In a recent study at Pittsburgh’s University of Pennsylvania, just practicing 20 minutes of yoga daily helped women cut even chronic pain by 60 percent in eight weeks. Yoga’s gentle stretches speed healing by boosting the flow of nutrient-rich blood to tissues, plus they prod your brain to produce painkilling endorphins, the study authors say. And you don’t need to schlep out to classes every week, either. You can take online lessons at sites like yogadownload.com and myyogaonline.com or download Deepak Chopra’s Authentic Yoga -- an app available for the iPhone, iPad and iPod at itunes.apple.com. You can also borrow yoga DVDs from your local library (dozens of newbie options are available, including Basic Yoga Workout for Dummies and Yoga for Beginners).
