Meet Your Coach
I'm Dave Marsh
I'm an elite performance coach with 15 years of experience working with athletes, executives and high-achievers. I built Performuscle because I know what it's like to be held back by a body that won't cooperate. I've rebuilt my own body from burnout to where I am today.
My approach goes beyond training and nutrition. I look at the whole human: movement, health, function and performance. So you don't just look better, you perform at your absolute best in every area of life.

Biomechanics, Body Recomposition & Athletic Performance
Pain-to-performance methodology. From chronic pain to elite function
We start with a full Performance Audit — assessing your movement, body composition, nutrition and lifestyle. From there I build you a fully customised programme and we meet weekly to review progress, adjust the plan and keep you accountable. You get direct access to me throughout.
Most clients notice improvements in energy, movement quality and performance within the first 2–3 weeks. Visible body composition changes typically show within 6–8 weeks when you follow the programme consistently. The 90-day mark is where the real transformation happens.
Most programmes give you a template and leave you to it. I treat every client as an individual. We start by finding out exactly what's holding you back — whether that's poor movement, nutrition gaps, sleep issues or past injuries — and address the root cause. This isn't a cookie-cutter plan.
Not at all. I work with athletes, executives and everyday high-achievers at all fitness levels. Whether you're coming back from injury, starting fresh or looking to take your performance to the next level — the system meets you where you are.
This is where I specialise. The Pain to Performance methodology was built for people held back by injury and dysfunction. We restore movement quality first, then build performance on top of a solid foundation.
