WORK OUT YOUR ABS

Abdominals are the most important exercise you can do; they improve your posture and prevent back injuries. Work every part of your midsection-upper, lower, and oblique or side muscles--with a series of wonderfully safe and effective exercises, all arranged by fitness level. Guided by instructive anatomical diagrams and close-up photographs that illustrate the proper technique, do movements that improve alignment, aerobic combinations that target the tummy, crunches, sit-ups, leg and lower body lifts, side twists, and many more.
