Improving endurance can be achieved through several effective methods. These include incorporating interval training, which alternates between high-intensity and moderate-intensity exercises to enhance cardiovascular efficiency. Gradually increasing long-distance running or cycling workouts helps build stamina over time. Additionally, strength training can enhance muscle endurance by improving oxygen utilization. Proper nutrition, particularly a well-balanced intake of carbohydrates for energy, is also crucial for sustaining prolonged activity. Finally, consistent practice and targeted recovery protocols, such as adequate sleep, play significant roles in improving endurance over time.
