T-shirt training refers to going to the gym with the sole purpose of gettin' buff for da ladiezzzzz. Often performed before a big night out in order to look fresh, a t-shirt training session involves doing bench press, biceps curls and tricep extensions in order to get PUMPED!!!!!!! Although such a routine will leave you with a disproportionate upper body half, this is not an issue as massive 'guns' are DENCHHHHH!!!!
It is a well know fact that if you perform a big t-shirt sesh before a night out, you are 99.99% more likely to get laid.
"Yo playa, you gonna put in a t-shirt training sesh before going out tonight?"
"You know it brother gotta stay fresh for ma bitches. LEAVE IT YEAH!!!"
