1. Interval Class at AquaStudio
Spinning is awesome. Swimming is awesome. Why not do both at the same time? Switch up your workout by spinning on a bike submerged in a pool, which can burn up to 800 calories in one class and take your cycling to the next level. The interval classes take place every day of the week in the mornings and evenings at the Tribeca studio. 78 Franklin St (212-966-6784, aquastudiony.com). First time $35, one ride $47, one ride off-peak $39.
