To find your maximum heart rate as a 12 year old, you would use the formula 220 - age.
So, 220 - 12 = 208 beats per minute (bpm) would be your maximum heart rate.
To find your target heart rate zone, you would then calculate 70% and 85% of your maximum heart rate:
70% of 208 bpm = 0.7 x 208 = 145.6 bpm
85% of 208 bpm = 0.85 x 208 = 176.8 bpm
Therefore, your target heart rate zone as a 12 year old would be between 146 bpm and 177 bpm.
If you are 12 years 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 zone?
What would be your upper limit?
