How many push-ups can I do?

2012:
No idea. Maybe five? I don't do exercise.

2013:
probably none. But I do plan to run half marathon next month and beat my time from last year.

2018:
Recently, I have been able to do 15 unbroken Rx push-ups, not just knee on the floor, push-ups. Before it used to be 10. Working on getting that number much higher.
