The Rotational Disks can add variety and challenge to mat workouts at any level. Used alone or in pairs, they are perfect for testing balance and stability. Exercises will be performed supine, prone, standing, and kneeling as well as on hands and knees, isolating movement to upper or lower torso. The highly moveable disks create instability, challenging unilateral and bilateral stabilization to resist undesirable movements and can also be used to allow greater ranges of rotation or lateral flexion through the spine.
