First i thought you were gonna post something about training routines and stuf like that.
After i started watching the vid, i told myself: "well, this guy is being more aggressive because he wants to motivate his partners and toughen'em up."
But damn. Especially the guy in a blue tshirt, at 1:30.
I am convinced it was a feud between this guys and the others, some kind of argueing that pissed him off big time.
