The core is more than just the “abs” we often think about—it’s a deep, multi-layered system of muscles that stabilises the body and supports almost every movement we make. Whether running, cycling, swimming, or sitting at a desk, your core maintains posture, balance, and efficient movement patterns.
The four key layers of the core work together to create strength, stability, and power:
Rectus Abdominis—This is the most superficial layer, often called the "six-pack" muscle. It helps with forward bending (spinal flexion), but it can create excessive strain on the lower back without support from the deeper layers.
External Obliques – These run diagonally along the sides of the abdomen, helping with twisting movements and lateral stability, crucial in sports like golf, tennis, and swimming.
Internal Obliques – Located beneath the external obliques, these provide deeper support for rotation and side bending, which is key in controlling movement and preventing injury.
Transverse Abdominis (TVA) – The deepest core muscle, wrapping around the abdomen like a corset. It stabilises the spine and pelvis and is the foundation of all functional movement. Activating the TVA properly reduces the risk of back pain and injury.
Why a Strong Core Matters for Sport & Everyday Life
A weak core can lead to poor posture, inefficient movement, and increased risk of injury. Conversely, a strong core offers several key benefits:
✅ Stability & Balance: Whether you’re balancing on a surfboard, running on uneven terrain, or changing direction quickly in sports, a strong core keeps you stable and controlled.
✅ Power & Efficiency: Every explosive movement—whether sprinting, jumping, or cycling—generates force from the core. A weak core means wasted energy, reducing endurance and power output.
✅ Injury Prevention: A strong core supports the lower back, hips, and knees, reducing stress on these areas and preventing common overuse injuries in runners, cyclists, and swimmers.
✅ Better Posture & Breathing: A strong core maintains spinal alignment, helping with efficient breathing, reducing fatigue, and improving overall endurance.
The Importance of Breathing While Engaging the Core
Many people mistakenly "hold their breath" when engaging their core, which can limit oxygen supply, increase tension, and reduce endurance. In contrast, learning to breathe while maintaining core activation enhances both strength and relaxation.
🔹 In Yoga & Sport: Coordinating breath with movement (like exhaling during exertion) improves efficiency, steadiness, and endurance.
🔹 For Injury Prevention: Proper breath control prevents overuse of secondary muscles (like the shoulders and neck) and encourages deep diaphragmatic breathing, which engages the transverse abdominis and stabilises the spine.
🔹 In Practical Terms: Instead of sucking in the belly, we aim for a gentle “hugging in” or bracing of the core while keeping the breath steady—allowing movement without tension.
Bringing It to the Mat – Yoga for Core Strength & Breath Control
The following are common core-engaging poses that you might be familiar with:
🔹 Plank Pose (Phalakasana or Kumbhakasana) – Engages all four layers of the core while maintaining a steady breath.
🔹 Boat Pose (Navasana) – Strengthens the deep core and hip flexors whilst challenging balance and stability.
🔹 Twisting Poses (e.g., Revolved Chair Pose, Revolved Triangle or Revolved Lunge) – Twisting postures target the obliques and help maintain control in rotation-based sports such as golf and tennis.
By incorporating intentional core engagement with smooth, steady breathing, athletes can train their bodies to perform with greater strength, endurance, and efficiency—both in sport and in life.
