I have been running cross country for four years. I have a decent bf % at 12. I have a decent diet, and run 4-5 miles a day. I also swim competitively every year. yet I've always had a problem with making my midsection less fat. I work my core and try so hard but never any change I don't know if I'm the most unlucky person on the planet or I'm doing something wrong.
