So you want a fuller, stronger butt.
As BuzzFeed Health has previously reported, your butt is made up of three glute muscles — the gluteus medius, gluteus minimus, and gluteus maximus — which are covered with a layer of fat. So getting that bun definition is going to require way more than just doing an absurd amount of squats, or trying to eat slightly more carefully. It actually usually requires following a careful diet that's focused on losing or maintaining body fat and a workout routine that challenges the entire body, especially the glutes.
Building a larger tush is a commitment, so to make it a little more doable, here are some cheat sheets to help you with butt-particular diet and exercise.
