Muscles grow through a cycle of stress, damage, and repair. When muscles are exposed to new, challenging workloads—such as resistance training—they experience microscopic fiber damage. The body responds to this stress by triggering an immune response and utilizing proper nutrition, including protein and amino acids, to repair and build stronger tissue. This process, known as hypertrophy, relies heavily on adequate rest and natural hormones, like testosterone, to ensure the body can effectively recover and adapt to increasing physical demands.
