Breathe-up, static hold, CO2 and O2 tables and box breathing. Train your apnea on dry land, the right way.
Train only on dry land, never in or near water, sitting or lying down, with a buddy nearby. Stop at once if you feel dizzy, tingly or lightheaded. This is a training aid, not medical advice.
BEFORE YOU START
A few questions and the safety rules
A calm breathe-up, then hold your breath and the timer counts up. Tap Stop the moment you breathe. Your best hold is saved on this device.
Pace: slow inhale 4s, long relaxed exhale 6s. On the last breath take a full, calm breath in, then start the hold. During the hold, tap First contraction at your first diaphragm strike, then Stop when you breathe.
Hold time stays the same, the rest between holds shrinks. Builds tolerance to the urge to breathe. Keep the hold comfortable, this table is about the rests.
Set your own hold, first rest and how much the rest drops each round. Rest will not go below 5 seconds. Tap First contraction during each hold to log it.
Rest stays the same, the hold grows each round. Builds your maximum breath-hold. Push the later holds, but never past discomfort.
Set your own first hold, rest and how much the hold grows each round. Tap First contraction during each hold to log it.
