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 your maximum heart rate, what would be your lower range or your target heart zone?

What would be your upper limit?

To find your maximum heart rate at 12 years old, you can use the formula:
Maximum Heart Rate (bpm) = 220 - Age

For a 12-year-old, the maximum heart rate would be:
Maximum Heart Rate = 220 - 12 = 208 bpm

To find the lower range or target heart rate zone, you need to calculate 70% and 85% of the maximum heart rate:

Lower Range = 70% of Maximum Heart Rate
Lower Range = 0.7 * 208 bpm = 145.6 bpm (approximately 146 bpm)

Upper Limit = 85% of Maximum Heart Rate
Upper Limit = 0.85 * 208 bpm = 176.8 bpm (approximately 177 bpm)

Therefore, the lower range or target heart rate zone for a 12-year-old would be around 146 bpm, and the upper limit would be around 177 bpm.
