Select your preparation time to get ready for the training session. A good value is 2 - 3 minutes to do pranayama breathing, reduce your heart-rate and mentally prepare for the training. Choose a breathhold time where you can comfortably hold your breath: A good value is 60-70% of your maximum breathhold time. Choose a recovery time that allows you to hold your breath for the same time as you did before. 1 minute is a good starting value. Set either an increase for your breathhold time (start with 10 seconds) for O2 Training or set a decrease of your recovery time (start with 15 seconds) for CO2 tolerance training. Select 8-10 rounds. Tap "start" to begin your training session. Never hold your breath under water without a qualified person supervising you and without proper freediving training/certification!
