Definitely the most difficult for me so far. My body actually failed me...I had to give in at 260 lunges. I did the other 40 later that night so technically I finished, but not the way I wanted to.
Finally a day with no pain in my shins! 33s today and it was a good one! I am starting to like these circuits better than the typical weight lifting sets. This 30-30 is turning into a teaser for me...I want to try the other programs now!
