Various Postures and Actions

turned, yet he also entirely moves his upper body from his position; and by leaving the placement of his left foot, he shifts his entire weight onto the turned or right foot, in order to execute his throw, to transfer all his weight simultaneously back onto the left foot, thereby making his throw more effective and powerful. Now it is easy to understand that since the first requires much less preparation than the second, it will also have much less effect in his action: For as much as the second needs to move more and through a larger line than the first, it can exert that much more force and power than the first; because the power of the throw is inseparable from the size and speed of the preparatory motion. For just as when one wishes to shoot with a bow, the taut string must be pulled back with force, and would in returning, or releasing, send the arrow quickly and far forward; Similarly, the retreat and counter-movement of the entire body and extended arm brings with it much greater force, when each is quickly returned to their previous position: and who does not know that how a slingstone, when looser and more vigorously moved, will propel the loaded stone further ahead. Similarly, all those who wish to make an uncommon and longer leap, usually, by a fast backward run, impress an advancing motion into themselves, so that they may leap further and lighter.
