How do you feel?: The reference range for creatine kinase assumes that the person does not exercise. In my experience, especially with healthy med students, almost everyone who's even mildly fitness-focused has high ck. I've seen labs over 3000 from an afternoon's hard workout. If you have no evidence of muscular dystrophy or myopathy, and you exercise, be proud of yourself.
