This is a live post as I am doing them.

Week 4, Column 1, Day 2:

14 - Ok that's tough but not so bad anymore.
16 - Had to rest (on top of my arms) at 12 but kept going.
12 - Sort of got mixed up with the breathing but took a second to get going on the right track again. It's hard, but it's sort of nice that now it's 12, not 6, that's feeling hard.
12 - Not too pretty either, but did it. Now am I really supposed to do 18? I'll take a longer rest before I try that.

Wow. I did 18. My arms are quite shaky and I managed to hike up my heart rate quite a bit. Stopped at 10, and then 13, and then 2 more, and then 2 more, and then one last.

So that's 72 for today. I'm getting scary-close to 20 in one set (but nowhere near 100!!!!!!)
