Yoga Journal 21-Day Challenge, Day 9: Standing Poses With Jason Crandell (VIDEO)

Today's practice deepens the strength and stability found in a series of standing poses, first introduced on Day Four.

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. You can check out our progress at Team HuffPost's Social Workout page and you can follow along on our blog. Want to join the challenge?
