My hips and legs get extremely tight when I run. I was recently turned on to this product by my personal trainer who told me these foam rollers are great to break up the tightness and allow the muscle to work properly. It's a little painful to use them but they do work and best of all they are cheap. I own and recommend this product.

My roommate is a pilates instructor and turned me onto foam rollers. They are a lifesaver for designers or anyone else who has should back pain from too much time on the computer. Also great for lower back.
