Recovery days are crucial in an exercise routine as they allow the body to repair and strengthen muscle tissues that have been stressed during workouts. Inadequate recovery can lead to overtraining, increasing injury risk and hindering performance improvements. Incorporating rest days also helps in balancing the body’s energy levels and ensures mental focus for subsequent workouts. Active recovery, such as light stretching or walking, can enhance circulation and facilitate recovery while still keeping movement. Thus, respecting recovery is essential for sustainable fitness progress.
