Sit-ups remain one of the best methods of reshaping the abdomen, second only to standing in front of a lit cannon. Enjoy explosive exercise with today's Groupon: for $79, you get a Pilates package at Pilates MN in Wayzata (a $200 total value). Each sweat-coaxing package includes:

• A Pilates orientation (a $75 value)
• Five Pilates reformer classes (a $125 value)
  
  

The certified and experienced instructors at Pilates MN lead bodies to pipe-cleaner-like flexibility with extensive coursework and individualized guidance. During the one-on-one orientation, students consult with professional trainers to take aim at personal goals and gauge strength with a comprehensive fitness screen and a diagnostic caber toss. Next, a series of five reformer lessons teach pupils the basics of Pilates equipment and unite the mind and body in stretchy harmony with breathing techniques and strength and flexibility exercises. In each 60-minute workout, repeated flexion, extension, and rotation routines build both muscle power and limberness, rendering bodies capable of showing off lean, well-hewn muscles in the most complicated of flexes or Twister matches.
