I recommend this book to all swimmers and all those who want to wear! It is super rich with a training log (100 sessions), explanations of technical swims and tools to better understand the training. Well documented, simple and clear, it is very accessible and is open to everyone. It is written with real sentences, understood by everyone, without technical terms indigestible and with many descriptive sketches. The sessions are great and can be adapted according to his purpose and his desire!
