After not being able to exercise for the past 18 months, my body has gotten out of shape. I am not overweight- at 5'9", 125 pounds, I am thin, but my muscles are just gone! Mostly in my stomach area. I bought one of these, and in just two weeks, I am seeing definition again in my abs! WONDERFUL!!! I have now ordered the arms and bottom toner, as I am still unable to exercise. I was attacked, brutally beaten and raped, and left for dead. This left me with a nasty head trauma that limits me severely so that exercising is out of the question. When I try to get up and exercise, it kills my head. This is a God send! Finally, I can get my body back without killing my head! I watch my diet, and get up as much as I possibly can, but unfortunately, I am pretty much a couch potato, or limited to sitting. I must say, this will NOT take care of fat, it will only tone the muscles that you already have. It is up to you to lose the weight so that you can see the work that it does to your muscles. It is not a MIRACLE worker for goodness sakes, and if you keep stuffing yourself with fatty foods, it WILL NOT work. I restrict my diet to only healthy snacks of popcorn, or fat free yogurt, celery, raw veggies and such. Sugar free hard candies are what I use instead of cookies. My meals consist of fat free chicken or turkey and lots of steamed veggies.
