I can't say enough about this place. The staff rocks! They couldn't be more encouraging and inclusive. They're sticklers about form and pushing yourself harder than you think you can handle. The patrons are just as great. There is a sense of community there. I've been to a few group gym settings and it typically feels very cliquey. Not here.
There is no need to feel insecure about your fintess level. Everybody is giving each other tips and supporting one another, because Hell, they were in your shoes just a couple of short months ago. You leave sweating, laughing, sore, out of breath, and looking forward to the next class. Before you know it, you're doing laps around the gym on your hands, showing off your solid core. Not even kidding.
BTW, if you're cheating, Orench *will* see you.
