Confessions of a Lane Six Swimmer

Bilateral breathing is the next swimming skill I'm learning. Basically, I've been breathing on my right side every 4 strokes. I need to use alternate side and breath every three strokes. This skill will help me to balance my stroke so I can swim faster. In addition, I want my lat (back) muscles to develop evenly on each side.
So far, I only do bilateral breathing during 25- or 50-yard drills. It doesn't come naturally, so I have to do a stroke count in my head. It's easier to do during pull drills when I already focus on my upper body movement.
