The story behind the fascia-first system
The story behind the fascia-first system
At 15, I developed knee pain. An MRI revealed a bony growth in my left knee, something structural which was affecting how my body organised and transferred load. What stood out wasn’t just the diagnosis. It was the approach. Everything focused on the knee in isolation. A localised problem with a localised solution. It didn’t make sense. That experience stayed with me. It led me to study the human body in more depth, graduating in 2017 with a degree in Podiatric Medicine and going on to work across both the NHS and private clinical practice. But even as my clinical understanding developed, I kept seeing the same pattern across athletes, professionals, and high-performing individuals.
Symptoms were being chased.
The system was being missed.
This became even clearer through my own training into my late teens. As a British and Commonwealth kickboxing champion, I was training 5/6 times a week, often twice a day. Under that level of demand, it was obvious: The body doesn’t operate in isolation. If one area wasn’t functioning well, something else compensated. You couldn’t treat one part and expect everything else to hold. The system had to work together. However, most treatment models didn’t reflect that. So my focus shifted. Not to chasing symptoms, but to understanding how the body organises itself under load. How different regions influence each other, and how the fascial system, drives movement and long-term function.
The work of Thomas Myers helped frame that perspective, alongside early exposure to osteopathic principles through my elder brother. But understanding wasn’t enough. It had to work in practice. Through years of clinical practice, working with individuals who demand reliability from their bodies, I developed the Seventy3® system, a different approach to understanding the human body. One that looks at the body globally before locally and focuses on long-term function, not short-term relief. A fascia-first system designed to restore how the body organises, communicates and functions.

Hamayoon Kasser | Founder Seventy3
At 15, I developed persistent knee pain. An MRI revealed a bony growth in my left knee. What stood out wasn’t just the diagnosis, it was the approach. Everything focused on the knee in isolation. It didn’t make sense.As I moved into clinical practice, I saw the same pattern repeatedly.
Symptoms were being chased.
The system was being missed.
That became even clearer through my own training. As a British and Commonwealth junior kickboxing champion, training 5–6 times per week, the reality was simple: The body doesn’t work in parts. If one area breaks down, something else compensates.
Treating one area in isolation was never enough. Through years of clinical application , I developed a different approach. One that looks at the body globally before locally and focuses on long-term function. Seventy3® a fascia-first system designed to restore how the body organises, communicates and functions.
