Hot Pilates is a training system which combines pilates principles with high intensity interval training. It is designed to strengthen muscles, increase flexibilty and improve overall health. The magic of High Intensity Interval Training (HIIT) lies in its ability to keep you burning fat even after you leave the studio. In short, your body isn't able to bring enough oxygen during periods of hard work. Therefore, you accumulate a debt of oxygen that must be repaid post workout in order to get back to normal. The result is your metabolism is still working for hours after you leave the studio.
