This is one of those times when I feel guilty for blogging rather than attending to more – dare I say it – important matters.

Like tracking down all my 2010 tax documents for Hubby’s big pow-wow with the accountant tomorrow morning, and blasting through the Ab Ripper X workout I didn’t manage to get to yesterday. (Though I did do Shoulders & Arms, so I wasn’t a complete loser slacker…)

Last night, as I was getting ready for beddy-bye, Hubby spied my bare belly for a nano-second. “Wow,” he said. “Your stomach is looking good.” And upon closer inspection, and some serious squinting, we both think we spotted two vertical grooves flanking my belly button.

Was it a mirage? One too many glasses of Merlot?

No, it was the result of SEVERAL tortuous sessions of Ab Ripper X, which I’ve complained bitterly about over the last eight weeks or so. It’s really short, under 20 minutes, which when compared to other P90X workouts like the 92-minute Yoga X, seems like warp-speed. But it’s brutal. And apparently effective, even when you eat like an idiot, as I have been lately.

In addition to Ab Ripper X, there’s another DVD in the lineup that I will most definitely be working into my post-P90X life. It’s called Core Synergistics, and it’s very, very intense.

A hyper mix of Prison Cell Push-Ups, Banana Supermans and Plank to Chaturanga Runs, Core Synergistics is designed to, as Tony Horton puts it, “tighten the entire mid-section into a hard, ripped sheet.”

Doesn’t that sound fantastic? I’ve never had a hard, ripped sheet in my life. But I think I’ll be one happy camper at the town pool this summer if I pull that off.
