  1. Only when lifting the head to breathe
  2. Only at each wall
  3. While the face is in the water ✔

Why: USMS says to breathe out while your mouth is underwater and breathe in when it is out. Holding your breath is a common mistake that makes each breath rushed.

Huh, didn't know that: USMS says to breathe out slowly, then give one last strong push of air just before you breathe in.
