There are three bandhas which are considered our internal body locks, prescribed in the different asanas. The bandha is a sustained contraction of a group of muscles that assists the practitioner not only in retaining an asana but also in moving in and out of it. The Mūla Bandha, or root lock, is performed by tightening the muscles around the pelvic and perineum area. The Uḍḍīyāna Bandha, often described as bringing the navel to the base of the spine, is a contraction of the muscles of the lower abdominal area – this bandha is considered the most important bandha as it supports our breathing and encourages the development of strong core muscles. Jālaṅdhara Bandha, throat lock, is achieved by lowering the chin slightly while raising the sternum and the palate bringing the gaze to the tip of the nose.
