Once you're comfortable practicing all the YBR routines on the gold (was yellow) ball, graduate to this harder, denser ball to get deeper into your tissues. The silver ball lets you work individual muscles in more detail. It offers greater intensity, more profound releases,and a true deep-tissue massage experience. We guarantee you'll really feel your muscles!

*Note that balls come deflated and we recommend purchase of "The Pump" for portability, ease of use, and maximum compatibility. Not all sports pumps work optimally with Yamuna balls. Note: Balls do not come inflated.
