I have 9 types of artritis - I recently had both hips replaced. During my physical therapy, I began building ups my leg muscles. I have been trying water therapy, and the age old excuse, finding time and babysitters are hard. ( I have a 9 yr old and a 3 yr old). I want to do something at home - I walk about once a week. Unfortunately, I do have many flare ups and exhaustion is part of my illness, but I want to continue moving and building my muscles up again. I tried step aaerobics in 1990 during a remission and thoroughly enjoyed it, and would like to try again and didn't know if you had a simple low impact program I could follow. Thank you for your time. Cindy
