Base training

Base training focuses on building aerobic endurance through low-intensity, high-volume workouts. It enhances the body's ability to efficiently use oxygen and burn fat for fuel. This phase typically includes long, steady runs and cross-training activities. For example, marathon runners might spend months in base training to build a strong aerobic foundation before adding speed work. It matters because a solid aerobic base reduces injury risk, improves recovery, and supports higher-intensity training phases. Consistent base training leads to better overall performance and endurance in races.
