Come into an all fours position with your hands under your shoulders and your knees under your hips. Brace your core and maintain a flat back as you lift your knees a few inches off the floor and move your feet back an inch. This is your start position. Twist your right hip down towards the floor and kick your right leg under and through to your left side. As you do this simultaneously bring your left arm away from the floor and touch your hand to your temple. Reverse the movement to return to the start position, then repeat the same sequence on the opposite side. Continue this pattern for the required amount of time.
