Hold each end of a long resistance band in your hands. Place both feet onto the middle of a resistance band and stand with them just wider than shoulder width apart. Stand tall, brace your core and avoid arching your back. Your arms should be by your sides with your palms facing in. This is your start position. Brace your core, keep a neutral spine and look straight ahead as you extend your left arm out to your side and guide the resistance band up. Be sure to maintain a slight bend in your elbows at all times. Exhale as you do so. Your arm should come to parallel with the floor. Pause, then slowly lower your arm back to the start position, inhaling as you do so. Repeat all the required reps on one arm before changing to the other.
