balls

Baoding balls (Chinese: 保定健身球; pinyin: Bǎodìng Jiànshēn Qiú; Wade–Giles: Pao3-ting4 Chien4-sheng1 Ch'iu2) are metal balls small enough to hold in one hand, used for physical exercise and therapy. They are also known as Chinese "balls for ball practice" exercise balls, Chinese health balls, Chinese meditation balls, and Chinese medicine balls. Baoding balls are used by rotating two or more balls repeatedly in the hand. Intended to improve finger dexterity, relax the hand, or aid in the recovery of muscle strength and motor skills after surgery, Baoding balls work similarly to Western stress balls.
