Stand with your feet almost shoulder-width apart, toes facing forwards and slightly out. Tilt your backside out slightly keeping your lower back arched. Pull your belly button in towards the spine. With the broomstick resting on your upper back and shoulders, stick your chest out so your shoulder blades go down and in towards each other. Try to keep your tongue on the roof of your mouth to activate the neck's stabiliser muscles.

From this starting position sit down into a squat. Your trunk should lean forwards a little, but not so much that your lower back slouches. Keep your feet flat and spread the weight evenly. Do not let your knees collapse inward. Descend as low as you can without losing the arch in the lower back. Press through your feet to return to the starting position and repeat.
