Get fit like Rosie with Bodyism's 5-step catwalk-prep

Fashion week is coming... Are you ready? We asked the guys at Bodyism to share their tips model use to get prepped for the catwalk.

Exercise One
Standing Weighted Ws
To achieve perfectly sculpted arms & back
How to? Stand bent over at the waist with your back flat and chest up, with feet shoulder width apart.
Draw your shoulder blades back and down and lift your elbows to the sky as they bend to 90 degrees, and rotate your hands to the sky in line with your ears...
Exercise One
Raise your arms above your head, palms facing forwards.
Reverse the steps back to the start position.
Reps: 20 times.
Exercise Two
Side Leg Raise With Band
Make like the Victoria's Secret Angels, and tone the thigh and hip region
How to? Take a Bodyism mini band of your chosen strength - we have used middle strength here - and place it just above your ankles...
Exercise Two
Stand with perfect posture, and setting your core, raise one leg out to the side of your body as high as you can go without leaning in the opposite direction.
Slowly lower the leg back to the start position.
*If you find yourself leaning over or feeling pressure in your lower back, take the exercise to the floor lying on your side.
Reps: 20 times on each leg.

Exercise Three
Deep Side Lunge
Maintain a statuesque physique à la Gisele
How to? Begin standing in an upright position, with feet together and perfect posture. Begin with both hands on your hips...
Exercise Three
Set your core and step sideways into a deep lunge. As you lunge, push your butt out to the side.

Exercise Three
Push up back to the start position through your heel to keep the butt working, returning your leg to a standing position and your arms on your hips.
Reps: 15 times on each side.
Exercise Four
Abdominal Leg Lowering
Rosie Huntington-Whiteley, Cara Delevingne, Jourdan Dunn - they've all got great abs. Get 'em this way...
How to? Lie on your back with your legs straight up in front of your at fright angles to the floor.
Slowly tighten your abs and rotate your pelvis slightly back and down.

Exercise Four
Slowly lower one leg, so the thigh is perpendicular to the floor then switch legs.
*If your lower back hurts, bend the legs at the knees and continue the same movement pattern - if it still hurts then stop.
Amp it up: To progress, lower both legs at the same time.
Reps: 10 times on each side or 20 times in total.
Exercise Five
Lying Swimmers
Walk tall with runway ready posture
How to? Lay on your front, hand out above your head, palms facing downwards.
Raise your hand and feet slightly off the floor, keeping your neck and back in perfect alignment...
Exercise Five
Lower your arms all the way down alongside your body and pause for one-second before returning to the start position (click on to see end position).
Reps: 20 times
Exercise Five
Get the most out of your workout by following the 10 second rule: Stand up straight, keep your back straight with your ears over your shoulders and your shoulders over your hips. Look straight ahead and think tall, right through your spine and through the top of your head.
