Internal and External

This cycle is also known as the
“Primary Cycle Of Development”

This cycle will help a JKD practitioner discover and develop the difference between Hard and Soft by combining both qualities together.

The Eight Elements

Internal

Emptiness - the art of Emptiness is the last level of training in JKD. This is when you react naturally to your environment, without thinking.
Stillness the art of Stillness occurs when you are aware of your surroundings and not charging your opponent blindly. You are not distracted by anything.
Sinking the art of Sinking occurs when all of your energy is focused into your middle, the center of your gravity. This enables your strikes to be well grounded and most forceful.
Softness the art of Softness means your moves are "fluid" and concise. Your strikes will be forceful without exerting unnecessary energy.

External

Technique the art of Technique is when you have mastered the movements of JKD. They are second nature to you and you know when to apply the proper technique in real life situation.
Timing the art of Timing is most essential and it fits hand and hand with technique. Knowing when to apply the technique at the right time. Even if your technique is the best, without proper timing the technique is useless, and your distance, speed, and rhythm will be misjudged.
Angle Structure the art of the angle structure is accuracy. In order for your angle structure to be effective your moves must not be sloppy and must be well focused.
Power the art of Power will develop as your technique, timing, and angle structure come together. Without technique, timing, and angle structure, power is useless.
