Suppose that the strength of a person is represented in units. Assume further that a person standing in front of me has 10 units of strength to my 7 units. Now, if he pushes with all of his force I shall certainly be pushed back or thrown down, even if I use all my strength against his. But if, instead of opposing him, I were to give way to his strength by withdrawing one’s body just as much as he had pushed, taking care at the same time to keep one’s balance, then he would naturally lean forward and thus lose his balance.
Because of his awkward position, his strength for the moment is only three units instead of ten. Meanwhile, because I have maintained my balance, I retain all seven units of strength, and therefore can defeat my opponent by using only half my strength original seven units of strength. This is a simple example of how, by giving way, a small contestant may defeat a bigger, stronger opponent.
