Rubberguard,Lister Guard/Williams,Nog seatbelt position,trouble shooting,along with some basics.
found this guard intresting because at the end he says he's never being hit in the face while fighting mma on his back.
not sure if this is the same guy but this clip says he's 16-1 mma and sherdog has him listed as 0-0
