Oscar Trelles

I build human systems that hold up under pressure.

I work with leaders, founders, and operators who are performing well on paper while quietly accumulating cognitive load, physiological debt, and decision fatigue. The work is not motivation. It is regulation, constraints, and environment design.

Start here

The Human OS Manual

The conceptual spine. A practical model for how inputs, state, patterns, and environment shape performance and health across time.

Unblocked in Ten Weeks

A contained intervention for high-pressure operators who need steadiness, clear thinking, and a return to internal coherence.

The Reverse Aging Challenge

A live immersion where breath, cold, heat, fasting, movement, and community are used as a controlled environment for durable change.

Field notes

I publish long-form essays and short-form notes. The manual holds the definitions. The essays hold the edge cases and lived experience.
