Welcome to the True Core™ Self Mastery Courses - a revolutionary approach to overcoming serious health conditions, built on decades of clinical expertise and the science of human movement.
Every programme here is curated by Tom Rosier, a master of pattern recognition who has helped thousands reclaim their lives from pain, dysfunction, and misinformation.
Many people with chronic pain or serious health issues are told the wrong thing, or worse, never told what the “core” truly is. The True Core™ Method is different. It’s not just a set of exercises - it’s a proven system rooted in deep understanding of how the body works, how pain manifests, and how true change happens.

Every course gives you access to free online, anytime webinar which teaches you a great deal about the condition you are trying to live with. In these webinars you are taught everything you need to know so you are FULLY INFORMED before committing to the course.
Once you have completed the course you are then free to purchase the mini course and start your journey to recovery.
True Core™ was born from my passion for helping people and my frustration with traditional physiotherapy methods. I wanted to create something new—something that could truly transform lives by addressing the root causes of pain, movement dysfunction, and stress-related conditions.
II am completely obsessed with human movement and how to enhance the awareness of my clients' physical capabilities.
Expect to learn some incredible new insights into your body, your health and fitness. I will assess everything from how well you move, how well you can control individual muscles and even address disturbances in your vagal tone.

Unlike conventional approaches, True Core™ combines cutting-edge science with practical techniques to rewire how the body moves. It’s not just about treating symptoms—it’s about creating lasting change through education, awareness, and movement mastery.
One of the most rewarding moments for me is seeing clients experience that first spark of connection to their core. It’s a profound shift - a realisation that their body can move differently, more efficiently, and with greater control.
Stress is often the hidden culprit behind chronic pain, postural issues, and even conditions like IBS, reflux, and urinary incontinence. True Core™ tackles these challenges head-on, helping clients recalibrate their nervous systems and restore balance to their bodies
At the heart of True Core™ is education. I believe that understanding your anatomy, how your body moves, and how stress impacts you is the key to long-term health. My goal is to empower every client with this knowledge.
True Core™ isn’t a quick fix if you are in pain. It’s a method designed to rewire your movement patterns for control, efficiency, and longevity. Whether you’re an athlete or someone recovering from chronic pain, this approach ensures sustainable results.
True Core™ goes beyond teaching movement - it builds confidence. Clients learn to create their own fitness programs, empowering them to take charge of their health and performance with independence and assurance.
True Core™ isn’t just about movement - it can enhance overall health. From improved posture and joint health to relief from stress-related conditions, this method delivers comprehensive benefits that enhance every aspect of life. For athletes its the cutting edge to your training, performance and competition.
True Core™ is more than a program; it’s a movement. It’s about empowering people to take control of their health, unlock their potential, and live with greater awareness and purpose. Let me help you discover the power of your True Core™.
