I used to have one years ago, they're kind of weird feeling, kind of like a tens machine if you've ever used one of those. Personally I didnt get any benefit out of it cos there was too much fat over the muscles to see any difference so I gave it to my brother and he did get a nice flat stomach from using it but if you stop using it you lose the benefit.
Hi Chelly, I just saw this thread, and couldn't resist resurrecting it to say that I have a Slendertone belt, but I am too lazy to put it on! How bad is that? I have never used it for long enough to see results. You've made me think it would be a good idea to dig it out again.
