Let’s be real for a second. If you scroll through Instagram or TikTok for more than five minutes, you’re bombarded with influencers claiming a specific "tea" or a three-minute workout gave them a shelf-like backside. It’s mostly nonsense. Genetics plays a massive role in where we store fat and how easily we build muscle, but that doesn't mean you're stuck with the hand you were dealt. Understanding how do you make your buttocks bigger requires moving past the fluff and looking at the actual physiological requirements of muscle growth.
Muscle doesn't just appear because you moved your legs. It’s an adaptive response. You have to give your body a reason to change.
Honestly, most people fail because they under-eat or they spend hours on a StairMaster thinking cardio is the answer. It isn't. If you want to change the physical dimensions of your glutes, you’re looking at a combination of mechanical tension, metabolic stress, and a caloric surplus. It's a slow process. It’s often frustrating. But it is entirely possible if you stop treating your body like a math equation and start treating it like a biological system that needs specific inputs.
The Anatomy of a Larger Backside
Your "butt" isn't just one muscle. It’s a complex group. You’ve got the gluteus maximus, which is the largest muscle in the entire human body. Then you’ve got the gluteus medius and minimus sitting on the sides. If you only focus on one, you’ll never get that rounded, full look.
The gluteus maximus is the powerhouse. It handles hip extension. When you’re standing up from a chair or sprinting, that’s the maximus doing the heavy lifting. The medius and minimus are responsible for abduction—moving your leg away from the midline—and stabilization. If you want width, you have to target the sides. If you want depth and "pop," you have to hammer the maximus.
Why Your "Glute Amnesia" is Real
Ever heard of "dead butt syndrome"? Doctors actually call it gluteal amnesia. It sounds fake, but it’s a legitimate issue for anyone with a desk job. When you sit all day, your hip flexors get tight and short. This causes a phenomenon called reciprocal inhibition. Basically, your brain "forgets" how to fully engage the glutes because the opposing muscles (the hip flexors) are constantly switched on.
Before you even pick up a weight, you have to wake these muscles up. Dynamic stretching and bird-dogs aren't just "warm-ups" for the sake of it; they are neurological resets. Without them, your lower back and hamstrings will take over the lift, leaving your glutes exactly the same size they were when you started.

The Holy Trinity: Squats, Hinges, and Thrusts
If you ask ten different trainers how do you make your buttocks bigger, nine of them will mention the Hip Thrust. And they’re right. Dr. Bret Contreras, often called "The Glute Guy," has published peer-reviewed research showing that the hip thrust produces significantly higher muscle activation in the glutes compared to the traditional back squat.
Why? Because of the force vector. In a squat, the greatest tension is at the bottom when the muscle is stretched. In a hip thrust, the greatest tension is at the top when the muscle is fully contracted (shortened).
- The Hip Thrust: This is the king. Use a barbell. Get a pad for your hips—trust me, you’ll need it once you start moving real weight.
- The Romanian Deadlift (RDL): This targets the "glute-ham tie-in." Focus on pushing your hips back toward the wall behind you rather than just reaching for the floor.
- The Bulgarian Split Squat: Everyone hates these. They’re painful. They make your lungs burn. But because they are unilateral (one leg at a time), they force the glute medius to stabilize your entire pelvis. This is how you fix imbalances.
Don't just go through the motions. You need progressive overload. If you lift the same 15-pound dumbbells every week for a year, your glutes will stay the exact same size. You have to add weight, add reps, or decrease rest time. Your body is efficient; it won't build expensive muscle tissue unless it absolutely has to.
You Cannot Build a House Without Bricks
This is where most people get it wrong. You cannot build muscle in a calorie deficit. Period.
I see it all the time: someone wants a bigger butt but they’re also trying to "get shredded" for summer. You’re pulling the body in two different directions. To create new muscle tissue, your body needs an energy surplus. You need to eat.
Specifically, you need protein. Muscle protein synthesis requires amino acids, primarily leucine. Aim for about 0.8 to 1 gram of protein per pound of body weight. If you weigh 150 pounds, hitting 150 grams of protein a day is actually kinda hard if you aren't intentional about it. Chicken, Greek yogurt, lentils, and whey are your friends.

