I've been having issues with shoulder during HS Wall Runs. I can feel a muscle in my shoulder snap across the bone when my arm reaches near verticle. My shoulder flexibility is very good in all directions as I've been working on it for the past 2 years. I am working on a few excerses to help with some minor mobility issues. I found out today that this problem also effects me while I fully extend during L-sit Pull-ups. Before today this issue was just a nuisance, now it's a full blown problem because it's hindering development in two exercises. The movement that gives me trouble is anything that mimics a behind the head military press...the impingement comes in at near full extension. The more the load the more the irritation. I don't have constant pain, limited movement, etc. Here's what I'd like; help with stretching or strengthening excersises, etc. that will fix the problem. I have strong & flexible shoulders, but I have to tweak something in order to get over this hump.
Thanks everyone!
