idk but before i started i never put more then 45s on squat and i started going right after school at 11:15 with a couple buddys and i just kept putting more and more on, i think it might just be cause i used not go with anyone and i never pushed my self as much cause i had it in my mind i didnt have a spot and didnt wanna look like an idiot when i put too much weight on and do something stupid u know... but i know i put 45's and 25's on yesterday and pumpd 5 reps pre easily, so tomorro i think im gonna try to work up to 2 45's but we will see how it goes
