Before Pilates, those looking to tighten their core were forced to exercise at six times normal gravity inside high-speed centrifuges, hoping the excessive speed would simply fling the flab off. Strengthen your body in elegant, non-centripetal fashion with today's Groupon: for $40, you’ll get two weeks of unlimited mat Pilates or Beach Body Bootcamp classes at Power Pilates (a $144 value), whose Chelsea and Midtown flagship locations tone and flex students into unstoppably bendy Pilarriors. You may also take a single Indo-Row class with today's Groupon.

Power Pilates uses all of the 500 movements of Pilates to flexibilify rigid bodies and sculpt them like an artist using an ice cream scoop on a snowman. Hit the cushy deck for stretch-based mat classes that improve your posture, or try Beach Body Bootcamp, which punches up a Pilates power pack with the cardio benefits for which your cardiovascular system lusts. You may also opt to try one of Power Pilates's new Indo-Row rowing machine classes. To find classes, check the class schedule at your preferred location: Chelsea or Midtown.

Every Power Pilates instructor must first go through a rigorous certification process, so you can expect consistent standards and instruction across classes, unlike the experience you’ll get from instructors who play hooky by scrawling the word Pilates on a scarecrow and mounting it on an oscillating fan.

This Groupon is valid for new clients or clients who have not attended Power Pilates for the past year.

• I used to workout with videos at home on my own. After working out at Power Pilates I found the workout was a whole new experience. I receive individual attention even when in a group class. A Power Pilates workout utilizes both mind and body. I am actively thinking about each movement and leave with a clear head. My body feels good and I leave wanting more. – steph.fox, Google Maps
