Heart and Breathing Rates. Your heart rate, or pulse, is the number of times your heart beats in a minute. Depending on your age and level of physical fitness, a normal resting pulse ranges from 60 to 80 beats per minute. Your breathing rate is measured in a similar manner, with an average resting rate of 12 to 20 breaths per minute. Both your pulse and breathing rate increase with exercise, maintaining a ratio of approximately 1 breath for every 4 heartbeats.
