The CanDo Inflatable Saddle Roll is a professional grade peanut shaped stability ball that aids in developing muscles, coordination, and balance. Its unique design makes it easier to control than exercise balls because motion is limited to the forward and backward rotation. The saddle portion of the roll refers to the center cradle in between the two round  shaped balls. You can use the saddle as a seat or against your back as it provides stability, comfort and confidence for every age. Use it during physical therapy, yoga, the gym or individual physical fitness at home. Available in various color-coded sizes. These colorful inflatable molded heavy-duty rolls can support up to 300 pounds. The 32-inch diameter of the Blue Saddle Roll is measured around the largest point of either end.
