Recommendations for female trainers/fitness models to research that don't 'sell out' to gimmicks?

I don't believe for one second 'Mel B' got her amazing body and shredded abs by 'the Jenny Craig Diet' or Jennifer Nicole Lee from her latest promotion for the 'ab circle.' I enjoy free weight training and love circuit training, (let's face it nobody gets the fitness model body by doing high levls of cardio/machines anyhoo). I realise there is big money to be made with celebrity endorsements, but I do lose respect for people that go against all their beliefs just to earn a quick buck or two! I was just wondering if anybody could recommend any women trainers/atheletes that I can research and aspire to. Or, even better, if you are a fitness enthusiast yourself, or a figure model yourself, can be your prodigy?

I'm looking for quick tips and advice and to see someone that has made the transition themselves. I know a lot of male trainers; my boyfriend being a personal trainer himself, it's brilliant! I would just love to meet or hear about a female I can relate to. Any ideas?
