You mean because Marty took so much meth under a period of time, and when he stopped (and with the change of diet), his metabolism changed so much and the fat overwhelmed him even when boxing in the yard several times a day?
He was great in his Prime.
Yep, he was ripped because of the meth. I only wish I had his physical genetics (without the meth). I imagine he pulled loads of tail with that physique. If he didn't have the brains of a pissant he could have conquered the world!
