A couple of you guys brought up height and mentioned Lee Priest and Dave Henry. The gym manager thought about that. He felt like a man should be full-grown, so you would have to be at least the average height for a grown man in your country of origin. I think that's pretty fair.
On the flip side of that, you could have a 200lbs. guy thats like 6'5", does someone like that belong in the "big boys" side of the gym? This idea is gay and a lawsuit waiting to happen, I really doubt your gym manager is dumb enough to consider it. Everyone paying member has the right to use the equipment they want, regardless of how much they lift, as long as they don't monopolize it. If I'm waiting to use something, it really doesn't matter if the guy using it is doing 3 sets with 100 lbs. or 3 sets with 300lbs, the wait is still the same......all things being equal.
