ABSTRACT:
An exercising method which employs the principle of isotonic exercise in conjunction with isometric impact exercise. The exercising method comprises the steps using at least one lever to which the operator applies a rotational force against an adjustable resilient force, such as a spring, selectively opposing the rotation of the lever; suddenly removing the spring from opposing engagement with the lever after a predetermined amount of lever rotation, thereby permitting the lever to be rapidly rotated by the previously applied force; and suddenly stopping the rapidly rotating lever. The method further comprises sequentially repeating the above steps.
