You can't. Genetics. Not only do ur parents genes effect the width of ur hips, they also effect where u store fat, and if thats not over the top of ur glutes (butt) then theres not a whole lot you can do. sorry about that. Source(s): Diploma in Anatomy and Fitness
Best Answer - Chosen by Voters WOW..that person with a "diploma" is very wrong.There is something you can do but it takes time and work.To get a bigger butt you need to eat right..many small meals a day.Eating junk/fatty foods will not work..you need lots of protein to build muscle.Squats and Lunges are the best for getting a bigger butt. There are so many other excercises also( I don't know them all!) ..just use google and type in excercises for a bigger butt/hips. Good Luck!

Just google your question, Youtube is also great for videos on how to get a bigger butt/hips as well.
