The feats of Taekwon-Do are great in number. To the layman in the street, such feats may sound impossible, but to the serious students of Taekwon-Do and the exponents of this art, it is quite ordinary. Of course, by mastering this art it does not mean that you will be asked to do acts of impossibility. Particularly if someone should challenge you to kill a wild bull with your bare hands. Therefore it is clear that equivalent demonstrations of such effective use of pure somatic force is not to be seen in other forms of physical combat technique.
Incessant training is essential to keep oneself in top form and physical condition.
In training, all the muscles of the human body will be used. From the use of one's muscles, it will be possible to harness all available power generated by every muscular contraction. It will them be necessary to deliver such power to the human target especially to where the most vulnerable points or vital spots of one's opponent are located, in particular when the opponent is in motion. Most of the devastating maneuvers in Taekwon-Do are based specially on the initial impact of a blow plus the consequential additional force provided by the rebound of the opponents moving part of the body. Similarly by using the attacker's force of momentum, the slightest push is all that is needed to upset his or her equilibrium and to topple him or her.
