I am completely self taught. Six months ago I couldn’t swim at all and by following YouTube videos I have taught myself front crawl. I took the plunge and had my first swimming lesson with a coach over the weekend. I asked them to advise me on what drills to use to further improve my technique, and their reply was drills are pretty pointless unless you’re an elite swimmer! I wanted to run this by you as I wasn’t sure that this was the correct approach.
