How to Swim Faster: It’s All in Your Head
Another great way to practice the correct head position is by using a center-mount snorkel. FINIS carries a few that I highly recommend. The snorkel will allow you to breathe constantly without breaking your head position to breath. Practicing this will get your body used to the correct head position and eventually you alternate sets with and without snorkel to slowly introduce the complexity of turning the head for air without significantly raising the head or breaking the head and spine alignment.
