What does THR stand for? How is it calculated?
What will be an ideal response?
Answer: Target Heart Rate is calculated to be between 55 and 90% of your maximum heart rate. (Your maximum heart rate is 220 minus your age.) The percentage depends on your health and fitness level: a higher percentage is appropriate for very fit people and a lower percentage is appropriate for beginning exercisers.
