What is the formula for calculating target heart rate during aerobic exercise?

The formula for calculating target heart rate during aerobic exercise considers both the maximum heart rate and the resting heart rate, integrating an intensity factor that reflects the desired level of exertion. This method ensures that individuals exercise within their optimal heart rate zones, promoting cardiovascular benefits and efficiency.

The correct formula involves determining the difference between the maximum heart rate and the resting heart rate, known as the heart rate reserve. By multiplying this difference by a specific intensity level (which can range from moderate to vigorous), and then adding the resting heart rate back into the equation, individuals establish their target heart rate. This calculation allows for a personalized approach to aerobic exercise, accommodating variations in individual fitness levels and specific goals.

The other choices do not accurately account for both maximum and resting heart rates nor do they employ a factor for workout intensity, making them less effective for establishing a practical target heart rate for exercise.
