really could use a few more functionally postured protective shoulder exercises that do not overly challenge the shoulders tender or worn mm as much. Pushing from door knob a resistive band in each hand from a bent elbow near the side and up a bit similar to a reach foreward or 90 degrees (or 80) and also a pulling version similar to this but starting with elbow extended and bending it as they come back with slight (35-40 degrees) abduction. With pulling letting the elbow be bent as they come back to just past there side. Both of these need to be done in a karate ready style of stance versus leaning back or forward while sometime the band may break and lead to fall. Start thinking 50 to 90 year olds and you can understand why I say all this. Better to use the older person too for the video - thank you.
