I rested for two days in between Week 1 and Week 2, and did 41 pushups for tonight's workout. I'm in column 2 at the moment: 9, 8, 6, 4, max = 14.
I've heard anecdotal evidence that even as early as the first day after starting a new exercise it's possible to outperform the first try. For example, a friend of mine recalled the time he started working on the bench press. The first day he did 110 pounds, and the following day he could do 120 pounds.
It's pretty cool that even after just a week I can do nearly twice as many pushups (fourteen) in a row — after four sets of pushups — than I could on the first day (eight). Maybe that's the way God designs exercise: some quick improvement at the beginning so that we give thanks and stay encouraged, then a lot of hard work after so that we stay humble. 😉
