Do you have pain in the front of your shoulder after doing curls for the girls!? If so, it’s likely that you have bicep tendonitis. The bicep is made up of two attachment sites, one short and one long. The longer tendon is the most common sight for tendonitis. When the shoulder is not sitting in the right position, it puts extra stress on the tendon causing irritation. By doing the exercise shown in this video you’ll strengthen the muscles on the backside of the shoulder (external rotators), which will pull your shoulder into a better position and relieve the tendon from irritation.
