Understanding Core Strength

23 May 2024

Core strength refers to the strength of the muscles in your trunk/ midsection, this includes your abdomen, spine, lower back, and pelvis. These muscles are crucial for maintaining stability, balance, and overall functional movement.

Components of the Core

  1. Abdominal Muscles:
    • Rectus Abdominis: Often referred to as the “six-pack” these are the muscles that run along the front of your abdomen.
    • Transversus Abdominis: The deep muscles that wrap around your spine for stability. These muscles stabilise the spine and hips, allowing us to stand tall and straight.
    • Internal and External Obliques: Muscles on the sides of your abdomen that help with rotation and side-bending. The oblique muscle to twist from side to side.
  1. Lower Back Muscles:
    • Erector Spinae: A group of muscles running along your spine that help with strong posture and the ability to perform back extension. These muscles along with Transverse Abdominis and Hip Flexors allow us to raise our legs straight.
  1. Pelvic Floor Muscles:
    • These muscles support the bladder, intestines, and for women, the uterus. When these muscles weaken and become lax a person may find themselves suffer urinary incontinence, the overall health and strength of the pelvic can have a huge impact on us as we age. 
  1. Hip Muscles:
    • Hip Flexors: Muscles at the front of the hip that lift your leg with the assistance of the Erector Spinae & Transverse Abdominis
  • Gluteal Muscles: Muscles in your buttocks that help with hip movement and stability. These are the largest muscles in the human body, made up of a group three muscles Gluteus Minimus, Gluteus Medius, Gluteus Maximus. Functions of the glutes collectively include:
  • Stabilization: The gluteal muscles play a crucial role in stabilizing the pelvis and maintaining proper alignment of the hips and lower back during various movements.
  • Posture: Strong glutes contribute to good posture by providing support to the pelvis and spine.
  • Power Generation: These muscles are involved in generating power and force during activities like walking, running, jumping, and lifting.
  • Balance and Coordination: Gluteal muscles contribute to balance and coordination by stabilizing the body during dynamic movements and preventing excessive hip movement.

Overall, the gluteal muscles are essential for various functional movements, including walking, running, sitting, standing, and performing activities of daily living. Strengthening and conditioning these muscles can help improve performance, reduce the risk of injury, and enhance overall lower body function.

Why Core Strength is Important

  1. Stability and Balance:
    • A strong core helps keep your body stable and balanced during movement and while standing still.
  1. Improved Posture:
    • Core muscles support your spine, helping you maintain good posture and reducing the risk of back pain.
  1. Enhanced Athletic Performance:
    • Many sports and physical activities depend on a strong core for power and efficiency.
  1. Injury Prevention:
    • A strong core can help prevent injuries by providing better support and stability to your body during activities.
  1. Daily Functional Movements:
    • Everyday activities like bending, lifting, and twisting rely on a strong core for ease and safety.

Exercises to Improve Core Strength

  1. Planks:
    • Hold your body in a straight line, supported by your forearms and toes. This engages multiple core muscles at once.
  1. Sit-Ups and Crunches:
    • Traditional exercises that target the abdominal muscles.
  1. Russian Twists:
    • Sit with your knees bent, lean back slightly, and twist your torso from side to side.
  1. Leg Raises:
    • Lie on your back and lift your legs without bending your knees, targeting the lower abdominal muscles.
  1. Bird-Dog:
    • On your hands and knees, extend one arm and the opposite leg, then switch. This exercise enhances balance and stability.
  1. Bridges:
    • Lie on your back with knees bent and feet flat. Lift your hips towards the ceiling, squeezing your glutes and engaging your core.


Core strength is essential for overall body stability, balance, and functional movement. It involves the muscles in your abdomen, lower back, pelvis, and hips. Strengthening these muscles improves posture, athletic performance, and daily movement efficiency while reducing the risk of injuries. Incorporating core exercises like planks, sit-ups, and leg raises into your fitness routine can significantly enhance core strength and overall physical health.
