secure the band underneath your toes and make sure that the length of the band between the foot and the arms is the same for both sides. While holding the handles of the band, raise your arms to the side of your head as if you were ready to perform a shoulder press. Keeping your hands by your shoulder, stand up on your toes as you exhale and contract the calves at the top of the movement. After a one-second contraction, slowly go back to the starting position.
