I used to workout at the gym on Pearl, but that was a good fifteen years ago! Back around 91-92. What I remember was it’s large they had lots of equipment. Probably upgraded quite extensively since then.
I was at Ft. Shafter in the late 90’s. I always drove to Hickam or PH to use their gyms. As I remember it PH had ALOT of Hammer Strength and Hcikam had more freeweights.
