Keenan Cornelius a name synonymous with innovation and success in the world of Brazilian Jiu-Jitsu (BJJ). Born in Hawaii, Cornelius has carved out a unique path in the sport, earning a reputation as one of his generation's most creative and influential practitioners. From his early beginnings under the tutelage of BJ Penn to his meteoric rise through the ranks under André Galvão, and finally, to his current status as a free agent and founder of his own affiliation, Legion, Cornelius's journey is a testament to his relentless pursuit of excellence and innovation in BJJ.

His career, filled with numerous accolades and groundbreaking techniques, has not only earned him a place in the BJJ Hall of Fame but has also inspired countless practitioners around the globe. His contributions to the sport, particularly his development of the Worm Guard, have revolutionized the way BJJ is practiced and taught today.

Early Life and Background

Born in the tropical paradise of Hawaii on February 25, 1992, Keenan Cornelius was destined for greatness in the world of Brazilian Jiu-Jitsu (BJJ). His father, Tom Callos, a 6th-degree Tae Kwon Do black belt, introduced him to martial arts at the tender age of 4. However, it wasn't until he turned 14 that he discovered his true passion - Brazilian Jiu-Jitsu.

Keenan's journey into the world of BJJ was not a conventional one. His father, a big fan of mixed martial arts, opened a small gym for Keenan and his friends to train a couple of times a week. This informal training ground, coupled with the wrestling experience from school, laid the foundation for Keenan's future in BJJ.

  • At the age of 15, Keenan's life took a turn when he visited the BJ Penn Academy in Hilo.

Inspired by the training and the camaraderie, he decided to enroll in a college in Hilo so he could train every day at Penn’s gym. These formative years at Penn's academy, despite the lack of a full-time black belt coach, shaped Keenan's approach to BJJ and set him on the path to becoming one of the most accomplished practitioners of the sport.

As an author and a fellow BJJ practitioner, I can't help but be inspired by Keenan's story. His dedication to the sport, his relentless pursuit of excellence, and his ability to overcome challenges resonate with the values of the BJJ community. His journey serves as a reminder that with passion and determination, one can achieve greatness in their chosen field.

  • Keenan's first exposure to martial arts training began at a young age, under his step-father, martial arts teacher Tom Callos, who was B.J. Penn's first Brazilian jiu-jitsu instructor. 

At the age of 14, he began casual grappling training with friends. Shortly thereafter, he began receiving formal Brazilian Jiu-Jitsu instruction under Cassio Werneck, then training for three years under BJ Penn before ultimately joining Team Lloyd Irvin. Despite his high-level victories as a purple belt and above, Keenan claims to have had a poor competitive showing early in his career, prior to his joining Team Lloyd Irvin, a move which Keenan held responsible for his later success.

  • On February 28, 2012, Keenan won the Abu Dhabi World Pro Trials Montreal Purple belt +74 kg absolute division. In April 2012, Keenan competed in the World Pro Jiu-Jitsu Cup, winning his division (-82 kg.) and earning a bronze in the absolute division. On June 26, 2012, Keenan was promoted to the brown belt under Lloyd Irvin.
  • On February 27, 2013, Keenan announced his split from Team Lloyd Irvin. A few days later, it was officially announced that he would be joining Atos Jiu-Jitsu. After his transition to Atos, Keenan continued his run as arguably the most accomplished brown belt in the history of the sport, winning nearly every major tournament at his weight and open class, with the only exception being the 2013 IBJJF Brown Belt Absolute Division, where he placed second.
  • On September 14, 2013, Keenan was promoted to black belt under André Galvão.
