I learned to swim free-style as do most, largely by just taking things in as I went along.
Along came the web, and I began to analyse my stroke and get more technical. One of the things I learned was that the timing of the kick is important. This was not something I had (or have) ever been taught. I came across on one of those internet-thingy sites. It said that after learning to swim from the hips, as one arm enters the water, the same leg should give a major beat. I tried it and it worked. There is something almost miraculous about it.
Instead of having two engines, one at the back and one at the front, you become just one engine, and the whole is bigger than the sum of its parts.
Fine. In our lane we discuss these things, and I have tried to spread the word. I have been quite unsuccessful. People occasionally manage it, but not with any conviction.
This morning I came across an old link to Shinji Takeuchi‘s youtube videos. He really does swim with an amazing stroke. On checking, what struck me sharply was that he does things the other way around. As the right arm goes in, the left leg kicks down. I must bow to his wisdom, and will try it.
I will let you know, but if anyone has any comments . .
