Mother always said sit up straight. Truth is, she was right. All that hunching over at your desk from 9 to 5 can do a number on your spinal cord and its surrounding muscles. Thank heaven for this physical therapy feast that includes Feldenkrais and Pilates. Feldenkrais is geared toward re-educating the body for better postural alignment using a hands-on approach, similar to rehab with a practitioner. Pilates, which is all the rage with Hollywood celebs, is a non-aggressive way to strengthen and stretch muscles using resistance and machines. It's all designed to give you that sleek, firm look you want, minus all the sweaty huffing and puffing.
