Garland pose is a basic posture that works several different body parts simultaneously, opening the hips and improving mobility. It helps the practitioner increase their flexibility before moving on to more advanced postures. And as it does improve the posture in general, garland pose is especially recommended for people who spend a lot of time sitting down each day.
More advanced variations include putting the hands on the ground or grabbing onto the heels. Once the practitioner is comfortable in this pose and can perform it without straining the knees, it can also be used as a meditative posture.
