Started the running program tonight.
Did not die.
Actually, it felt pretty good. The alternating run/walk routine was easy to follow without completely wiping me out, and a quick blood pressure check afterward showed a small spike in my systolic digits but the diastolic was fine. I’ve got a slight tightness in my shins, otherwise no pain. Even the late hour, which I worried about at first, proved quiet and relaxing.
My dog, however, thought I was nuts. He may not get invited Wednesday night.
