Best time to hit the weight room (lyon center) is anytime before 4pm. till about 9pm its the a-typical bench and curl type (i refrain from saying frat boys but you know what i mean).
Luckily if you train T-Nation style, no one (except me and 2-3 other people) uses the power racks.
Everyone generally will stay out of your way if you have headphones on so utilize those... best bet is that if you plan on using a piece of equipment throw a towel over it.
I might be training downtown at gold's to avoid the crowd and so that I can use chalk.
But PM me and if i'm on campus whenever you want to train we'll see if we can work out some sort of arrangement.
FYI, there is an olympic lifting club on campus. If I have time between MMA, school & work I might join just to find out where they train I'll keep you posted haha
