I go to Bally's and its the worst freakin gym ever. I'm stuck with a contract with them so I'm forced to work out there. The equipment is always broken and they don't have enough free weights/machines/treadmills. And at any given time of the day, there's endless amounts of schmoes that will just openly stare at you while your working out. It is also dirty as hell.
My friend bought me in as a guest to his gym L.A. Fitness and that gym was amazing. A lot of machines, weights,etc. Great drink stand. And really clean.
