@johnbishop The less expensive bike would be doable, but in the thousands---wow; too much for me. For now, I'm going to have to stay with my tread, stairs, and tapes. We had a pool in every house we lived in except the one we own now. Too bad because I could use one for pool exercises. I think they would be really beneficial, but I don't get in public pools. It's just a germ thing I have about public places.
