Hang a rope or suspension straps from a rack or other stable object. Grasp the ends and position yourself in a supine position hanging from the ropes. Your body should be straight with your heels on the ground with your arms fully extended. This will be your starting position.
Begin by flexing the elbow, pulling your chest to your hands. Retract your shoulder blades as you perform the movement.
Pause at the top of the motion, and return yourself to the start position.
