Women bodybuilders do not typically build muscle as quickly or significantly as men; but with frequent high-volume weight training, they can still see enormous muscular developments. Bodybuilding requires workouts that feature a higher number of exercises, sets and repetitions, which overload the muscle fibers. This overloading stimulates the muscle-building process. Women just starting out should begin at the lower end of the high-volume workouts and increase their load as they develop.
It took FOREVER for me to find a workout plan that wasn't aimed towards wussy girls ("women should just focus on toning because actual strength training builds bulky muscle, which looks really bad in the kitchen" *eyeroll*) or towards experienced male body builders.
