Bests & Worsts Reviews from Amazon

I have been using this belt system and yes you can feel the squeezing / tightening effects on your abs. They use this electric pulse therapy in some fashion in rehab programs to fix muscle deficiencies. So it is a proven method. The thing is this. It is working on the abs UNDERNEATH your overlaying fat pad. It does nothing to get rid of an excess layer of fat obscuring those muscles worked on. So you use this in conjunction with a weight loss, fat burning workout to actually see the results. But if you choose to keep the extra fat layer over those muscles you will still have the benefits of an improved core for your everyday tasks. For instance the tighter / toned muscles may help those with back problems. To get the flex belt to actually work to do its job you do have to get the settings up to where you don't exactly feel comfortable. You need to feel more than just a tingling from the pulses, but the actual contractions upon you stomach. You need to really feel the squeezing. For me that was at least a setting of 80. But if you are new to this, don't do that. Start with just the tingling levels for you and build up to the squeezing part, otherwise the full sensation will feel too disturbing at the beginning. If after usage for a time, the belt function doesn't act normally to the higher settings and the connection between the remote and belt seem fine, then it is probably the gel pads which need replacing. For like if you see the belt emitting too frequent 'on and off' pulses. I think some of the negative reviews for that it doesn't work are from clearly overweight people who expect the belt to take care of the fat problem too. After this usage just push a finger onto through the stomach area to feel it harder than before. Finally this belt system may serve to motivate one to watch diet and undertake another exercise program to bring those toned abs into view. When I lost a bunch of weight with other exercise efforts after first toning with the flex belt for some time, wow I then saw the nice abs, previously hidden underneath. Hope this helps.
