You might be thinking that doing 1000 sit-ups or running miles upon miles are the answers to removing the pesky layer of fat on your waist, but you'd be sorely mistaken. Instead of trying to target specific unflattering body parts, focus on building muscle all over your body through a variety of sports and exercise. The more muscle you have, the more calories you burn, and actually the biggest fat-burners are found on your lower body (glutes, hamstrings, quads, etc.). If you ever wondered why they say "don't skip leg day," there's your answer. Plus, you should know that many exercises that aren't directly associated with your hips and abs do still engage them in a significant way.
