Muscle Damage Theory
Micro-tears from training can support growth but excessive damage and soreness are poor progress markers—tension and recovery matter more.
Muscle damage theory treats microscopic fiber disruption—from novel eccentrics or long ranges—as one hypertrophy stimulus among others, not the sole goal. Excessive damage delays the next quality session and confuses soreness with progress.
Emphasize repeatable tension and proximity to failure over chasing DOMS.
Common questions
-
Is soreness required for muscle growth?
No—you can grow with minimal soreness when load and reps near failure progress. Persistent extreme soreness often signals too much novelty or volume.
