Protein is essential for muscle recovery after exercise as it aids in repairing and rebuilding muscle tissue that is broken down during physical activity. Consuming protein post-workout facilitates muscle protein synthesis, a process vital for recovery and adaptation to training stress. This helps not only in reducing muscle soreness and damage but also in promoting gains in strength and muscle hypertrophy. Optimal protein intake varies depending on individual fitness goals, but its significance in recovery cannot be overstated in any exercise regimen.
