Movement
Side Lying External Rotation Movement
1. Lying on your side on an exercise mat or padded floor, prepare for this exercise by aligning your head, shoulder, hips, and knees. Place your bottom arm under your head, and out at an angle to support your head and body.
2. Holding a very light DB, bend the elbow of the arm that's stacked on top of your body to 90 degrees. Your upper arm should remain in line with your body, with your forearm perpendicular to the body.
3. Keeping your upper arm tight to your body, slowly rotate the forearm away from the center of your body. Stop when you can no longer keep your upper arm in contact with your torso.
4. Slowly return to the start position, always moving with control and intensity, before repeating. This should be a slow, controlled motion. Do not use momentum, or jerk the weight up.
