I'm 5'10" or so, 160 pounds. Never was too big, but always been pretty strong. Haven't been hitting the weights in forever, although I've always been athletic and excel in really any sport. Not to mention I have black man hops (about a 40" vertical back in high school, probably now around 35" or so). Once I feel like I'm losing a step when playing basketball, baseball/softball, ultimate frisbee, etc, then I'll probably hit the weights again in earnest.
I'd post a (shirtless) pic but I don't want to put GT to shame.
