Protein is the essential macronutrient for muscle repair and growth after exercise. It provides the building blocks needed for muscle recovery and synthesis. Consuming protein post-workout supports the repair of damaged muscle fibers and promotes muscle hypertrophy. Aim for a combination of high-quality protein sources, such as lean meats, dairy, legumes, and plant-based proteins, to optimize recovery. Incorporating adequate protein intake after workouts is crucial for individuals seeking to enhance strength and overall fitness.
