If you are 13years old, which math problem would give you 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 your lower range or your target heart zoneWhat would be the lower range or your target heart zone?

The math problem that would give you your maximum heart rate is:

220 - age = maximum heart rate
220 - 13 = 207 beats per minute

To find the lower range of your target heart rate zone, you would calculate 70% and 85% of your maximum heart rate:

70% of 207 = 0.7 x 207 = 144.9 beats per minute
85% of 207 = 0.85 x 207 = 175.95 beats per minute

Therefore, the lower range of your target heart rate zone would be 145 beats per minute and the upper range would be 176 beats per minute.
