Any recommendations for a fitness center or gym in Syosset?

I am a member at Equinox in Woodbury. If you are a gym person, this is a wonderful place. It is super clean and everyone is helpful and lovely. Most of all, there are wonderful classes of all kinds and levels, great trainers if you want to go that route, and ample machines and weights for all. If you go online, you can look at a schedule of classes or go there and someone will be happy to take you on a tour.
