Reclining Hand-to-Big-Toe Pose is considered to be a supine yoga pose which is known to greatly improve your level of flexibility. Practicing this may give you an improved digestion, strengthened knees, and stretched thighs, hips, hamstrings, calves, and groins.
This is also good for relieving sciatica, backache, and menstrual discomfort, as well as therapeutic for flat feet, and high blood pressure.
