Hips are a notoriously difficult place to lose weight and many people tend to put on fat in this region. If you are among the unlucky few then you need to go on a diet and lose weight in the rest of your body and this will help you lose weight in the hips. Stomach crunches and sit ups can help you shape your hip, but this can be done only after you lose all the fat. Running on the beach is a good way to lose weight, especially around the stomach and hips. Hope it helps, Good Luck
