The purpose of recovery time in a strength training program is to allow for muscle repair and growth. Recovery helps to prevent overtraining, which can lead to fatigue, injury, and decreased performance. Adequate rest between workouts enables the body to replenish energy stores and restore muscle function. Typically, 48 hours of recovery is recommended for the same muscle group. Incorporating active recovery, such as low-intensity activities, can further aid in enhancing flexibility and blood circulation while minimizing muscle soreness.
