Pink Shares Bathing Suit Photo Wishing "Happy Birthday" to Carey Hart

Pink is celebrating her husband's birthday – in her bathing suit. The singer paid tribute to her motocross hubby in one of her latest social media posts with a black and white swimsuit snap of the two of them. "@hartluck we have celebrated 21 birthdays together, in some strange places, too. I've watched you grow from a young, gorgeous, insane athlete into a wise, even more gorgeous businessman, entrepreneur, father and husband. You are just getting started and I've loved growing up with you and raising little humans together. I am excited for you for this year ahead, maybe more than ever before. I wish you peace and love. I am so glad you were born. Happy birthday Carebear," she captioned the Instagram post. How does she stay so fit? Read on to see 5 ways Pink stays in shape and the photos that prove they work.

Pink prioritizes her mental health. One of her ways is by spending time outdoors. "In my career, I'm around so many people with so much energy directed at me," she says, "and I also make noise for a living. So it's important for my mental health to unplug and be in nature," she recently told Women's Health.

"I like being strong," Pink said. She exercises three times a day when she is on tour, once in the morning, once in the afternoon. She adds that her performances are "two hours of pure, psychotic cardio at night" onstage. "I have so much energy," she told Women's Health.

Pink trains with Jeanette Jenkins. The two do cardio HIIT, strength training with bodyweight and dumbbells, yoga, Pilates, cardio kickboxing, cardio sculpting with medium and light weights, and core-specific routines, she revealed to Women's Health. "I could pick up a car if I needed to," she said, revealing that she is the strongest she has been in her life.

Pink is one of the many Peloton devotees. She explains that "Cody Rigsby tells me to get my life together, and I listen," she said. 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.

Pink recently spent two weeks at SHA Wellness Clinic in Alicante, Spain. "It was the longest I've ever been away from my kids, and the biggest gift I've ever given myself," she says. "I did it for me, which in turn would be for them." She added: "I got rest. I wasn't getting rest before. I slept in a bed by myself for the first time in 11 years. I had time to meditate and cry and journal." During the two weeks, she was introduced to the anti-inflammatory Kushi diet, which involves eating a lot of vegetables, beans, and whole grains. She would drink apple cider vinegar mixed with water before every meal and didn't drink while eating. She still follows a lot of the principles at home. What does she eat? She has miso soup for breakfast. She snacks on string cheese and Pirate's Booty. Fish, salads, and scrambled eggs with spinach are other of her go-to's.
