Many people would love to use an exercise bike to stay in shape, but they cannot find a good one since they have back problems. This makes riding a traditional bike painful and uncomfortable. As a result, they get out of shape and the back problems get worse. If you have been facing this problem, you should buy a recumbent exercise bike instead. This is a bike that allows you to sit back so that you can relax. The pedals are out in front of you. This gives you exercise along with the back support that you need to have.
