Matt Thornton

After a much smaller jiu-jitsu black belt repeatedly submitted him, JKD instructor Matt Thornton founded Straight Blast Gym and built it around aliveness.

Biography

Matt Thornton is an American martial arts coach and the founder and head coach of Straight Blast Gym (SBG), an association of gyms based in Portland, Oregon. He came to Brazilian jiu-jitsu from boxing and Jeet Kune Do, and built his teaching around what he calls aliveness: skills are practiced against a partner who moves, resists and has timing of their own, rather than rehearsed as fixed routines. He holds a black belt under Chris Haueter, and the second person he promoted to black belt, John Kavanagh, went on to coach Conor McGregor. Boxing, the Army and JKD Thornton was born in California in 1969 and grew up in the San Francisco Bay Area. He took karate lessons at about ten, but not for long. Boxing came afterward, and SBG's own history treats it as the real beginning of his martial arts career. After serving in the US Army he took up Jeet Kune Do (JKD) in 1988. In 1990 he left California for Portland, Oregon, and spent just over two years running and teaching at an academy devoted to JKD Concepts. Among the JKD instructors he met there was Burton Richardson, whom he later credited with the whole of SBG's weapons curriculum. By his own account, those years left him doubting how JKD was usually trained. Instructors who dismissed karate kata spent long sessions on partner forms and trapping drills that, to him, were kata by another name, while wrestling, which showed up in almost every real fight, got little time. He later told the Daily Inter Lake that he had come to feel the art's message had been lost, and that he could not go on teaching something he did not think was real. He has also described sitting by himself in a Portland café, dreaming up a training environment that would apply science to fighting hand to hand. What he had in mind, he later realized, was an MMA and self-defense gym run on scientific lines, years before there was a UFC. The newspaper ad The turn came through Fábio Santos, a Rickson Gracie black belt who had come to Portland to work making surfboards. Santos put an ad in a local newspaper offering money to anyone willing to fight him. Thornton answered it, reasoning that he and his training partners were getting beaten up anyway and might as well be paid for it. The outcome was one-sided. Santos was much the smaller man, yet he closed the distance again and again, took Thornton down and submitted him, and did the same to everyone else. Thornton has said that being tapped out by a triangle choke, with no visible effort on Santos's part, felt like magic, and that he knew at once he had to add it to his own training. All of this happened before MMA and before the first UFC. He learned from Santos while Santos was in Portland and began passing the material on in the Friday class he taught. Through Santos he also met Rickson Gracie. At a seminar Thornton attended, he has said, Rickson tapped out a roomful of judo black belts in seconds, without using his hands. SBG's history credits the meeting with Rickson, together with boxing, with doing more than JKD to shape his idea of aliveness. Rickson later awarded him his blue belt, in 1993. A gym of his own When Thornton tried to bring jiu-jitsu into the academy's curriculum, he met resistance. His partners there were not convinced that fights end up on the ground, and after serious disagreements he went his own way. He opened a club about forty miles to the south, far enough not to compete directly with his old school, in a very small room he shared with a friend, a black belt in judo. That first Straight Blast Gym opened in Keizer, near Salem, in 1992, and it was the first academy that was entirely his to run. Everyone assumed, he told the Icelandic site MMA.IS in 2004, that he would never draw enough students to make a living, and he himself fully expected to need a full-time job. The name nodded to his JKD background: the straight blast was a trademark technique of Bruce Lee. He picked the word gym over academy or institute so that people would understand it was a place to train and sweat. A larger SBG opened in Portland in 1994 and remains the headquarters of the international association. A few years after the first gym opened, Randy Couture started coming in to work on his stand-up and his jiu-jitsu on the ground. SBG credits those sessions with changing how it trained the clinch, which until then it had treated as JKD-style trapping. Couture remained at the gym for some time, and Thornton was in his corner for one of Couture's UFC fights. Fightland quoted Couture as liking the way Thornton broke technique down and gave every move a philosophy and a meaning. In a 2009 interview Thornton named Couture and Rickson Gracie as the people who had most influenced his growth as a martial artist. He described his own competition years as the period when he was least able to help his athletes, and said that top competitors frequently make poor coaches. What aliveness means In a 1999 interview for a new video series, Thornton laid out five core principles for the SBG curriculum: aliveness; adaptability across stand-up, clinch and ground; coaching; attitude and philosophy; and conditioning. Aliveness he broke down into movement, timing and energy, the same three elements SBG still names today, with energy understood as resistance. Asked to define it in 2005, he called it right action at the right time, grounded in timing and authenticity, and argued that the way an