What Pregnancy Does to Your Core (And How to Rebuild It)

When you are pregnant, everyone always asks the new mom-to be “how they are feeling”, but that care can sometimes feel like an abrupt departure when our new bundle of joy enters the world, leaving a lot of women wondering….what did pregnancy do to my core and how can I restrengthen it?

WHAT HAPPENS TO YOUR BODY DURING PREGNANCY

When you get pregnant, the hormone relaxin involved in growth, metabolism, and tissue remodeling after an injury to our bones, ligaments, muscles or tendons begin to move through the body during the first trimester. This helps prepare the body for childbirth by creating relaxed joints and flexibility around the ligaments and muscles in the pelvic area.

But what no one says is that “looseness” doesn’t just stay in your pelvis. It shows up everywhere.

So if you’ve been feeling (especially approaching Trimester 2):

• less stable in workouts

• like your balance is off

• random aches in your hips or lower back

• or like movements you used to feel in your core are now dumping into other areas

It’s time to adjust your training, especially how we work your core (and yes you absolutely still can and should train your core when pregnant).

THE LINEA ALBA (aka why your core suddenly feels..different)

As your baby begins to grow, your body has to make space—and that means your abs physically separate.

The abdomen is held together by fascia called the linea alba and must stretch to create that room. Think of this linea alba like a piece of Laffy Taffy that holds your six pack muscles together.

Once that “Laffy Taffy” stretches, your core loses its ability to create tension the way it used to.

So if you’ve been feeling:

• like your core just isn’t “turning on”

• a weird lack of strength or control through your midsection

• coning or doming when you sit up, plank, or get out of bed

• your lower back or hips taking over in workouts

That’s your core adapting to the stretch of your linea alba.

For some women, it tightens back up after pregnancy.
But the more it’s stretched (especially with multiple pregnancies), the harder it is for it to naturally regain that same tension.

Which means if you go back to doing workouts the same way you did before, you’re often training around the issue (or actually creating more of a gap) instead of fixing the root issue.

YOUR CORE ISN’T GONE, HERE’S HOW TO REBUILD IT!

The good news is, your core isn’t “gone”. It’s just not functioning the way it used to...yet.

You have over 30 core muscles responsible for your stability, strength, balance, and control. But after pregnancy, you can’t train them the same way and expect them to respond at first.

If your core isn’t creating tension, your body will find it somewhere else, usually your hips or lower back.

That’s why jumping back into crunches and high-impact workouts can actually make things feel worse instead of better.

Instead, rebuilding your core after pregnancy is key!

In Pilates-Inspired Strength Training at Core (LP) Berkley & Rochester Hills, we focus on the deepest layers of your core first, your transverse abdominals and obliques, so you can regain true stability while layering on intensity safely.

Because when your core is strong, so is everything else, and the strength, balance, even how your body looks, starts to fall back into place.

Whether you’re 3 months postpartum or 3 years removed from pregnancy, if your core feels off, weaker, or disconnected…your body is still capable of rebuilding that strength.

You’re not “too far gone,” and you didn’t miss your window. You just need the right approach.

If you’re pregnant or postpartum and your core feels off, weaker, or disconnected, this is exactly what we help you rebuild.
