My kids started gymnastics classes here this summer and love it. The coaches are active in the classes and try to help each kid improve. The place is huge with lots of trampolines, bars, and beams for practicing, plus huge spring floor areas. Pretty much the whole floor is either covered in a spring floor, trampoline, or mats.
We love that they have an open gym for little kids weekday mornings from 10:30-12. It's a great place to go to get energy out--rain or shine.
My only complaint is that they don't seem to clean the bathrooms very often. After being used by lots of kids, they need scrubbed and disinfected daily.
