What to do if i'm 5'4. weigh 56 kg..i want to shrink my waist..any exercise?

Spot fat loss does: not occur naturally. By losing weight in general some may be abdominal fat. But, we don't get to choose what area of body fat is lost from. Eat healthy & be physically active. Calories burned must > those consumed. Engage in regular aerobic exercise (i.e. running, swimming, Nordic track, bicycling, kickboxing, walking, cross country skiing, hiking, etc.)
