i have seen the rising up done by both men AND women, and take great offense in the phrasing of your response.
in response to feivels question, it is done AFTER you finish and before the chazara begins. those who rise up three times do so upon completion of the silent shmona esrei, after they take three steps forward.
like i said before, i was taught that you remain in your spot STANDING until kedusha. then you take three steps forward, and when you say kadosh kadosh kadosh you rise up.
