At this point I am really excited about the Cellerciser. It’s so easy and it’s fun. Reminds me of when I use to jump on the bed when I was a kid (but I don’t get in trouble for Cellercising). I am also wanting to show my mom who is 70 and has weak ankles and is overweight and that combination doesn’t work really well. I think she could do the Health Bounce without a problem. I have two older brothers who are enough time to go running they could Cellerciser instead. Still hard to believe the 10 minutes a day has the kind of results in your tape. I will be in touch in a couple of months to let you know how things are going. GREAT PRODUCT!!!!
