A recommended rest period between strength training sessions typically ranges from 48 to 72 hours, allowing adequate recovery and muscle repair. This time frame is essential to optimize muscle growth and avoid overtraining. Individual factors, such as training intensity, fitness level, and age, can influence recovery needs; thus, listening to the body is critical. Adequate rest ensures that muscles can rebuild stronger, enhancing performance in subsequent sessions, and reducing the risk of injury while promoting long-term fitness goals.
