Lesson 3: Core Stability (Prone Position)

To have good control of movement, we need to be able to stabilise our joints. Poor core stability means not being able to balance the muscles in our trunks, around our hips, and around our shoulders.


The following activities will help to improve your child’s ability to use the muscles that are involved in straightening the trunk.


Sea Lion

Ask your child lie on their stomach with legs straight and arms bent at right angles to the body on either side. Slowly ask them to lift their head until it is level with their back (only 4 -5 inches off the ground). The head should not be tilted back, if necessary an adult can place a hand at the top of their spine to let them ‘feel’ where the correct level is. Hold for x 3 building up to 5; then slowly let the head down to starting point. Repeat x 1 building up to x 5.



Have your child lie on their tummy with arms in front of them and then simultaneously raise their head, arms and legs off the ground. Legs should be kept straight. Encourage your child by saying  you’re flying like Superman”. Start with 5 seconds and work your way up to 20 seconds as your child’s strength increases.
