THE LINE OF GRAVITY
a. The line of gravity is an imaginary vertical line that passes through the
center of gravity (figure 1-5). Follow the line of gravity in the profile shot (left half) of
figure 1-6. When erect, the line of gravity passes behind the ear. It continues just
behind the center of the hip joint. Then the line descends along the knee and ankle
joints. (The exact location of the line of gravity will, of course, vary according to
individual differences in body build and the curvature of the spine.)
