Why do we need a strong core?

By Ryan Byrne, Accredited Exercise Physiologist

Have you ever had a fall or worry about your balance? Do you have poor posture or experience lower back pain? Improving your core strength could help! The ‘core’ refers to the muscles located in the midsection of the body, including the abdomen, lower back, and hips. These muscles provide stability and support for various movements. (1)

Having a strong core is important for several reasons.

1. Stability and balance

Strong core muscles assist with stability and balance by providing a strong foundation for your body to move. Your core muscles work together to keep your trunk stable, which allows your arms and legs to move freely without throwing you off balance. When you have a strong core, you are less likely to fall over, and you can move with more control and precision. This is especially important during activities that require balance, such as walking on uneven terrain. A strong core is important for improving balance and falls prevention in older adults too. (2)

2. Injury prevention

A strong core can help prevent injuries by supporting the spine and reducing the stress on other parts of the body. This is especially important for people who perform physically demanding jobs or activities. (3)

3. Improved posture

If your core is weak it can contribute to poor posture, leading to chronic pain and discomfort. A strong core helps maintain good posture and reduce the risk of back pain. (2)

4. Daily activities

A strong core makes it easier to perform everyday activities such as lifting groceries, carrying children, and doing housework. It also makes it easier to maintain good posture while sitting at a desk or driving for long periods. (3)

5. Better physical performance

A strong core is essential for many athletic movements, such as running, jumping, and throwing. It allows for better transfer of power from the lower body to the upper body, leading to improved performance. (1)

What core exercises should I do?

Sit ups and crunches are not the answer. While both are effective exercises for strengthening the abdominal muscles, they are not always the best exercise choice because they can place excessive strain on your lower back and neck, potentially leading to discomfort or injury. While sit ups primarily target the abdominal muscles, they neglect other important core muscles, such as the deep stabilisers that support the spine. (2) These muscles are essential for stability and posture, so focusing solely on sit ups may not engage them effectively. There are many other exercises that improve core strength and stability without these limitations such as planks, squats and bridges. (2) You may need to speak with your local Exercise Physiologist, GP or Physiotherapist to work out which core exercises are best for you.
