Hilarious Pic: Flexing My Abs Makes a Pregnant Triangle!

What a weird world is Pregnancy Land!

I had no idea that my abs would do something ridiculous when interacting with my massively pregnant belly: turn me into a Triangle Woman!

Here is my normal, round 8.5-month pregnant belly...

At the right you see what my 8.5-month pregnant belly looks like at rest. An innocent, moon-like orb, right?

Now scroll down to check out what happens when I flex my abs– an action necessary to struggle out of a couch or bend down…

BOOM: Triangle!!! (Yes, I am wearing brown with black sweatpants. Forgive my questionable pregnant style and focus on the funny triangle…)

Flexing Abs + Preggo Belly = TRIANGLE!

What Does Triangle Belly Feel Like for Baby?

“Watch out!” yells Colin. “You’re gonna squish our little guy with your crazy triangle abs!”

But never fear… our pumpkin boy seems fine. He dances in utero whether I’m flexing or not. In fact, he’s punching my ribs now. Maybe becoming a triangle is a cosy massage for him? They do say babies love being hugged tightly. Maybe he specifically enjoys a triangle-shaped squeeze?

Don't worry-- Our Little Pumpkin Boy isn't too squished!

What Does Pregnancy Triangle Mean?

What puzzles me is why I’ve never, ever heard of anyone else with this odd pregnancy symptom, despite obsessive research. Sure, I’ve written about 20 Funny Pregnancy Symptoms of the Third Trimester, but each of those symptoms is general knowledge among those who use iPhone pregnancy education apps. (You know, apps that liken the size of your fetus to different fruits. Good times.)

But… Triangle Abs? I’ve NEVER heard of anyone else having this goin’ on. Am I alone here? Is it due to my ridiculously strong torso as a result of my years of varsity high jumping and signature “L” back-bends around the world?

Either way, I’m happy that a symptom I have heard of — that your abs RIP IN HALF during pregnancy — appears to not yet be in effect in my body. Or… does this mean they HAVE ripped? Who knows. Anyway, we now have 2 weeks and 2 days until our Estimated Due Date. What final surprises does Pregnancy Land hold???

Regaining Core Strength and Abs After Pregnancy

Feb. 2021 Update: Looking back at this article, I definitely had some damage done to my core muscles during my two pregnancies. I’m thrilled to report, however, that it was all solvable through persistent (doctor-suggested) exercise over a series of years. Want to see the “after” photo?

I totally have triangle abs! And my husband says the same thing! I'm only 17 weeks along but we both get hysterical when I flex! Glad to see someone else has this too!

Thank you so much for writing this post! Iā€™m 23 weeks and when I stretched my back this weird bump popped out! I had to see what was going on. So random....All the crazy things your body goes through that no one tells you about.

Hi Lillie, LOVE your pregnant belly pics and SO GLAD to see that you call your bellybutton your friend!!! I say that because so many moms-to-be ABSOLUTELY HATE it when their bellybuttons come poking out.I on the other hand don't find them unappealing in the least.As a matter of fact,I feel like a pokey bellybutton makes a pregnant belly that much more APPEALING and PLEASING TO LOOK AT!!!!!!!!!!!!!!!!!!!!

Hehe -- glad you love bellybuttons! :)

Same here - with every pregnancy! I tried to attach a pic but it won't work. So freaky right?

I have always had this dramatic triangle with each of my 6 pregnancies. You're right that the abs split during pregnancy, which causes the shape. The thing you have to watch for is making sure the abs go back all the way aftwerards (some women's don't). Try searching for "midline protrusion in diastasis recti pregnancy". If you search google images and scroll down a little, there is a photo that looks very much like yours. My stomach didn't go back to being flat after my pregnancies - I have a lump that won't go away (that's not fat) from the diastasis recti causing a bit of a hernia there. Just fyi. =)

Yes!!!! I got your email. Solidarity, fellow triangle belly gal!

I came across this post when googling "flexing abs while pregnant." I was curious what it would come up with. I am 9months and when I flex my abs it pulls my belly in and up really high and becomes about half the size it normally is at rest. I did however want to share that I don't get the triangle shape when flexing. But I do get a strong triangle shaped belly when I do one certain activity. So as far as triangle shaped pregnancy belly goes, it can be pretty normal. :)
