Can someone suggest a cardio program that is easy on the knees? I lifted weights for years (I'm 54) and I think jogging and leg presses finally took it toll on my knees. My BF% is way up around 42% now and I need the cardio to lose it. Sometimes it hurts just to go steps. I thought of walking and spin class. Also,does spin burn fat or is it more cardiovascular? Thanks.
