The smallest in diameter, this set of 2 dense balls offer a more detailed release throughout the body. Originally designed for runners, cyclists and dancers to release their ankles, calves, and knees. The black balls are a powerful tool for bone stimulation and penetrating deep into the joints. Their smaller size releases the more intricate muscle chains and can be angled close to the bone. The black balls are used in the YBR Yoga and Pilates postures and working both sides of the spine simultaneously. Bring these everywhere you travel. Once you know how to use them correctly they become addictive!
WARNING: Do Not Deflate these completely as they can become damaged.
