Answer from Tami Racaniello: Hi Sandra, Pilates is a workout designed by Joseph Pilates, incorporating Eastern Philosophy and yoga. Pilates builds core strength, stability and balance. Your core is more than your abs. Your core refers to the muscles in the abdominals and the back, and their ability to support your spine. Pilates is a highly effective way to help you strengthen your abdominals, and reduce back pain. If you are doing it for the first time, look for small groups, private instruction, or share a session with a friend, so the instructor can evaluate your form, to make sure you are getting the most out of your Pilates workout. Done properly, Pilates is very effective, and the difference will be noticed in a very short time! Tami Racaniello www.itstimetogetfit.com
