Yoga Journal 21-Day Yoga Challenge, Day 7: Hip Openers with Rebecca Urban (VIDEO)

Hip opening asanas help make you feel limber and strong. This series works to get muscles pliant and blood flow moving at the center of the body.

When our partner Yoga Journal put out the call for their 21-Day Yoga Challenge, we knew we wanted to be a part of it. Over the course of three weeks, we're going to learn to incorporate a daily practice of breathing, meditation and vegetarian eating to our busy lives. We're hoping to emerge stronger, more flexible and mindful of the choices we make for our bodies.
