Is it possible to target specific parts of your body weight trying to lose weight?

No: You really have no control over where on your body you will lose weight. Hitting targeted areas, such as the abs with crunches, helps build muscle and lean out, but it doesn't result in weight loss just in the mid-section. To target specific areas of fat like the love handles requires something like liposuction. Some seem to lose more in certain areas quicker, but this is more genetics.
