are only working out your mid-section.  But for that single purpose, these are really great products.

flex belt reviewsWith the Flex Belt, Bio-Medical Research smartly came up with a more premium product and gave it a new name to separate and distinguish it from the rest.

This helps to build greater appeal to those who can appreciate the value of a higher end product.

If you decide on saving a couple of bucks by going with the Slendertone System Abs 7P belt (it’s $139 on Slendertone’s site) you will still get a very good ab belt.

Just be aware that there will be greater limitations once your abs get stronger.

Really, you should balance your buying decision between what you really want for yourself and what you feel you can afford.

If you can afford the The Flex Belt – I say go for it and take advantage of extra intensity and also longer lasting gel pads due to their higher quality compound.

BEWARE of shopping on Ebay to get a deal for these belts!  There have been confirmed reports of knock-offs and poor quality fakes being sold there.

Stick with a reputable retailer like Amazon as they work with trusted retail partners.

You can review different pricing and more information about the Slendertone 7 Program Abdominal Muscle Toning Belt (Unisex) by visiting Amazon.  They always have great prices and offer FREE shipping (in the USA). Plus Amazon has way more model options than other retailers as well terrific low prices every day and free shipping too.

Good luck with your abs toning!
