UFC announcer Joe Rogan may not be a professional fighter but he certainly trains like one, at least where BJJ is concerned.

In this MMATraining Technique of the Day, Rogan works with Bas Rutten to demonstrate how to take an opponent’s back who has blocked you from moving into full-mount. Then, just for kicks, heavyweight Josh Barnett steps in to reveal the rarely-seen “crawl between an adversary’s legs” set-up to land some offense of his own.
