No guy who has a gym membership wants or sticks with a female trainer. Even the guys who aren't interested in bodybuilding still prefer a male trainer for this main reason. While female trainers may have studied anatomy and know fitness, male trainers know better how to train men on how to achieve their goals. And the same goes with the women and female trainers. Not to mention the whole opposite sex angle. If a man is being trained my a hot woman, his mind will probably be focused elsewhere, especially if she dresses in tight workout clothes. And what woman isn't going to check out a ripped male trainer who may be more cut than her man.
