shoulders back / chest out / stomach in /elbows out and back / if you stand by the guy long enough he will either give up and exhale or pass out.
i finally realized the irony in why they do this the other week as we have a guy who trains in our gym (and wears those stupid five finger shoes) that has ILS bad.
He finally relaxed long enough for me to see that he has absolutely no depth to his back whatsoever. Weird. It was like nothing but shoulder blades sticking out. Then he caught me looking so he blew up again.
Bad thing is he's got a good set of chest/delts on him.
But ghey nonetheless.
