Williamsburg is all about being alternative, even when it comes to a workout—and this massive gym, school, and training facility fits the bill. Quietly warehoused on the neighborhood's rapidly developing south side, most residents aren't even aware of the Trapeze Academy next door. Alt-fitness mogul Elizabeth Streb teamed with Mexican circus brothers Noe and Ivan España in 1998 to create a trapeze arts school for all levels of experience. Training comes in 10-class packages but is also open to drop-ins. It is centrally located between the Bedford L and Marcy Avenue JMZ stations.
