B.J. Penn is eight days away from headlining UFC 137 live on pay-per-view from the Mandalay Bay Events Center in Las Vegas.
Penn faces former Strikeforce champion Nick Diaz in a bout that places the winner one step closer towards the welterweight championship.
In preparation for Diaz, Penn has split time training between the VA Sport Center in California and his home in Hilo, Hawaii.
Penn reunited with famed boxing trainer Jason Parillo along with training partners Brandon Thatch and Joel Tudor, who are featured in the RVCA video.
