Trojan Workout

In the world of modern fitness, where the norm is to over-promise and under-deliver, the Trojan Workout is the complete opposite: the Trojan Workout has been used by elite martial artists for a decade. That the Trojan Workout works is beyond dispute, the only variable is the adherence of the user.

I created the Trojan workout as a way for elite Krav Maga fighters to “up their game,” the same dramatic benefits experienced by elite fighters can also be obtained by regular people from all walks of life – how is this possible? Both the elite athlete and beginner use the identical training template -what modulates are the payloads.

The Trojan Workouts strengthens the body and in turn, strengthens the Mind. Strength is the preeminent bio-motor attribute (speed, strength, endurance, flexibility, agility) and the Trojan Workout was designed to strengthen body and mind in the shortest possible timeframe.

Become a certified instructor and be part of a mission. You can help ordinary people obtain extraordinary results by becoming a certified Trojan Workout instructor. You will become part of a method that empowers others all over the world. Trojan Workout instructors will teach people how to train, how to challenge themselves and how to grow stronger, mentally, physically and spiritually.


Dragon Door Publications and Paul Wade present an opportunity for trainers and bodyweight exercise enthusiasts worldwide to plunge deep into the Convict Conditioning oeuvre, with the Progressive Calisthenics Certification Workshop—to both master the progressions personally and be qualified to teach them to others.

If there is a white-hot trend in fitness right now, it’s bodyweight strength training. Athletes of all kinds are looking to the toughest, most brutally productive calisthenics techniques to spice up their workouts. We’re talking one-arm push-ups, pistols, pull-ups, handstands and hanging levers!

Sadly there has been no international industry standard for bodyweight strength training instruction.

…until now.

Dragon Door introduces bodyweight strength authority, Al Kavadlo (CSCS, PCC Master Instructor), with Danny Kavadlo (PCC Master Instructor) to lead the PCC: Progressive Calisthenics Certification.

The PCC workshop is held once every 2 years in Haarlem, The Netherlands


Since Dragon Door launched the modern kettlebell movement in 2001, this amazing “gym-in-the-palm-of-your-hand” has redefined the fitness landscape on a global level, liberating hundreds of thousands from the limitations and frustrations of machine-based workouts.

Dragon Door challenges the tyranny of rigid thinking and of outmoded ideas about how best to cultivate yourself physically. We free you to achieve your full athletic potential by offering you the most effective, results-producing strength and health programs on the planet. We create equipment and systems like the RKC that free you from the wasted effort and time associated with the traditional gyms and health clubs.
The ultimate tool for independently-minded individuals looking to take charge of their own health and strength is the kettlebell. The kettlebell gives you more health, strength and conditioning benefits than you’ll get from a whole facility full of equipment.

Kettlebells still lead the charge for a high-impact, high-yield device that has just one purpose in mind: to free you from any hint of weakness—and allow you to move with dynamic power and long-lasting strength.
And the RKC instructional SYSTEM remains the leader when it comes delivering you the most efficient, cost-effective and thorough education in how to become a skilled kettlebell trainer. And become a trainer who gets consistently exceptional results for their clients, be it in weight management, athletic performance, foundational strength—or building a superb physique, at any age.

In fact, coaches, trainers and health professionals of all kinds have been quick to take advantage of the kettlebells’ almost magical ability to reduce unwanted fat, restore lost function and rebuild lost strength and vitality…
Chiropractors, massage therapists, physical therapists, physicians, sports coaches, you name it, have also eagerly embraced the kettlebell’s uncanny ability to rehab injuries—in particular, back and shoulder injuries.
Athletic coaches at the school and professional level have seen their athletes gain an obvious competitive advantage through proper kettlebell training.

The police and military—whose very lives can depend on their physical strength and conditioning levels —have welcomed kettlebells as a high-yield, simple, portable tool for fast and permanent strength, power and cardio gains.

The RKC workshop is held once a year in Haarlem, The Netherlands

What Others Say

There is no doubt that the methods of the Trojan Workout are the best practice methods for those who seek fitness and strength, integrated with realistic experiences, and these are the motifs I was glad to find in this book. It is also a wonderful way to expend the knowledge of Krav Maga, as it was founded by IMI and continues to grow and improve by the new creative and gifted minds of this generation.

What Others Say

At this phase of my life and career, I don’t need to do anything. I only take on projects that interest or excite me. When John DuCane put me in touch with Martijn, I had an immediate connection. He was onto something powerful. I really liked his credentials. He’d had a hell of a life for a young man. He really won me over when, after working on the book project for a month he let slip in his typical low-key fashion that he’d been a featured cast member on a hit European reality TV show – replete with scandal and intrigue – add to that some of drills he had to pass to win his level 14 Krav Maga certification and I was knew I wanted to do his book – it wrote itself – from start to finish six-months and done!
