On July 11, 2026, Nathan Cook made an impressive debut at SENSHI 32, defeating Francesko Xhaja by knockout and earning the special Knockout of the Night award, presented to him personally by the legendary Sam Greco.
Standing 2 meters tall, weighing 117 kg, and boasting an impressive knockout rate, the British heavyweight quickly caught the attention of fight fans. Outside the ring, however, he has a very different profession – working as an osteopath, helping people recover from injuries.
In October, Cook returned to Varna, Bulgaria, for the 6th SENSHI Invitational Camp, where he trained under the guidance of K-1 legends Semmy Schilt and Ernesto Hoost. It was during this camp that the documentary was filmed, offering a more personal look at the fighter behind the powerful knockouts.
In his conversation with Grant Waterman, Nathan explains why personal growth matters more to him than championship titles, what respect and sportsmanship mean to him, and why he is never afraid to face more experienced opponents.
The most emotional moment of the documentary comes when Nathan speaks about the loss of his father, who passed away unexpectedly just one day before one of the most important international fights of his career. The man who introduced him to sport and attended every one of his fights remains his greatest inspiration.
Nathan openly shares how he dealt with that devastating moment, why he decided to step into the ring despite the tragedy, and how he continues to turn his pain into motivation to move forward.
Filmed over three days in Varna, the documentary combines intense training sessions, personal conversations, and moments away from the ring to reveal the man behind the spectacular knockouts.
“Nathan Cook – Up Close and Personal with SENSHI” is a story of strength, loss, respect, and the pursuit of self-improvement. It is the story of a fighter whose toughest battles are not always fought inside the ring.
