The Slendertone Ab Belt System, a.k.a. the Flex Belt, is a unique device that has been cleared by the FDA for toning and strengthening ab muscles using electro muscle stimulations. The Slendertone Ab Belt System was clinically tested and has different belt types available for both men and women. The clinical study were conducted by Dr. John Porcari at University of Wisconsin in 2004. There are no harmful side effects known or associated with electro muscle stimulations (EMS).

Slendertone Flex Belt Pros and Cons to Consider

Pros to Consider
  • Slendertone ab belt is discreet.
  • Proven to build stronger ab muscles.
  • Results typically seen in 8 weeks (according to company website)
  • 60 day money back guarantee.
  • Accessories are included with purchase (travel case, charger, and quick start guides).
Cons to Consider
  • Not everyone is able to benefit from electro muscle stimulation. For some of our readers, electronic muscle stimulation simply is not enough. Those with a relatively high body mass index will have to use the tone belt in conjunction with a healthy diet and moderate exercise to truly benefit from the Slendertone Ab Belt System. If used properly, the ab belt should show results.
  • FDA approval of the device is only for the safety of the device. Approval is not a guarantee that the product does what is advertised.

Flex Belt Product ImageHow Does the Flex Belt Work?

The Flex Belt works by stimulating nerves around the stomach muscles using EMS (Electro Muscle Stimulation). This stimulation causes the abdominal muscles to contract creating a similar effect and feeling of doing crunches. The Slendertone Ab Belt System is adjustable so you can increase the amount of stimulation over time to create stronger tummy muscles. The Slendertone Ab Belt website recommends using the product for 30 minutes a day (5 times a week) but the usage schedule can be adjusted to meet your fitness needs. This product is similar to the contour ab belt and abtronic belt but has a slightly higher customer satisfaction rate.


During the time of our review, the belt costs $199.00. Gel pads last roughly 30 sessions and some gel pads do come with the order. However, additional gel pads are $14.99 a set and will be required for prolonged use.

This works great for me, but someone pressed random buttons on my controller. Now, it only goes on for 3 mins & turns off. How do I extend the time back to 4o mins?

I am having a great deal of dizziness, and didn't realize at first that it was from this product. I am going to stop using it for a couple of days and see if the dizziness goes away. I will probably return this product, becuase of the dizziness. I had high hopes for it., but I don't think it is going to work for me - I also have a lot of belly fat.

so far belt is brilliant, but have noticed there is no electrical pulse coming from middle patch on my belt, only the sides! is my belt faulty or is this normal?

Just received my Flex Belt and tried it for the first time today. Having a high tolerance for pain, I put it on the Max...150 intensity at level 4 for 30 minutes. Loved it! Definitely strong contractions. Reminds me of the EMS my old chiropractor's office used on my back. Looking forward to seeing results in a few weeks. Wanted to point out that the Flex Belt is by Slendertone...just a different model. Has a higher intensity (150 Vs. 90) and more program levels. Best wishes and I'm very glad I made this purchase. Looking forward to seeing hubby's face when I get him to try it. ;)

Loose abs
I purchased the slender tone belt because I HATE sit-ups. I have been working on dropping lb's by cutting portion sizes considerably. I have been wearing the belt for the past 5 days. I have worn it 4 times per day and was concerned because i was worried that i might have jumped in too quickly and have been over using it. Abs are tight in the morning with very minimal muscle ache. I am up to level 115, and yes it can be a little uncomfortable but have been blown away by the results. It does not burn belly fat but it really does suck your stomach in. My pants are already looser and I feel more comfortable and confident in my clothes. You MUST incorporate exercise to realize the full benefit. This is my first on-line purchase of the sort and this is the first time I have left feedback on a site. Very expensive but i am beyond happy with the immediate results. Can't wait to see what happens in a couple of weeks. Just turned it up to 120 and and almost fell out of my chair. Friggen hurts. Best purchase I have made this year.

It's important to keep in mind that if you have a high BMI or a lot of belly fat, this ab belt isn't going to magically melt the fat away. You will still need to diet and exercise. However, if you have moderate belly fat you can use the belt to replace crunches and continue a healthy diet and exercise routine.

Gabriella, your BMI is within normal range. BMI does not take muscle weight into account, changes in proportion, and other factors. I weigh 180 and have an athletic build. My BMI is 28.2 according to this website: Many professional bodybuilders have BMI's over 40 because muscle weighs a lot more. See a nutritionist or dietician if it is truly a concern - They will be able to give a clearer representation of your "BMI", what % of fat someone has, and other suggestions for meeting goals or staying fit. Just a suggestion, hope this helped.

I have been using it for about one month and I have seen good results. I do experience headaches and dizziness...if they don't go away, I will have to send it back.

Is it ok to use more than once a day

I got my slendertone last Saturday and I haven't saw results yet. Would it do damage if I use it more than once a day

Sells on eBay for 35 bucks.

Just got my belt today. I workout like 6 days a week sometimes 2-3 times a day, and I have pretty great abs already, but I want perfection. I'm not sure if it is smart that I'm on my 5th session today, but it feels really good! This seems like the perfect tool to look great while i just sit back and do my homework!

@Anna- I have the same question. I don't feel anything the next day, did you ever get an answer? Thanks!

Ive been using it for 2 weeks it works ive noticed my midsection is toner. This will prob not give you a 6 pack. and its not going to burn fat, you still need to do cardio and eat right if you have a flaby belly. but it will tone the muscles.

I ordered it only 3 days ago and while i do feel like some results are already being seen, i am getting major migraines from it and it actually made my boyfriend puke after using it 2 times plus he has the same migraines that i am experiencing. I dont know why this is but if anyone else is experiencing them this could be the reason.

I got mine in the mail seems fairly ok but, I just learned about the slendertone brand so i'm slighlty suspicious of this company now. on the website if you zoom in their belt says flex belt mine says slendertone. It just seems odd that they wouldn't mention they are slendertone.

I purchased my belt last friday since i heard so many good comments about it , so I thought to myself might as well try it - so far so good, but still time will tell for sure.

I expected to feel the same kind of pain the day after using the abdominal belt as I usually did from doing manual sit ups. But this is not the case unless I have it set up in the 60's. Is this ok? My friend who also uses the belt said that one is not meant to feel the same pain as doing manual sit ups, that the belt uses a different method to tone in comparison to doing manual excercises? I'm confused, I would think "pain is gain" even if youre taking the lazy route! So my question is: Is it good / ok to "feel" the work out the next day after using the belt? Does this mean youre getting more of a work out than not feeling anything?
