In his book ‘Wado-Ryu’ karate, Hironori Otsuka tells us that there are three kinds of strength - Physical Strength, Technical Strength and Mental Strength - and if any of those is deficient it will be “ the downfall of the individual “. It’s a common misconception throughout the martial arts that ‘technique’ is the key; if we have good technique then we will be effective in combat. The fact is that technique is no more or less important than physical fitness or mental conditioning. Many martial artists dislike this idea as it infers that those with poor technique can defeat those with good technique (if they lack the required mental and physical condition). A labourer on a building site (physically conditioned) who regularly gets involved in bar fights (mentally used to combat) could easily defeat the martial artist who concentrates on technique to the exclusion of the other forms of strength.
If we are to be able to effectively defend ourselves then we need to ensure that our training also develops physical condition and mental strength in addition to technique. The key is to ensure that our training is intense enough to encourage growth in all three areas e.g. we drill our techniques with intensity and to the point of exhaustion (stimulates physical strength) and no matter how much we want to quit or ease off, we then drill them some more (stimulates mental strength).
We need at least two sessions a week that take us to our very limits. They key is not duration but intensity. We can train for hours and never break sweat or we can work flat out for around two minutes and be close to throwing up. Real fights are extremely intense and, if our training is to be valid, we also need to train in an intense way. This intensity in training has many benefits besides increased combative effectiveness.
