Muscle of the Month: Biceps
Does the Biceps muscle remind you of Popeye? If you eat enough spinach, it will get big:)
The long head of the biceps pulls on the shoulder and the short head pulls on the shoulder blade, and when it is tight it can pull the shoulder forward causing the shoulder bone to slip forward a little, out of alignment. This condition is called "anterior humeral glide syndrome: and can have the side effect of causing impingement and pain in the rotator cuff.
Tight biceps can also cause tennis elbow by straining and pulling the forearm into pronation if it is too tight.
So Stretch those biceps!
