I hate crowded gyms
Hate it when the dbs are all over the floor, (on the floor near the rack is fine by me, but out in the open ? no)
people who try to slam the stacks on the machines, you know let go of the handle to hear the stack fall? thats how most machines break.
hoggers, or those that have a spotter, friend etc. who talk alot before,after, and even during sets, so annoying.
