With very few exceptions, the principles of diet & exercise are the same for men and women. And don’t worry about becoming a manly she-beast from lifting weights; most women can’t gain muscle at anywhere near the rate of men, no matter how hard they lift. Remember, female bodybuilders are lifting weights constantly, eating twice as much as you and taking male hormones. Getting huge doesn’t just happen to men, let alone women.

A word of warning: many female fitness magazines tend to be really idiotic and gimmicky, fixating on things like “spot reduction” that were disproved 50 years ago, and trying to sell whatever their advertisers are pushing that month. If the magazine shows a skinny bimbo doing curls with 5 lb dumbbells, you should probably throw it in the trash.
