Four easy-to-follow Pilates exercises in less than 5 1/2 minutes. These exercises will require the use of a Stability Ball (also called a Balance Ball and many other names) and a Pilates Mat or Exercise Mat. When buying a mat for Pilates, you’ll want one that offers nice cushioning for your joints, so we recommend at least 1/4″ thickness. You’ll also want a mat that offers a non-slip surface. When choosing a Stability Ball, be sure to select the right size for your height. We also sell both PVC and eco-friendly PVC-free vinyl for you to choose from.
