Wrap a band around a power rack or pole immediately below shoulder-level and stand upright with your arms outstretched in front of you at shoulder-level.
Holding each end of the band with an underhand grip, exhale and bend your arms to curl them in the direction of your shoulders. Do not allow your torso to rotate.
Maintain the position of your upper arms at shoulder-level and continue curling your arms upwards until you are no longer able to do so.
Inhale and allow your arms to extend, returning them to the starting position.
