The Coach
Dave
Marsh
Coach. Educator. Athlete.

I built Performuscle because I was tired of seeing people destroy their health in pursuit of aesthetics. True transformation only happens when your health, function, and performance all move forward together.

With 15 years of real-life coaching experience working with athletes, CEOs, high performers and everyday people, I've developed a system that delivers visible results without sacrificing your hormones, metabolism, or longevity. No crash diets. No junk volume. Just smart, sustainable progress.

The Foundation
Three Pillars
of Every Plan

Most coaches optimise for one thing. We build all three simultaneously — because they're inseparable.

01
Health

Metabolic health, hormonal balance, sleep quality, and longevity markers come first. If your health is declining, no amount of visible progress is worth it.

02
Function

Movement quality, mobility, and structural balance keep your body resilient. We train you to move well for life — not just to look good standing still.

03
Performance

Strength, muscle, body composition, and endurance. The metrics that get you in front of the mirror and drive every session. This is the output of the first two pillars done right.

30 Audit & Reset
60 Build & Adapt
90 Perform & Own

Imagine waking up full of energy, feeling ten years younger — mind clear, ready to perform. You've just come out of a deep sleep. The sun hasn't risen yet and you're ready to start your day with a programmed workout.

You're leaner, stronger, sharper — but most of all you feel a new sense of purpose. Instead of reacting to life, you move with intent and clarity. Present and ready to perform.

The 90 Day Human Reset is a complete overhaul of your physiology and psychology. We audit your sleep, nutrition, movement, stress, and recovery — then rebuild you from the ground up.

This isn't a crash course. It's a permanent upgrade.

Client Results
What They're
Saying
★★★★★

"I'd been to physios and chiros for over a year and couldn't fix my movement issues. In 12 weeks with Dave I went from a 20kg front squat in pain to 40kg pain free — and I'm now prepping for a half marathon PB."

Kara Gibbons
12 Weeks · Mum · Coach · Business Owner
★★★★★

"I've been training for over a decade and never looked or performed like this. 7 months in — 5.4kg of muscle added, leaner than ever, and hitting numbers I thought were years away."

Joe Robinson

★★★★★

"8 weeks, 5.8kg down, and I actually performed better in the gym throughout. No peptides, no gimmicks. Just Dave's process and showing up. First photoshoot is booked."
