of the guys who haven't posted pictures? hm.
pumpster - i'd say he's probably early 20s and not that big, but in good enough shape so in a tank you can tell he works out in some capacity. but because he works out at home he has no idea how unimpressive he is compared to your average lifter.
man of steel - i'd peg him late 20s if not a little older, average height. not that lean, but thick. the kinda guy who walks into a gym and just looks like he's going to be using most of the 45s.
db2431 - doesn't work out, for the most part. might do some bodyweight exercises, the kinda guy who buys those stupid little handles you see in magazines to do pushups off of. found getbig almost completely by accident.
count grishnackh - looks suspiciously like the heckler.
the heckler - looks suspiciously like adonis.
adonis - looks suspiciously like a shit squeezed out by a child with an especially tight asshole.
i'll come up with more, but i have to head to the gym. they close early on saturdays and it's drinkin' night.
