Kneel on a mat with a stable surface in front of you around waist height.
Place both of your hands on the surface.
Extend through your hips so that your body is up tall.
Your shoulders, hips and knees should be in alignment.
Lift one leg and place it slightly to your side, then bring your other leg to meet it.
Continue walking your knees sideways along the mat, following with your hands on the surface.
You should aim to remain as tall as possible during the exercise and keep your shoulders level.
Once you reach the end of the mat, continue in the opposite direction.
