Recovery days are essential in a workout routine as they allow the body to repair and rebuild muscle tissue. These rest periods are crucial for preventing overtraining, reducing the risk of injury, and improving overall performance. Effective recoveries help restore energy levels and restore glycogen stores, leading to better workout quality in subsequent sessions. Moreover, recovery promotes psychological well-being, as it helps athletes maintain motivation and reduce burnout. Balancing workout days with recovery is vital for achieving long-term fitness goals.
