Recovery days are vital within a training plan as they allow the body to heal and adapt to the stress of exercise. Rest is crucial for muscle repair, replenishment of energy stores, and prevention of injuries. Without proper recovery, individuals risk overtraining, which can lead to decreased performance and increased fatigue. Incorporating scheduled rest days helps maintain motivation and long-term adherence to a fitness routine. Enticing activities such as light stretching, yoga, or leisurely walks can aid recovery while promoting mental and physical refreshment.
