Your RHR is the number of times your heart beats per minute while you're at rest. Think of it as the heart’s “idling speed”—the lower it is (within healthy ranges), the more efficiently your heart is working. It’s a great indicator of your cardiovascular fitness and can even give clues about your overall health.

Heart rate variability (HRV) measures the variance between each heartbeat controlled by the autonomous nervous system (ANS). This system operates behind the scenes, regulating vital body functions such as heart rate, blood pressure, breathing, and digestion. The ANS is comprised of two systems: the sympathetic nervous system, responsible for fight or flight responses, and the parasympathetic nervous system, responsible for relaxation and recovery.
