Gyms have their origins in ancient Greece, where stationary chariots offered stationary horses multiple incline settings to achieve their fitness goals. Get classical fitness and modern finesse with today's Groupon: for $39, you get a one-month gym membership at Crunch (a $135 value). This membership can be used at 10 locations around Manhattan and Brooklyn. This deal is not valid for personal training, Pilates Reformer sessions, or any other fee-based amenity.

Crunch finds the fun in fitness with its non-judgmental, open-minded approach to exercise. With a one-month membership, clients get unlimited access to the gym and its fine facilities. Tap into the timeless power of ancient lever, pulley, and treadmill technologies to tone muscles and trim mass, or exert dominance over weak-willed weights with prop-assisted lifts and lunges. The one-month membership also grants users admittance to Crunch's collection of wildly imaginative classes, split into three categories—Action Sports, Chill Outs, and Dance Rhythms. Strap on a pair of Kangoo Jumps for the BOING with Kangoo class, wrap yourself in the folds of fitness-friendly fabric for AntiGravity Yoga Wings, or peel off skirts of stress in Crunch's pole-dancing class. Crunch even scores clients' sweat-inducing sessions with live DJs.

As a bonus, Crunch is offering a special $29.99 enrollment fee (normally $249.99) to Groupon purchasers who wish to continue with the gym after this deal. Awaken your health from its hamburger-scented hibernation and enjoy a creative approach to conditioning with Crunch.

New clients only.
