Kate uses WW to stay accountable. "My struggle is not in weight loss," she told the Today Show. "Mine is about staying healthy, trying to stay focused and balanced." She also added: "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. … Everyone's looking to how do you get motivated, how do you stay motivated?"

Kate takes supplements from her INBLOOM line, which she founded on the belief that beauty starts from the inside out. "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 makes fitness a priority. "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 told 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 maintains variety with 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's focus when working out is feeling good. "I've always felt that wellness is about your quality of life," she explained to 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 is a longtime yogi like her mother, Goldie Hawn. "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."
