Yoga Sandbags are a great prop that aid the user in the process of strengthening and lengthening poses. They are easy to use, and they are definitely a welcome addition to the yoga props. They help you deepen your postures by adding weight, such as on the thighs in hero`s pose and reclined leg stretch. A sandbag on your abdomen brings awareness to the muscles involved in breathing. A sandbag can be used under the feet for a hamstring stretch or used under the buttocks for lift in seated poses.
