Try a Recumbent Bike For A More Comfortable Biking Option

If it weren't for the relaxed inclined back position I couldn't or wouldn't use the bike as much. The pain is just to great. If for you the seat on a stationary bike is uncomfortable, do what I do. Try the recumbent bike. The seat on a recumbent bike is more like a regular chair that is shaped to fit your back.
Even if you are new to biking, recumbent cycling can be a desirable option. It's not as much the seat for me as the way your knees go up and down. This is why I like to use, the recumbent bike, this helps me with my knees. Because I'm not pushing or pulling straight up and down. I don't feel the pain. You don't see these as often, and there not in the Spin classes. I well use the bike when these are taken, then switch over when one frees up. That's why I have my own.
After all, if your work out is pain fee your going to be looking forward to the next one.
