   30 Years of Martial Arts, Community and Taking the Risk with Paul Busby

   Show notes In this special 30th-anniversary episode of Jiu Jitsu Fieldnotes, Callum sits down with Paul Busby to trace a lifetime spent in martial arts—and the story behind the community he built. Paul recalls discovering taekwondo through the films of Jean-Claude Van Damme, dedicating himself to kickboxing and travelling internationally to compete and train with some of the sport’s best-known fighters. He also shares the defining moments that changed the direction of his life: leaving a secure Ministry of Defense career, risking his house deposit to open a full-time martial arts gym and introducing Brazilian jiu-jitsu to the academy. The conversation explores sacrifice, competition, coaching and the importance of creating a welcoming place where people can train, build friendships and find support during difficult periods of their lives. There are also stretching machines, homemade “cat’s claws”, an ill-advised ninja costume and a reminder that martial artists have always been enormous nerds at heart. Most importantly, Paul reflects on the ripple effect created by 30 years of martial arts—from lifelong friendships and careers in coaching to the thousands of adults, children and families who have become part of the community. Jiu Jitsu Fieldnotes is hosted by Callum and produced by Damo.

   Jui Jitsu Fieldnotes #4 John Collins

   John Collins is a two-time Olympian rower who competed at Rio 2016 and Tokyo 2020. In this episode, he sits down with Callum at Roger Gracie Academy Marlow to talk about elite sport, identity, transition, and why he walked off the water after his last race and made a lunchtime jiu jitsu class the same morning. What we cover: John's path into rowing started at 15 with the Duke of Edinburgh award — he wasn't particularly athletic, couldn't run, couldn't catch, but someone told him he was good at it, and that was enough. From a club in Twickenham to Leander, national trials, and eventually two Olympic finals, John walks us through the full arc: the funding realities, the brutal training camps (170km a week on average, 500km in 12 days in Portugal), the wave that nearly capsized his boat in the Rio heat, the semi-final gamble that almost got them a medal, and the emotional cliff that followed. He's honest about the Tokyo cycle too — returning too soon after running 348 miles for the Metro Marathon Challenge, a difficult coaching relationship, injuries to key partners, and ultimately missing out on Paris qualification. Retirement came on June 3rd. He was training at RGA Marlow by lunchtime. Two years in, John reflects on what makes jiu jitsu so different from rowing: the unpredictability, the daily visible improvement, the way advanced practitioners get calmer while white belts come in swinging, and how getting folded up by someone half his size on his first session was exactly what sold him on it. He also talks fatherhood, the mental health side of life after elite sport, coaching a rowing club from scratch, and why he nearly took Bruce Dickinson into the Thames on a tandem bike. Topics covered: Finding rowing at 15 and being told he was good at it The Duke of Edinburgh to Henley to GB trials pipeline Funding, parental support, and the reality of athlete finances Training volume — 170km average weeks, Portugal camps, the 30-minute ergo test Rio 2016: the wave that moved their boat a full lane, the semi-final from hell, and fifth in the final The emotional rollercoaster of watching teammates become Olympic champions Going again for Tokyo, the Metro Marathon Challenge, and returning to training broken Coaching conflict and being sidelined in the Paris cycle Retiring and walking into a lunchtime BJJ class the same day The unpredictability of jiu jitsu vs. the single-movement precision of rowing White belt competition nerves and the universal fear of losing Elite athlete identity, mental health, and staying busy in transition Fatherhood at five months in and squeezing in doubles classes before work Ronnie O'Sullivan, the Eubanks, and dinner at Bruce Dickinson's house

   Jui Jitsu Fieldnotes #3 Chris Ong

   A village hall in Sheffield. Blue belts running the room. A law student who wasn’t sure where he fit. Fast forward twenty years and Ongy has lived a full arc: corporate sales burnout, a switch to no-gi sparked by aching fingers and EBI highlights, and a leg lock class that helped transform how our gym trains. What emerges isn’t a hype story about submissions—it’s a blueprint for learning, coaching, and staying on the mats for life. We dig into the details that actually keep you improving. Ongy breaks down why the great leap came from concepts over techniques—treat concepts as your operating system (frames, head position, hip lines, underhooks), then install techniques that match. We explore ecological and constraints-led drills, why study platforms like SubMeta accelerate skill, and how to split gi and no-gi games to protect your hands and joints without losing edge. From half guard and coyote mechanics to top pressure and when leg locks belong in your plan, this is practical, usable strategy. Beyond tactics, there’s the mental toolkit. Positive Intelligence gave Ongy a way to spot saboteurs and shift from frantic left-brain loops to calm, right-brain presence. Jiu-jitsu is presence on demand—you cannot doom-scroll in side control. We talk injuries, returning smart, and why hobbyists should follow what’s fun while coaches do the necessary hard drilling. We also tackle belts and identity: celebrate promotions, don’t become them. Competing at black belt revealed real gaps—seated guard, wrestle-ups, pace—that turned into a clear training plan instead of a story about nerves. If you care about leg lock evolution, no-gi strategy, concept-first learning, mental fitness, and how to train into your fifties and beyond, you’ll feel at home here. Stay for the small-world moments, the artist’s eye on the sport, and the honesty about burnout, community, and why defence ages well. If this resonates, follow the show, share it with a training partner, and leave a quick review so more curious grapplers can find us.

