Volume vs Intensity for Endurance Development

Core Difference
Volume refers to the total amount of work performed, while intensity reflects how hard that work is relative to maximum capacity.

Volume Emphasis
Higher volume supports aerobic base development, efficiency, and durability by allowing repeated submaximal exposure.

Intensity Emphasis
Higher intensity improves performance ceilings and race-specific capacity but carries higher fatigue and injury risk.

Why the Difference Matters
Overemphasis on intensity limits repeatability, while insufficient intensity caps performance progression.

Key Takeaway
Endurance development depends on volume for foundation and intensity for refinement—not one or the other.
