Improving aerobic capacity can be achieved through various methods, including consistent cardiovascular training. Engaging in activities such as running, cycling, or swimming for extended periods increases endurance. Additionally, incorporating high-intensity interval training (HIIT) can significantly boost aerobic fitness by alternating short bursts of intense activity with rest or low-intensity periods. Gradually increasing workout duration and intensity, along with proper recovery, allows for aerobic conditioning without overtraining. Monitoring heart rate can also help optimize training intensity and improve overall cardiovascular performance, leading to enhanced aerobic capacity over time.
