Breathe with Gert
Breathwork from a former national record freediver. More calm, longer breath-holds. No water needed.
Calm is a skill. The breath-hold trains it.
Freedivers learn to stay calm in the most stressful moment there is: when the urge to breathe hits. Every second you add to your hold is proof you're getting calmer.
A calmer mind
Every day, not just during practice.
Switch off easier
Wind down after work and at night.
Longer breath-hold
Measurable progress, week after week.
Steady under pressure
Your breath stays slow when it counts.
Your breathwork progression
Start with the 6-Week Breathwork Challenge: learn to stay calm as CO2 builds up, 15 minutes a day. Then the Breath-Hold Builder takes you step by step toward 5 minutes, and the Advanced Toolkit keeps you growing.
