This is a great exercise for grip strength, trap and delt development and for static strength. I call them "Kirks" after my friend Kirk Karwoski. Kirk started doing these after his deadlifts to develop his grip strength. Kirk has small hands, and he and his coach Marty Gallagher put these in his training to help him hang on. Obviously it worked as Kirk has deadlifted over 800 pounds. To perform them take a grip right outside your thighs. Pull the bar to your belly button, bending your arms and shrugging at the same time. PAUSE for a 2 second count and repeat. You can cheat slightly to get it started. Kirk also used a thumbless grip on this, which makes it even more difficult.
