PSE power speed endurance static apnea tables to increase Co2 tolerance:

First determine your maximum effort inhale breath hold. Do lying down in parasympathetic NS. Rest and take a few good breaths and then inhale through nose and hold for the longest possible time. Use that time.

Divide your max inhale by 50% so for example if your max hold is 2 min, use 1 min for the breath hold tables.

Do once per day and no more, minimum three times a week.
