Founder of PrimalThenics

Chris Miller

Chris Miller has spent over 20 years turning pain, injury and dysfunction into strength, resilience and long-term performance. A registered Doctor of Traditional Chinese Medicine with deep roots in rehabilitation, elite sport and applied neuroscience, he ran his own sports-injury practice for 15 years and holds postgraduate training in Functional Neurology, Medical Neuroscience and Sports Nutrition.

Coaching since 1997, Chris has worked across six Olympic and Commonwealth Games and with elite teams including the QLD Reds, Brisbane Broncos, Australian Wallabies and Western Force. He currently leads science and product research for Hydra Longevity and is one of only a handful of Master Trainers worldwide for Exxentric Flywheels — the sole licensed Exxentric educator in Australia.

He's the founder of PrimalThenics, a bodyweight system blending clinical rehab, neuromuscular re-education and primal movement delivered worldwide through the PrimalThenics App, and creator of LeanSuits Fitness, an EMS model delivering real results in just 20 minutes.

Having come back from three knee reconstructions and a sinus tumour with neurological complications, Chris brings rare first-hand insight into recovery and resilience. Away from the studio, he's a devoted husband and full-time stay-at-home dad.

PrimalThenics Team

Nathan Tomarchio

Senior Coach

Nathan is an accredited Exercise Physiologist with over 10 years in allied health and fitness. He works alongside founder Chris to deliver youth and adult programs, run land-based training for the Newmarket Racers National Swim Squad, and coach individuals one-on-one to address the root causes of their health and performance.

With the team for over three years, Nathan was drawn to PrimalThenics for its unique blend of Eastern medicine, neural engagement, mobility, animal flow, and innovative strength and conditioning — including Exxentric flywheels and K-boxes. His one-on-one work is built on his Exercise Physiology background and CHEK Institute training (Holistic Lifestyle Coaching and Integrative Movement Science), helping clients build strong health foundations, reduce physiological load, and do more of what they love.

Nathan is also Head Exercise Physiologist at The Foot Collective, an international leader in foot restoration and play-based movement, and has trained in the WECK Method's rotational movement work. Grounded, playful and curious, he brings a coaching style all his own to the studio.

Lauren Hogg
Coach

Lauren has a passion for movement and sport, with a background in elite competition swimming.

In 2024, Lauren completed her 200hr Yoga Teacher Certification and now facilitates the Primal Yoga at the studio.

Throughout her swimming career, Lauren enjoyed yoga as a form of recovery and enhancement on her training. She found it assisted with her mental focus, balance and preparation for competitions.

Without meaning to, she became a more well-rounded athlete both in the gym and in the pool due to her improved body-awareness and strength.

She loves the blend of quiet focus and challenging movements that Primal Yoga provides and is committed to helping people feel stronger, more mobile and confident in their ability.
