Maya is from the Xbox (and PS2 and PC) title Yourself! Fitness, an interactive personalized fitness program. She's definitely attractive, but not buxom, wears regular workout clothing instead of a chainmail bikini, and functions as a virtual personal trainer. She encourages, cajoles, reprimands (if you miss appointments with her) and assists people with a variety of routines. She's been described by reviewers as amazingly realistic, very well animated including segues between movements.
See her in motion, if you like:

Just thought this might be interesting to some of the avatars in here. Sorry to disappoint any girls who were hoping for the nomination.
