Step by step instructions
Stand in a split stance with left foot on center of a resistance band, right foot behind body. Bend both knees slightly. Place wrists inside handles of band with palms facing down and hands to your sides. Keep the handle of band slightly higher than edge of wrists for best support. Pull stomach in and keep shoulders down during the entire movement.
Lift arms out to sides of shoulders and inhale. Bring arms back down to the starting position while you exhale. That's one rep. Complete all reps on one leg. Repeat on the other side.
