Wrong & Right Way to do Oblique Ab Crunches

Kymberly Williams-Evans, MA and Alexandra Williams, MA

We are asked all the time about working the sides, “muffin top,” “love handles,” or waist. So we shall waste no time and show you the wrong and right way to do an oblique crunch.

Enjoy a quick video tutorial from Thing 1 and Thing 2:

And now, a message from your sponsor (the obliques):

Internal & External Obliques

X Marks the External & Internal Obliques


  • Your external obliques run diagonally, forming a V in front. Imagine you’re putting your hands into a vest or front coat pocket – voila!
  • Your internal obliques run at right angles to your external obliques and form an inverted V.  Put your hands on your hips with your thumbs in front and fingers behind, pointing down as if putting your hands into back pockets.

For those of you who like the nitty-gritty, oblique-y details, here’s an excellent definition by our colleague Dr. Len Kravitz, who teaches at the University of New Mexico and is way smart!

Now you know the official terms for “I want my waist to be fit and trim, but don’t want to copy any of those lame exercises I see people do in the gym that are destined to hurt their back or neck.”

Well, did you do the oblique crunch along with us? Feel free to post a video of your wrong or right favorite ab move on our fan page.  Or comment below between reps. 412, 413, 414, 415 ….
