I like the focus, the ability to do a well-rounded cardio and strength workout in 1 hour, and the ability to work at your own level. The instructors and office staff are all great, very supportive, friendly, and willing to help. I always feel welcome there and like they are glad to see me.
It's competitive yet everyone is cheering each other on at the same time. I love seeing my heart rate monitor on the screen. It makes me push harder than I normally would just to try to get in the orange. I love how it something different every time you come.
