One squat forward, 2 crunches back

Well I'm making great profess in my 200 squat challenge. On my last exhaustive test I did 100 squats, so I have moved onto the final week. Week 6- and I just completed day 1. Meanwhile, I struggled with week 3 of the sit up challenge, so I am repeating it and maybe I can give it all the attention it deserves when I finish the squat challenge.
