Resting Heart Rate

Heart rate (HR) is the number of times that the heart contracts, usually expressed in a 1-minute time frame.

In order to measure resting heart rate, lightly press index and middle finger against the radial artery in the groove on the lateral wrist.

beats per minute

The American College of Sports Medicine recommends an exercise intensity of 40/50% – 85% HRR in order to satisfy the expended caloric need.

The intensity and the duration of the exercise are inversely related and jointly determine the total caloric expenditure of the exercise session.
