Having never been any good at it, I thought its about time I mastered it.
I know the basics of a good stroke, but its the breathing that gets me. I'm in the habit of breathing every third stroke, so I alternate the side, and time-wise I find I'm not "ready" for a breath after just 2. However, after a couple of lengths of the pool, I have to stop and burp as I seem to be swallowing too much air.
I hold my breath whilst swimming, then breathe out as I lift my head to the side, breath in and carry on.
What's going wrong?
