So here's what I've tried, people can tell me if their good or no good:
Rowing machine
Take weights and hold them out directly to each side for as long as I can.
Take weights and lift raise and lower arms (like flapping wings)
Lift weights directly in front of me, with arm fully extended, one arm at a time.
Hold weights vertically right next to each other at about chest height and rotate shoulders until the weights are seperated and horizontal.
Hold a weight (like a 45lbs round weight) and hold it out with arms horizontal. Lift the weight about your head until arms are vertical.
Take a bar with weights on it, start with it at about waiste height. Lift it right up to your chin.
