Definition
An increase in muscle-fiber size and overall muscle cross-sectional area. This term describes a training outcome or performance quality rather than a single workout style. Adaptation is influenced by progressive overload, total training dose, exercise specificity, nutrition, recovery and individual responsiveness.
Practical use
Judge progress with outcome-appropriate measures over weeks to months rather than by soreness or fatigue from one session.
