Emphasis on visual confirmation is what I was referring to, but also, there is not any emphasis on tighting specific muscle groups either.Actually, the appearance itself of tension in Sanchin isn't important. It's the fact that you are tightening the right muscle groups in the correct combination and spacing/intensity that the teacher is looking for with his eyes and hands. It may be that a very slender person may not display visibly the tightening - I've run into this before with a rail thin student - and then the disrobing becomes less important.
Not sure if an emphasis on visual confirmation of tension is what you meant to convey, but I just wanted to clarify this for anyone else reading.
Yes.But my question has been answered between you and leadleg. Sounds like there is supposed to be a degree of dynamic tension performed, but you are more concerned with the breathing half of it than the muscular intricacies.
