Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A method for exercising the limbs of the body employing the principle of isotonic exercise combined with the principle of isometric impact exercise, the method comprising: continuously applying a force to a lever with the limb of the body to be exercised and operating said lever in a selected direction against a force resisting means for applying a force resisting the movement of said lever; changing the amount of resistance of said force resisting means during the uninterrupted operation of said lever in said selected direction so as to permit said lever as a result of said applied force to travel more rapidly in said selected direction; impeding the travel of the rapidly travelling lever with a travel restricting means for restricting futher travel of said lever; and sequentially repeating the above steps.
Claim 2
Independent Claim
133 words
A method for exercising the limbs of the body employing the principle of isotonic exercise combined with the principle of isometric impact exercise, the method comprising: continuously applying a force to a lever with the limb of the body to be exercised and operating said lever in a selected direction against a force resisting means for applying a force resisting the movement of said lever; changing the amount of resistance of said force resisting means during the uninterrupted operation of said lever in said selected direction so as to permit said lever as a result of said applied force to travel more rapidly in said selected direction; impeding the travel of the rapidly travelling lever with a travel restricting means for restricting futher travel of said lever; and sequentially repeating the above steps.
Claim 3
Dependent Claim
26 words
A method as claimed in claim 1 wherein said force resisting means is adjustable and further including initially adjusting the force of said force resisting means.
Claim 4
Dependent Claim
24 words
A method as claimed in claim 2 wherein said lever is released from said force resisting means after a predetermined amount of lever travel.
Claim 5
Dependent Claim
64 words
A method as claimed in claim 1 wherein said method further comprises simultaneously applying a force to two levers with two limbs of the body to be exercised and simultaneously operating each said lever against force resisting means, releasing each said lever from said force resisting means, impeding the travel of the travelling levers with travel restricting means and sequentially repeating the above steps.
Claim 6
Dependent Claim
43 words
A method as claimed in claim 1 wherein said changing step comprises removing said force resisting means from resisting the travel of said lever in said selected direction so as to permit said lever to travel rapidly unimpeded by said force resisting means.
Claim 7
Dependent Claim
25 words
A method as claimed in claim 5 wherein said impeding step comprises stopping the travel of said rapidly travelling lever with said travel restricting means.
Claim 8
Dependent Claim
31 words
A method as claimed in claim 6 wherein said removing step comprises removing said force resisting means from resisting the travel of said lever after a predetermined amount of lever travel.
Claim 9
Dependent Claim
26 words
A method as claimed in claim 5 wherein said force resisting means is adjustable and further including initially adjusting the force of said force resisting means.
Claim 10
Dependent Claim
19 words
A method as claimed in claim 1 wherein said impeding step comprises stopping the travel of said travelling lever.
Claim 11
Dependent Claim
23 words
A method as claimed in claim 1 wherein said changing step comprises automatically changing the amount of resistance of said force resisting means.
