I have had my system for close to a month now and I must say, it is amazing what technology has come up with. It is great for people at any level of fitness. Somewhere I read that it was tested in nursing homes with great success. It has helped my sore joints and helped me to get off the couch. Any input from anyone that owns one?I got one a couple weeks ago and I really enjoy it, too. On days when I am sore, I can still use yoga to stretch. Other days I can do more. It is entertaining. Only problem is I can't get my kids and hubby off it!!!
