Never realized how unbalanced my shoulders were did this test and realized quickly...
Thumbs straight forward, ribcage anchored, arms up overhead in pure flexion as far as you can go.
after the mob they were about equal and the ROM was much improved...this one is definitely a keeper.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
