This balanced yoga sequence will work your glutes and outer hips to encourage greater lower-back stability. Expect sun salutations and classic Hatha poses, but with variations that focus on external rotation of the legs. You'll move through poses that strengthen the posterior chain and hip flexors, such as locust, a no-hands natarajasana, and one-legged bridge, then wind down with a couple hip stretches and a brief savasana.
