In brief: Bradycardia

There are many reasons to have a resting bradycardia (low heart rate).
Commonly, in people who are fit, the cardiovascular adaptations associated with fitness increase the efficiency of the cardiovascular system which allows a lower resting heart rate. There are diseases that can lower heart rate, including brain problems, GI problems, endocrine problems, and heart problems.
