If you are not satisfied with the classical “it’s always been done this way” and you are curious to learn and don’t want to be limited to “driving your vehicle” without knowing when to change gear, because you want to understand how its engine works…

This book is for you.

What will you find in the bible if you are a beginner?

You will find more than 25 years of knowledge and experience captured in a practical guide that will show you, from beginning to end, the entire path you have just embarked on. 

You will be inspired by the lessons learned from the author’s personal history, see yourself reflected in it over the years and avoid his mistakes. 

You will solve the typical doubts about whether it is better to train with machines or with free weights, the differences in approaches between Natural and Doped, what is the natural limit and how to estimate where yours could be, the intimate relationship between strength and hypertrophy and how to plan your training routine in the long term, based on your level and experience. 

You will discover that there is a community that shares principles and values, a natural critical mass that is NOT willing to make “a pact with the devil” to get the physique they crave, they are NOT obsessed with the end result, but choose to enjoy the journey and take pride in the fact that everything achieved is their own merit. 

This is how self-esteem and discipline are built and applicable to any other area of life… these are all athletes and REAL examples that you will find in the book, real champions who have applied in their flesh all these teachings, real examples to follow from which you can be inspired to achieve what you set out to do.     

What will you find in the bible if you are advanced?

You will find a long-term work logic that has proven to be a winner in the most prestigious international natural bodybuilding circuit in the world.


You will have in your hands step by step, routine after routine, to print and take to the gym, an annual programme with its technical phase, strength phase, transition phase, hypertrophy phase and peak phase, experienced for years by our best natural WNBF champions.


I’ll walk you through the logical reasoning behind the design of each program, so you can be inspired to create your own ones.


You will discover in detail the typical mistakes in a competition preparation and the strategies that have allowed our athletes to reach a condition out of the ordinary and are allowing an exponential increase in the overall competitive level of all those who are putting it into practice.


You will finally understand how to apply current scientific knowledge “in real life” and combine it with practical experience in the field of natural bodybuilding training and competition.

Are you still here? Maybe you've read dozens of books that haven't helped you?

i know, it's always the same story...

You dive into a new reading full of enthusiasm, hoping to extrapolate some key teachings to continue improving and you end up immersed in “a pile of straw”, an endless amount of contradictory information, a list of theories and possibilities where “everything works” and finally you find no useful conclusions.

Hopefully you end up concluding with the same as always… a huge “IT DEPENDS” and in practice, you go back to the gym to do the same as always, the same as before you read the book. 

For this reason, with the Bible I wanted to write a direct, practical and immediately applicable book, where everything is interconnected and in which to find a path of experienced success that our best Natural Bodybuilding champions have already walked. A complete manual that could be a constant source of motivation and inspiration, to go to and learn from for years, for a lifetime… and not end up being just another forgotten book on the shelf.

It’s the book that did not exist and that I would have wanted to have in my hands when I started in the fitness industry, more than 25 years ago, that would have prevented me from going around in circles and that would have never allowed me to doubt that…

100% NATURAL it can be done!
