Took a lot of work and time. Looking at the program outlined in the video, many of the same concepts were used—except it wasn't as targeted as he mentioned. We did partner work, which also wasn't based on any particular approach other than attempting to endure as much pain as you could, and trying to force your partner into the position of the stretch we were working on at the time. That wasn't something I was able to maintain, nor felt the need to.
After watching the video, thinking of going back using some of the core concepts he mentioned...The problem, sometimes stretching itself can introduce tension....
Some "Tang Soo Do" ( 당수도 ) practitioners I used to know had some very "bitter" ways of stretching...
One had to be carful about "tearing" things that were supposed to be stretched.
The terms song (松) and fang-song (放松) are fundamental concepts in Chinese internal arts like taiji. Fang-song is the physical skill of quieting the nervous system's alarm bells (the stretch reflex) among "other things"
the body can move more freely and efficiently, acting without tension in movement.
In China, we did something similar to what is called wall squats—but without the wall a squat with back plum vertical.
Normal practiced with the back of the head, back and heel touching the wall as one squatted...
I sometimes use that to show people who think something is easy that it is not so easy until they actually try it.some might find this stretch interesting ..
Also called wall squatting although it's done a little differently..facing the wall...
The nose and toes are touching the wall, while doing it...
