I was skeptical, I admit. I hadn't truly had any form of exercise program in 20 years. I started bouncing about an hour total a day, eating for nutrition and not worrying so much bout a diet. I've lost 25 pounds in 12 weeks, toned my body a lot, see inches falling off, sleep better, and my neck and back have not hurt since I started. If I never lose another pound, I will still bounce daily from now on! Worth every penny! I just jog and bounce freestyle ... My body seems to know what to love next naturally. I am addicted, no doubt.
