10 All-Natural Ways to Stay Young

6. Do yoga

More energy, better posture, greater flexibility, improved mood, and less stress are just some of the rewards of this mind-body workout. "Yoga means 'union' in Sanskrit," says Cyndi Lee, founder of New York City's Om Yoga and a FITNESS advisory board member. "Through conscious yoga breathing, you become aware of the connection between mind and body." That translates into major anti-aging advantages. Yogic breathing has been shown to oxygenate the cells, ridding them of toxins, helping prevent illness, and making skin radiant. Unlike other exercises, says Lee, yoga poses are designed to work the inside of your body as well as the outside, which helps rejuvenate the digestive system, the reproductive system, even the immune system. "Yoga is like wringing your body out like a washcloth," she says. "It's one of the best ways to keep things moving."

Try it! Practice yoga or other mind-body activities at least twice a week, says Lee, to give yourself an energy boost, help build bone mass, and de-stress.
