What core stability actually means (and why it matters for pain and performance)

When most people think about core strength, they picture six pack abs. However, your core is much more than that.

Understanding what your core is, and how it works can help reduce pain, improve performance, and make your workouts more effective.

What is the core, really?

Your core is not just one muscle. It is many muscles that surrounds your spine and abdomen to create stability and control.

This includes:

• Rectus abdominis (the “six pack”)

• Transverse abdominis (your deep abdominal layer)

• Internal and external obliques (side muscles)

• Diaphragm

• Pelvic floor

• Low back muscles such as multifidi and other small spinal stabilizers

• Glutes

Think of your core as a 360 degree support system that includes both the front and back of your body.

If you are dealing with low back pain, poor posture, or recurring injuries, this system is often a key piece of the puzzle.

The core "hoop" or "cannister" mechanism, and why it matters:

A helpful way to understand the core is to picture a soda can.

• The diaphragm is the top

• The pelvic floor is the bottom

• The abdominals wrap around the front and sides

• The low back muscles and glutes support from behind

When everything works together, this system creates pressure inside your abdomen. This pressure helps stabilize your spine and protect it during movement, especially when lifting, running, or changing direction.

If this system is not working well, your body will often compensate, which can lead to pain or decreased performance.

How to engage your core the right way

A common mistake is thinking core stability means tightening your abs as hard as possible.

That is not what we want.

Instead, we want to create pressure through your core in a way that supports movement.

Try this:

• Sit upright in a chair

• Place your fingertips so they overlap from the front of your hip bones (iliac crest) onto your stomach muscles

• Take a deep breath in

As you breathe in, you should feel your stomach gently expand outward and your muscles press into your fingers. That pressure pushing into your hands is what helps stabilize your spine.

You are not sucking in your stomach or bracing as hard as possible. You are creating a controlled, supportive pressure your body can use during movement.

Core training for rehab vs performance

Core exercises should match your current level, but not too easy. If you are recovering from pain or injury, start with control and coordination.

Common ones that we start with are:

• Dead bugs

• Bird dogs

• Anti rotation exercises

• Bridges

Training your core for real life movement:

As you improve, you'll want to incorporate exercises that move the core in a controlled manner through different ranges and planes of motion. This builds a strong foundation to support you in real life (where we do need to bend, twist, and flex our spine in daily movements!).

Your core needs to:

• Resist movement when needed

• Allow movement when appropriate

• Control transitions between the two

Eventually, you should train all directions of movement:

• Flexion

• Extension

• Side bending (lateral flexion)

• Rotation

Progressive core exercises that carry over to daily life and sport include:

• Deadlifts (yes, you read that correctly).

• Squats

• Side bends

• Cable rotations

• Med ball slams

• Back extensions

• ...and many many more!

These exercises train your core to stabilize while your body is moving, which is what protects your spine and improves performance.

Bottom line

Core stability is not about having visible abs. It is about how well your body can support and control movement. If you have been stretching, foam rolling, or doing ab workouts without lasting results, you may be missing this piece.

Training your core as a system can help you move better, feel stronger, and stay out of pain.
