The WePlay® Tai Chi Loop Ball is inspired by the traditional Oriental Tai-Chi exercise which involves twisting and turning one's body and encourages hand-eye coordination. The innovative "ball-in-ball" design brings unique visual effect and interesting challenge. When playing with this Tai Chi Loop Ball the wrists, hands and body move rhythmically, just like doing Tai Chi exercise. This unique Tai Chi Loop Ball exercise encourages hand-eye coordination, strengthens flexibility of wrists, and promotes good writing posture. The WePlay® Tai Chi Loop Ball also improves balance in movement and promotes self-confidence by enhancing the ability of reaction and concentration.
