They're back and they're just as desperate as ever - but not when it comes to looking sexy. We've lifted the lid on each of their diet and exercise regimes, to reveal how they keep looking the part of the sexiest women on television. So if you're desperate to be an Eva diva, a Teri temptress or even a yummy mummy like Marcia, here's how they do it - and how you can too

Teri Hatcher
Age: 41
Dress size: 6
Housewife workout: Yoga, hiking and stripping! While Teri's fame has grown since her debut on Wisteria Lane as bungling single mum Susan Mayer, the actress herself has got smaller and smaller in stature. The 41-year-old real-life single parent has suffered from eating disorders in the past but she insists her stick-thin figure is now down to nothing more than exercise. 'I like to hike and work out at the gym but I get bored easily,' says Teri. 'That's when I started doing the stripping classes. It's very much about empowerment and women of all sizes do it. There are no mirrors and nobody cares what you look like. It's just all about being comfortable with your body.' Teri's saucy way to stay fit involves an hour of Pilates and yoga-style stretching exercises, followed by 30 minutes of pole- or lap dancing - and normally without a man in sight! 'It's not about turning a guy on,' explains Teri, 'it's about turning yourself on and feeling good about yourself.'
Desperate diet: Teri eats low fat but high protein meals like grilled chicken or steamed fish with fresh vegetables. She does still have room for a sweet tooth in that tiny body of hers. 'Banana splits with chocolate and gummy bears is my big weakness,' she confesses.

Eva Longoria
Age: 30
Dress size: 6
Housewife workout: Kick-boxing She might be a skinny 5ft 6ins but Eva is pound-for-pound almost as tough as her basketballer boyfriend Tony Parker. Ever since Eva found out just how much exposure she was in for playing sex-mad Gabrielle Solis, she has been literally fighting to look her best. 'I had never really worked out before but when I found out I would be in little more than a bra and panties on the show I went straight out and got myself a personal trainer,' says Eva. 'I do kick-boxing a couple of time a week and then the rest of the time I do yoga, stairs and a little weight training. But I'm lucky because I don't put on weight very easily.'
Desperate diet: It's sickening, but Eva doesn't have to diet to look good. 'The great thing is that I can eat what I want,' she says. 'I love spaghetti with meatballs - that's my favourite.'

Marcia Cross
Age: 43
Dress size: 8
Housewife workout: Yoga, yoga and more yoga! Being fit is a lifestyle rather than fad for ravishing redhead Marcia. 'You won't find me out at night in a bar or at a restaurant,' says Marcia, who plays the prim and proper Bree Van Der Kamp. 'Instead, I'll be at a chant or a yoga retreat.' Marcia has used yoga, specifically Iyengar yoga, to keep her willowy figure since long before it was trendy in Hollywood to contort yourself on a mat. Before filming started on season two of Desperate Housewives she added a little extra tone to her figure with some hill walking. And she has another reason to keep up her routine - she's about to be married to stockbroker Tom Mahoney. The couple, who have been an item for a year, are expected to tie the knot in the summer.
Desperate diet: Marcia keeps to low fat foods but sadly she's not so good at cooking them as she is eating them. 'I love to eat but I'm useless at cooking,' she confesses. 'I'm dreadful in the kitchen.'

Felicity Huffman
Age: 43
Dress size: 8
Housewife workout: Tennis, cycling and motherhood! Just like her character on screen, desperately harassed mum Lynette, Felicity gets plenty of exercise chasing after her two children with actor husband William H Macy. While she's naturally fit from a childhood filled with skiing in the Colorado mountains, she can't help but look upon some of her fellow housewives a little enviously. 'Both Eva and Teri have such amazing figures, and so does Marcia,' says Felicity. '(they) get to wear great clothes so they need the figure. My character wears pyjamas and morning shirts, so I can get away with it.' But the actress does find some time to burn calories 'I play tennis and I go biking and hiking,' she says. 'I love the outdoors.'
Desperate diet: Felicity insists on a balanced diet, not just for the sake of her figure but also her family. 'We eat well and healthily,' she says. 'I insist on it.'

Nicollette Sheridan
Age: 42
Dress size: 8
Housewife workout: Gym, horse riding, volleyball, nude housework! Nicollette's body has barely ever seen a bulge or a sag. She has been horse riding since she was three and has thrown herself at almost every other sport since. Roles in movies like Beverly Hills Ninja saw Nic train in martial arts and she can still pack a punch to stave of the effects of lunch. 'I like being active,' she says. 'I like sports and I go to the gym as much as I can.' And even when Nic is home she has found a way to keep fit - naked housework. 'It's a normal thing for me to do,' she says.
Desperate diet: If there are any feuds among the housewives (which there aren't, according to the girls) it's Nic who has an axe to grind the most. Her cravings for junk food are not helped by Teri bringing all kinds of naughty treats on to the set for cast and crew. 'I love eating pizza and French fries,' says British-born Nic. 'I'm always on at Teri to stop bringing that in. Otherwise, I really try to watch what I eat. I love fresh fruit and vegetables.'
