Here is a quick update on my couch to 5k experience. As of now I am staying away from all forms of exercise until I get and understanding of my cardio system. I say this because a continuously elevated blood pressure and lightheadedness landed me in the ER. When you are 60 you can’t fool around by trying to dodge symptoms. I am hoping that some test will reveal the source of the problem and that it is treatable. Until then…?
