What is the purpose of this blog? I will talk about monofin technique for freedivers (DYN and CWT). I have no intention to give you an absolute truth about monofin technique, I will just explain to you my 28 years of understanding of this particular technique. It will be only a way, my way, to describe what you need to know to swim better with a monofin as a freediver. I will explain it with my English, which, I'm afraid might not be perfect!
