If you are 13 years old, which math problem would give you your maximum heart rate?
If you are 13 years old, what is your maximum heart rate?
After finding your maximum heart rate, remember your target heart rate zone is 70-85% of you maximum heart rate.
What would be the lower range or your target heart zone?
What would be the upper limit?
To find the maximum heart rate, you would use the formula: 220 - your age. So for a 13-year-old, the maximum heart rate would be 220 - 13 = 207 beats per minute.
To find the lower range of the target heart rate zone, you would take 70% of the maximum heart rate: 0.7 * 207 = 144.9 beats per minute.
To find the upper limit of the target heart rate zone, you would take 85% of the maximum heart rate: 0.85 * 207 = 175.95 beats per minute.
Therefore, the lower range of the target heart rate zone would be approximately 145 beats per minute and the upper limit would be approximately 176 beats per minute.
