Complete Guide to Heart Rate Training
Confused by heart rate zones? Wondering why your heart rate always feels too high — or why “Zone 2” never makes sense?
This step-by-step guide will teach you exactly how to start heart rate training the right way, so you can run smarter, stay injury-free, and finally see progress.
What’s Inside:
-
✅ Clear explanation of what heart rate training is (and why it works better than training by pace)
-
✅ Step-by-step instructions to calculate your max heart rate, threshold, and training zones
-
✅ The truth about Zone 2 running (and why zones are often mislabeled)
-
✅ How to stay at the right effort for every run
-
✅ What to expect when you start (why it feels slow at first, and how to stay consistent)
-
✅ My favorite gear recommendations (Garmin, Apple Watch, HR straps)
Why This Guide Works:
Most runners train too hard on easy days and too easy on hard days. This guide shows you how to balance intensity, build consistency, and recover faster — so you can stack weeks of quality training without burning out.
