Sam Chien Be/ Sanzhanma/ Sanchin-dachi/ Three Battles stance

[yat_chum]

In the system of White Crane that I practice the Sam chien be (three battles horse) is the main fighting stance and looks very much like the following pictures.

Recently one of my work colleagues said to me that this stance is damaging to the kidneys as it disrupts the flow of chi. What does everyone think about this?

there is a chi-gung exercise called washing the kidneys, and it utilizes a stance almost identical to this, so I doubt this to be true.

I think that it's yet another example of mixing systems in a way that was never intended: "kidneys" from a TCM perspective have pretty much nothing to do with the actual organ from a so-called "western" anatomical paradigm; meaning hat you can look at the "kidney" function from a TCM viewpoint and have them be all "out of balance" and then evaluate the kidneys from so-called "western" viewpoint and they can be perfectly fine (and the patient can be completely asymptomatic as well);

from either perspective though, I don't see what's wrong with that particular stance in the least;
