Greetings,
I am currently training in F1 and HS series (2nd month) and i tried for my warm up some shoulder rotations with a light bar. I have seen a lot of people doing this exercise and their shoulder (?) ROM allow them to twist their shoulders without opening their fists. I can't do that and i am posting this exercise, so if anyone has any tip or can help me discover what it faults so i can improve it would be really awesome!
