For nearly two decades, I’ve been helping people build stronger bodies, sharper minds, and live healthier lives. As Linford Christie's son, I grew up understanding how a healthy, active lifestyle can have positive effects on both the body and the mind.
I qualified as a Personal Trainer in 2007, and since then I’ve built a career on one simple belief: when you understand your body, you can change your life.
My expertise goes far beyond traditional PT. I hold specialist certifications in Children’s Fitness and Menopause & Exercise, giving me the tools to coach with precision across different life stages. As a Level 5 Nutritionist and Level 5 Fitness Life Coach, I bring a deeper understanding of behaviour, mindset, and the science of change. Training with me isn’t just about reps — it’s about building habits, confidence, and resilience that last.
Within MBMCo, I also run a clinical arm of my work as a Sports Massage Therapist. This gives me a unique advantage: I don’t just train bodies, I understand them. I know how they move, how they break down, and how to bring them back stronger.
Whether you’re in my mixed HIIT circuit, my women’s strength class, or on the treatment table, you’re getting a coach who sees the full picture — performance, recovery, and everything in between.
Founded in 2021, MBMCo (Motivated by Merrick Christie-Osborne) is the result of years of learning, coaching, and refining what truly works — not trends, not shortcuts, but real, sustainable progress.
MBMCo isn’t just a brand. It’s the standard I hold myself to: motivated, knowledgeable, and committed to helping every client become the strongest version of themselves. If you’re ready to train with purpose, learn with clarity, and push past your limits, you’re in the right place.
