Recovery days in a workout schedule are essential for muscle repair, injury prevention, and overall performance improvement. During recovery, the body replenishes energy stores and reduces muscle soreness, enabling better adaptation to training. Without adequate recovery, overtraining can occur, leading to mental burnout and physical fatigue. Incorporating recovery days helps maintain a sustainable workout routine and enhances long-term fitness gains. It is crucial to listen to the body and recognize when recovery is needed, ensuring optimal progress and minimizing the risk of setbacks.
