CO2 Table Generator

A CO2 (carbon dioxide) table is a breath hold training protocol designed to increase your tolerance to elevated CO2 levels. The hold time stays constant while rest periods get progressively shorter, forcing your body to adapt to higher CO2 concentrations.

This is one of the most effective ways to extend your breath hold time. Regular CO2 table training reduces the urge to breathe, allowing you to stay calmer and hold longer.
