WHEEE!
Back in the day, pre-ROM, I could do maybe three or four of these before my abs felt like they were going to rip out of my torso. It’s basically like doing crunches with a little person attached to you. But now, six months in, guess how many I can do comfortably?
21.
And she’s only getting heavier, folks. : ) 
I hope the ROM people see this recent blog entry of yours, Mike. This makes the best case for ROMMING of anything else you could say, I think. 🙂
