Mula Bandha is a yoga practice that involves contracting the muscles of the pelvic floor. For men, it involves contracting the muscles just inside the perineum, while for women it focuses on contracting the cervix and vaginal muscles. The practice is done gradually by starting with a gentle contraction and gradually increasing the tension over 10 repetitions. Mula Bandha draws energy up from the base of the spine, intensifies awareness, and increases vitality by stimulating heat and flexibility in the pelvic region.
