O2 Table Generator

An O2 (oxygen) table is a breath hold training protocol designed to help your body adapt to lower oxygen levels. Rest time stays constant while hold times progressively increase, training your body to perform with less available oxygen.

O2 tables complement CO2 tables by targeting the other side of apnea performance. While CO2 training reduces the urge to breathe, O2 training improves your body's efficiency at low oxygen saturations.
