How powerlifting-friendly is this gym? Enough Olympic-sized barbells and weights available for use? And are deadlifts allowed here? I've heard horror stories about some big chain gyms getting mad at members for dropping weights

Deadlifts are allowed. They have a great section with Olympic sized barbells and weights. You wont be disappointed.

They do have some big barbells and a lot of weights available for deadlifts, but not sure if they'll get mad at you if you drop them too many times, although I've heard some people dropping them when doing deadlifts while I'm there working out.

I was actually disappointed
