Target heart rate: (220- age* 50 to 85) if my age is 15 what would my target heart rate be?
To calculate your target heart rate using the formula (220 - age * 0.5 to 0.85), where your age is 15:
Lower limit: (220 - 15) * 0.5 = 102.5 beats per minute
Upper limit: (220 - 15) * 0.85 = 178.5 beats per minute
Therefore, your target heart rate range would be between 102.5 and 178.5 beats per minute.
