I’m the ‘secret weapon’ of the  wealthy wives of Knightsbridge: They swear my pilates workouts keep their super-rich husbands faithful – try it for  yourself

The wealthy female clients of Knightsbridge-based Brazilian dynamic pilates instructor Juliana Campos call her their ‘secret weapon’. Thanks to her merciless training – ‘I focus a lot on the glutes with my ladies, everyone asks to improve their butt’ – they develop curves in the right places. Yes, you need a strong butt to protect your spine, but these women’s priority is securing their marriage.

And so they flock from their picture-perfect homes to Juliana’s cozy studio, a stone’s throw from Harrods, to learn how to arouse desire. “Looking their best is not just a goal, it’s a necessity, and for most, a means to maintaining their marriage,” she says. “Rich husbands are always a catch, and they all get a lot of attention from predatory women. The risk of being replaced and becoming the ex-wife is a clear and present danger.”

The mother of two adopts a daily regimen of booty-boosting Brazilian dynamic pilates

She says her clients tell her that “a toned and sculpted figure is the one thing about them that their husbands appreciate.”

“We have to keep ourselves young,” says Juliana in her delightful Brazilian accent. She has been a fitness instructor for more than 20 years, has taught pilates at the Lanesborough Hotel and worked as an in-house health advisor to members of Abu Dhabi’s royal family. She’s 46, a mother of two, and her daily regimen of booty-toning Brazilian dynamic pilates (focused more on progressive exercises and heavy glute work than classic) makes her look sensational.

“My clients and I always talk about the Marilyn Monroes in the neighborhood, all those young girls trying to attract men,” she says. Some are in the mood for a short fling or a sugar daddy treat. The more money they have, the more available these men are.’

As her clients tell her, “a muscular and sculpted figure is the one thing about them that their husbands appreciate,” so “pushing themselves to the absolute limits of discipline and effort is part of the price they pay to keep their husbands – and creating the most perfect and natural body possible is one thing that really keeps them in the game.”

Juliana says she also changes the mindset of women, giving them self-confidence and self-esteem

“Nothing keeps a man on his toes like when another man is paying attention,” says Juliana

After three months of twice-weekly sessions with Juliana, heads turn when her clients enter a room

This is survival of the fittest, Juliana warns. “Let age take over and these ladies know their husbands’ eyes and minds will wander.” One client, a mother of two in her mid-30s, was told by her husband that he “just didn’t find her as attractive as she used to.” He now saw her as a ‘mother’ and not as a lover – the inference was that perhaps he should look elsewhere for the latter.’

Fortunately, after three months of biweekly sessions with Juliana, heads turn when her clients enter a room. “There’s nothing that keeps a man on his toes more than when another man pays attention, and more than a few compliments to his woman,” she says. “I teach my clients not only to look their best, but to be their most desirable.”

Juliana says she also changes the mindset of these women, giving them self-confidence and self-esteem. Maybe instead of trying to hold on to these rich but sad-sounding men, some will leave them for the single life, or for someone who is kinder and more supportive.

‘I train my ladies to become strong for life. You may not care about your husband, but you are doing it for yourself,” she says

Juliana has created six of the best Brazilian dynamic pilates moves to perform at home

All you need are ankle weights, resistance bands, a squash ball, a mat for the sessions and the belief that anything is possible.

‘I train my ladies to become strong for life. You may not care about your husband, but you are doing it for yourself,” she says. So for any middle-aged woman who’s looking to feel good about herself and develop a kick to rival J-Lo’s, Juliana has created six of the best Brazilian dynamic pilates moves to perform at home. All you need are ankle weights, resistance bands, a sturdy pilates ball, a mat – and the belief that anything is possible.

Bottoms up for a peach backside

Lie on your back on the mat, facing the wall. Place your feet flat against it, your knees bent at 90 degrees. Keep your hips flat on the mat, in line with your knees. Rest your arms on the floor at your sides. Inhale to prepare, then exhale and lift your hips – so roll up from your tailbone, one vertebra at a time in a bridge, until you’re resting on your shoulder blades if you can – feel a nice hip extension. Contract your pelvis and slowly roll back down. We activate your glutes! Repeat ten – no! – 20 times.

What a nutter

Lie flat, in the same position, with feet flat against the wall at a 90-degree angle. Lift your hips and bridge. Straighten your left leg until it is vertical. Keep the other foot pressed against the wall. Keeping your hips level and your knees together, lift your left leg a few inches (don’t overextend), point your toes and hold, then lower your left leg and flex your left toes. Repeat this ten times and then switch sides. You should feel this in your core and glutes. Your core holds you in this position. Are you shaking? Wow – I’m sorry, but it will be worth it!

Brazilian ballet for your ass

Stand up and face the wall, pressing your hands against it. With your feet slightly wider than your hips, tuck your pelvis, inhale and squat down—like a plié—and exhale as you rise, lifting one leg out to the side, knee bent and toes pointed. Kick out – you work your quads and glutes. I hope you’re wearing ankle weights. You can start with 1 kg per ankle, but 2 kg is also fine. Repeat ten or twenty times on each side.

Totally awesome

Work on your abs now! This time you can wear those half-pound ankle weights on each wrist for more resistance. Sit on the floor, feet flat against the wall, knees bent at 90 degrees. Place the pilates ball under (or just above) your lower back. Then sit back and don’t lie all the time. Extend your arms horizontally in front of you, shoulder-width apart. Keep your torso long, lifting it up and down – look up at the ceiling, not the wall – you’re almost on your tailbone. Breath in breath out. To protect your back, make sure your abdominal muscles are engaged – imagine closing a zipper from your pelvic floor to your chest – keep it tight!

Get glutes like J-Lo!

Place 1-2 kilo weights on your ankles. Then start on all fours. Place your left forearm flat on the mat and we’ll do leg extensions. Place the Pilates ball behind your right knee and lift that leg until your thigh is horizontal and your knee is bent at 90 degrees. Tighten your abdominal muscles and your glutes. Then up and down. The higher you lift, the more effective it is for your glutes.

Keep going…

No, you still haven’t done enough. Get down on all fours. With your left forearm resting on the floor and your right arm extended, touch your right leg to your right elbow. Make sure you wear your ankle weights! Keep your knees hip-width apart. Repeat ten times. Now ten more, quick! Now straighten the leg (so that it is vertical) and make ten small circles in the air. And vice-versa. Do you want to do the other leg? I hope so! In Brazil the girls do this with 10k weights. It’s all about the loot there!

Check with your doctor before starting a new exercise regimen.
