In the past few years, celebrities and models have embraced Pilates, a method that strengthens and tones muscles, improves posture, provides greater flexibility and balance, and creates a more streamlined body shape. Brooke Siler, Pilates guru and owner of re:Ab, provides one-on-one training of the method through visual imaging and motivation. It's an individualized lesson in creating balance for a leaner, more conditioned body. Her comfortable studio also offers semi-private and group classes for the more experienced. Her new book, The Pilates Body, allows you to practice between visits to the studio. After just one session, you truly feel a difference, walking a bit taller and feeling a bit stronger.
