Kate Hudson in Workout Gear Duets With Her Brother

Kate Hudson is dueting with her brother, Oliver Hudson, in her workout clothes. In a new social media post, the makeup-free star shows off her amazing body in an exercise top while singing acapella with her bro. "Chopped My Salad 🥗 #siblingremix," she captioned the Instagram post. How does the star approach diet, fitness, and self-care at 45? Here is everything you need to know about her lifestyle habits. 

Hudson maintains that "tuning in" to her body was a game changer. "If you're tuned in and your body tells you, it really does speak to you," she told Today. "One day, I tuned in and I was like … I don't feel strong, I feel long and I love my Pilates but as I get older… am I doing enough (strength) exercises?" According to clinical trials, consuming more protein than the recommended dietary allowance not only reduces body weight (BW), but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets.

Kate recently discussed how she has changed up her approach to fitness in her 40s. She is now working out with Brian Nguyen, who has her lifting weight. "When (Brian and I) started working together, one of the things I never did was strength training, that was something I never realized was a huge part missing," Hudson told Today. Some of their go-to exercises? Hip and glute bridges, planks, bodyweight squats, and lunges. According to the Mayo Clinic, strength and weight training help reduce body fat, preserve and increase lean muscle mass, and burn calories more efficiently. Strength training may also help you:

• Develop strong bones
• Manage your weight
• Enhance your quality of life
• Manage chronic conditions
• Sharpen your thinking skills

Hudson also shifted her approach to diet.  "Food is everything," she says. "The food we eat is fuel for our body," she added. "We, especially women, should really be eating more protein, especially in the morning."

Hudson uses MyFitnessPal to track food. "Food is 80% of the challenge … and tracking it, knowing it, understanding it, and having the knowledge is something I'm passionate about," she said. She revealed that while shooting Something Borrowed in 2011 she was on a raw food diet. "It was trendy at the time to eat raw, but I gained maybe 10 to 15 pounds and I didn't understand what was happening because I thought I was eating so healthy and I cut out meat," she said. "I started tracking, and (realized) I was eating about 3,000 calories of just nuts … If I didn't have access to understand (that), I would have never known," Hudson adds.

Kate emphasizes the importance of having support. "What's really important is to have access to support … we can't do it alone … I guess some people can but for most of us like myself, I need a support system," she explains.
