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? Response area What would be your upper limit?
To calculate your maximum heart rate as a 12-year-old, you can use the formula: 220 - your age. So, 220 - 12 = 208 beats per minute (bpm).
To find your target heart rate zone, you would calculate 70% and 85% of your maximum heart rate.
70% of 208 bpm = 0.70 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 (lower range) and 177 bpm (upper limit).
