Kate Hudson in Two-Piece Workout Gear is "Absolutely Dreamy"

Kate Hudson is looking gorgeous in Greece – in her workout gear. In a new social media post the actress shows off her incredible body during a vacation workout session, wearing a leotard in her mirror selfie. “Absolutely dreamy!” she captioned a series of Instagram snaps taken at the One and Only in Athens, Greece. How does she approach diet, fitness, and self-care? Here is everything you need to know about her lifestyle habits.

1. Changing Her Approach to Fitness

Kate doesn’t train the same way at 45 that she did at 25. She works out with Brian Nguyen, who has her lifting weights. “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

2. Listening to Her Body

According to Kate, “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?”

3. Greater Emphasis Protein

Hudson also amped up her Protein intake. “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.” 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.

4. Keeping Track of Food

Hudson is a big fan of MyFitnessPal. “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 explains that even if you think you are eating healthy, like she did when she was on the raw food diet in 2011 while filming Something Borrowed, you might be gaining weight instead. "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.

5. Saunas

In one of her recent photos, Kate takes a dry sauna in her swimsuit. While some claim the health benefits of saunas are plentiful, including detoxification, increased metabolism, weight loss, increased blood circulation, pain reduction, antiaging, skin rejuvenation, improved cardiovascular function, improved immune function, improved sleep, stress management, and relaxation, there isn’t a lot of research backing up the claims.
