In traditional Kung Fu there is a distinction that surprises many beginners: muscle strength is not the strongest force. There is a subtler, more intelligent form of strength — and this is what internal martial arts pursue.
We call these two qualities of power Lik and Geng.
Lik – The Strength of Muscles
Lik is what we all know: raw muscle strength. Bodybuilders, heavy laborers, weightlifters — they all rely on Lik.
- Characteristics: raw muscular force and endurance; visible muscle mass, associated with tension.
- Training: strength training, weightlifting, hypertrophy exercises.
- Strengths: useful for physically demanding tasks requiring pure power.
- Limits: rapid fatigue, stiffness, and – paradoxically – a blockage of a more effective form of power.
Geng – The Art of Effortless Strength
Geng goes far beyond muscle strength. It is intelligent, often invisible force — arising from several factors at once:
- Skill and technique through precise, economical movements
- Speed and timing for perfectly-timed actions
- Control and coordination of the entire body
- Relaxation and looseness enabling explosive energy
- Inner structure and rootedness for stability
The puma example illustrates the principle: pumas lack excessive musculature yet can jump up to seven metres through perfect coordination, timing and relaxation.
Why Geng Leads in Kung Fu
Traditional inner martial arts favour Geng development for four reasons:
- Efficiency and sustainability. Geng generates significant power without excessive bodily strain or joint wear. The movements are economical and joint-friendly.
- Everyday applicability. Challenging situations rarely announce themselves. Geng provides immediately accessible power from a relaxed state — just as a cat reacts instantly from rest.
- Lifelong growth. Unlike strength-focused sports that often become difficult with age, Geng deepens throughout life. It becomes increasingly subtle and refined.
- Superiority in martial context. Excessive Lik slows reaction time and blocks energy flow. Geng enables swift, unexpected actions that are difficult to counter.
The Development of Geng
Cultivating Geng requires continuous refinement and deep body understanding — the “how” comes before the “what”. General principles:
- Prioritise relaxation and release unnecessary bodily tension
- Develop awareness and proprioception to perceive the body more finely
- Emphasise precision before applying force
- Practise with patience and dedication
Conclusion: More Than Just Muscles
The distinction between Lik and Geng reveals a deeper understanding of genuine strength. While muscle strength has its place, Geng represents a more intelligent form of power rooted in efficiency, skill and inner harmony.
For those who want to go deeper, the concept of Qi – the life force the Chinese tradition places behind Geng – opens the next level of this perspective on strength and movement.
True strength often manifests not through tension — but through composed readiness and skillful movement. An insight that reaches far beyond martial art: into everyday life, work, and living itself.
