Questions for the group,
I am interested in possibiliy introducing Tekki Shodan/Nihanchi to my class, my school has a heavy competition focus so it has generally been a neglected kata for us since it is not normally allowed as a first round kata in tournaments.
The other reason that I want to start teaching it is that It is an excellent kata for larger, more "stationary" indiviuals that are more interested in self protection than tournaments. Not that I don't think those students should learn the more agile, movement based kata, especially if they want to teach in the future. but that being said the idea of teaching katas that require very agile movements (say chinto) to people who's bodies and fighting styles simply are not built for it seems silly to me.
Teaching a 40 year old 140kg purple belt Chinto rather than Nihanchi seem like a disservice. Hence my desire to start teaching the kata.
That brings me to the title of this post, Nihanchi-Dachi hurts my knees when I do it the way that Iain suggests, and I am concerned that this makes it unsuitable for teaching to a lot of those same larger students since a lot of them have weak knees. Am I approaching this from the wrong direction and the kata will help to stregthen the kness, am I doing the stance wrong, should I look to more to the Hachi/Kiba Dachi versions of the kata, or just avoid it for those with weaker knees?
On a more general note does anyone have good training excerises/drills for stregthening knees joints?
