regarding Sanchin:

Sensei, could you explain why we shouldnít practice Sanchin with 100% muscular tension?

"Hai, Sanchin should be practiced at 60% muscular tension. Sanchin is very good for the young. It is less good as one grows older. The Sanchin Kata is very hard on the internal organs as you age. Many of the Goju masters, including Master Miyagi himself didnít live to a great age. I believe this was the result of Sanchin training. As one grows older, ones body and ones power must grow softer as the understanding of karate becomes greater."
