Input:
As a semi professional rock climber, I suffered from lateral and medial epicondylitis. Warming up, and warming down with the Thomas twist, and some variations of that completely got rid of the pain.(it also helped me get rid of shoulder pain) I was skeptical when I saw reviews like this, but had no other options. Very pleased with this miracle of a product! I recommend to anyone suffering from pain in the arms!
