Georges Hébert’s “Code de la Force” book was published in France by Vuibert in 1914.

In its foreword, the author wrote:

The purpose of this book is to define the question of physical strength, by precisely defining the elements that comprise it and to give it a practical means of measuring it.

Because of the lack of works where notions relative to strength are codified [at the time of his writing], errors and preconceived notions of all kinds were plentiful on this topic. Thus, many people believe that large biceps constitute a criteria for strength; others solely consider strong individuals that are capable of lifting heavy weights; others finally habitually apply the qualifier of “solid bloke” to anyone tall and big. However, it so happens many times that the individual with large biceps shows inferiority when it comes to running or simply quickly climbing a slightly steep hill, that the weight lifter is unable to jump over any obstacle, that the solid bloke cannot follow an individual of ordinary ability in a long walk, a hike, a hunting game etc. 

He later writes:

On the other hand, no method concretely defines the outcome of physical education or training, meaning the goals to achieve. The result is trainees and coaches having no clue what to do. One not only trains without ardor or enjoyment when training without a goal, but one wastes time inevitably by repeating certain exercises without benefit. This is why I believed indispensable the need to establish exactly what the “training load” of the trained or educated individual ought to be.

One of my favorite parts of this foreword is that Hébert recognizes the need for experimentation, course correction and adjustment, his work being far from definitive. Philosophically speaking, isn’t it the first step to acknowledge what one’s limitations are in order to improve upon them?
