The name Downward Facing Dog goes hand in hand with yoga, but just because you've heard of this pose
doesn't mean it's easy to do.
Beginners often lean too far forward in this posture, making it more like a plank. Instead, remember to keep your weight mostly in your legs and reach your hips high, with your heels stretching toward the floor (they do not need to touch the floor). Bend your knees a little to facilitate the move if you have tight hamstrings. Keep feet parallel.
