The Story of a Champion By Cristian Bosch

“Pagar el Precio” (Paying the Price) is an extraordinary book that retraces the memories and remarkable career of Cristian Bosch, a multiple World Champion of the WKN.

Through its pages, this book tells the story of a fighter who dedicated his life to martial arts, discipline, sacrifice, and the true spirit of combat sports. It is a powerful journey through the victories, the challenges, and the determination required to reach the highest level of world competition.

The book also highlights all the people who played an important role in the career of this great champion—trainers, teammates, friends, promoters, and supporters—those who stood by him throughout his journey and contributed to the success of an exceptional athlete.

The WKN has always been an integral part of this story. More than an organization, it represents a united family built around respect, loyalty, and the values of sport.

“As World President, I am deeply honored to have received this book directly from one of my great champions, dedicated with words that truly moved and touched me. Looking back at all the years that have passed makes this moment even more emotional.

It also brings back memories of my dear friend who left us far too soon, Jorge Acero Cali. From wherever he is today, I am sure he would be very proud to see all that has been accomplished and the legacy that continues to grow.”
