And the secret to good posture is balance. But don’t worry. I won’t be asking you to do any ballet. Instead, I want each of you to back up against the wall with your heels, upper back, head and shoulders touching the wall.’ As I stood against the wall in my Jimmys, I stared at myself in the mirror. I looked a bit like my mum, besuited and heeled. Brie walked over to each of us in turn, correcting our postures. ‘Keep your feet parallel, draw your abdomen in, move your back closer to the wall, lift your chest and keep your shoulders back. India, try to increase the gap between your shoulders and your hips as much as you can. Darcy, pull your chin back and raise your head.’ Brie positioned Darcy so that her head was in the right place. ‘That’s much better. A rounded back, sagging shoulders and drooping chin is never attractive. Plus, it makes you appear ten years older.’ Wow, standing like a stem actually made my boobs look bigger. I’d never really thought about my posture before.
