VIDEO: Anderson Silva punishes pads during training

Anderson Silva, possibly the greatest mixed martial artist of all time, looks primed to uncork a barrage of knees and elbows on Nick Diaz in their upcoming bout at UFC 183 on Jan. 31. 

Silva, who hasn't stepped foot inside the Octagon since he horrifically broke his leg against Chis Weidman in December of 2013, held the UFC Middleweight strap from 2007-2013.
