How do you calculate the target heart rate for exercise?

To calculate the target heart rate for exercise effectively, it is essential to consider a percentage of the maximum heart rate that aligns with the desired intensity of aerobic workouts. The correct method involves taking 70-85% of the maximum heart rate, which corresponds to moderate to vigorous intensity exercise.

This range is particularly relevant for individuals who are looking to improve cardiovascular fitness and endurance. The maximum heart rate is typically estimated by subtracting one's age from 220. Once the maximum heart rate is determined, calculating 70-85% provides the target zones suitable for achieving fitness goals during aerobic activities.

For instance, if someone is 30 years old, their estimated maximum heart rate would be 190 beats per minute (220 - 30 = 190). To find the target heart rate range, you would calculate 70% (which would be 133 bpm) and 85% (which would be 162 bpm) of that maximum. Exercising within this range is scientifically supported as effective for improving overall fitness levels, weight management, and heart health.

Other provided options suggest lower or higher percentages, or a fixed target level that neglects the individual differences based on age and fitness level, which are less effective for personalized exercise planning.
