Surface sideways standing
Surface sideways standing is one of the basic spiral stabilization exercises. Execution: a hand. Equipment: rope. It targets ribs.
Starting position: Stand with your hip facing the rope handle, your feet are parallel. Your near arm works with the rope (i.e., if your left hip faces the rope handle, your left arm exercises, and vice versa).
Bend your arm with the rope at the elbow and raise it in front of your chest to shoulder level. Keep the forearm horizontal and the palm down.
