$20 for 20-Class Yoga and Fitness Pass from MetaBody ($350 Value). 28 Locations Available.

Like tug-of-war tournaments and harmonized singing telegrams, workouts are more effective when done with a group. Join a fitness community with today’s Groupon: for $20, you get a 20-class fitness pass to MetaBody (a $350 value). Classes can be redeemed at 28 New York City–area locations. MetaBody will donate 10% of its Groupon proceeds to diabetes research.

The inspiring trainers at each MetaBody location lead troops of workouteers in results-oriented workouts several times weekly. Sweat sessions utilize a variety of exercises and disciplines to produce full-body results in a supportive environment, ideal for beginners and hard-core core hardeners alike. During any class, motivational instructors will use the instinctual distrust of routine to their advantage. Begin a day of litigating with a refreshing early-morning boot-camp session, or wind down by burning evidence and pounds with a late-evening yoga class.

Muscles are kept guessing with new and challenging moves during each session, so participants never fall into a boring, ineffective routine, such as regular teeth brushing. In addition to fitness classes, students receive a success guide to help to prepare them for imminent pound loss, a nutrition guide, and a $100 gift certificate for individual coaching. Because the pass sets a 5-class cap at any given location, roving fitness mavens can further shake up their workout regimens by vetting a series of classes or instructors that work best for them.
