I've decided that next week I'm going to repeat week 1. I was a little disappointed that on the last set of the week I only managed to do 4 when I was supposed to do 5 reps. The program does suggest though that if you encounter any difficulty or struggle that you should either repeat the initial test or repeat the first week. I don't see it as starting over from scratch though. I do feel strengthened by my first week and suspect it will be easier next time. It was a minor setback but progress nonetheless.
4,5,4,4,4 (last set was supposed to consist of 5 reps but fell short) resting 2 minutes between sets
