Imagine having to press down on a make-believe button when streamlining in the breaststroke and releasing the same button to breathe. Thinking in these terms can help you better understand breaststroke breathing timing. During the entire outward sweep phase of the pull, your chest lightly presses down on the switch. As the arms scull inward, it releases the button, and the shoulders rise for the breath. To repeat the cycle, press down on the button as your body reassumes the streamline position. For “wave-style swimmers,” the chest-press action is more exaggerated. Try it in practice today and see how it feels.
