I was hooked from the very first time I stepped into Mountain Sky Jazzercise. The music is upbeat and fun, and the aerobics are great. I get a great workout every time I go to class, and I always miss it when I don't. There are people there from ages around 14 to around 80 something...its a great environment for anyone! I am a 20 year old college student and would much rather go to Jazzercise than ride a stationery bike or run on a treadmill. It's always TONS OF FUN!!
