Need an extra set of balls?
Depending on a person’s size, condition, or simply preference, the 5 inch ball may provide support that helps you feel the weight of a particular part of your body, rest more easily on the ball or with more certainty.
One 5 inch ball can be great for under the knee, and two 5 inch balls feel great under the hips.
You can also adjust the air in the 5 inch balls with a standard bicycle pump. (See the pump picture)
