About a year ago I developed osteoarthritis in my hip. I use to walk daily but that became very difficult to do. I didn't want to give up my fitness because I've always been one to stay in shape so I started shopping for a stationary bike that would help maintain muscle strength while not having a hard impact on cartilage. I decided to purchased the Stamina bike because I liked that it was portable and I also liked that it had a gauge telling me how many miles I had biked, the time it took me, and the calories I burned. It also has a resistance knob so I can make my biking more difficult if I want to. After using the bike for almost a year, I am very happy to report that my legs remained toned, and I feel that the bike has actually helped in my arthritis treatment. I use it three to four times a week for about twenty five minutes and I have incereased the resistance on it several times to strength my workouts. This bike is great on those days when I'm a bit off and don't feel like exercising I carry it in front of a TV and bike to a favorite show. The cost was less than $100. and well worth the money spent.
