7. Leverage
One can use the mass of the body (or part of it) as strength to perform an action by pressure, pull or twist. However, the ideal would be to make use of leverage to reduce the effort. A point of support must be found, which allows strength to be multiplied during the execution of a submission, sweep, throw or takedown. The body can also be used as a lever in stand-up fighting. The rotation of the torso in Boxing allows a greater efficiency and potency of the punches.
Principles of Leverage:
“Leverage is the act of using a small amount of effort to move a large load”.
A lever has three components:
Fulcrum: The point at which the lever pivots;
Load: The force applied by the lever system;
Effort: The force applied by the user of the lever system
