Riding a bike is a great way to lose weight, burn calories, and work on cardiovascular fitness.  But sometimes, we buy a bike and ride it for a couple weeks only to leave it in the garage because we can’t get comfortable on it.  After a ride, you may feel saddle soreness, low back pain, or neck and shoulder discomfort.  You may also experience numbness or tingling down into your hands or hot spots on the bottoms of your feet.
