Ask a typical woman if she would like more strength and lean muscle (you have to say lean because if you just say muscle it will automatically be equated with giant, hairy, testosterone, steroid-driven bodybuilding bulky muscles). She will say "sure". Now say that doing so will make her 20lb heavier. It doesn't matter if it's lean body mass, it will still strike fear because the scale will now read higher.
Let's do a hypothetical. Suppose you have two twin women, they are identical in every way. They both have an average body composition. They decide to improve how they look. One decides to eat a lot less, do a lot of cardio, sit-ups, light weights, etc, i.e. do what the majority of women do. The other decides to lift heavy and eat better, i.e. do "man" exercises, and eat normally but with healthier food, such as the diet advocated here. Give them both a year. Who will look better? Who will be healthier and perform better? Who will have a lifestyle that is indefinitely sustainable? Which would you rather be?
