That's just your body shape. You can't control your body's fat distribution. Just keep doing what you're doing and eventually the lower-body weight will come down to match your normal waist:hip ratio.

The key to successful weight loss is to have a healthy diet, NOT crash diets or blah diets, and stick to an exercise you like. For example, if you exercise on a treadmill and you hate using the treadmill, you're likely to stop using it after a few days. Personally, I like the elliptical better than the treadmill because it's more efficient and doesn't hurt your feet, and swimming is an excellent exercise as well.

just cardio and healthy diet. how do you make your waist smaller? can you comment and help me
