Instructions
Secure the powerband around a low anchor point, such as a pole or stair rail. Facing the anchor point, get in to a high plank position, with your shoulders over wrists and feet at hip-width or wider apart.
Hold the unsecured end of the powerband in one hand with your arm extended overhead. This is your start position. In a controlled motion, pull the power band toward your shoulder, then return to start repeat for the desired number of reps and then repeat on the other side.
Tips
Move further away from the anchor point to increase the resistance.
