Rest days in a workout schedule offer potential benefits, including muscle recovery and prevention of overtraining. Allowing time for rest enables muscles to heal, grow, and replenish energy stores, leading to improved performance in subsequent workouts. Incorporating rest days helps reduce the risk of injury, fatigue, and burnout, promoting a more sustainable and enjoyable fitness routine. Furthermore, scheduled rest can improve mental well-being, as it provides a break from the intensity of training and fosters adherence to long-term fitness goals.
