CNN  — 

Celebs may look nearly perfect in their Instagram feeds, but on closer inspection, their looks aren’t only due to loads of money and great genetics. We’ve rounded up advice from over a dozen celebs who frequently share their fitness and nutrition routines on social media. The overarching theme? They work hard for those A-list bodies. They also stress health, wellness and — hooray! — self-care. From superhero-playing actors to busy moms who put women half their age to shame, here’s a little motivation to make health a priority in the new year.

Serena Williams

Serena Williams is considered by many to be the greatest female tennis player of all time, and was even named the AP Female Athlete of the Decade. She recently won the ASB Classic in Auckland, New Zealand, her first title since giving birth to her daughter three years ago. “It feels good,” Williams told CNN. “It’s been a long time. I’ve been waiting two years for this moment. I think you could see the relief on my face.”

She also spoke about the importance of staying positive. “You have to be your biggest cheerleader, especially if you’re feeling you’re not doing everything right — or even if you are doing everything right but things aren’t working out for you,” she added. Recently, Williams even tried out a little boxing with Mike Tyson to mix things up, and she’s recommending her favorite health and fitness gear for 2020 in her Amazon store.

Jennifer Lopez

Turning 50 in 2019 did nothing to slow JLo down. Not only did she bare nearly all as a stripper in “Hustlers,” and wow fans when she strutted down the Versace runway in the same dress she made famous 20 years ago, but she and fiance Alex Rodriguez started a viral fitness trend with their 10-day no-sugar, no-carbs challenge. Lopez told Ellen Degeneres that even though she works out a lot, her trainer suggested going carb- and sugar-free for 10 days to move the needle for her “Hustlers” role. “He’s like, ‘Let’s just cut it out.’ I was like, ‘Completely? Like cold turkey?’ And he’s like, yes,” she told the talk show host. “Ten days. It was really hard.” But, she added, it worked.

Chris Pratt

When you play a superhero, you need a superhero physique, and Pratt’s open about sharing the fitness routines that got him there with us mere mortals. “I like to mix it up…I’ll lift weights. I do cardio, I’ll do some yoga. I like to box…I’m always trying different things out,” he says on Amazon, where he has a store featuring some of his favorite workout gear. “Being active is more than just about getting fit -— the mental and emotional benefits go far beyond the physical. It’s about setting a goal and showing up for yourself.” From CrossFit, to walking on a steep incline on the treadmill, to drinking lots of water, to medicine ball workouts, he’s full of wellness motivations.

The pop star, who frequently shares videos of her fitness routines on Instagram, let fans in on her workout plans for 2020 with a recent video of her going through yoga moves. “In 2020 I will be doing a lot more acro yoga and the basics for yoga,” she wrote. To move like Spears, change things up with a mix of activities — from barre classes to weightlifting to yoga. Studies have shown that changing up your workout routine can improve your body’s response to exercise.

Kumail Nanjiani

Fans of Nanjiani who know him from “Silicon Valley” and “The Big Sick” were stunned when the comedian posted a couple of “thirsty shirtless” pics on Instagram last month. “I found out a year ago I was going to be in Marvel’s Eternals and decided I wanted to transform how I looked,” he wrote. “I would not have been able to do this if I didn’t have a full year with the best trainers and nutritionists paid for by the biggest studio in the world.” One of those trainers, Grant Roberts, told The Hollywood Reporter that Nanjiani’s intense training sessions averaged four to five times a week.

Halle Berry

Just take a peek at the Oscar-winner’s regular #FitnessFriday pics, and it’s clear wellness is a top priority for Berry. Her training for the upcoming mixed martial arts movie “Bruised” has Berry doing lots of MMA moves, and, she writes, she’s especially drawn to Muay Thai. “Prepare to burn anywhere between 800-1000 calories per hour – but don’t worry, you can do it! It’s a great way to learn to self-defense and use every part of your body in your workout (including your knees and elbows)!” Berry also subscribes to a keto diet, eschewing sugar and carbs.

(A full-on keto plan isn’t for everyone, though: Talk to a health care provider if you’re thinking about making changes to your diet.)

Zac Efron

When killer abs are part of your job (hello, “Baywatch”), fitness has to be part of your daily routine. Efron often shares gym — and shirtless — photos on social media, but getting that six-pack is no easy task. His trainer, Patrick Murphy, shared the “Baywatch” workout with Men’s Health. It includes supersets of exercises such as kettle squats and box jumps or banded reverse flys and explosive Bosu pushups, along with two-a-day workouts and a nearly carb-free diet. Also on the docket: self-care. The actor recently posted a shot of himself in his home sauna.

Paltrow’s Goop brand is all about wellness, so it’s no surprise the Oscar-winning actress shares frequent workout pics with her fans. Tops on her list: exercising with business partner and trainer Tracy Anderson, whose method includes dance-inspired aerobics and small muscle group toning. Paltrow also points to drinking alkaline water (it’s said to keep the body’s pH levels balanced), and has partnered with Flow Alkaline Spring Water. Added to her daily workouts and hydration? A mostly clean diet, a once-a-year cleanse and really great genetics.

A longtime fan of high-intensity training, he’s back at it following a car accident. “I want to inspire & motivate people to challenge themselves to be great,” he recently wrote. “We all have greatness within…it’s up to us to tap into it.” He’s also an avid runner who has led thousands of fellow pavement pounders on 5K runs.

Khloe Kardashian

The “Revenge Body” host is a dedicated fitness fan who likes to switch things up in her workouts, which include a mix of cardio (including boxing), circuit training and weightlifting. She recently told the podcast “On Purpose with Jay Shetty” that her workouts are more about health than weight loss. “It was never: ‘I want to look good in a bikini.’ It was never my goal,” she told Shetty. “I just wanted to feel good mentally. And, I think when you start putting yourself first, you start feeling so much better.”

Kate Hudson

She acts, she sings, she runs a fitness-wear company (and a recently-launched an eco-friendly fashion line), she has three kids. She skis. She lifts. She runs. She does Pilates. What doesn’t Kate Hudson do? A spokeswoman for Weight Watchers, she’s sharing her nutrition trends on Instagram in the new year and points to choosing nutritious options like grilled salmon with mango salsa, sauteed squash and celery juice. And Hudson seems to be following a healthy plan: “I’ve done it without stressing on food or working out like crazy although I have been disciplined,” she wrote on Instagram.

She also shares what she eats in a day, including an effort to eat more plant-based meals (spoiler: a day involves lots of clean choices like cauliflower rice, avocado and protein ball bites). To maintain her healthy eating routine, Sims writes on her blog that she meal preps. “I prepare two proteins, two salads, two veggies/grains and then one one-pot dish like a casserole something in a crock pot,” she writes. “I store all of the food that I prep in glass containers so it stays fresh throughout the week.”

Deontay Wilder

Heavyweight WBC boxing champ Deontay Wilder packs one of the scariest punches of all time. With a record of 42-0-1 with 41 knockouts, he’s a feared force in the boxing world. To stay on top of his game, Wilder, nicknamed the “Bronze Bomber,” uses nontraditional methods of working out. “I stay away from road running because it tears up your knees over time,” he said in an interview with The Washington Post. Instead, he works out in the water to reduce the stress on his body. “I love the water because it builds all your muscles in your body. After I get finished with a water workout … I can’t even tell you the name of the muscles, that’s for sure, but I feel it.” His love of water extends to scuba diving too, which you’ll see next to the weigh-in pictures and knockout highlights on his Instagram feed.
