Okay, after doing a search on HRMs I have learned that the most important thing is overall calorie burn. My question is, now that I have used my HRM for over 3 weeks, I noticed it takes longer for me to get my heart rate to elevate. Does this mean that my body is becoming more fit? Am I doing something wrong? Also, how long (on average) should it take me to "get back to normal?"
Any additional words of wisdom are welcomed and appreciated.
Thanks!
