Re: Resting Heart Rate 42 BPM; Good, Bad?
Im not sure about that Alex. I am 33, my hr in the morning is 50 and my max is somewhere in the 185-190 area.
And I most likely cant run 5k in one piece, my conditioning is simply terrible.
Ive read/heard that fitness can be "measured" how long it takes for your HR to return to normal after being at max.
