Lean forward and place the hands (straight) on the knees. Expand the anal sphincter muscles and simultaneously perform uddiyana bandha/abdominal lock(exhale all the air through the mouth,simultaneously suck the abdominal inside) and nauli in such a way that water is drawn up into the bowels.
Hold the water in the bowels for some time and then expel it through the anus.
