Rijker has been on the cover of numerous magazines including Inside Kung Fu. As a professional boxer, she has won the WIBF Welterweight Title, and has beaten name fighters such as Marcela Acuña (5th-round K.O.; Acuña was 0-1 going into the fight, and 19-4 as of June 2005), and Deborah "Sunshine" Fettkether (10th-round decision; Fettkether was 8-4-3 going in).
After winning her first 14 fights, but failing to secure a match with Martin, Rijker stepped away from boxing in 1999 to pursue a career in Hollywood. She co-starred as Billie 'The Blue Bear' in 2004's Oscar-winning, female boxer-based film Million Dollar Baby. She was also featured in the documentary film Shadow Boxers. She played a minor role in Rollerball (2002 film) and had a brief cameo in the season 2 finale of The L Word as Dana's trainer. She returned to The L Word in Season 5 as Dusty, Helena's cellmate in prison. Rijker also played a Romulan communications officer in the film Star Trek. Rijker also auditioned for the role of the female terminator in Terminator 3: Rise of the Machines and was one of three finalists.
Rijker stated that although not retired as a professional boxer, she would only consider one more fight - about with Laila Ali.
She remains busy giving lectures and seminars to athletes and people from all walks of life to perform their best, while still maintaining her top physical form and a strict diet.
