Wrap a band around a power rack or pole 1-2 feet above head level and stand upright.
Grab each end of the band with your arms bent perpendicularly at shoulder-level using an overhand grip.
With a staggered stance, exhale and press both arms forward, downward, and inward to extend them while simultaneously bringing them closer to the middle of your body.
Continue until your arms are fully extended. Do not allow your torso or legs to assist with the movement.
Inhale and allow your arms to raise and bend, returning to the starting position.
