To effectively build endurance over time, incorporate a variety of strategies such as progressively increasing aerobic activity duration and intensity. Implementing interval training, cross-training, and rest days into the routine promotes overall fitness without overtraining. Consistency is key, so gradually extending the distance and pace of workouts is crucial. Nutrition should also be considered, as a well-balanced diet rich in carbohydrates and hydration supports sustained energy levels, allowing individuals to perform at their best.
