Behind the Practice
The Strength & Physiology Clinic was created through years of working with people who were motivated to look after their health, but lacked clarity on what truly mattered.
Across sport and general populations, Aaron observed the same pattern. People exercised regularly, yet key markers of physical capacity – cardiovascular fitness, strength, balance, and movement – were rarely assessed, clearly explained, or monitored over time. As a result, many people exercised consistently but without clear direction, lacked early insight into physical changes, or only addressed issues once symptoms became more noticeable.
The clinic was established to change that trajectory.
By assessing and developing the physical qualities most strongly associated with long-term health, resilience, and independence, The Strength & Physiology Clinic provides a proactive pathway. It helps individuals strengthen their physical capacity, reduce avoidable decline, and support their health before issues escalate into injury, illness, or medical intervention.
This is not about replacing healthcare, but complementing it – helping people stay stronger, more capable, and better equipped to remain well over time.
Our Story
The Team
Aaron parsley
FounderAaron is an exercise physiologist, strength and conditioning coach, with an extensive coaching background across sport, health, and fitness. As a research-based practitioner, he uses a scientific approach to assessment, monitoring, and coaching to help clients build long-term physical capacity, resilience, and confidence in their bodies.
Aaron graduated from St Mary’s University with degrees in Strength and Conditioning Science (BSc) and Applied Sport and Exercise Physiology (MSc). He has worked with Premier League footballers, Team GB Judo athletes, Team GB track athletes, and a wide range of highly competitive sports teams and individuals.
He now applies this refined skill set to a broader population, with a focus on preventative health — helping people maintain strength, fitness, and functional independence as they age.
Using physiological testing and movement analysis, Aaron designs individualised programmes that support both performance and long-term health. His approach prioritises building robust physical foundations — strength, cardiovascular fitness, and physical capacity — so clients can train with confidence and adapt safely over time.
Alongside his clinical and coaching work, Aaron has supported a wide range of individuals, including business leaders, executives, and public figures. He has also contributed to books and media publications focused on health, fitness, and human performance.
Filip’s passion for human performance started early through sport. Growing up, he competed and trained across kickboxing, MMA, taekwondo, gymnastics, tricking, parkour, football, handball, snowboarding, bouldering, and more. Over time, he realised that structured strength training was the one constant that improved everything — no matter the sport. From that point, the gym became the foundation of his approach to performance and resilience.
With 13 years of experience in the gym, Filip combines practical coaching with an evidence-based background in sport science. He began coaching online while serving in the military, and has since been fortunate enough to train world champion powerlifters, Norwegian champion powerlifters, and special forces — while also understanding what it takes to guide everyday people towards exceptional results.
Filip was also the youngest person in Norway to compete in a bodybuilding competition, bringing first-hand insight into disciplined training, body composition, and high-performance preparation.
“In order to perform at your highest level, you need more than motivation — you need a plan, the right training stimulus, and consistency. My job is to make that process clear, structured, and sustainable.”
“My mission is to help people perform at their best — in sport, in the gym, and in everyday life. My coaching is built on 13 years of training experience and a deep commitment to strength, performance, and long-term progress.”
