Learn to hold your breath for 3 minutes. Static Apnea Trainer provides breathing exercises that help your body to adapt to lower oxygen levels. Most of these exercises consist of breath holds and rests with specific lengths — apnea tables or static tables (apnea training based on repeated intervals of breath holds).
