"  Pilates, an exercise system that focuses on the core postural muscles, is not only a full-body toning routine that improves flexibility and strength\u2014it&amp;#039;s a system of exercise that teaches awareness of breath and alignment of the spine. It can be practiced in conjunction with an intensive cardio routine (such as running or swimming); or, when the moves are performed in a series, it can act as a complete cardiovascular workout of its own.
