That's fine: Reference ranges for creatine kinase are for people who don't exercise. Athletes commonly have values in the thousands. Good for you.

I work out 3-5 days a week for last two years, had to take a break last pregnancy. noticed my resting heart rate is decreasing. Right now as I type this its 55 bpm. I feel normal. Is lower heart rate because I'm more athletic and my heart is stronger?
