Swiss Balls
It seems everyone is using Swiss Balls for rehab and sports performance, but why? The balls activate the “core” and also increase the spinal loading (i.e., not good for rehab). The ball activate the “core” while you are not standing in gravity and only partially dealing with ground reactive forces (i.e., not good for sports performance). The balls are good for a change of pace to stimulate the nervous system and a different workout, but not as the primary workout.
