along with

-around the world pull ups.

hang on a pull up bar, then do a circular motion around the bar your neck should be even with the bar at the highest point, do 5 each way, clockwise then counter. or vise versa w/e w/e

-hood Jesus pull-ups. (NOT FOR THE UN-FLEXIBLE) can cause shoulder problems

do an extremely wide pull up but when you go up make sure the bar goes behind your head, and it should touch your shoulders at the peak

-hanging push-ups (NOT FOR THE UN-FLEXIBLE) can cause shoulder problems

these are not easy, do a regular pull up, but stop halfway up. your elbow should be at a 90 degree angle. the top of your head should be about even with the bar. now keeping your body fully rigid, move in towards the bar as if doing a "hanging" push up. its a burner and if it hurts at all STOP.

those are my top 3 fav. pull ups
