To find your maximum heart rate at age 13, you can use the formula: 220 - age. Therefore, your maximum heart rate would be 207 beats per minute.
To calculate your target heart rate zone, you would take 70-85% of your maximum heart rate.
The lower range of your target heart zone would be 145 beats per minute (70% of 207).
The upper limit of your target heart zone would be 176 beats per minute (85% of 207).
