For what I am paying, this gym is by far the best deal in the Shadyside/Point Breeze area. It's quite modern, quite huge, and has pretty much everything you need. I've come here during peak times as well as my typical 5AM workout slot and I've never had a problem finding a machine or hitting up free weights. I have found the staff to be friendly, and overall the place is clean. The fact that there is free 3 hour parking that is close and convenient to the gym makes it even better, especially compared to other gyms in the area like Shadyside X. If you come here with the thought that this is a place where I can workout, with no additional expectations, then you won't be disappointed.
There are a couple of draw-backs to this gym and it may not be a big deal for you depending on what you're looking for. First, it's huge. I think for some this might be a negative since it's a big harder to achieve a sense of community in such a large, corporate like environment. Maybe you don't care? If so, then great. Second, the locker room (at least the guy's locker room), is slightly on the stinky side. I think people need to do a better job cleaning up after themselves. Third, their dumbbells are rounded instead of hexoganal edged. This kind of pisses me off because it makes it impossible to do exercises like T pushups. I'm being kind of picky, but thought I'd at least mention it.
Nevertheless, this place has pretty much everything you need and a lot of things you don't need (cardio theater, really?). If you can snag a good employee discount like I did (gracias UPMC), then it's a fantastic value.
