Stand upright with your feet shoulder-width apart over the middle of a band, with your arms fully extended by your side and each holding one end of the band.
With your palms facing each other, exhale and raise yourself up by standing on your toes while continuing to keep your arms fully extended by your side.
Continue to raise yourself on your toes until you are no longer able to do so.
Inhale and lower yourself down until your feet are firmly planted on the ground, returning to the starting position.
