Muscle gain refers to the process of increasing the size and strength of skeletal muscles through physical activity, particularly resistance training. This occurs when the muscle fibers experience small tears during exercise, which then repair and grow back stronger and larger during recovery. Proper nutrition, especially adequate protein intake, plays a crucial role in supporting this process. To effectively achieve muscle gain, individuals often follow structured workout programs that include exercises like weightlifting and bodyweight movements. Consistency in training, along with sufficient rest and recovery, is essential for optimal results. Additionally, tracking progress can help individuals stay motivated and make necessary adjustments to their routines.
