The yoga bolster supports the yogi's body in deep relaxation, allowing the muscles to passively relax; and in seated or reclining postures, it eases the strain and allows the yogi to go deeper in the pose. A bolster can also be used to support the spine and promote lung expansion during pranayama.
Here are a few examples of how yoga bolsters can be used in various asanas:
- In savasana (corpse pose), the bolster is placed under the knees to ease lower back strain.
- In balasana (child's pose), the bolster is placed between the legs so that when the body folds forward, it rests on the bolster.
- In viparita karani (legs-up-the-wall pose), the bolster is placed under the hips, making the pose more restful.
