Freediving book “Longer and Deeper”

It wouldn’t be a surprise if I say that it is not that many available Freediving books around. The last one which I read was “Oxygen” by William Trubridge. And I am also in the middle of “Manual of Freediving” by Umberto Pelizzari.


So, it was a pleasant surprise when the book “Longer and Deeper” by Jaap Verbaas was published a couple of months ago.

I don’t know the author personally, but I read a couple of his articles on the website Freedive Wire and also saw a couple of thoughtful comments here and there on different social media.

So, I was pretty excited to get his book. Is it worth to get it?

My opinion – 300% yes. First of all, it is not a “beginner level” manual, where an author explaining MDR or hyperventilation and you are skipping it because there is nothing new there. It is also not complicated medical research where you should Google every second word to understand what the article is about. It is somewhere in the middle.

But what is it exactly about? The book is mostly about how and why to train “dry”. There are exercises with explanations on how to do them and what exactly you will get from it.

I am not telling that these exercises are unique and you couldn’t find them somewhere else. But I was hooked by simple explanations about how exactly they work as a cross training for a Freediver. I haven’t met such detailed explanations before.

For whom this book will be useful? If you are a highly experienced Freediver with an academic background in the human physiology – then probably you will not find anything new. For anyone else – give it a try. Especially if you are not simply trying to increase your PB’s, but also want to understand deeply processes in the body during apnea training.

For example for me, none of the exercises was new (ok, I never tried apnea squads), but an explanation of how it works boosts my interest to understand more about certain parts of human physiology. So, because of it, I spent the last month trying deeply understanding different processes in a human body during apnea.

Overall this book is definitely in the TOP list of Freediving books for me at the moment and I definitely recommend reading it. And also I hope the author is not going to stop and will continue his researches and we can expect the second edition in the near future!
