Can't have great workouts every day, the important part is that you did it. I've found that Day 2 is less challenging the more I stay at a certain level so I added a five pound weight to my pull-ups last week. Another option is to go slow on each rep for day two. I'll probably be doing something like this next week and the next as I graduated L4D3 with a time of 4:59 and L5D3 adds 6 pull-ups, 10 push-ups, and 10 squats! I'm not thinking I'll be able to come in sub-5 minutes this week.
