The stability ball is a pretty versatile piece of equipment. If you’ve been watching my videos, you’ll see that I use it for quite a few exercises.
The body moves in three planes of motion. First is the sagittal plane, which involves forward and backward movement. For example, walking on a treadmill is a sagittal plane movement. Second is the frontal plane which is side-to-side motion. Third involves the transverse plane, or rotational movement. Most injuries that occur in life do so in the frontal and transverse planes, yet most exercise machines are designed for sagittal movement. Unless you incorporate those movements into your exercise, you’re at greater risk for injury.
