Tell me when and how hard to train today

A runner's watch syncs while he sleeps; an app he wrote moves yesterday's Garmin data into Notion, and an AI morning brief weighs his sleep, HRV, training status, calendar, and weather to tell him when to work out that day - and how hard.

How it works

  1. Watch syncs after waking
  2. Yesterday's Garmin data lands in Notion
  3. The AI compares sleep, HRV, training status, calendar, and weather
  4. Brief states when to work out and at what intensity

Why it’s worth knowing

The brief doesn't summarize his stats - it makes the decision: five data sources collapse into 'train at 6, keep it easy' before he's out of bed.
