If you are 12 years old, which math problem would give you your maximum heart rate? Response area
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?

Given that you are 12 years old, your maximum heart rate would be calculated as 220 - 12, which equals 208 beats per minute.
Your lower target heart rate zone would be 70% of your maximum heart rate, which is 0.7 * 208 = 146. The upper limit of your target heart rate zone, which is 85% of your maximum heart rate, would be 0.85 * 208 = 177.
