Below is a download link to a partially translated text from Georges Hébert (written in 1912).
I had previously seen an abbreviated version of this translation (hosted at americanparkour.com), but the above listed link includes much more detail.
If you are not familiar with Georges Hébert, you may wish to review the following:
Ironically, what is demonstrated in his 1912 text is well beyond what many healthy adults are capable of performing 100 years later. Many of the so-called advancements that are espoused today are nothing more than attempts at quietly rehashing the past. While today’s generation has certainly advanced in regards to performance enhancing drugs, performance without such drugs has not changed nearly as much as many believe.
As you study strength athletes from previous generations, you’ll realize that some of the best lessons have already been taught. Plenty can be learned from those who came before us.
“The final goal of physical education is to make strong beings. In the purely physical sense, the Natural Method promotes the qualities of organic resistance, muscularity and speed, towards being able to walk, run, jump, move on all fours, to climb, to keep balance, to throw, lift, defend yourself, and to swim.” – Georges Hébert
