The magic circle was created by Joseph PILATES to be a versatile exercise aid that you can add to your mat class or use by itself. The soft, rubber-covered resistance ring provides faster, more targeted toning, improving muscle strength throughout the body and adding even more awareness about engaging your powerhouse, deepening the workout, & taking it to the next level. The magic circle is lightweight and portable; it can anchor a complete workout of resistance training & be formatted to any of the mat exercises. It will isolate muscles but will also deliver a workout to secondary muscles, like the power house. Adding the magic circle after you have experience with the mat is the best way to go and get the most benefit.
