I really like Krista's page on women's weight training, an often overlooked topic. It's a fairly cohesive starting point for women who want to get into lifting weights. Her site has some sample workouts, diet info, injury resources, and a pictorial guide to lifting.
Strength training is an essential part of "training for the apocalypse". To be strong is to be capable in a variety of tasks like wrestling lions, saving someone from a burning building, or repopulating a dying society.
