Canadian pole vaulter Alysha Newman had an all-time celebration after securing a bronze medal at the Olympics ... busting out a quick twerk in front of the entire stadium!!
The epic moment went down on Wednesday ... after the 30-year-old cleared the crossbar at 4.85 meters -- a new record for her country.
Newman initially faked an ailment after hopping off the mat ... before putting her hands on her knees and shakin' it for all to see.
