Others mentioned some ace advice here. It's such a HUGE misconception that you'll "hullk-like" from lifting.
The only people that you see like that have the aid hormones (which often have nasty side-effects, in most cases, there are exceptions for those that use it as therapy for health conditions). Women who use said hormones are easy to spot as they get very masculine-like features along with such muscle-mass.
MORE people should lift weights -- ESPECIALLY women. Women's bone density rapidly begins to deteriorate within their early 30's. Things like pregnancy and menopause are especially unforgiving to the bones. For men, I believe it is about the 40's mark. Thus, lifting weights = decreasing the possibility of early onset of osteoporosis. In addition, women who are scared to lift because they think they will get monstrously big are also gravely mistaken. Although women produce testosterone, they don't produce nearly as much as men. If anything, women will tone, get leaner, and look younger for it.
Another perk of having more muscle mass is that your body will burn more calories, even while the body is at rest (as opposed to only doing cardio - you will only burn as much as you expend in that duration, to put it simply). This is good news for food-lovers, as you will need to eat more (of the good stuff - not junk food/crap) to build and maintain muscle.
Working out is a great outlet. You'll reduce stress, increase longevity, build a stronger immunity, etc. And, you'll get the benefits of looking awesome in the long run (coupled with a structured eating lifestyle, of course), which will in turn, boost your self-esteem
Anyone who says working out will make you look "disgusting" needs a reality check.
In contrast, it is wise to thoroughly research how long you should be exercising, how many "weight"days and "cardio" days you should have in your exercise regime, have adequate nutrition (macro-nutrient intake) to match your expenditure etc. Balance is key. Rest and recovery is important. Otherwise you will do more harm than good to your body.
