What is the difference between the 4″ and the 5″ ball?
We offer a couple of different size balls because some people prefer a larger ball and vice versa. This could have to do with the size and weight of the person. However, it’s not the size of the ball that makes the method effective.
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.
