Works great,
I've had one of these before but lost it. Got a new one and I couldn't be more happy. Now after a long day I can strap this belt on and crank up the electricity and get my abs on. I don't really notice any prolonged soreness like I would from a normal workout so I don't think it's really tearing muscle fibers but stimulating muscle fibers is still better than just lounging out. I enjoy turning it all the way up and try to go about my normal cleaning the house or bending over for whatever. To push against the resistance of the flex feels like it might be making a difference. I need to try to work my back with this as well because a strong core cannot exist without a strong back. This doesn't replace gym and healthy foods but it does help keep your body working even when you need to unwind and watch some TV or fold the laundry.
