Hey there,
I was told by my rheumatologist that cycling is good for my creaky knees. I have a treadmill that's doing my knees no good but don't want to get out on a bike in the city. I already walk in the park for a couple of miles every day.
Does anyone know of a good make of exercise bike or crosstrainer that I could use at home as I'm too shy for the gym or the pool?
Are there any other exercises easy on the knees?
