In this video Renee goes into detail about how to do the relaxation breathing of a freediving breathe-up and guides you through the entire process.
This is the first video of the Proper Breathe-up for Freediving series. You can find part two on final breaths at: The Proper Freediving Breathe-up – Part 2
A proper free-diving breathe-up utilizes breathing techniques from both videos; generally 2-3 minutes of relaxation breathing followed by 20-45 seconds of final breaths. This breathe-up is suitable for static apnea, dynamic apnea and open water freediving.
