So after admitting the other day that I don’t overplan my workouts, it occurred to me that now every time I post a Core on the Floor workout, you’re going to think I’m feeling tired.  Ha!

And you know what?  I actually really am.  The marathon training miles are really adding up, my kids’ Cross Country schedule is pulling me hither and yon, and the only thing I thought I had the energy for today was some ab work.  Maybe something where we lay on the ground a lot, hmmm?  Doesn’t that sound nice?

But then – dangit! – when I started noodling it out and deciding what I wanted to do, I really wasn’t content with doing the same ol’ same ol’, so I went looking for some unusual exercises.  And once I had some different exercises, I thought, “Oh, you know what would make this really tough?  Using the interval timer!”  All of a sudden, my easy-peasy workout became this Killer Core.

And I’m so glad it did!  You know how that goes.  You’re tired and think you can’t possibly do a good workout, but then you do one anyway and you feel amazing afterward?  That’s how I felt when I was done with this.  I hope you do, too!

Follow along in real time, or take this breakdown with you (though you might want to at least watch the video, because I totally made up names for some of these exercises!)
