Sternum Pull Ups.

Here's a great variation of the pull up. Start by arching your back so, as you pull yourself to the bar, your sternum touches the bar. Great movement. I have to thank my car for allowing me to reach the rafters, lol. I do them in between the rafters with a parallel grip because if I try to use the beam like a high bar on this movement I crash my head into the beam behind me. Great move though. Here's my 3rd set in a session where I did 8 sets of 8 with only  10 seconds of rest in between sets.
