Reaction Force For every force there is an equal and opposite force. For example, when performing a front punch, the other arm pulls sharply towards your hip. (Newton’s Law)

Balance To maintain one’s equilibrium throughout a variety of techniques. To maintain one’s center of gravity low and equally distributed over your feet while keeping your body upright. To remain flexible yet stable.

The five points of power

Focus One must concentrate all of one’s physical and mental energy on one purpose and/or target. One example is using the smallest tool to the most vulnerable target.

Speed Travel time of striking tool to target. Most essential element of power. Without speed none of the other points are useful. In Taekwondo it is crucial to be relaxed both mentally and physically in order to be fast.

Breath Control Exhaling at the moment of impact when striking, blocking, or receiving a blow. The ability to breath, using the lower part of your lungs as well as the upper. With proper breathing one can increase their stamina and add power to techniques. Often a kihap.

The Theory of Power involves five elements. One must employ all five elements of the theory in order to have maximum power in one’s techniques. These interact with each other and depend on each other.

We train to rise above ourselves, Not to rise above other people.
