How can you tone your tummy and lose love handles without losing weight anywhere else?

You can't target fat loss to a certain part of your body. Yes you can focus more on a certain part, like doing crunches and other ab workouts to focus on your belly region, which will strengthen your core muscles and help you lose fat faster. But, if you're losing fat from that area, then you're losing fat from other areas of your body as well. If you have unwanted fats in your body, try losing it and build muscles instead.