   Jui Jitsu Fieldnotes #2 Cat Malik

   Callum and Cat roll into the world of Brazilian Jiu-Jitsu – where sweaty grappling meets surgical precision. They dig into the physical realities of BJJ, how often you should be training (and how often you actually do), and the particular challenges women face on the mats. Cat talks through her journey from traditional Japanese Jiu-Jitsu into BJJ, sharing how it’s helped her navigate personal hurdles, find her people, and fall in love with the grind. Along the way, the conversation bounces between competition nerves, the mental chess match of grappling, and the simple joy of training with good humans. Cat also brings her day job into the mix, offering a behind-the-scenes look at sports injuries, recovery, and how being an orthopaedic surgeon shapes her approach to looking after her own body. With plenty of laughs, honest reflections, and shared enthusiasm for the sport, Callum and Cat explore how martial arts culture is changing – especially for women – and why an inclusive, supportive gym can make all the difference. It’s thoughtful, funny, and reassuringly human – whether you train every day or just like hearing smart people talk about hurting themselves in controlled environments.

   Jui Jitsu Fieldnotes #1 Vinny

   Stories from the Mats at Roger Gracie Academy Marlow. Introduction: In the world of martial arts, Brazilian Jiu-Jitsu (BJJ) stands out not only for its self-defense techniques but also for the community it fosters. In a recent podcast episode, host, Callum Medcraft and his friend Vin delve into their shared experiences and insights about starting Jiu-Jitsu later in life, the importance of camaraderie, and the transformative power of this sport. Section 1: Discovering Jiu-Jitsu Vin's journey into Jiu-Jitsu began at the age of 30, sparked by his previous kickboxing experience and a growing curiosity fueled by online discussions and podcasts. He recalls the moment he stepped into the gym, feeling a sense of familiarity and comfort, especially upon bumping into an old friend, Al. This serendipitous encounter highlights one of the unique aspects of Jiu-Jitsu—it brings together individuals from various backgrounds, creating a diverse and supportive community. Section 2: The Challenges of Teaching and Learning Marlow reflects on the awkwardness of teaching Jiu-Jitsu during the pandemic, where grappling was restricted. Despite the uncertainties, Vin's enthusiasm shone through, as he actively engaged with the material and asked questions—traits that many beginners often hesitate to exhibit. This eagerness to learn is crucial, as it not only benefits the individual but also enriches the learning environment for everyone involved. Vin emphasizes that even though he often felt lost during practice, he found joy in the process, which kept him hooked. Section 3: Balancing Life and Training As a tradesman with a physically demanding job, Vin shares how he manages to fit training into his busy schedule. He stresses the importance of accountability—having a training partner who motivates you to show up and enjoy the process. Vin's philosophy is simple: as long as he finds joy in training, he will continue to do it. This notion resonates with many who struggle to find motivation amidst the chaos of daily life. Section 4: The Shift to No-Gi Training As Vin transitioned to exclusively training in no-gi, he noted the benefits it brought to his body, especially concerning his lower back. He appreciates the dynamic nature of no-gi, where techniques often lead to scrambling and quick adjustments. While both gi and no-gi have their challenges, Vin feels more at ease without the grips that the gi provides, finding freedom in the movement. Section 5: Advice for Newcomers For those considering Jiu-Jitsu, Vin offers straightforward advice: just do it. He encourages potential practitioners to try it out and see if it resonates with them. The welcoming nature of Jiu-Jitsu means there is likely a community waiting to support newcomers, making it an excellent option for anyone looking to forge new friendships and enjoy physical activity. Takeaways The gym is a place with diverse people and backgrounds. Jiu-Jitsu can be a fun and engaging way to stay active. Training can foster accountability and friendships. Sobriety can be supported through engaging in positive activities like Jiu-Jitsu. It's important to find enjoyment in physical activities to maintain motivation. Jiu-Jitsu helps in building connections with others through shared experiences. The journey of learning Jiu-Jitsu is ongoing and never truly complete. Physical jobs can complement training in Jiu-Jitsu. Finding a supportive community is crucial for personal growth and recovery. Engaging in Jiu-Jitsu can provide a non-negotiable structure in life.
