I got codex to count my total heartbeats from my Garmin data. For four random days the counts were 72.252, 73.823, 68.922, 70.991.

According to google: "typical range for total heartbeats is 86,400 to 115,200 beats per day"

I run every day which would add a lot of beats, but my resting HR is 36 (pushed down by exercise i presume) with a daily average of 50 BPM. So in total a trained person may spend less of their heart beats.
