Once you can feel your pulse, count how many beats you feel in 15 seconds. Multiply this number by 4 to get your heart rate. For instance, 20 beats in 15 seconds equals a heart rate of 80 beats per minute (bpm).
You would measure the beats per minute. Before exercising, take your heart rate and record it. After, look at your heart rate and record it (should be higher). To do this use a heart rate monitor.
