Oh, wow, what a neat gym. I've never been a member of a "real" gym, just one of those 24-hr places for a while, so it didn't occur to me that they would have a real PT. My understanding is that cables are pretty good, much better than fixed machines. :)

For the squats, you can get quite a ways with bodyweight. I believe in squats, in the way I believe in chocolate. I'm convinced they're the reason I still have a knee.

I hope it helps! Let me know if you find errors or if it is also confuzzling.
