How J.Lo Maintains Her Amazing Physique

Jennifer Lopez does not age. The multi-talented entertainer, who has made a real name for herself as both a singer and an actress, was born in the Bronx on July 24, 1969, which is seriously hard to believe. From her roles in blockbuster films such as 1997's Selena to her chart-topping records, like 2001's J.Lo, Lopez has been in the spotlight for over two decades and she continues to wow with her talent and her beauty. So how does she do it? How does the mom of twins maintain her amazing physique year after year? We dug deep to uncover eight of her biggest tricks to diet and exercise success.

"I'm 100 percent convinced that working out is part of what makes me so happy," Lopez told Daily Star. "Dance has always been a huge part of my life, and taking the time to move my body and do something that's so good for me is key to my happiness."

"Sometimes, when I get home and I'm not feeling so great, I make myself go to the gym," she declared in an interview with Redbook in 2010. "Then I come home and take a shower, put on a great outfit, some makeup, tie my hair up, and I feel pepped up and great about myself. I think that for some reason, when you maintain yourself, people are really surprised. It's inspiring for women who have kids and take care of themselves to be sexy."

In an interview with The Independent, Lopez was very adamant in telling fans: "I don't drink, I don't like the taste, and I've never done drugs either." Looking back to the early days of her career during a chat with Today, she seconded that thought, saying, "I always used to hear this saying, until you're about 25 or 30, you get the face God gave you," she continued. "After that, you get the face you deserve. And I always kind of thought, well I better be nice."

The diva also stays far away from caffeine. Cutting out coffee may seem extreme, but the Mayo Clinic reveals that consuming too much caffeine can have serious side effects, including "insomnia, nervousness, restlessness, irritability, an upset stomach, a fast heartbeat and even muscle tremors."

"Just like anybody else, there are days I feel great when I wake up, and then there are days when I feel more tired or not ready to face the day," Lopez said in a candid talk with Elle Canada. "To be quite honest, on those days, I really try to think positively. I try to do a lot of affirmations for good health and positive thinking to just get my mind and my spirit in the right place so I can face whatever it is that I need to face."

"Feeling beautiful is an attitude," she added when speaking with The Mirror. "And we should all look for the beautiful things we love about ourselves, regardless of how our bodies compare to someone else."

Equally important is the fact that Lopez applies this positive outlook to her body image, no matter what her weight may be at any particular time. "I remember when I had baby fat and my thighs were so out of proportion to my ankles," she told The Telegraph. "Then I remember dropping weight and being quite thin. Then, when I got pregnant, I remember watching my back, belly and butt grow and thinking, 'I will never be the same again.' Then I remember right after the twins were born having that weird jiggly belly — and kind of loving that, too. Because I earned that jiggly belly. Then came trying to get my body back into shape and how long that took. A whole year."

Speaking with Us Weekly, (via Hollywood Life), Lopez gave fans some serious insight into her diet plan and, as you might imagine, it's quite strict. Lopez starts the day off with a chocolate-flavored BodyLab Shake made with either quinoa milk or water, which clocks in at just 90 calories. She admitted, "By lunchtime, I'm starving." A veggie and salmon salad is her go-to and usually includes "broccoli, peppers and zucchini with a drizzle of vinaigrette on top." Then it's on to dinner, usually around 6:30 p.m., which she said involves lots of protein and quinoa. "It feels like rice and beans, which I grew up with," she told the mag. "And I like pork and chicken, especially Puerto Rican style!"

And when it comes to snack cravings, Lopez has a trick for beating those too! Speaking with Daily Star, she said: "Protein is my go-to whenever I start having cravings. It fills me up and keeps me full longer, and it's a great muscle fuel. I always carry fruit and veggies with me to give me something to snack on between meals."

In addition to dance, Lopez relies on her trainers to keep her in great shape. In an interview with US Weekly (via Hollywood Life), the pop superstar revealed that she works out "three or four times a week" and mixes up her routines by exercising with two different trainers. "When I'm in New York, I work out with David Kirsch," she told the mag, adding: "He's an amazing trainer! When I'm in L.A., I work with Tracy Anderson. I like the balance that they both give me. They have two totally different approaches. I like switching it up with my body." With David, the superstar does planks, pushups and boxing while with Tracy, she freestyles it, but her routine often includes 3-pound arm weights and "butt and thigh moves that incorporate the core. We want to keep those famous curves."

Lopez may adhere to a strict workout schedule and perhaps and even stricter diet, but everyone deserves the occasional cheat day and, as she told People, she isn't immune to the odd sugary or salty treat. "We're all human," she declared. "I don't think you should beat yourself up if you make a mistake or if you have a potato chip. Everyone wants a cookie or a piece of cake or fried chicken every once in a while. It's not about that. It's about consistently and always trying to be better and trying to do good."

"I'm rarely in the sun" Lopez told US Weekly (via Hollywood Life), sharing one of her biggest (and simplest) beauty secrets. "I've never been one to take a lot of sun, which is why my skin has maintained itself." And when she does step out to catch some rays, "I wear a lot of sunscreen."

For years, Lopez has been working out with celebrity fitness guru Tracy Anderson and following her custom Tracy Anderson Method, which, "unlike other exercise programs that target the major muscle groups, focuses instead on the accessory muscles." On her website, Anderson says, "The routines change every 10 days — whether you're doing the workout in a studio, or in front of your own TV, ensuring that your accessory muscles never get bored."

And it clearly seems to be working for Lopez. The superstar follows her personal trainer's unique routine devoutly — Anderson has shared her client's full-body workout in Health and Lopez has even proudly declared, "[I'm like] a fighter, going into the ring. I do my cardio and I do my workouts with the Tracy Anderson Method."

From keeping dark circles at bay, to boosting energy, to helping maintain a healthy weight, sleep goes a long way in the health department. This is a fact Lopez knows all too well, as she has repeatedly preached the importance of sleep. "I love a good nine or 10 hours, but I can never get that," she admitted to US Weekly (via Hollywood Life), but "seven or eight is mandatory. [If I don't get it] I just don't feel right. I start feeling crazy, I get emotional and I feel tired all the time."

Speaking with ET, the mom of two echoed the same sentiment, saying: "Mommies have to be good for the babies at all times. They need to know that you're solid and strong and good. Sleep is very important. I get my seven to eight hours sleep no matter what."

Jennifer Lopez is a talented entertainer, proud mother of two and, as we've learned, a true source of health and fitness inspiration. Whether it be her unwavering positive mindset, her devotion to the Tracy Anderson method or impressive self-control (bye bye, caffeine!), Lopez's tips for staying fit and keeping an amazing physique, no matter her age, are really motivational... and can be applied to any lifestyle. Perhaps when she's not busy being amazing, she could give us all a few more pointers in an online J.Lo Bootcamp class?
