Does regular exercise lower resting heart rate. It may reduce it somewhat over time. Aerobic activities such as jogging and cycling enlarge and strengthen the heart so it pumps more blood with each contraction.
Not every exerciser experiences this reduction in heart rate however and it may take years of exercise for it to occur. But low resting heart rate is often associated with high.
