No matter how many hours of cardio you do per week, sprints and long-distance running aren’t going to give you a bigger butt. The gluteus is a muscle. Just like any other muscle, it requires training to become tougher, tighter, and rounder. This means weight lifting!

Although many women avoid weightlifting for fear of bulking up, the truth is that everyone benefits from strength training. Weights build muscle. Building muscle helps you look long and lean, and the more muscle you have, the harder your metabolism works. This means that building muscle raises the number of calories you burn at rest.
