You won't like the lifestyles, and its always packed as shit. The bucs cheerleaders do their thing there and everything grinds to a screeching halt with everyone gawking.
The old extreme gym on howard has just been renovated, its called choice now, i think its worth a look, but once again, it depends on your location. They've got boxing and BJJ there too, back warehouse area has no AC and you can pretty much do whatever you need back there.
