Shape Up NYC — a city parks department program that’s been running for two decades — offers nearly 100 free fitness classes across all five boroughs, and they’re surprisingly good. Gothamist reporter Caroline Lewis took four classes in four boroughs in three days to put them to the test: Hip House Cardio in Flatbush, Total Body Bootcamp in a Bronx health department basement, SharQui (belly dance) in Washington Heights, and IntenSati (dance-meets-kickboxing-meets-yoga with shouted affirmations) in Forest Park, Queens. She came away sore but impressed. The classes are held in NYC Parks recreation centers and outdoor spaces, taught by instructors who complete a 12-week training program. Some sessions build real communities — regulars at the belly dance class call themselves the Butterfly Sisterhood and do charity events together. There’s no sign-up, no membership, no financial penalty for skipping. Just show up. The schedule is searchable on the NYC Parks Shape Up NYC page. Some neighborhoods have more variety than others (Staten Island gets one Zumba class), but if you’re willing to travel, you can treat it like a free, no-commitment Class Pass.
