So at that point I decided I was going to learn how to breathe on my right side as well.... although in a race I'll probably just revert to left-side breathing, since I seem to get more air and less water that way.
I guess it can if you are swimming 5-7 days a week for 1-2 hours at a time... is that exact? No. My point is this... I think you can injure the opposite shoulder if you swimming A LOT... our workouts... well, my workouts... 3,000-8,000 yards a week for 1-2.5 hours... it's doubtful. I'm not swimming that much.

I have been swimming with only right side breathing for YEARS (22 years)... and my left shoulder isn't injured.

But hey, all bodies are different... right?
