In vaulting, by a spring of the feet, the body is raised, and by
leaning the hands upon a fixed object, it at the same time receives,
in oblique vaulting, a swing which facilitates the action. As the
inclination thus given to the body depends not merely on the feet, but
on the hands, we have the power to guide the body in any direction.
This exercise is conveniently practised on the vaulting bar, which
rests upon two or three posts. It may be performed with or without
running. The beginner may at first be allowed a run of a few paces,
ending in a preparatory spring; and he may afterwards be allowed only a
spring.
