I apologize if this has already been discussed, but I was thinking more about HIIT (high intensity interval training).
Basically, I follow this method, but I walk 5 min, run 7 min, walk 3, run 7 min, walk 2, run 4, walk 2 = 30 min of cardio. Is this still considered not enough cardio to be in the girl zone?
Here is an article I found:
