At Bodyism, located in the brand new Bulgari Hotel in Knightsbridge, Duigan and his team specialise in getting their clients a long, lean, athletic body through exercise and diet as well as supplements - all designed to strip fat, boost health, improve posture and generally get you as fit as you can be. And really, who doesn’t want a figure like Rosie’s?

Now we can’t all pop in for a personal training session with Duigan, so now is your chance to get your questions answered. Whether you want diet tips, exercise tricks or don’t know which supplements you should be popping, then log on to Twitter this Thursday at 1pm and tweet James Duigan with your questions @ELLEUK.
