Believe it or not, your COG can be located outside your body.How is this possible?

When we define the COG, we do so from the reference of a static, standing position.

But the body is continuously in motion, which means we change positions often.

With each new position comes a new location for the COG.

Even slight changes in position can change where your center of gravity is.

The center of gravity is also called the center of mass.

The two terms are interchangeable.

Lets Get Technical

The COG is the average location in a 3-dimensional space of a bodys mass.

Body mass may be understood as the total amount of physical material that comprises your body.

You might also think of mass as your bodys resistance to movement, a.k.a., its bulk.

(The sacrum is made up of five vertebrae fused together vertically.)

So, with any movement of the ball, this center point moves right along with it.

But, when we consider the center of gravity in the human body, things get more complicated.
