I don't see the need for them to be in there that long. (unless they are doing every exercise known to man)
Some of them are lifting waaay to heavy also. Every time I see them they are always snapping their shit up. I bet their spotter gets a better work out than they do...
They also leave the weights room in a tip you can barely see the floor and the weights room is a little bit smaller than my bedroom.
I always end up putting all the weights back on the racks.
The only good times to go are early in the mornings on the weekend. Then I have the weights room all to my self. Its bliss.
