I'm laughing so hard at the 2 star reviews. Slippery floors never have I experienced it. I do Crossfit and Zumba . The Zumba has kept my cardio- I love it and it adds the variety I need. the building is old but am I going because of the building ?.... NO. I'm going for the work out and the instructors. Do I want a slow Zumba class where the instructor stops and breaks down every step....No. I Want an upbeat class with music that will make me sweat and burn calories. When I first went I didn't know any of the moves but a month into it , I have the moves and still some too work on. Do I go to my work out to talk with people and get upset because some of them don't speak English.....NO. I go to work out. I love the work out , I'm sore , I sweat, it's hot, it's hot, I'm working out with woman who speak different languages and does it bother me... no. Does it bother me it's Latin music... NO it's ZUMBA. If Zumba played honkey tonk music would I be upset ?.... NO it just better be upbeat and fast! I'm still laughing at those reviews. I'm not locked into a member ship I pay for 20 classes at a time , it's just easier because of my work, Crossfit schedule.
