Chaos- last Summer I learnt front crawl from scratch doing adult swimming lessons, although I am still v slow my technique is ok, bi-lateral breathing and all, It took about 5 lessons to get it and I can still improve loads. At our local sports centre the lessons are pay per session a bit dearer than a normal swim with very mixed abilities, some total non swimmers. You just tell the instructers what you want to learn. I am now screwing my courage up to learn butterfly- but that's impossible isn't it?
