Guides

How the tables work, how to breathe between holds, and how to keep dry training safe. Each guide lists its sources.

1. CO2 tables: what they train and how to do one How a CO2 table works, how to build one from your personal best, and how to run it safely on dry land.
2. O2 tables: longer holds with a fixed rest How an O2 table differs from a CO2 table, how to build one from your PB, and why it is the more demanding of the two.
3. How to breathe between holds: breathe-up, final breath and recovery breaths The three kinds of breathing in a dry breath-hold table — relaxed breathe-up, the final breath and recovery breaths — and how to do each one.
4. Measuring your static personal best safely What a dry static personal best is, how to measure it calmly, and how often to re-measure it for your CO2 and O2 tables.
5. Dry breath-hold training safety The rules that keep dry static tables safe: never in water, never alone, lie down, no hyperventilating, and stop at the first warning signs.
