"Always practice dry-land apnea in a seated or lying position to prevent injury from fainting; never practice breath-holding in or near water without a certified safety partner."
The urge to breathe is primarily triggered by rising CO2 levels, not low oxygen. Increasing your CO2 tolerance delays the involuntary breathing contractions, allowing for longer, more comfortable holds.
Yes, dry-land training is the safest way to build physiological adaptations. However, you must never practice near water or while operating machinery due to the risk of hypoxic blackout.
