As far as key points are concerned, we have a few. The first one is the second kick is critical, even if you think yours is good, everyone can work on it. So definitely take that as a word of advice, second piece is the kicker is the most important part of your Butterfly. So even though this Butterfly presentation was technically dissecting the pull. The pull will be significantly hurt if your kick is not going well so it all goes back to that. As we saw on the videos too long of a breath can ruin your whole stroke. Breathing patterns are hard for me, when I swam butterfly I breathed one up, one down. I would say that that’s fairly common, but you can also kind of fiddle around with two up, one down or also one up, one up two down, depending on the length of your race or what you’re swimming for Butterfly.
