Elbow Flexor Stretch
Arm, Wrist, and Hand Stretches:
Stand in a doorway. While keeping the arm straight, raise the left arm to shoulder level. Place the arm and palm against the wall with the thumb pointing up. Rotate the trunk backward toward the wall.
Affected Body Part:Most-stretched muscles
: Left brachialis, left brachioradialis, left biceps brachii. Lesser-stretched muscles:
Left supinator, left pronator teres, left flexor carpi radialis, left flexor carpi ulnaris, left palmaris longus.
This stretch is easier to do by grasping a solidly fixed vertical pole. A tight grasp, however, virtually eliminates the stretch effect on the lesser-stretched muscles. Also, it is more difficult to keep the elbow straight, and a straight elbow is necessary for this stretch to be effective. Although it is preferable to lift the arm to shoulder level, the stretch will be effective at whatever height the arm is raised.
