Jennifer Lopez is quite literally the Benjamin Button of the modern universe. In August, we celebrated her 20-year tenure at the top of the music charts at the MTV Video Music Awards but looking back at the crops, the hoops and the handkerchief bandanas, it appears the Bronx native’s body is actually in the best shape of her life at the age of 49. “I see pictures of myself in my twenties and go ‘Oh, I look better now!’ I embrace who I am. I feel sexy, I feel youthful, I feel pretty sometimes,” Lopez told US Weekly. I’ve taken care of myself, and now it shows,” she told People.

Amongst the diet omissions and strenuous workouts, Lopez credits age and perspective on giving her the confidence to be really secure within her own skin. “Women get more confident as they get older,” she told W magazine. “Men in their 20s are very confident and cocky, and women are super insecure. And then it flips: Men get super insecure, and women get comfortable in their own skin, in a way that makes them more beautiful.”

As Lopez is set to release her new Manhattan-set romantic comedy, Second Act, her age-less physique is at the top of the press pile again. For it too is taking a second bow of its own. So how does she do it? Here’s everything we know by way of a compilation of interviews over the years.

She gets 8-10 hours sleep a night

Without a full night’s sleep, Lopez says she feels crazy, emotional and tired all of the time. “The number one tip is to always get enough sleep,” Lopez told InStyle US. “I can’t stress this enough. Ideally I would love to get nine or 10 hours of sleep, but either way, I always make sure I get at least eight.” Her boyfriend, former American baseball player Alex Rodrigues concurs. “[Lopez] really leans in to the big fundamentals, he told Harper’s Bazaar. “Like getting her rest, eight to 10 hours. She doesn’t drink, doesn’t smoke. She lives a very clean life.”

She also doesn’t drink coffee

A huge difference in Lopez’s lifestyle compared to the average Australian is the little luxuries she omits from her life: Alcohol, smoking and drinking are off limits (she sips decaf in the morning). Even after the superstar was honoured with the 2018 VMA’s Vanguard Award, she put her children to bed and went to her own after party at Beauty & Essex on New York’s Lower East Side and reportedly didn’t consume a single drop of champagne. “I don’t drink or smoke or have caffeine,” she’s admitted.“That really wrecks your skin as you get older.”

Her green vegetable intake is huge

“We eat a lot of green vegetables, asparagus, Brussel sprouts, broccoli and kale,” she told The Independent of her eating habits with her children. “I love to cook a lot of stuff, I love cooking Puerto Rican food because that’s what I grew up on.” This includes a lot of pork and chicken and if she’s out at a restaurant, Lopez will order fish and veggies. “I do try to eat right,” she told People. “And I don’t always want to.”

She strictly works out at least five days a week

Remember Lopez just wound up a three-year Vegas residency calling for her to work out in the morning and then perform on stage at night. This was when we began to see her body really change and her muscles really become defined. And today, the strength of her body is one of the most appealing parts of the singer. In order to achieve this, Lopez has a trainer on each coast; Tracy Anderson in Los Angeles and David Kirsch in New York. Her one consistent, however, is he boyfriend. “We work out together all the time,” Rodriguez told E News!. “[Lopez] is a fitness enthusiast and she’s a much better athlete than me. She does all types of workouts which I don’t try to keep up.” But Lopez admits it’s not always easy to get up and go and train. “Very rarely will I skip my workout,” she told US Weekly. “Sometimes, I work too late the night before, and I’m like, ‘Ugh, I can’t do this.’ But I tell myself, ‘Just do it. It’s only an hour.’ It’s just talking yourself off the ledge of being a lazy bum.”

She counts her blessings

From her little family home in The Bronx to the bright lights of Uptown, Lopez – while a firm believer in hard work – isn’t cocky in her achievements. Every morning she begins with a mediation session and credits this – (and staying out of the sun) – for her youthful looks. “I also definitely think beauty comes from within – you have to have keep your mind, soul, body and spirit in sync,” she told InStyle US. “I am a firm believer in meditating and when you are happy and feel joy and love, you radiate beauty.”

Second Act is in Australian cinemas now.
