External Rotation

Exercise Data
Main Muscle Worked: Shoulders
Other Muscles Worked: None
Equipment: Dumbbell
Mechanics Type: Isolation

Tips: This trains the infraspinatus and teres minor muscles which help keep your shoulders safer from injury. Lay down flat on one side on a flat bench. Using a light dumbbell start the exercise with your right arm fully against the right side with the elbow flexed at a 90 degree angle and pinned against the left hip bone. Do not move your upper arm from this position during the exercise. Slowly raise the dumbbell by rotating the right arm upwards while maintaining your 90 degree bend in the elbow. When your lower arm is pointing straight up, lower it down until it is almost touching the bench. Repeat. Do not move your torso during the exercise.
