How:
Sit against a wall, knees at 90 degrees, push your butt into the wall and tuck your neck into your chest. Arms above your head with elbows bent at a 90-degree angle, and hands towards the ceiling with palms facing out. Try to have elbows and back of hand touching the wall, and press your chin to your chest. Slide your arms and hands up the wall.
Purpose:
Shoulder rotation is critical for the early vertical forearm catch. The level of stress on the shoulder is determined by hand position, body rotation, width of catch and pull. But too many protections and compensations can lead to power loss. We need internal rotation to achieve the most dynamic positions and create the most powerful arm angles.
Question:
Can elbows and back of hands touch the wall and be pushed over your head?