Carbs Are Not the Enemy
Glycolysis is the primary energy system used during resistance training. If you’re on a keto diet or a "low carb" kick, your workouts will likely suffer. You won't have the explosive power needed to push through a heavy set of squats. Plus, carbohydrates trigger an insulin response, which is highly anabolic (muscle-building). Eat a sweet potato. Have some rice. Your glutes need the fuel to recover.
The Role of Supplements and "Quick Fixes"
Let’s talk about the elephant in the room: Brazilian Butt Lifts (BBLs) and "butt enhancement" creams.
Creams don't work. There is no topical lotion that can magically stimulate muscle growth or selectively deposit fat in your buttocks. It’s a scam. Save your money.
BBLs, on the other hand, are the fastest-growing cosmetic surgery in the world. They involve taking fat from the stomach or thighs and injecting it into the glutes. While the results are immediate, the risks are significant. According to the American Society of Plastic Surgeons, the BBL has historically had one of the highest mortality rates of any cosmetic procedure due to the risk of fat embolisms. While safety protocols have improved, it’s a major surgery with a long recovery.
If you choose the natural route, creatine monohydrate is one of the few supplements actually backed by thousands of studies. It helps your muscles draw in water and increases ATP production, allowing you to squeeze out those last two reps that actually trigger growth. It won't make you "bulky"; it’ll just make you stronger.
Rest is Where the Growth Happens
You don't grow in the gym. You grow while you sleep.

When you lift heavy, you create microscopic tears in the muscle fibers. Your body then rushes to repair those tears, making the fiber slightly thicker than it was before. This is hypertrophy. If you train your glutes every single day, you’re never giving that repair process a chance to finish. You’re just digging a deeper hole of fatigue.
Three days of dedicated glute work per week is usually the sweet spot. Give yourself at least 48 hours between heavy sessions. And get your eight hours of sleep. Growth hormone peaks during deep sleep stages; if you’re pulling all-nighters, you’re essentially sabotaging your own gains.
Common Mistakes That Kill Progress
Sometimes it's not about what you're doing, but what you're doing wrong.
- Too much cardio: If you’re running five miles a day, your body is prioritizing cardiovascular endurance, not muscle size. High-intensity interval training (HIIT) is better for maintaining muscle, but even then, keep it moderate.
- Poor mind-muscle connection: If you feel your quads burning during a hip thrust but feel nothing in your butt, your form is off. Squeeze your glutes at the top like you’re trying to hold a coin between your cheeks. It sounds silly, but the internal cueing matters.
- Lack of consistency: You can't do "Leg Day" once every two weeks and expect results. It takes months of consistent effort to see visible changes in muscle volume.
Actionable Steps for the Next 30 Days
If you’re serious about making your buttocks bigger, stop searching and start doing. Here is the blueprint.
First, calculate your TDEE (Total Daily Energy Expenditure). Once you have that number, add 200–300 calories to it. That is your new daily goal. Don't guess; track it for at least two weeks so you get a feel for what that much food actually looks like.
Next, pick four foundation movements: The Barbell Hip Thrust, the Goblet Squat, the Walking Lunge, and the RDL. Perform these two to three times a week. Focus on "tempo." Take three seconds to lower the weight, and one second to explode up. This increases "time under tension," which is a primary driver for hypertrophy.
Finally, take progress photos and measurements. The scale is a liar. Muscle is denser than fat, so you might actually gain weight while looking leaner and "curvier." Trust the mirror and the fit of your jeans more than the numbers on the scale.
Building a better physique is a marathon. There are no shortcuts that don't involve a surgeon's scalpel. But with the right stimulus and enough fuel, your body will change. It has no choice but to adapt to the stress you put on it.
