Hi Carolyn,
I have just bought a motorised bike. It was fairly cheap, about $120. However, it has speeds of 30, 40 50 and 60 RPM, and Dr Alberts says you need 80 to 90 RPM. He says results show in 8 weeks, but he does not give any idea of how long each day you need the exercise. I only have time to do 10 minutes each day,
I think Gregg raised this one also.
