More experienced taekwondo practitioners than me would not notice this probably.
We did one step sparring drills and I was unusually with another black belt so we attempted some basic wrist techniques. I noticed the difference in force, they were using too much and sometimes pushing downwards. In Systema session someone pointed out that I was doing the same thing. So today I didn’t and was able to achieve same result with less effort and less energy.
Had interesting chat with another senior practioner after the session, he has recommended to practice thousands of breakfalls, read the Dao de Jing and apply this in all aspects of life.
