Why OxyBoost?

As your instructor and athlete, I know what it takes to progress in freediving. Between our sessions, consistent breath-work practice makes the biggest difference. That's why I built OxyBoost — so you can train effectively on your own, with the same methods we use together.

What's Inside

O2 Table

Progressive breathing exercises that gradually increase your breath-hold time. The app adjusts intervals to help you improve oxygen efficiency step by step.

CO2 Table

Build your CO2 tolerance with exercises that progressively decrease rest time between holds. Essential for comfortable deep dives.

Box Breathing

Four-phase breathing technique used by athletes and military professionals. Inhale, hold, exhale, hold — perfect for pre-dive relaxation.

Relaxation Table

Gentle, steady breathing exercises focused on calming your mind and body. Ideal for recovery days and mindfulness practice.

Custom Tables

Design your own training tables with custom intervals. I can share personalized exercises with you directly through the app.

Progress Tracking

See your training history, track improvements, and stay motivated with detailed performance statistics.
