Core strength does not sound like something that should affect everyday childhood, but it plays a surprisingly important role. A stable core helps children sit upright, balance, run, climb, and control their arms and hands during activities such as writing.
Signs of a Weak Core
● Slouching or leaning while sitting, even in a supportive chair
● Tiring quickly during physical activity
● Difficulty with activities like climbing or running
● Using arms to prop themselves up while sitting on the floor
A weak core often shows up in unexpected places — like messy handwriting or trouble sitting still at a desk, since a stable trunk is needed to steady the arms for fine motor tasks too.
What Can Cause It
● Low muscle tone
● Limited physical activity or floor time as an infant
● Underlying developmental conditions affecting overall strength
Simple Activities That Build Core Strength
● Tummy time-style games for younger children
● Animal walks (bear crawl, crab walk)
● Balancing on a therapy ball with support
● Simple yoga poses like "superman" or "plank" adapted for kids
You do not need to turn these activities into formal exercises. Children can build strength through games, movement, and short bursts of activity throughout the day.
If your child tires quickly, frequently slouches, or finds activities requiring trunk stability unusually difficult, an occupational or physical therapist can assess their core strength and suggest activities that fit naturally into your routine.
