How can I lose weight but keep my booty?🍑

Im at 152lbs right now. And I can't stop looking each reflection I pass and just saying how fat I look. So Im deciding I want to loose 10lbs ( at least). Ive been working out( at home) for a year and see very little progress. My SO says I look good and he doesn't want me to lose any weight because he thinks I will lose my butt😒 But omg ink what else to do to get rid of my mommy tummy and flabby arms🐷
