A few months ago, I ran six miles. I did it again today, but at 7 MPH instead of 6 MPH.
Next week, I'll increase the speed on the treadmill to 8 MPH and start over again at 2 miles.
I'm also making progress toward my goal of doing 100 push-ups in a single set. So far, I'm up to 64.
At 33, I'm in the best shape of my life.
