Michael Bisping Punching Fat Guy's Belly On TV Set Is Hypnotic

There's something about watching UFC legend Michael Bisping punching his hands through a fat guy's doughy belly that's just captivating ...

This little fight session went down on the set of Cinemax series "Warrior" in Cape Town, South Africa -- where Bisping has a role as a smack-talking violent badass (what a stretch, right?)

In this particular scene, Bisping squared up with Kazakhstani stunt man Erden Telemisov -- but when the cameras stopped rolling, the two guys decided to have a little play fight of their own.

Bisping talked trash and then threw a flurry right into Erden's gut -- and watch the blubber fly!!!

Make sure to stick around for the slo-mo zoomed in shot ... which is just as fascinating!
