Why I started

As a desk-bound solo dev, I treat training as another form of building in public — logged daily to stay honest.

💡 Core principle: consistency beats intensity. Build the habit first.

My plan

Three strength + two running sessions a week. Here is the snippet I use to generate the calendar:

const plan = week.map((d) => ({ day: d, type: rotate(d) }))

Gear & tools

What I actually use: Garmin Forerunner 265affiliate link and Nike Pegasus 41affiliate link.

  1. A fixed time slot matters most
  2. Logging itself is motivation
  3. Sleep beats supplements
  4. Don't chase the perfect week
  5. Strength work makes running steadier
  6. Public check-ins lower the odds of quitting
  7. Body metrics deserve tracking, just like product metrics
