A clearer way to approach health
Frameworks and tools for thinking about health, performance, and testosterone as systems—designed for real life, not ideal conditions.
What Zoos is
Zoos is a practical framework for understanding health and performance in context.
It's not a program, protocol, or coaching service.
It doesn't promise specific outcomes.
Instead, it focuses on improving how decisions are made over time—by integrating physiology, behaviour, stress, and environment into a coherent system.
The problem
Most health advice is technically sound and practically fragile.
It assumes optimal sleep, unlimited time, consistent motivation, and low cognitive load. When those assumptions fail, so does the advice.
What's missing is not more information, but better ways of thinking, adapting, and prioritising under constraint.
The approach
Zoos treats health as a system.
It prioritises:
- → first principles over tactics
- → constraints over optimisation
- → patterns over prescriptions
Rather than telling you what to do, it helps you understand why things work, when they stop working, and how to adjust without starting over.
Areas of focus
Zoos primarily explores:
- → general health and physical capacity
- → training, recovery, and stress
- → hormones and energy regulation (with a focus on testosterone in men)
- → behaviour, feedback, and decision-making
Each area matters on its own. The real leverage comes from how they interact.
Outputs
The ideas behind Zoos are expressed through a small set of focused tools:
- → A systems-based book on general health
- → A practical exploration of maximising testosterone effect
- → A software tool to support behaviour change, signal tracking, and decision-making
Each can be used independently. Together, they form a coherent approach.
Orientation, not optimisation
Zoos is not about winning fitness.
It's about building a body and mind that support a demanding, interesting, and sustainable life—without requiring obsession, identity, or constant optimisation.
The goal is not perfection.
It's direction.
