Guns blazing

Brilliant biceps
Jen Aniston credits her toned arms to Budoken Yoga, combined with intensive cardio sessions. She starts her workout with a 22-minute cardio warm-up, followed by weight training to prepare her muscles for all that bending and stretching.

Make it work for you:
Blitz the treadmill for 15 minutes at a 9 kilometres per hour pace on a 1.5 incline. When you're finished, complete five Sun Salutations to get your breath back.

Perfect package

Top to bottom
Whilst we unfortunately can't steal Gisele's enviable genes, we can certainly copy her exercise secrets. A self-confessed yoga addict, the Brazilian beauty rolls straight out of bed onto the yoga mat before breakfast. An outdoorsy girl, her perky behind is the result of combining yoga workouts with horse riding, volleyball and extreme sports, which she counts amongst one of her favourite hobbies.

Make it work for you:
Squats and lunges are the best exercise to help define your derriere. For optimum results, hold dumbbells in your hands for extra resistance, and do three sets of 10 reps.

Winning by a leg

Perfect pins
Desperate to discover the secret of Gwyneth Paltrow's lithe legs? Although she says she forces herself to work out as soon as she wakes up, she confesses, "I'm really not a morning person at all, I'm very strict with myself. It's just sheer determination."

The mum-of-two wakes up at 4.30am to work out when her alertness and energy levels are at their peak - and exercising in the morning is a great way to rev up the metabolism.

Make it work for you:
Can't face getting up at the crack of dawn? Put out your workout clothes the night before and have your exercise equipment all lined up in front of your bedroom door - you'll have to climb over it to get out the next morning.

Stomach this

Fab abs
Definitely not a workout for the faint-hearted, Madonna starts her day with a three-hour session of tummy-toning Ashtanga yoga followed by pilates, karate, swimming or weights, followed by running, cycling or horse riding!

Make it work for you:
Do just 20 minutes of cardio followed by stomach crunches and oblique twists three or four times a week and tone up in weeks.
