I did not get into training to look better. I got into it because by my late thirties, the second half of my working day had quietly become useless. The hard architectural thinking — the kind that needs four uninterrupted hours — was happening less and less, and I had been blaming meetings. The meetings were real. So was the fact that I had let my physical capacity decay to the point where my brain ran out of runway by 2pm.
- 01 Treat aerobic base + sleep as infrastructure for cognition, not vanity.
- 02 Zone 2 cardio is the unglamorous, high-leverage lever for sustained focus.
- 03 Strength twice a week protects the desk-bound body from its own posture.
- 04 Track inputs (sleep, training, steps) — not the scale. The scale is a lagging, noisy metric.
The reframe: capacity, not aesthetics
A focused engineering session is metabolically expensive. If your aerobic base is poor and your sleep is fragmented, you are trying to run a demanding process on a starved power supply. Aesthetics are a side effect. The actual deliverable is afternoons that still work.
The protocol
It is deliberately boring. Boring is what survives a launch week.

NON-NEGOTIABLE: 7.5h sleep opportunity. Everything above is downstream of this.Zone 2 is the lever nobody posts about
Most of the focus benefit, for me, came from unsexy low-intensity cardio. It builds the aerobic base that lets the brain sustain effort without the mid- afternoon crash. It is also the easiest thing to keep during a stressful sprint, because it does not wreck you for the next day.
Strength protects the substrate
Two strength sessions a week are insurance against the specific damage of a desk: weak posterior chain, locked hips, a neck that has been craning at a monitor since 2009. You are not chasing a number. You are keeping the hardware serviceable.
What I track, and what I ignore
I track the inputs — sleep hours, training sessions completed, daily steps — because those are the levers I actually control. Outcomes follow inputs with a lag. The same is true of any system worth operating: you instrument the causes, not just the symptoms.
The honest summary: this is not a transformation story with an inspiring photo. It is a maintenance contract I signed with my future self, so that the work I care about still has somewhere to run.
