"And what if you are walking 17 mph but it is all hills (up and down)"
That's some pretty fast walking!!!
My doctor told me to forget the calculations and heart monitor devices and let your body tell you (as long as you are pushing yourself).
and basically, you know when you are pushing yourself when " you can answer a question, but not comfortably carry on a conversation."
the most important thing here is I got my doctor's advice.
