When I hear the words “strengthening core muscles for children” my initial thought is “what! really?” To me this concept seemed a little nuts! Surely kids are naturally developing these muscles as they play? I had to think about this long and hard and then came to the realization, after talking to Paediatric Physiotherapist Nicole Hilburn, that your core muscles play a vital role in the functioning of the body and can directly affect learning.


I always want to give my kids the best start to their health, setting a standard for them to carry through to adulthood. So why not build on this and do some activities that strengthen their core while having fun?




Here is what Nicole said about core muscle strength and the activities that she suggested we try:


What are your core muscles?


These are the muscles that act to stabilise your spine and maintain posture – in broad terms, the muscles of your pelvis, hips, abdomen and lower back, as well as the shoulders.


The muscles of the abdomen and back need to work together in order to stabilise the core. The more you move, the faster you move, the more stability you need from your core muscles to support you. Your core muscles should allow you to carry out daily tasks with minimal effort and no strain on your body.


Why are your core muscles important?


Your core muscles help to support your body and allow a child to use his/her arms and legs strongly and effectively. Strong core muscles form the foundation for good posture, coordination and balance. All gross and fine motor skills rely on a stable core and so it makes sense that we encourage our children to get out there, get fit and exercise.




How does poor core stability affect learning and later sports skills?


A child who is sitting at a desk needs their core muscles to support them so that they are able to stay upright against gravity and use their eyes or hands effectively. A child with poor core stability will be using other ways of keeping themselves up against gravity which are often ineffective and tiring, and will therefore either lose focus as a result, or their fine motor output will be poor.


When it comes to the sports field, children with poor core stability cannot use their arms and legs efficiently, or find other ways of compensating. They may experience poor coordination and fatigue as a result, making sports activities difficult and frustrating for them.


What are the signs of poor core strength?


  1. Poor posture such as rounded shoulders, pigeon-toed feet, and leaning on the insides of the feet
  2. Heavy movements when running, jumping and hopping
  3. Signs of trying to find stability when having to stand or sit still
  4. Poor gross motor skills and clumsiness – may fall often
  5. Difficulty climbing, and playing on unstable equipment such as bikes
  6. Tires easily when walking for a longer period of time, and may ask to be picked up


Fun games and activities which help to improve core stability:


Wheelbarrow walks

This is a great activity for trunk and shoulder girdle strength. Hold the child at the ankles, or if they struggle, then hold under the thighs.


Try and go up and down the passage/across the garden a few times. The tummy should not sag, and you should not be able to see your child’s shoulder blades sticking out – if either happens, hold under the thighs or closer to the body.




This activity strengthens the trunk and shoulder girdle, and is fun for all ages. Get your child to make a bridge with his body by bending over backwards. Roll a ball underneath and see how long he can stay up for!


Drawing under a table

This is a great activity for shoulder girdle strength. Tape a piece of paper to the underside of a children’s table. Let your child draw whilst lying on his back!


Crab walks

Get your child to sit on the ground with his/her knees bent, the hands should be placed on the ground behind/ him/her, lift the bum off the ground to create an arch way. This activity strengthens the muscles of the back and pelvis. Just holding the position is also great – you can pretend something is walking underneath the bridge.




Throwing a ball

Get your child to throw a ball from above his head. He can also bash the ball back to you. Holding the arms up strengthens the shoulder girdle, and the muscles of the back.


General strengthening activities:


  1. Swimming
  2. Climbing a jungle gym
  3. Monkey bars (from about 4 years)
  4. Fireman’s pole (from about 4 years)
  5. Jumping on a trampoline




When should you consult a physiotherapist?


A child who shows signs of poor core stability may benefit from a referral to physiotherapy when:


  1. Not coping with activities which are age appropriate at school
  2. Avoiding activities such as climbing on playground equipment or riding bikes
  3. Poor socialising skills due to an inability to keep up with peers
  4. Chooses more sedentary activities rather than running around or moves constantly and will not sit down for any length of time to do an activity
  5. Fidgets constantly
  6. Poor fine motor skills
  7. Cannot grade drawing skills – presses very hard, and uses an immature grip
  8. Possible poor speech
  9. Tires easily


A cluster of these signs and symptoms may indicate that a child has poor core stability. Sometimes, extramural activities which are known to be good for strength are not enough, as a child who is weak will use compensatory strategies to do an activity, and overuses strong muscles, and underuses weak muscles. Therefore the extramural may not be strengthening the correct muscle groups, and one on one physio may be required to identify and strengthen the correct muscle groups so that a child is able to participate in all activities appropriate for his/her age with minimal effort, and is able to reach his/her full potential at school.


So here I go! I’m out there with my kids playing games and having fun, while strengthening their core, as well as mine.
