Training Tool
Heart Rate Zones by Goal
Convert your max heart rate into practical training zones for easy session planning.
What this tool does
Transforms one number (max HR) into 5 effort zones so you can match workouts to your goal: recovery, endurance, threshold, or high intensity.
Who and when to use it
- Runners, cyclists, and gym users using a watch or chest strap.
- Anyone rebuilding training structure after inconsistent periods.
- People who want objective pacing instead of guessing effort.
How to use
- Enter your max heart rate (from test or estimate).
- Generate zones and save them in your watch app.
- Use Z2 for base work, Z4-Z5 for hard intervals, and Z1 for easy recovery.
Example interpretation
If Z2 is 120-140 bpm, keep easy cardio there. If your “easy run” keeps drifting above 145 bpm, slow down to protect recovery quality.
FAQ
Can I estimate max HR from age?
Yes, but measured max HR is usually better when available.
Do zones differ by sport?
They can. Running and cycling values may vary slightly for the same person.
Do I need a chest strap?
Not always, but chest straps are typically more accurate for intervals.
Should every session target high zones?
No. Most progress comes from consistency and enough low-intensity volume.
