To all the shoulder experts on here, I was messing around on the scaffold bar at the works last night once my fingers were tired and am wondering:
- Why can I hang 1-armed (but arm must be locked at some sort of bend, even if just off straight) in a leg raise position for quite some time (15-20 seconds) when I am parallel to the bar but when I'm perpendicular to the bar I can barely do 5 seconds with two hands?
I'm guessing there's some massive shoulder instability going on there and I'd like to address it. Can anyone begin to explain why this may be?
Thanks!
