In practical terms releasing power can only be effective if the person applying a technique can combine the ability to generate a great amount of force with doing so in a short time. Skill, in terms of delivering a technique accurately, and the capacity to harness the maximum possible strength possessed by an individual also have a great bearing on whether it “works” or not.
Taijiquan requires us to “focus power onto a single point.” At the same time it makes use of a type of sequential movement that picks up strength through the kinetic chain of every action. This is reflected in the saying that every practitioner is familiar with: “Power starts from the feet, goes through the legs, is directed by the waist and expressed by the hands.” In the excitement of trying to replicate the fajin effect of a skilled exponent it’s easy to lose sight of what is behind their action that makes it so powerful. It’s all too common to see people trying to muscle out the movement with their upper body and overlooking this sequential chain effect. Outside the realm of Taijiquan a study by Russian Yuri Verkhoshansky, a prominent figure in the field of explosive strength training, examined boxers of varying skill levels trying to establish where their power came from. He found that elite boxers generated 38.46 percent of their force from their legs against only 16.51 percent by what he described as Class II and Class III (lower level) athletes. At the same time superior performers relied less upon trunk rotation (37.42% vs 45.5%) and arm extension (24.12% vs 37.99%). The point, as in Taijiquan, is that force is picked up throughout the movement.

Assuming an individual is capable of generating this force, the next thing is that it has to be expressed where it is needed. That is, it has to be directed and controlled according to the situation. Taijiquan has multiple means of delivering force. In a recent post the Chengoushui or “Water of Chenjiagou” website posted a short piece about fajin and four different ways it can be expressed according to Chen Fake. Chen Fake was renowned for his high level of Taijiquan skill, his tremendous physical strength and his practical experience. He listed the following methods of releasing force:
1. The force on the “outer-edge of the wheel” [at the edge of the circle] where an opponent can be hit without [seriously] damaging them.
2. The force from the inner strength of the wheel. Here he gave the example of Taijiquan’s lie jin (splitting/tearing force), of which he said “this strength can break bones.” Lie jin is used by emitting a very short and sudden twisting and tearing movement. On a cautionary note, it is not easy to experiment with this method as it is very easy to seriously injure your training partner’s joints.
4. The final method was bao fali or “explosive jin.” In Chen Taijiquan this strength is often compared to a sudden explosion akin to an earthquake emanating with no warning from the centre of the earth. Three generations earlier Chen Fake’s great-grandfather Chen Changxing vividly described the abrupt and unexpected nature of fajin: “Lift your hand like lightning flashing. When lightning flashes, there is no chance to close your eyes. Strike the opponent like thunder clapping. When thunder claps, there is no chance to cover your ears.”
