Unformatted text preview: - beats per minute When taking your heart rate during an exercise session, count your pulse for only 6 seconds and multiple by 10 (add a zero). The heart rate drops rapidly when activity stops, therefore, to receive an accurate exercise pulse, a 6-second count is most reliable. Example: number of beats in 6 seconds = 15 multiply by 10 by adding zero = 150 bpm This example indicates that the intensity level of exercise for this 20-year-old is sufficient for improving the function of the heart, lungs and blood vessels. If the exercise pulse is below 130, the intensity level can be increased; if the pulse is over 180, the intensity of the workout can be slowed down (more benefits are not derived by working over 90% of MHR - fatigue will just set in faster)....
