We often get questions about whether the book is suitable for a certain indiviudal. Some athletes worry the book will be too science-heavy to understand, while knowledgable and experienced practioners wonder how in-depth the book is.

The book was created to be the most comprehensive resource on this topic. Not just on the theory and science, but also an in-depth explanation of how we put all these recommendations into practice.

While some of the sections on the science may get deep, we have made sure that afterwards we explain what all of that means for practice.

We are confident even the most experience, knowledgable sports nutrition professionals will learn a lot from this. Similarly, we feel that athletes can implement all the recommendations, even without understanding the sections that get into the underlying science.
