Deliberate Practice

I watched a conference presentation, Deliberate Practice in Software Development, at work last week and thought I would blog the key points that I believe pertain to martial arts (and music) training.


Presentation Summary
In the nature vs. nurture debate, researchers have declared nurture the winner. People who excel are the ones who work the hardest; it takes ten+ years of deliberate practice to become an expert. Deliberate practice is not about putting in hours, it’s about working to improve performance. It does not mean doing what you are good at; it means challenging yourself under the guidance of a teacher.


Deliberate Practice—activity that's explicitly intended to improve performance, that reaches for objectives just beyond one's level of competence, provides feedback on results and involves high levels of repetition.

  1. Feedback needs to be immediate.
  2. Identify the skill to be improved.
  3. A coach is needed to help identify problems and direct the practice.
  4. Regular and intensive practice.
  5. Don't do what is easy. Practice the things that are difficult and challenging.

Greatness isn't reserved for a preordained few but available to everyone, like the pursuit of happiness, while being restricted to those who put in the work year after year.

Japanese Terms

The instructors at the dojo have begun to expect black belt candidates to know the Japanese terms for things. The first new term to me, other than the names for the arts, was "koshi". Upcoming blogs with include the Japanese name for the basics.


Koshi is the ball of the foot. It is generally what we make bodily contact with when we kick.


I asked a few of the black belts what the term was and they all answered quickly. But when I asked them to spell it they didn't know for sure. Perhaps it has been a long time since they wrote it down in their notebooks.


Prof. Jenkin's Martial Arts Dictionary defines koshi as "ball of foot [tiger's paw]". There are seven different kanji for koshi listed plus Koshi=Confucius. Also note the there are three other kanji for ball of foot :)


In Jujitsu the term koshi is used to refer to the hip or waist.

Kusanku Kata

Kusanku was a Chinese emissary who lived in Nakashima-Yukaku, Okinawa. Master Sakugawa studied with Kusanku for six years before he created this kata in order to codify Kusanku's teachings. After their first encounter on the bridge it is said that Kusanku commented that Sakugawa need to learn the why of martial arts, not only the how.


Here is an old film (1960's) of Master Tatsuo Shimabuku performing the kata.