art is trained decides how effective it is. Alive does not have to mean rough. SBG stresses that resistance is added step by step, and most skills are taught in three stages that it calls the I-Method: introduction, where a move is learned without resistance; isolation, where it is drilled against gradually increasing resistance; and integration, where the position is sparred. A participant at a 2004 seminar he gave in Reykjavik, writing for MMA.IS, found him soft-spoken and a natural teacher. He took each move through those stages and, rather than correcting mistakes directly, asked students why a position had failed so that they would reason it out for themselves. Speaking to Fightland for a 2016 article, Thornton judged the argument only partly won: even most MMA coaches still equated aliveness with sparring, when alive training did not need to be hard or fast or to damage the brain. The 1999 interview also set coaching apart from teaching. Coaching, in his terms, enhances performance, while teaching delivers a curriculum, and the three elements of coaching at SBG (experience, awareness and responsibility) came directly from John Whitmore's book Coaching for Performance. The gym had no ritual, no titles and no foreign terminology. There were no sifus or gurus. Coaches earned respect by wrestling and sparring with anyone in the room, and a technique counted only if it worked in sparring. VICE's Fightland site described how this worked on a real problem. A large newcomer kept submitting SBG members with a neck crank that trapped the head and arm. Thornton treated the gym as a laboratory until they found a simple frame, braced with the leg, that needed no strength. When he taught the problem at a later seminar, he first had the participants work on it in groups and let them fail, and only then showed them the answer. Other principles recur in his interviews. In 2009 he said the biggest mistake new grapplers make is chasing new techniques instead of fundamentals, posture and position, and that learning this from white belt could make progress three times faster. In a 2013 mission statement, around SBG's twentieth year, he wrote that he wanted to produce "scientists of fighting": people who understand the universal principles that make techniques work, not collectors of techniques. SBG describes his main concern as superstition in how athletes, fighters and martial artists train, with aliveness meant as a tool for separating fact from fiction. Critics and converts His first instructional series, Functional JKD, came out in the late 1990s, and its first tape was titled Aliveness. SBG says the tape stirred up fierce debate and sold worldwide, and that Black Belt magazine voted it into its top five self-defense videos. Fightland reported that in those years Thornton angered much of the martial arts world with seminars, online forum posts and articles arguing that many traditional techniques did not work. Black Belt put him on its cover under a headline declaring that his JKD had shaken up the martial arts world. At the time, every seminar he taught began with a talk on aliveness. By 2012, when Portland Monthly profiled him, SBG's gym in Northeast Portland was a calm room with classical music in the background and a reputation for full-contact training. The magazine described him carrying jiu-jitsu's emphasis on sparring into boxing, judo and Thai kickboxing, and writing off non-contact drills and martial arts mysticism as of little use for self-defense. It also traced a wider, arch-skeptical outlook he promoted in blog posts, videos and interviews, aimed at rival martial arts schools and at faith-based thinking alike, and summed up in his line "Belief absent evidence is a vice." Traditionalists disliked his criticism of dead martial arts, as he called them, and the magazine quoted the San Francisco instructor Gary Moro questioning so-called reality-based training. Peter Boghossian, a philosophy professor at Portland State University who trained at SBG, told the magazine that Thornton could explain complicated ideas plainly to a broad audience. Thornton's own point was that becoming good at jiu-jitsu takes thousands of losses. Black belt under Haueter After the blue belt from Rickson Gracie in 1993, Thornton's purple belt (1995), brown belt (2000) and black belt all came through Chris Haueter, the last at a ceremony in 2002. Thornton met Haueter, one of the early American black belts known as the dirty dozen, in 1993. Haueter became a regular visitor to Oregon for seminars and training, and Thornton valued his conceptual, no-nonsense approach. Haueter has called Thornton his first black belt and counted him among the best coaches and original thinkers of his time. SBG describes Thornton as the first Brazilian jiu-jitsu black belt in Oregon. Seminars, tapes and Dublin Thornton began teaching seminars in 1995, when the savate instructor Daniel Duby asked him to fly to Réunion. SBG says Duby in turn brought a savate influence into its training. By SBG's count Thornton has since taught more than four hundred seminars, in countries ranging from France, Denmark and Sweden to Iceland, Mexico, Chile and the Seychelles, and it credits him with first bringing Brazilian jiu-jitsu to Réunion and to Iceland. Adam and Rory Singer, of the Hardcore Gym in Athens, Georgia, adopted his methods after coming across the Functional JKD VHS tapes. Adam Singer joined SBG and used the methods in coaching his brother Rory and Forrest Griffin, both of whom fought in the UFC, and SBG credits the Singers with taking Griffin from white belt