🫁 Join my breathwork & CO2 tolerance community. Freedivers learn to stay calm in the most stressful moment there is: when the urge to breathe hits. That calm is a skill, and the breath-hold is how you train it. Every second longer is proof you're getting calmer. 👋 I'm Gert Leroy, freediving instructor and former national record holder. I started at 40. At 51, I still train calm first, numbers second.
