Way to go, Nan Cyclist! Good for you! Since diagnosis 4 years ago, I have tried several times to get going with a biking program, including several weeks last year as a trial on the Theracycle, but have encountered problems. One is I have had increasing difficulty maintaining anything like the required 80 RPM at all, let alone for an hour. Also, the very good stationary bike we already had seems to cause or worsen serious chronic pain in left hip area (sciatica, periformis, S/I joint area). I'd like to try an upright stationary bike to see if it might be an improvement, but expense is an issue. I have a regular bike, but it's beyond my abilities right now on the streets in my hilly area. Any similar pain or other limitations, experiences, recommendations, or thoughts on this?
