Been there once. Way better than old location. Good set of free weights & machines, about 4-5 treadmills, and an elliptical. There is a sign on the door that stipulates hours, but the only restirction I recall is on drill weekend.
The fedex gym in the gucci bldg has more aerobic equipment, but the ang has a better free weight set up. for $5 a visit you get a clean towel and a loaner lock for the locker at the fdx gym.
Only one or two showers at ang, bring your own towel as far as I could tell.
