Many fans maintain that Kyle is in the best shape of her life at 54. In a recent interview with The Feast, per Bravo, she maintained she was amping up her commitment to fitness. She revealed that she was working out every single day of the week but Sunday.

2. She Has Workout Buddies

Kyle keeps herself accountable by enlisting workout buddies. She recently shared a photo of herself and a group of pals, including Teddi Mellencamp, at a workout class. “The girls… we all have different goals, different dreams, but the one thing we have in common is that we want to see each other succeed. That’s friendship but it’s also accountability. Because there’s always going to be a time where you want to give up, want to make excuses, want to quit. But accountability won’t let you. Accountability also means posting this pic despite so many things. Which one of us are you: the one taking the pic, the one who’s like ‘why are we taking a pic?’, the one who’s always finding her angle, or the one who’s showing off her tree pose?” she captioned the snap

3. She Bikes

Kyle loves cycling. “Went mountain bike riding through one of the most beautiful places I have ever seen,” she captioned this photo. She also loves SoulCycle classes and riding her Peloton. The Cleveland Clinic explains that biking, a low-impact aerobic exercise, is great for building muscle, improving strength and flexibility, and improving balance. It can also boost mental health and help other health conditions, including arthritis.

4. She Hikes

Kyle also loves hitting the trails. "I love hiking, going on walks with my friends on steep hills, inclines. I just like to be outdoors mainly," she told E! News. “Hiking is one of the best ways to get exercise. No matter what type of trail you find yourself on, hiking is a great whole-body workout—from head to toe and everything in between,” says the National Parks Service. Some of the physical benefits include building stronger muscles and bones, improving your sense of balance, improving your heart health, and decreasing the risk of certain respiratory problems. It also offers many mental health benefits, according to a Stanford University study.

5. She Uses Exercise to Treat Stress

Kyle loves the mental health benefits of exercise. "The links between depression, anxiety and exercise aren't entirely clear — but working out and other forms of physical activity can definitely ease symptoms of depression or anxiety and make you feel better. Exercise may also help keep depression and anxiety from coming back once you're feeling better," says the Mayo Clinic. “For me, if I want to feel good and, you know, if I’m stressed, it’s exercise, exercise, exercise,” Kyle told US Weekly.
