Directions
Lying on your left side, put your right knee (at 90 degrees) on your prop (can be anything). Put a good amount of pressure into the prop, while squeezing your hands together (shoulders down not up). release some tension, then roll your shoulder towards the floor, letting the hand flow into this movement. The height of the prop should be determined by your range. If its easy to get your shoulder to the floor, use a smaller prop.
