The anatomical location of the human center of gravity varies depending on the individual's posture and body composition, but it generally falls between the second sacral vertebra (S2) and the first coccygeal vertebra (Co1), which are located at the base of the spine. This point is approximately two-thirds of the way down the body from the top of the head.

When a person is standing upright, the center of gravity is located just in front of the sacrum, near the hip joints. This is because the weight of the upper body is balanced by the weight of the lower body, and the center of gravity is the point at which these forces are equal.

When a person bends over, the center of gravity moves forward, and when a person leans back, the center of gravity moves backward. This is because the center of gravity is always located at the point where the weight of the body is evenly distributed.

The position of the center of gravity is important for balance and coordination. If the center of gravity is too far forward, a person may fall forward, and if the center of gravity is too far back, a person may fall backward. By keeping the center of gravity in a central position, a person can maintain their balance and move smoothly and efficiently.
