Protein intake plays a crucial role in muscle recovery by repairing and rebuilding muscle fibers damaged during exercise. Consuming protein-rich foods or supplements shortly after a workout can enhance the muscle's repair process and promote optimal recovery. Aim for a combination of protein sources, such as lean meats, dairy, legumes, and nuts, for a well-rounded intake. Sufficient protein can also help to reduce muscle soreness and support overall strength gains, leading to improved performance in subsequent workouts.
