Imagine trying to escape a rear-naked choke underneath those giant arms?

Ultimate Fighting Championship (UFC) hall-of-famer Ken Shamrock has been hitting the gym and clearly banging out a few hundred bicep curls for each set, evidenced by the humongousness that engulfs every frame of this special "how-to" video featuring Seth Petruzelli.

As in "How to knockout Kimbo Slice" at Bellator 138, which is right in "The Silverback's" wheelhouse.

Shammy will try to finish what he started in EliteXC but I'm not sure the bearded brawler needs to worry about the stand-up game, but rather the submission attack of "The World's Most Dangerous Man." Despite his age, the former UFC Superfight Champion is a dangerous grappler with punishing leg locks.

And Kimbo's ground game is ... well, still evolving (lolz).
