Just because you cant golf doesn't mean you can't stretch. Try this one called shoulder stretch.
This is a great stretch golfers can use to open up the shoulders and improve range of motion in the shoulder joint. It's a great stretch for any athlete whose sport focuses on the upper body, arms, and shoulders. Golfers should consider this a core stretch in the warm-up prior to a round and repeat as needed throughout the game.
Hold your golf club in front of you with one hand gripping each end of the club with an overhand grip.
