Kerr was posing in a bikini and white crocheted dress for the launch of Victoria Secret’s swimwear collection. She is certainly a new body idol to aspire to – There was not a protruding collar bone insight – instead she was championing a hot new body shape – strong, womanly, curvy and above all, healthy!Bet this will surprise you – time to put on weight, ladies! The right way. This means forgetting about BMI and thinking about BPI – Body Power Index. The look is about ‘feminine bulk’ – toned abs and curves to boot.

‘This look is definitely achieved by adding resistance training to a workout,’ says celebrity trainer James King (jameskingperformance.com).

‘Lifting weights gives you a metabolic pump that can last for up to 36 hours after a workout while your body repairs and super-compensates for the next challenge.

That means you’ll fry up to 25% of the calories you just scorched during your strength session,’ King says. So technically, if you burned 300 calories lifting weights, it’s really closer to 400 overall. Suddenly, dumbbells sound like a smart idea! Ok not that I’ve always lamented but I actually like doing weights. Feeling the ache and pains afterwards = REAL work has been done!

Do you have to catch your breath everytime you look at her picture?

I do.

Now, get crackin’:

‘There’s even more good news when it comes to adding weights to your workout’, says King. ‘For every three pounds of muscle you build, you’ll burn an extra 150-200 calories a day at rest- even when you are doing nothing because muscle is literally sustained by fat.’

So technically that is 10 pounds of fat lost over a year without even changing your diet. How to say no?!

Miranda has obliques to die for. Dieters trying to achieve a stomach like this are probably cutting back on crucial muscle-maintaining foods when they slash their overall calorie intake.

The counterproductive result: they lose muscle along with any fat that might have melted away. So make sure you are adding high-quality protein into your diet, ‘the sources are chicken or other lean meats, soy products and eggs,’ says personal trainer Nick Cole (powerflexstudios.co.uk).

‘Target your arms, abs, legs, and back, and go for compound moves that will zap several different muscle groups at a time – for example, squats, which call on muscles in both the front and back of your legs as well as your back and abs, opposed to exercises which isolate muscles,’ says King. Full-body weight workouts are the biggest calorie burner.

My favourite outfit of the lot – she looks like a goddess!

‘Not looking at the scales is a good attitude to have when it comes to weight loss,’ says Cole. ‘If you are doing weight training, remember muscle is denser than fat, so don’t concentrate on the scales dropping as they actually might not – instead concentrate on fitting into smaller sizes.’

Miranda has gone from super slim to super toned.. ‘Try making your exercise regime old school and incorporate kettlebells and barbells into your workout’, advises King.

There’s a longer-term benefit to all that lifting, too: Muscle accounts for about a third of the average woman’s weight, so it has a profound effect on her metabolism – muscle, unlike fat, is metabolically active meaning it chews up calories even when you are not in the gym.

Miranda bucks the trend in the modelling world: instead of being stick-thin, she is still very slim but also has curves in the right places. ‘Strength training has definitely helped her curves,’ says Cole.

‘It really is beneficial and an added bonus is not only does it create enviable curves but it also helps increase bone density and lowers your risk of developing osteoporosis.’
