Fitness instructor Ana Caban leads this innovative workout that focuses the benefits of Pilates on the core muscles group. The challenging circuit tones muscles in the abs, hips, buttocks and lower back, enhancing strength, balance and posture. The two routines (one 20 minutes, the other 40) employ Pilates moves such as the hundreds, single and double leg stretches, roll-up and scissors in fluid succession, making the workout feel more natural.
