Now that I've been around a bit to different locations, I think I can review this one. Green Valley doesn't seem too busy most of the time, and the machines are pretty spread out compared to one particular different location that I visited. There's a good variety of machines with adjustable weights, machines with loadable weights, machines with cords, and free weights. The "treadwall" (rock climbing) machine is also pretty fun to try sometimes even though I suck.
My only issue is that they only play rock music on the intercom at some times, and at other times it's a bunch of "energy" remixes of pop stuff or whatever. I get pumped up a lot more when I get the former than the latter. And yeah, I'm too lazy to get a personal music player setup going. Oh well.
