Kate Hudson is starting off the new year by sharing some of her greatest hits.

How does the 42-year-old keep herself so fit? Read on for 10 of Kate Hudson's top tips for staying in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

Accountability is one of Kate's keys to getting into and staying in shape. "My struggle is not in weight loss," she told the Today Show. "Mine is about staying healthy, trying to stay focused and balanced." This is why she opted to partner with WW. "One of the things about this re-imagining of WW is it's not just about weight, it's about wellness. To me, it's all about support."

Kate is such a big proponent of taking supplements, that she started her own line, INBLOOM. "Really where it started for me was beauty. Magazines would always ask me, you know, 'What are your favorite beauty products? What do you do to keep your skin looking rested?'" she explained to InStyle. "My answer was always, 'I know this is boring, but it's an inside out job.'"

Kate tries to work out almost every day. "Now that Rani is getting a little bit older and her nap schedule is longer, I've been able to work out at least 30 minutes a day, maybe five times a week," she revealed to InStyle. "I make sure that I don't go a day without doing something for 30 minutes. I've been doing that since April and I've noticed enormous changes in my body."

Kate doesn't rely on just one workout to stay in shape. "I do everything. I have to switch it up, I get so bored," she told InStyle. "I've been loving the Obé app, they have 20-minute workouts that are really hard and if you do them with the proper form they're really effective. I love my yoga apps, like Glo, and I use Body by Simone and Tracy Anderson's apps too — there's nothing better than her abs workout. I love my Peloton. I love Pilates — that's always been my number one."

Don't just focus on the physical benefits of exercise, but the mental as well. "I've always felt that wellness is about your quality of life," Kate told Women's Health. "You need to know what makes you feel good. It's about doing the things you love, eating the things you want to, exercising and not feeling like you need to [push yourself] for two hours in a hot room. You can just take a nice walk and still be healthy."

Kate loves striking a pose….a yoga pose that is. "It's about understanding your own individual likes, not fads," she revealed to SELF. "Anything you do helps. You could sit there and not think of your mantra for your whole practice, but you're still benefiting."

Kate is one of the many stars who swears by intermittent fasting. She told Women's Health that timing her eating helps improve her energy. "It's not for everyone," she admitted. During her fasting period she drinks just celery juice, coffee, or tea, waiting until 11 or 11:30 a.m. to start solid food. 

Kate is also a big proponent of meditation. "When I [meditate], I can feel the difference right away. I feel myself becoming calmer, more centered and clearer-headed," she wrote in a blog on her Fabletics website. "Meditation also made me realize that there are times when I thought I had a grasp on what was going on with myself internally, then I meditated and found that my body was telling me something different."

If you want flat abs a la Kate, you need to work for them. "I'm an ab [workout] fanatic," Kate told Well + Good, "and I hate [doing] them." Stability ball crunches help keep her midsection tight. "I've had a C-section, and I think any woman who has had a C-section knows how hard it is to re-engage that lower part of your abs," she said. "My C-section was 16 years ago, but if I go a few days without doing abs, my brain has a hard time re-engaging that area."

Kate suggests finding a workout buddy. "Find a friend that likes to get it and GET IT!" she captioned a recent workout snap with pal Sophie Lopez.
