Once you're comfortable practicing therapeutics and mobility routines on the gold ball, it's time to 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!
This is the harder-edge ball that we recommend for working the legs, and you can also use this for your back if it's in good shape. We do not recommend this ball for abdominal, chest or sideline work to begin.

 

Note: This ball comes deflated and requires a pump.
