Today, my resting heart rate was determined to be 52 bpm. Actually, the first number they came up with was 48, and they found that shockingly low so they checked again.
I find this particularly interesting because my super-fit friend said something similar about a week ago. Her rating rate is 58. My husband's is 80.
September 1st will be one year since I ran my first 5k. Since then, I've run 2 more plus a 7k, a 50 mile bike tour and a 20 mile bike tour. I also weigh more than I did a year ago and it's not muscle. So I'm taking my victories where I can find them, in resting heart rates and personal bests.
