Zone 2 vs Tempo vs Threshold Training

Core Difference
These intensity zones differ by effort level, fatigue cost, and adaptation focus.

Zone 2
Low-to-moderate intensity supporting aerobic base and recovery.

Tempo
Moderately hard efforts improving sustained output and fatigue tolerance.

Threshold
High-intensity aerobic work raising performance ceilings.

Why the Difference Matters
Misclassifying intensity leads to excessive fatigue and poor adaptation.

Key Takeaway
Each zone serves a distinct purpose and must be applied deliberately.

What Is Training Load? | What Is Fatigue? | What Is Recovery?
