1. For the German Arm Swings- Should I tolerate any shoulder clicking when doing the movement?
If the answer is no, should I restrict the range of movement to click free and focus on the swings or do something else? What I've been doing is to just do frequent lat leans and stretching and test for progress with the swings. I think I see progress. The stretch I use is to kneel, sit back onto my ankles and slide my palms out along the floor in front of me...sort of a "kneeling prayer" sort of position. I can do something like cat/cow in that position (just upper spine) or lean side to side and it really gets the lats.
2. Lat lean- the video shows gripping a horizontal bar. Can I use a door frame?
The difference is changing the hand from pronated if I grip the horizontal bar to neutral if I grip the door frame. I hope the door frame is okay because there are lots of them and it lets me do the exercise frequently.
My shoulders are a mess. Poor range. Weak. Winged scaps. I wonder if I should be doing some bands and foam roller or something to supplement.
