Everyday activities do NOT produce significant muscle growth because:
A. Cytokines are released during everyday activities that inhibit (prevent) muscle regeneration.
B. Muscle growth requires going to the gym and lifting weights.
C. The nervous system cannot respond by recruiting more muscle fibers to generate hypertrophy.
D. The body adapts to the repeated demands so that those movements do not produce enough stress to cause hypertrophy (enlarging of the muscle).
