Take a walk through the gym someday and you'll probably find mostly men on the bench press machines.
Many men place greater emphasis on doing chest exercises at the expense of other muscle groups.
Women, on the other hand, tend to avoid increasing their chest muscles because they fear looking like a gladiator. So some women started pumping up their chests in hopes of increasing their breasts. Chest exercises don't increase breast size either, but these exercises do help keep breasts firm. This information doesn't mean you shouldn't work out your chest muscles if you're female. A muscularly balanced body is the key for everyone, so put an exercise program together that incorporates all of your major muscles.
