There a couple of Freediving books available at the moment (some of them you can find online), as well as different Freediving manuals in each Freediving system.
Some of them are very useful, some not that much.
In this Freediving book I will try to gather as much useful and updated information about the Art of Freediving as possible. I want to make this book useful for both beginners Freedivers as well as Freediving Instructors (especially who just start teaching).
If you feel that some information not accurate, please feel free to contact me and suggest your correction. Let’s do it together!
