I have been taking Zumba and other fitness classes at M Dance and Fitness since February and I still get excited to go. If you want a fun, energetic workout this is the place to go. There are 3 great locations too. Two in midtown, one on the UWS. All the spaces are clean, bright and easy to get to. The music is always good and the instructors switch it up just enough. No one is going to call you out if you miss a move but they will make sure you are not doing anything to hurt yourself. Misty and Diana are two of the nicest fitness instructors I have ever met. Plus, the amount of personal attention they give you can't be beat. Both are so prompt at returning e-mails and will always answer questions before or after class. Misty's prices are really affordable (trust me, I am a poor graduate student) and she ALWAYS is running a fabulous special...!
Go, go go!! You are guaranteed a good sweat and a lot of fun!!
