How to Train by Heart Rate Zones (And Why You Should)

If you're training hard but not getting faster, chances are you're stuck in the “meh zone”—not easy enough for recovery, not hard enough to improve performance.

Heart rate training fixes that. By working in targeted zones, you can train smarter, recover better, and make every session count. Whether you’re chasing endurance, speed, or hybrid performance, knowing your heart rate zones gives you the roadmap.

Use our Training Zone Calculator to find your personal heart rate zones based on your age or max heart rate.

Why Use Heart Rate Zones?

Heart rate zones help you train with purpose. Instead of guessing how hard you're working, you train based on actual physiological effort.

Each zone corresponds to a different training benefit:

• 🟢 Zone 1 (50–60% HR max): Active recovery, low-intensity movement
• 🟡 Zone 2 (60–70% HR max): Aerobic endurance, fat burning, long easy efforts
• 🟠 Zone 3 (70–80% HR max): Tempo work, steady state fitness building
• 🔴 Zone 4 (80–90% HR max): Threshold training, lactate tolerance
• 🚀 Zone 5 (90–100% HR max): VO₂ max, short intense intervals

Training in all zones (at the right time) helps build a complete athlete—one who can go long, go hard, and recover fast.

How to Calculate Your Heart Rate Zones

You have two options:

1. Basic method: Use the formula 220 – age to estimate your max heart rate
2. Advanced method: Enter your known max heart rate (from a recent test or wearable)

Our calculator does the rest—spitting out your personalized Zone 1 through Zone 5 heart rate ranges in beats per minute (bpm).

Training Zone Tips by Goal

• 🏃 Endurance Athletes: Spend 70–80% of your time in Zone 2. Sprinkle in Zone 3–4 for race prep.
• 🏋️ Hybrid Athletes: Mix Zone 2 aerobic work with Zone 4–5 intervals to improve both systems.
• 🚴 Cyclists / Triathletes: Use Zone 3–4 for tempo rides, Zone 5 for short high-intensity bursts.

The biggest mistake? Doing everything in Zone 3—hard enough to tire you, not hard enough to improve you.

How Often Should You Recalculate Zones?

If you’re new to heart rate training, recalculate every few months or after a fitness breakthrough (like a race PR). As your aerobic engine improves, so will your heart rate response.

More advanced athletes may want to use lactate threshold or HRV-based zones for precision—but this calculator is the perfect starting point for most people.
