Im loathe to admit it but I actually agree with nev on this...nothing about those girls jumps out and says "I joose"
my other half doesn't use anything and he'd really be incredibly good at crossfit type stuff....I suspect he's never going to be "big" because of how endurance based he is but hes hard as a rock and cut to the nines
the girls on my lacrosse and polo team in high school were all jacked lil girls because we all constantly did drills of a million different types
and we all were into other sports as well...I did a ton of street ball.
looking at the weight theyre throwing around...its not huge its really the endurance aspect of it thats incredible
also, I don't think it really matters...they look amazing, they can obviously do amazing shit that I know I can't and Im fairly certain I couldn't even with a ton of conditioning
I think people on this board tend to be biased whenever roids comes up...sure when you see an actor who went from nothing to jacked in three months you wonder but even then I'm not totally convinced.
