Answer:
Target heart rate is the range of heartbeats per minute that a person should aim for during exercise in order to achieve the desired cardiovascular benefit. The target heart rate range is typically calculated as a percentage of a person's maximum heart rate, which is estimated based on age and gender. The American Heart Association recommends a target heart rate range of 50-85% of a person's maximum heart rate during exercise, depending on the individual's fitness level and exercise goals. Maintaining a target heart rate within this range can help improve cardiovascular health, increase endurance, and burn calories efficiently.
