Downward Facing Dog (Sanskrit: Adho Mukha Svanasana) may very well be the most well-known yoga pose of them all.
Both a stimulating and relaxing posture, Downward Dog stretches and strengthens the entire body. The pose is most commonly performed during Sun Salutations and in a vinyasa practice.
The pose itself strengthens the wrists and shoulders while stretching the chest, spine, hamstrings, and calves. Once strength has been developed to hold it, it becomes more of a resting pose than one which requires more effort, as it is very calming for the mind.
