Have you ever ridden a stationary bike? I used to ride Aerodyn's. . . I hated it! If I'm going to exercise I need fresh air and not a stuffy, sweaty gym! I know some people are addicted to them, but this is the only kind of stationery I want to slave on! I know it isn't likely to help my abs or thighs, but my mom enjoyed getting this as a Valentine's Day gift!
