Interval training can benefit cardiovascular health by enhancing both aerobic and anaerobic fitness. This training involves alternating periods of intense effort with recovery intervals, pushing the heart to work harder and adapt. By varying intensity levels, interval training improves heart rate response, builds endurance, and increases overall caloric expenditure. Additionally, it can lead to improved insulin sensitivity and lower blood pressure. Incorporating intervals into exercise routines can yield efficient and effective workouts that promote long-term cardiovascular health benefits.
