Final answer:
To find your target heart rate, calculate 60% and 85% of the number obtained by subtracting your age from 220. The factor affecting this percentage is how hard you want to work during exercise, not your resting heart rate, BMI, or workout duration.
Step-by-step explanation:
The factor that determines the percentage to use to find your target heart rate is how hard you want to work. The process to calculate your target heart-rate zone involves several steps that incorporate your age and desired intensity level:
- Subtract your age from 220 to find your maximum heart rate.
- Multiply this number by 60% to find the low end of your target zone.
- Multiply the number from Step 1 by 85% to find the high end of your target zone.
Your resting heart rate, body mass index (BMI) category, or the length of time you intend to exercise do not directly affect the percentage used to calculate your target heart rate.
By understanding the relationship between exercise and heart rate, you can better manage your workout intensity. It's important to note that heart rates can vary based on age and fitness levels, which is why establishing a target zone personalized to your individual circumstances is crucial for effective training.
