Waiter sideways standing
Waiter sideways standing is a basic exercise of the spiral stabilization method. It is performed standing 1 arm. Equipment: rope.
Starting position: Stand with your hip facing the rope handle, the feet are parallel, the rope is in front of your body. The far arm works with the rope (i.e., if you stand with your left hip facing the rope handle, your right arm exercises, and vice versa).
Breathing in, straighten up and align your pelvis and lower spine. Move your arm with the rope from the pelvis along the chest until it is up.
The full procedure, a video with voice guidance and what to watch out for are in the Spiralista app.
