The major difference is that the Pilates technique not only has a full complement of matwork, but it incorporates work on the Pilates machines. The emphasis of the exercises is to strengthen the abdominals, improve posture, stabilize and lengthen the spine, improve balance and overall strength. Pilates gives you a longer, leaner, dancer-like line.
Pilates works the whole body, emphasizing control, precision and concentration in both the mind and the body.
