text: what is the average heartbeat per minute for a 44 year old, man?   it depends on how active you are. it shouldn't be over 100 resting(thats if your in bad shape). if your in really good shape, it could be as low as 50. any where in between is average especially from 60-75. lance armstrong's resting heartbeat at the peak of his career was 46 beats per minute resting. that shows he is in amazing shape.
