TL;DR: What is the thinking behind turning to breathe every stroke (i.e. every two arm pulls) in freestyle?
Isn't this wasteful, since breathing necessarily disrupts your flow?
I'm a keen swimmer, swimming 3-4 miles a week freestyle. I breathe every 3 strokes (six arm pulls) and thought this was a great idea since
- it doesn't disrupt my stroke to keep turning to breathe
- it presumably means I have decent lung capacity.
But then I see Michael Phelps and all the others breathing each and every stroke, and I can't exactly argue with them. Why?
