- Three ways to find your Zone 2 HR — talk test (free), formula, and lactate test (if you want precision). Fillable box: my zone is ____ to ____.
- 28-day calendar, built like a habit loop — starts at 20 minutes. Scales to 60. Every session is specified.
- Progress tracking that matters — weekly log + the single "you're improving" signal to watch for (same pace, lower HR).
Your 5-page training plan + Google Sheets log, in your inbox.
