Stand up straight facing a wall.
Bend your elbows and place your forearms against the wall.
Your elbows should be at shoulder height and your forearms pointing vertically up the wall.
Leaning onto your forearms, keep your shoulders strong.
Drive your elbows into the wall so that your shoulder blades do not stick out.
Keeping your body straight, walk your feet backward from the wall.
Ensure your hips do not push out behind you.
Hold this position at a point you are able to keep your body in line with your legs.
You should feel the effort in your tummy muscles and around your shoulders.
