Horse pose is part of the intermediate series of Ashtanga yoga. According to the teachings of Iyengar yoga, it improves the blood's circulation through the hips and can fix small distortions in the thighs and hips. It also strengthens the core, hip, ankle and knee joints, as well as the leg muscles.
This pose is sometimes practiced with the hands placed in a simple namaskar mudra (salutation seal) position in front of the chest rather than wrapping the arms around each other.
Horse pose is an intermediate pose that should not be practiced by beginners without the assistance of a yoga instructor.
