His way of showing off is probably the best I've seen out of many, he's truly made for this.
However, I think he has maxed out his muscle building potential for a while now, hasn't he? He's definitely bigger than 3 years ago but no difference for a year now. I don't know if he wants to get bigger (I would), but if he does, he must introduce new themes to the game. If he does and continues, fast forward 4 years and he will be an absolute unit just when he is about to reach his 30s and the corresponding muscle maturity of that age. He will be THE man.
