I am trying to teach myself front crawl. I can do about a third of a length at the moment and can breathe on either side just about, but I am not sure about the arm action.
As my arm goes into the water should it just be (a) slightly bent but stretching out as much as possible in front of me or (b) very bent and not that stretched out or (c) something else?
I have tried looking online and watching others, but I am still not sure. I could almost do with a line drawing or something to get it.
