Start in side plank, supported on your forearm, with an exercise band secured under it. Align your elbow under your shoulder, with your feet together or one foot slightly in front of the other and the body in a straight line. Hold the other end of the band in your upper hand with your arm straightened in front of you.
Keeping your arm straight, pull the band and lift your arm up, pointing directly towards the ceiling. Lower in a controlled manner to near the floor.
