BENT-OVER SIDE RAISE
Connect one end of a resistance band to a D-ring on an ankle strap, and attach a handle to the other end. Do the same for a pair of resistance bands. Keep your leg shoulder width apart and grab handles from the opposite side and cross it between your calf. Bend knees and bend over through hips with back flat close to horizontal. Bend elbows slightly and hold the handles with palms facing inward.
Raise upper arms to sides until elbows are shoulder height. Maintain fixed elbow position (10° to 30° angle) throughout exercise. Slightly rotate wrists anti-clockwise during exercise to facilitate movement. Lower and repeat.
Upper arm should travel in perpendicular path to torso to minimize relatively powerful Latissimus Dorsi involvement.
