wow everyone with such low resting heart rates. I have never checked mine when I first wake up maybe I will and see if there is a difference.
69 BPM right now
Probably, I did mine three mornings in a row, it's said to be more accurate, mine was the same each day, then one night in class we had to take it before doing some cardio, after a rather large coffee and eca stack it was 72!
I can see now why eca works so well!!!
