Okay, I just finished the second workout of week 5, and there is no way I could complete all the reps. Starting on the 3rd set, I needed to do assisted pullups on the last few reps. To me, the program just took an unrealistic jump in intensity. Day 3 of this week looks even more impossible.

I'll continue doing the program using assisted reps when necessary. If I can do twenty at the end of week six, then great! If not, oh well. I'll be disappointed, but it's time for me to get back to my normal workouts.
