however, in reality, it goes more like...
Day 1: This is so easy! I'm going to do two sets of these in addition to my other workout.
Day 5: Wow I feel like I'm cheating! Nothin' to it!
Day 10: OK, I think I won't do two sets any more, but I'm still going to keep up my regular workout.
Day 15: Oh crap, I didn't have time to do the workout yesterday or the day before, thank god there are "rest days" in which to make them up...
Day 21: Holy hell, I didn't do another two days in a row. Looks like I'm doubling up today. Oh hell no I won't be doing my regular workout.
Day 25: Geebuz, I've accomplished nothing today but this ab challenge - no cardio, no other workout, and there's no way I would even consider doing this twice.
Day 26: LOOK AT MY ABS I AM SO RIPPED. ....what am I going to do at the end of the month? Am I going to have to keep up this workout forever?
I'll admit I cheat a bit on the sit-ups - I do them on a stability ball because my tailbone can't handle real ones (no seriously I've done major damage that way).
With having to catch up from the weekend, I am proud to tell you that in the last three days I have done:
175 leg raises
7 minutes (and some change) worth of plank
