I am constantly asked "Do I need to lift weights (in addition to monitoring my diet) to lose weight?" The answer is no, other forms of exercise can achieve that goal, but the most efficient way to lose weight is to lift weights! Yes, cardio will burn calories, but weight lifting will do the same, plus it will boost your metabolism, potentially keep you burning calories for hours after your workout is done, and give you that more sculpted look--without looking bulky. The following article from the American Council on Exercise explains how weight lifting helps for weight loss and also provides a quick circuit for you to try when you are at home or the gym. Go for 20 minutes with little rest in between exercises and you are good to go!
