Free Fitness Classes in NYC

Before buying a new car, it's customary to take a free test drive.

But before jumping into a new workout regimen, we often have to plunk down cash to cover membership fees, personal trainer costs and a fresh pair of sweat-wicking Underoos long before we've tried 'em.

Good thing The Hudson River Park Trust is offering a bevy of free fitness classes this summer.

Yoga, boot camps, martial arts, dance, strength conditioning, aerobics core training and even boxing is on offer.

Dubbed the Summer of Fitness (we prefer our summer of Double Stuff Oreos, but each his own!), the program has two parts. The first — on Tuesdays — is a partnership between Lole and FITist and is designed for novices.

Program two tears up Thursdays courtesy of Shape Up NYC. This second set features intense workouts for fitness freaks.

So take a workout for a spin, what have you got to lose other than a few pounds (or your Underoos)?

Tuesdays on Pier 25; Map; Starting June 5; RSVP; Thursdays on Pier 46; Map; Starting June 7; First come first serve
