Varying workout intensity levels, such as engaging in both aerobic and anaerobic exercises, offers numerous physical benefits. Alternating between high-intensity and low-intensity workouts can improve cardiovascular fitness, enhance stamina, and maximize calorie burn. This practice may also reduce the risk of overtraining and injury by allowing different muscle groups to recover while still benefiting from physical activity. Additionally, varying intensity keeps workouts interesting and motivates individuals to stick to their fitness goals, leading to sustainable long-term adherence.
