How many times does a heartbeat in a minute while resting?

the always beats resting or not, if it stopped you would die.

But assuming you mean how often does it beat during rest. Well that depends on how fit you are.

Someone, like a runner, who does a lot of Cardio-vascular exorcise (gets the heart pumping fast) will have stronger heart muscles than some one who sits around all day. This means that their heart doesn't need to beat as fast as it can push more blood around the body in one pump than the other persons.

for the average healthy (but not fit) man its 64-72 beats per minute at rest and for the Average healthy Woman around 72-80 BPM
