Learn to expel air effectively to simulate clearing water from the snorkel.
The objective is to understand that there is always usable air available, even after an exhalation, and to use it quickly and efficiently.

* Position yourself with the head posture from Exercise 1A.

Phase 1 — Lungs full

* Inhale normally through the mouth.
* Briefly hold the breath.
* Expel the air quickly and forcefully through the mouth into the snorkel.
* Engage the abdominal muscles to strengthen the expulsion.

Phase 2 — After exhalation

* Exhale passively.
* Briefly hold.
* Expel another short, powerful burst of air.
* Engage the abdominal muscles to produce the expulsion.

Imagine that there is water in the snorkel and that you need to clear it quickly.

* The expulsion is short, quick, and directed.
* The abdominal muscles are engaged during the expulsion.
* The air is projected efficiently, without dispersion.
* Both situations are tested: lungs full and after exhalation.
* The body remains relaxed outside of the expulsion phase.

* I am able to produce a short and powerful burst of air.
* I feel the engagement of my abdominal muscles during the expulsion.
* I understand that I can still expel air even after an exhalation.
* I feel capable of clearing water from a snorkel.
* I remain in control without stress.
