The correct answer is target heart rate is the term that refers to the number of beats per minute that you aim to achieve during a workout.
Your target heart rate is a number range that represents how fast your heart should beat when you exercise. "A higher heart rate is a good thing that leads to greater fitness," says a cardiologist at Johns Hopkins.
Subtraction of your age from 220 yields your maximum heart rate. If you're 45, for example, subtract 45 from 220 to get a maximum heart rate of 175. This is the maximum number of beats per minute your heart should have during exercise."Aim to be at your THR for 30 minutes most days of the week for daily exercise," she says. "The ACSM and CDC recommend that healthy adults spend 150 minutes per week in their THR zone."
