Please please please open one of these in the Bay Area. SO MUCH FUN.
If it's good enough to tone up those Cirque performers, it's surely good enough for us regular folk.
Definitely not a full service gym, but in one girl's humble opinion, way better than one too. All the classes (minus the dancey ones, obvi) focus on using your own body weight to build strength, which I am a big fan of. Plus, silks climbing classed, AERIAL YOGA, and pole classes. Sold.
