I actually did this one last night but I made it through the workout in Column 2: 9, 8, 6, 5, and a max of 10, for a total of 38 pushups.
I'm being generous with my rest periods in between the levels. The sheet calls for 90 seconds (or more if necessary) and I always seem to feel that more is necessary. 🙂
There's probably a trade-off between conditioning myself to power through the sets with only the minimum time in between levels or trying to take it a little “easier” and do more pushups at this stage of the game. What little I do know (or think I know) is that the strength building comes from the last part of the set at which point the muscles tear under the exertion and are repaired, stronger, over the rest period. Maybe taking the levels a little bit slower makes the workout more aerobic and less strength training?
I don't know. But I do know that doing the pushups either way is better than not doing the pushups. Like Jim said, yesterday I did 38 more pushups than I probably would have done without the program.
