I named this move after J.C's favorite Q.B. This is one of my favorite explosive full body exercises. I just started using them in my program, and really love that it requires a powerful drive from the legs and shoulders and a strong core to do these. Also it really shows you your right/left strength imbalances. To do these grab the bar and get down in your best Tebow pose and drive your leg into the ground and punch the weight to the sky. Start light and work your way up. I'm using the bar and 75# and it's pretty heavy for me. For more of a core challenge, drive with opposite foot from the working arm.
