Lesson Overview

2.29 – Why Some Muscles Grow and Others Lag: Some muscles respond fast while others grow slowly, and that is normal. Muscle growth depends on leverage, fiber type, activation skill, and how often a muscle is trained correctly. Stubborn muscles like calves, rear delts, and forearms often need more frequency and better angles. Many people think they hit these muscles, but the stronger surrounding muscles steal the work. Improving mind-muscle connection helps the target muscle actually do the job. Range of motion matters too because partial reps can skip the part of the movement where the muscle is strongest. Changing grip, stance, and bench angles can suddenly make a lagging muscle “turn on.” Recovery also matters because a muscle that never fully recovers will not grow even with more sets. This lesson teaches you to diagnose lagging muscles with honesty instead of just adding random volume. You learn how to match effort with correct mechanics so work becomes growth. When stubborn muscles finally respond, your physique becomes more balanced and your lifts become more stable. Fixing lags also reduces injury risk because the body stops relying on weak links. This is how you build a complete strong body, not just a few strong parts.
