Start on your hands and knees with your hands under your shoulders and knees under your hips.
Find your neutral position with your spine and head.
Push the heels of your hands into the floor so that your shoulder blades flatten against your back.
Tighten your abdominal muscles to help stabilise your trunk as you bring one knee in towards your chest.
Do not allow your hips to rotate with this movement.
Maintain the same neutral posture with your spine and head as you move your leg.
Next, control the movement as you straighten the same leg out behind you.
Ensure your back and neck remain in the neutral position throughout with your shoulder blades controlled.
Repeat.
