"Burn it Up" was supposed to start tonight...but it simply will not. I really had good intentions of continuing on while on vacation, but I was simply too busy there, and I felt ok when I got back, but the following three days I was still experiencing some jet lag, so between spending some good time with the kids and sleeping, neither of us had time to do much! So, this slipped. I will start Week 5 with a few days of "Ramp it Up" and see how it goes. If all progresses without any next-day soreness, I'll jump into "Burn it Up" mid-week. If not, I'll re-evaluate to see if I need to extend the program for my lapsed week.
