The Fitness Mad Studio Pro Pilates ring is a professional training aid based on the original Magic Circle design. It helps target specific muscles and thus makes toning faster. The ring is a great way to challenge inner and outer thighs, upper arms, the chest and even the pelvic muscles. This smaller version of the ring has a 12″ (30.5cm) diameter and offers a greater resistance when compared to a bigger 14″ model. It has a sturdy tri band sprung steel construction that can easily withstand a very intensive studio use and is fitted with convenient to use soft TPE double handles.
