How to Engage Your Core While Sitting

Think you have to hit the mat or gym to work your core? Think again. Whether you’re reading a book, riding in a car, or catching up on emails, you can sneak in a surprisingly effective ab workout while sitting.

That’s good news, because a strong core is essential for healthy aging. Your core muscles help you stay balanced, maintain good posture, reduce back pain, and make everyday movements like getting up from a chair or reaching overhead feel easier.

So if you’re intrigued, you’re not alone. Let’s explore how to engage your core while seated, along with a few beginner-friendly exercises to help build strength gradually and effectively.

What Does It Mean to “Engage Your Core”?

Your core includes more than just your abs. It’s a group of muscles in your abdomen, back, sides, and pelvis that work together to support your spine and keep you stable.

To “engage your core” means to gently activate these muscles, similar to tightening a belt around your middle, without holding your breath or tensing your whole body.

Here’s how to find that feeling:

• First, sit tall near the edge of your chair, feet flat on the floor.

• Then, imagine someone is about to poke you in the belly – naturally, you’ll brace your midsection just a bit. That’s core engagement!

• You should still be able to breathe and talk comfortably.

Once you know what it feels like, you can practice holding this engagement for short bursts throughout the day.

Tips to Engage Your Core While Sitting

1. Check Your Posture

   Sit with your shoulders over your hips, feet flat, and back tall. Avoid slouching or leaning on the backrest if you’re able. By doing so, you allow your core to engage and do more of the work.

   
   

2. Think “Up and In”

   Gently draw your belly button in toward your spine and imagine lifting your ribs away from your hips. Hold for 5 to 10 seconds, then relax. Repeat a few times an hour.

   
   

3. Add Movement

   Try seated marches, torso twists, or lifting one foot at a time. Any movement that challenges your stability helps strengthen your core, especially if you keep those muscles gently engaged.

   
   

4. Use a Small Prop

   Sit on a stability cushion or folded towel to create a less stable surface. Your core muscles will naturally activate to help you stay balanced.
