DA in that heavy-bag pic, horrible stance, punch, etc.
Looks like he never trained in boxing or martial arts. 
I doubt he had ever trained for boxing or MMA. That video was so pathetic and he was very proud of it.

Goes to show that having big muscles filled with oil do fuck all in boxing and fighting in general.
He looked like a 12 year old girl flailing at a punch bag for the first time, it was so pathetic, but hey everyone has to start somewhere i guess.
