The level of inflation of a wobble cushion depends on personal preference and intended use. For sitting or standing exercises, a wobble cushion may be inflated to a point where it provides enough instability to engage core muscles and improve posture. For more dynamic activities such as balance training, a wobble cushion may be inflated less to provide a higher degree of instability. It is important to follow the manufacturer's guidelines for inflation and not overinflate the cushion.
