Downward-Facing Dog is a common yoga pose that resembles an inverted "V" shape. To perform this pose, start on your hands and knees, then lift your hips up and back, straightening your legs and arms. Your heels should ideally reach toward the floor, and your head should hang between your arms, creating a long line from your wrists to your hips. This pose stretches the hamstrings, calves, and spine, while also strengthening the arms and legs. It is often used as a transitional pose in yoga sequences, helping to improve overall flexibility and promote relaxation.
