How can improve my breathing in swimming?

This wil help (we do this at my swimteam) go under water and do dolphin kicks without breathing for a 24 1-2 breathes is okay the first few 25's but try having non. Your lungs will burn and feel like there Gina burst and it's normal our brains just think we need oxygen all the time but they don't. If you start running out of air and you can't hold it anymore scream inside your head. You could also do flutter kicks underwater and normal freestyle without breathing.
