“Strengthen your core” is one of the most common pieces of health advice – whether you’re in the gym, visiting a health practitioner, or scrolling through social media. Despite how often it’s said, many people don’t fully understand what it actually means, or more importantly, why it matters.
The truth is, your core is much more than just your abdominal “six pack”. It is a complex system of muscles that plays a fundamental role in supporting your spine, helping prevent injury, and allowing your body to move efficiently. When your core is functioning well, it provides a stable foundation for everything you do – from sitting and standing to lifting, bending, and exercising.
In this blog, we’ll explore what the core really is, why it matters for spinal health, and how you can begin building a stronger, more supportive core.

What Is the Core?
The “core” refers to a group of muscles that surround and support your trunk and spine. Rather than being a single muscle group, it functions as a coordinated system made up of both deep stabilising muscles and more superficial movement muscles.
Key components of the core include:
- Transverse abdominis: A deep muscle that wraps around the torso, helping to stabilise the spine and regulate internal pressure
- Multifidus: Small, deep spinal muscles that provide segmental stability between individual vertebrae
- Pelvic floor: Forms the base of the core, supporting pelvic organs and contributing to pressure management
- Diaphragm: The primary muscle for breathing, forming the top of the core and working in coordination with other core muscles
- Obliques: Internal and external obliques assist with rotation and side bending
- Rectus abdominis: Helps flex the torso, control pelvic tilt, and support the lumbar spine
- Erector spinae: A key extensor muscle group that supports upright posture and controls spinal movement
Together, these muscles work as an integrated unit to support and protect the spine.
Why Does Core Strength Matter for Your Spine?
Your core acts like a natural “corset” for your spine, providing dynamic stability – meaning it supports your spine not just at rest, but during movement.
When core muscles are weak or poorly coordinated, the load that should be managed by muscles is transferred to passive structures such as spinal discs, joints, and ligaments. Over time, this may increase the risk of strain, injury, and persistent discomfort.
Research suggests that core endurance – the ability to sustain low-level muscle activation over time — is particularly important for spinal health. Everyday activities like sitting, standing, and walking rely more on endurance than short bursts of strength (Hodges & Richardson, 1996; Abdelraouf & Abdel-aziem, 2016).
Reduced function of deep stabilising muscles such as the transverse abdominis and multifidus is also commonly associated with recurrent or persistent lower back pain (Hodges & Richardson, 1996).
Core Strength vs Core Stability: What’s the Difference?
There is a common misconception that core strength and core stability are the same — but they refer to different functions:
- Core strength: The ability of muscles to produce force
- Core stability: The ability to control and protect the spine during movement
For spinal health, stability and motor control are typically more important than strength alone.
This is why doing large volumes of crunches or sit-ups doesn’t necessarily improve back health. These exercises tend to target more superficial muscles and may not effectively train the deeper stabilising system.
Instead, effective core training focuses on control, coordination, and endurance (Coulombe et al., 2017).
Getting Started: Core Exercises Worth Knowing
If you’re looking to improve core function, these foundational exercises are commonly used:
- Dead bug: Encourages deep core activation while maintaining a neutral spine
- Bird dog: Activates the multifidus and improves coordination and balance
- Glute bridge: Strengthens the posterior chain, supporting spinal load distribution
- Plank: Builds endurance across global core muscles
- Pallof press: A functional anti-rotation exercise that challenges core stability
Technique is important. If you’re unsure where to start, professional guidance can help ensure the right muscles are being targeted effectively.
The Role of Chiropractic in Core Rehabilitation
Before core training can be fully effective, it’s important to address any underlying spinal dysfunction. Joint restriction, pain, or altered movement patterns can influence how well stabilising muscles activate.
Chiropractors assess how the spine and joints are moving, along with posture and overall movement patterns. Where appropriate, care may include manual therapy to address joint restrictions, alongside tailored rehabilitation exercises to improve muscle activation and coordination.
This combined approach – improving joint function while retraining muscle control – can be particularly helpful for individuals experiencing ongoing or recurrent back pain.
Your core is not simply about aesthetics – it is a complex, integrated system that plays a critical role in spinal health and overall movement.
Developing a strong core goes beyond building muscle strength. It involves improving stability, coordination, and endurance.
By focusing on proper core function, you may reduce strain on your spine, lower your risk of injury, and support long-term movement and performance.
If you’re experiencing lower back discomfort or want to improve your core function, consider reaching out to your nearest Total Health Chiropractic practice or a trusted healthcare professional.
A personalised assessment can help you better understand how your body is functioning and guide you towards an appropriate plan for your spinal health.
