Scratching one's nuts whenever you want to is straight up alpha.

Itchy balls are a sign of weakness and imperfection, much like having a zit. A Trainer needs to create the aura that he's above common afflictions.
That said, I too will defer to AJ.

Allow me to demonstrate:
Ah, not an exercise choice I would do but if it works, it works. 46 isn't old. He's just fine. After all, he's going into a ring getting slammed, thrown around and what not. lol
You don't know what the fuck you're talking about! Where did you get your Certification, Walmart?
