I haven't counted in a while and was surprised to find today was day 2570 in my continual every day 5 mile walk. For the past 2.5 months, I have been running (slow jogging) at least 3 of the five miles and sometimes the whole thing. My resting heart rate most mornings when I awake is now around 55. I am able to get my heart rate up to about 150 when I push the jogging. I am hopeful it is helping me to be more fit. It feels like it. I also still am at a normal BMI too.
