Final answer:
The resting heart rate is not necessary for calculating the target heart rate range, which is typically determined by subtracting age from 220, selecting an intensity level, and calculating heart rate reserve. The correct option is A.
Step-by-step explanation:
The step not necessary to calculate your target heart rate range is (A) Find your resting heart rate. While knowing your resting heart rate can be helpful for overall heart health monitoring, it isn't a required statistic for calculating the target heart rate for exercise. The standard method to find your target heart-rate zone includes:
- Subtract your age from 220 to find your maximum heart rate.
- Choose your desired intensity level (usually between 60% to 85% of the maximum heart rate).
- Calculate your heart rate reserve by subtracting the resting heart rate from the maximum heart rate, and then multiply it by the intensity level plus your resting heart rate again to get the range. The correct option is A.
