This video shows a summary of a two-person flow drill for the entirety of Tekki Sandan / Naihanchi Sandan. The drill follows the kata, move for move, and can be repeated endlessly. Tekki Sandan / Naihanchi Sandan builds on the methods introduced by the preceding two kata and is essential a kata to teach more advanced limb-control.
Such flow drills are good for time efficient practise of the bunkai of the kata, but they should not be confused with the direct application of the kata. The movements would not be applied in such long combination; but they can be drilled that way. This is just one drill of many.
We should also practise the motions singularity, in alternate sequences and in live drills so the kata can applied appropriately to the situation as it stands. This video was recorded as a summary for those who had already received detailed instruction in the drill. It is not a substitute for that instruction. I nevertheless hope you find it interesting.
All the best,
