Per this page:
More than 20 push ups? I would suggest starting the program on Week 3. Choose either Column 2 or 3 based on the number of push ups you managed in your initial test.
So, I'm starting on Week 3, which is fine because it gives me a 2-week buffer if I don't finish a week like I should. I'll be using the free Logger tool to keep up, as well as trying to post my progress here.
