Got 3 miles in on the bike. Brought up more coughing that my walk yesterday. Probably because I was pushing myself harder. It felt good to push myself yesterday so I did it again today. :-)
The coughing is likely a good thing. Work the rest of that gunk out of my lungs.
I wish I had known when I was younger how good it feels to exercise. I didn't know I loved it until it was hard. I didn't know I wanted to run until I couldn't. It's never too late to figure these things out though. :-)
