What are the best drills to practise bi-lateral breathing?
One thing people forget is that you can mix up patterns. I used to hate breathing every three as I find turning my head to the left uncomfortable. I used to breath 3-2-2-3 so I would put a third breath in as this assists in evening out my stoke and also in open water it helps to see all around you. But then I would breath 2x to my right as this feels more natural. As for drills, just practise and persevere – it will get easier!
