Kate promotes taking supplements and even 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 told InStyle. "My answer was always, 'I know this is boring, but it's an inside out job.'" "Nutritional supplements are meant to complement a healthy diet, not replace it," says the Mayo Clinic. "In certain cases, however, fortified foods and dietary supplements may be useful in providing one or more nutrients. For example, women who are pregnant or hoping to conceive are advised to take prenatal vitamins that contain folic acid. You also may want to consider a nutritional supplement if you don't eat enough healthy foods or don't eat a healthy variety of foods — especially if you have an underlying medical condition."

"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, formerly Weight Watchers. "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."

For Kate, exercise is a daily job. "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 mixes up her workouts. "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."

Kate breaks a sweat for her body as much as her mind. "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."df44d9eab23ea271ddde7545ae2c09ec

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." "Research suggests that yoga may," says the NIH:

• "Help improve general wellness by relieving stress, supporting good health habits, and improving mental/emotional health, sleep, and balance.
• Relieve low-back pain and neck pain, and possibly pain from tension-type headaches and knee osteoarthritis.
• Help people who are overweight or obese lose weight." And more.

Kate who swears by intermittent fasting. In an interview with Women's Health she revealed that timing her eating helps improve her energy. "It's not for everyone," she admitted. During the mornings when she is fasting she will consume just celery juice, coffee, or tea, waiting until 11 or 11:30 a.m. to start solid food. "If we fast for a while, there are certain processes in the body that can relieve inflammation, and it may have other benefits," says Dr. Donald Hensrud, director of the Mayo Clinic Healthy Living Program, said to the Mayo Clinic. However, "It's a slippery slope. I've actually seen malnutrition in people who have taken caloric restrictions too far because they're trying to live longer. Yet it causes malnutrition, which is counterproductive," Dr. Hensrud said.

"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."

Kate confessed to Well + Good that she is "an ab [workout] fanatic," adding "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 is a big fan of the workout buddy system. "Find a friend that likes to get it and GET IT!" she captioned a recent workout snap with pal Sophie Lopez. "Look for someone with the same goals, schedule, and commitment you have. Someone who makes you feel positive and inspires you to hit the trail or treadmill on a regular basis," says the CDC. "How do you find the right fit? Talk to friends, co-workers, neighbors, people at the gym. Or find a buddy closer to home: What about a hike with your dog, who thinks every walk is the best walk ever? Now quality time is also fitness time. Good move!"
