What Is Training Load?

Definition
Training load is the cumulative physical and physiological stress imposed on the body through training. It reflects both the work performed and the internal response to that work.

What It Includes
Training load includes external load (such as volume, intensity, duration, and frequency) and internal load (such as heart rate response, perceived exertion, and fatigue). Both dimensions are necessary to understand total stress.

What It Is Not
Training load is not simply how hard a workout feels or how much weight is lifted. High load can occur at low intensities if volume or density is excessive.

Why It Matters
Adaptation occurs in response to training load, but excessive or poorly managed load increases injury risk and impairs long-term progress.

Practical Implications
Effective training balances applied load with recovery capacity and adjusts load dynamically based on readiness and adaptation trends.
