Robert Joyce

Osteopath (London, UK)

"This course is hands down the most in-depth course I’ve done since my 5-year degree. The amount we’ve covered over the weeks is immense but I never felt overwhelmed due to the support I’ve received and the logic of the teaching process. Overall I’m now a much more confident coach and therapist and have picked up several new clients as a result. Cannot recommend enough there’s nothing like this in the flexibility sphere."

Graham Anderson

Ninjutsu & Flexibility Instructor (Utah, USA)

"The Master Flexibility Trainer course is a massive game changer. Brilliant, impactful, and meaningful instruction that I have been able to put to use straight away with clients in my coaching business. Thank you!"

Asuka Sokabe, PhD

Sports Scientist & Kickboxer (Tokyo, Japan)

"Joining the course is the best investment in education I've ever made. I've taken every flexibility and "mobility" course there is, and nothing even comes close to this course's level of detail and no instructors match Dan's ability to make all the complex things very easy to understand. Dan is arguably the brightest mind in the field of flexibility training, but he's also a really nice guy who is clearly dedicated to his students."

Flexibility is the key to everything you want to do with your body.  Understanding flexibility and how to train it effectively and efficiently will empower you to help other people move and control their bodies.

Melissa Eleni

Flexibility & Pilates Coach

"I'm so happy I signed up to the Master Flexibility Trainer course! I wanted to dive deep into the science behind flexibility training and it's even better than I could have hoped for! Dan is able to concisely explain very complex concepts while giving you the tools to implement things into your own training and coaching. The course covers extremely extensive materials, while building upon knowledge each week. Dan's an amazing mentor and an amazing human, super respectful in his apprach to education and I feel very lucky to learn from him! The community of diverse professionals Dan is building is amazing and I've loved connecting with the others on the course and learning from each other! Can't wait for this community to grow :)"

AndreŐĀs Lippai

Callisthenics & Flexibility Coach

"In a world where there is tons of contradictions and mysticism around Flexibility Training, I found myself getting confused. Trying everything and getting some average results, but never really understanding what is happening. Dan helped me develop critical thinking, how to properly judge information and he pointed out everything that research has found to be effective (or not!) until now. Enrolling on this course was definitely one of my best decisions of 2020. I can see the whole picture more clearer than ever, I'm feeling more confident to teach Flexibility and I'm getting some massive gains myself. The best thing from the course is how Dan can explain to you very complex concepts in 30 minutes lessons and in a simple manner, making me feel calm as everything starts to make sense. Can't thank Dan enough for all the hard work he puts in. If you get into the course you'll know what I'm talking about."

Dr Jessica Davis

Clinical Psychologist & Researcher (San Diego, USA)

"I had the pleasure of learning from Dan at several of his in-person flexibility seminars when I competitively figure skated. His ability to teach complex topics in a conversational tone with simple words is what sets him apart from other instructors. That, and he seems to be able to answer any question on flexibility with considerable ease and insight! The level of attention to detail on the course is mindblowing, and the amount of care Dan puts into his responses on the forum is a sign of how much he loves this subject and cares for his students. This course has been one of the best educational experiences of my life."


99% of the industry is wrong about flexibility - learn why


No other programme or system has ever covered the subject of flexibility training as thoroughly as the Master Flexibility Trainer course.

Tanja NinicŐĀ

Flexibility & Callisthenics Coach

"Coming from a biology background, I can now finally connect the void between the theory and real life experience. I feel like most people who teaches coaches, either lack the scientific background or they are too nerdy and don't know how it is to practice in real life. So what I like with Dan is, that he practiced for many years himself and knows that not everything is linear and exact when you actually practice something, but he also has the scientific base. This is why I feel that I can finally connect the dots. I knew from my biology studies about the anatomy, physiology, biochemistry. And I knew from being a coach who practices what they preach about training. This course helped me find a new purpose from all the theoretical knowledge I had before. No BS, just science based information that is presented in a way that will make sense even for people who don't come from a natural sciences background. I do HAVE TO mention that on top of everything written above, he's also a very cool, approachable person. One of the things I like the most is that he's not dogmatic and always open to changing his mind, as long as the evidence supports a new theory. This makes me feel like I'm learning based on facts and I'm not just part of some cult, like it can feel a lot of times nowadays in this industry. All in all, this was the best purchase of 2020 and I'm grateful to be part of the first students of this course."

Ken Chow

Researcher & Trainer (New York, USA)

"Dan, just a quick message with feedback about the course. It's brilliant. I'd even say it's probably the best course I've ever done. I was sceptical about flexibility because I've only ever been told it's passive and therefore useless. Now I realize how short-sighted that mindset was. I wish you had been the presenter on my biochem masters and when I took my CSCS. Compared to you, those teachers had zero personality or understanding of how to communicate with human beings. Keep up the great work and I can't wait to finish the course. Thank you man."

Katie Taylor

Student (Birmingham, UK)

"The master flexibility trainer course is amazing! I'm currently on module 3 and the course has opened my eyes so much. I had to watch some lessons a few times to truly understand the content, but that was because I'm completely new to anything related to training or the human body. The way Dan explains things is brilliant. I haven't been able to get on any of the group calls yet because of family commitments, but being able to watch them back is priceless. Dan doesn't shy away from any questions and always checks to see if the answer he gave was the answer the person was looking for. I've been on training in the past (not fitness related) and the teacher would answer the question and move on without checking if the student understood. It's easy to recognise a good teacher and Dan is definitely one of the best! This course has also given me a way out of the depression of the pandemic. I worked in retail for 18 years until last year, then Covid hit and I found myself unemployed for the first time in my entire adult life. To cut a long story short, I've always had an interest in health and thought about getting into training other people, but I was always too scared. Thanks to Dan and the course I'm now getting the confidence to finally chase that dream!"

Dan Van Zandt is the world's foremost teacher in the science of flexibility and stretching. Since 1998, he has been coaching evidence-based flexibility training in the real world and online (longer than any other coach in the online space), and he has become widely regarded as the Internet's no.1 fact-checker on claims made about flexibility and stretching.

Having graduated with a bachelor's and master's degrees (both with full honours) in Kinesiology (the science of human movement) - specialising in sport and exercise biomechanics - his current PhD studies are in the neurobiology and neuromechanics of stretching. Other credentials include Certified Strength and Conditioning Specialist (with Distinction) from the NSCA, certified personal trainer, 200H yoga teacher, and sports therapist.

Dan began studying the art and science of stretching over 35 years ago when he started training in martial arts. To date, he holds black belts in six different disciplines. As an athlete he won gold medals at the World Games, European Championships, and 10 national championships in Taekwondo. He won 3 world championships in full-contact karate and was the head strength and conditioning coach with the England Karate Team for 5 years. He won multiple international coaching awards during that time.

During an extensive teaching career, Dan has delivered lectures on the biomechanics, neurophysiology, and psychology of flexibility and stretching worldwide. He created the Biomechanical Model of Flexibility, which was the world's first physics-based approach to flexibility training. He has taught teams of physical therapists and sports medicine practitioners at some of the world's most prestigious dance companies including Berlin State Ballet, American Ballet Theatre, Paris Opera Ballet, and English National Ballet. He has delivered lectures to undergraduate and postgraduate students at universities around the world including University of Zurich, Humboldt University of Berlin, and University College London.
