This is the Pilates apparatus that strengthens the muscles around the spine to help correct posture and improve flexibility. Designed by Joseph Pilates, inventor of the eponymous fitness system, the P-shaped device combines a barrel and a step, with a padded top for comfort and side handles that aid balance. Users sit, kneel, lie, or lean on the corrector in innumerable positions that stretch and strengthen the core and limbs. The tool takes pressure off the knees while toning the legs, and its focus on the upper back helps open the lungs to foster deep breathing. Comes with a DVD that demonstrates more than a dozen exercises. Made from wood, with upholstered cover. 27 1/2" L x 17 1/2" W x 13 1/2" H. (29 lbs.)