to UFC light heavyweight champion. Other gyms followed and flew Thornton around the world to teach aliveness and ways of training rather than techniques. In November 2001 he was cornering a team in South Africa that included Rory Singer and Forrest Griffin at a Pride and Honor event outside Johannesburg. One of his fighters faced John Kavanagh, an Irishman who had traveled alone, without a cornerman, and Kavanagh lost. Thornton was impressed by him and gave him a private lesson, and the two stayed in touch. Kavanagh visited SBG in Oregon, and Thornton flew to Dublin, where Kavanagh was teaching in what Thornton called literally a shack. Kavanagh has written that Thornton was the first person to assess his grappling. In 2002 Thornton gave him a purple belt, and Kavanagh renamed his gym SBG Ireland. Fightland reported that Thornton's advice to him throughout was simply to do what he loved. Thornton promoted Kavanagh to black belt in February 2007, during a visit to Dublin. His first black belt had gone to Luis Gutierrez in 2005, and Karl Tanswell, a coach in the UK, became the third in July 2007. BJJ Heroes calls Kavanagh the first black belt in the Republic of Ireland. In a note after the promotion, Thornton praised Kavanagh's technical finesse and his grasp of why the art works, which he expected would let Kavanagh pass it on. Thornton, who had known McGregor since McGregor was a boy, credits Kavanagh with an environment that kept the focus on fundamentals while leaving athletes free to develop their own style, the setting in which, as he sees it, McGregor built his unorthodox way of moving. A growing network In 2001 the affiliated gyms that had grown up since the late 1990s were brought together in a formal body, the SBG International Brazilian Jiu Jitsu Association. A 2004 profile listed branches across the US and in England, Ireland, Denmark and South Africa. In 2012 Portland Monthly put the number of affiliated gyms and training groups at 15 in the United States and 10 in other countries, among them Seoul, Cape Town and Dublin, and a 2023 podcast biography put SBG at more than seventy locations worldwide. Workshops became central to the business. Thornton told the Daily Inter Lake in 2018 that they let him see affiliate instructors, their schools and their students, and judge whether standards of ethics, safety and performance were being kept. Travis Davison, owner of SBG Montana and vice president of SBG International, described Thornton as his coach, mentor, friend and business partner, and credited him with teaching people to tell fundamentals from fluff. By SBG's fall camp in 2022, Thornton had awarded 38 black belts; he wrote in the January 2023 newsletter that the latest had gone to Jon Hobson. One of them, Lily Pagle, began training with him at 50. She became his seventh black belt and his first female black belt, and at 61, during her promotion, she took on every higher-ranked belt in the room. In 2004 he told MMA.IS that SBG was meant for everyone, not only young competitors, and asked why a 53-year-old woman should not train if she enjoyed it. In the same interview, somewhat to the writer's surprise, he said he was not especially keen on MMA as entertainment and called it barbaric in a sense, because boxing and MMA cause brain damage. Later work His connection with Rickson Gracie has continued. SBG Portland says that when Rickson returned to teaching seminars in 2016, SBG hosted the comeback seminar in Portland, Rickson was interviewed alongside Thornton, and SBG accepted his invitation to join his new Jiu Jitsu Global Federation, in Portland and at several other SBG gyms. In 2019 Thornton released Mastering the Mount, the first new instructional he had put out in 15 years: a series of 15 videos on drilling and developing mount skills, which SBG presents as the product of two years of coaching and seminars. In April 2023 Pitchstone Publishing brought out his book The Gift of Violence, a 400-page hardcover with a foreword by Robb Wolf and an afterword by Peter Boghossian. The publisher presents it as practical, evidence-based guidance for ordinary people on avoiding and surviving violent encounters, drawn from his decades of teaching self-defense, and Rickson Gracie's endorsement calls Thornton one of jiu-jitsu's most passionate ambassadors. That month Sam Harris released an episode of his Making Sense podcast with Thornton about the book, covering his martial arts background, what the episode calls the street-versus-sport fallacy, the persistence of fake martial arts and Bruce Lee's legacy.

    • In an interview on his own site, Thornton said that a couple of years after he started boxing he met Brazilian jiu-jitsu black belt Fábio Santos, who introduced him to the art; being effortlessly tapped out with a triangle choke felt like magic, and this was before MMA or the first UFC. After major disagreements with the school where he taught, he opened his own club about forty miles south so as not to compete directly with it, sharing a very small space with a friend who was a judo black belt.

    • Thornton told the Daily Inter Lake in 2018 that he became disillusioned with JKD, feeling its message had been lost behind the scenes and that he could not teach something he did not think was real; he then crossed paths with Fábio Santos, then Rickson Gracie, and opened the first Straight Blast Gym. The name nods to his JKD roots — the straight blast was one of Bruce Lee's signature moves — and he chose 'gym' rather than academy or institute so people would know it was a place to work out and sweat.
