Once ridiculed as a new-age trend, yoga has gone mainstream. From CEOs to soccer moms, everyone seems to be jumping on their yoga mats, either for its gentle philosophy or health benefits. There are proven perks to picking up the practice. If you’re a stress mess, doing yoga releases oxytocin, a hormone associated with feelings of relaxation. It can also improve chronic conditions like asthma, back pain, arthritis and insomnia. Other studies show a link between yoga and a reduction in heart disease risk. No matter what form you choose, yoga can help improve posture, breathing, strength and flexibility. Even if you’re a newbie who hasn’t touched her toes in years, you can find a yoga style that’s right for you. Check out this primer to help you figure out what type of yoga is the best fit for you.
