You’ve seen the photos. One frame shows a flat, somewhat "pancake" profile, and the next—usually labeled twelve weeks later—shows a gravity-defying shelf that looks like it was sculpted by a Renaissance master. People post these bum before and after squats transformations on Instagram like they’re handing out candy. It makes you think that if you just drop your hips low enough for long enough, you’ll naturally end up with that same rounded result.
But honestly? Most of those photos are a mix of lighting, posing, and a very specific type of physiological response that doesn't happen overnight.
Squats are a foundational movement. They are the "king of exercises" for a reason. Yet, if you’re looking for a total glute overhaul, relying only on the standard back squat might actually leave you frustrated. Genetics play a massive role here. Some people have a high muscle insertion point, while others have a lower one, meaning the "shape" of your glutes is largely a blueprint you were born with. You can make the muscle bigger, but you can't change where it attaches to your bone.
The Science of the "After" Photo
When we talk about the gluteus maximus, we are talking about the largest muscle in the human body. It’s designed for explosive power. To get a visible change in a bum before and after squats comparison, you have to trigger hypertrophy. This isn't just "toning." I hate that word. Toning is a myth. What you're actually doing is damaging muscle fibers so they grow back thicker.
Dr. Bret Contreras, often called "The Glute Guy," has spent years using electromyography (EMG) to see which exercises actually fire up the glutes. Interestingly, his research shows that while squats are great, they actually involve a ton of quad and adductor (inner thigh) work. If you have "quad dominant" genetics, your legs might get huge while your glutes stay relatively the same. That’s why some people’s "after" photos show massive thighs but only a modest change in the rear.
You need mechanical tension. You need metabolic stress. And you definitely need muscle damage.
If you aren't adding weight to the bar, your "after" is going to look exactly like your "before." It’s called progressive overload. If you squat 50 pounds today and 50 pounds in six months, your body has no reason to build new tissue. It’s already adapted. You have to force it to change.
Why Your Squat Form Dictates Your Results
Most people squat wrong. They really do.
They stay too upright, or they don't go deep enough. To really target the glutes during a squat, you need hip flexion. The deeper you go—safely—the more the gluteus maximus is stretched under load. This "stretch-mediated hypertrophy" is a massive driver for growth. If you’re doing half-reps at the top, you’re mostly just working your quads.
Think about the "hinge."
Even in a squat, allowing the hips to travel back slightly (while keeping the spine neutral) puts more of the burden on the posterior chain. But there’s a limit. If you go too heavy too fast, your lower back starts taking over. Suddenly, your bum before and after squats journey turns into a "my lower back hurts" journey. Nobody wants that.
The Truth About Body Fat and Visibility
Let's get real for a second. You can have the strongest glutes in the world, but if they are covered by a certain layer of adipose tissue, you won't see that "sculpted" look. Conversely, if you are very lean but have no muscle, you’ll just have a flat profile. The best transformations usually involve two phases: a building phase where you eat enough protein to actually grow tissue, and a leaning phase where you reveal what you’ve built.
Most "miracle" 30-day squat challenges are a lie. Muscle tissue takes months to grow. If you see a massive change in four weeks, it’s likely a combination of a "pump" (blood rushing to the muscle), better posture, and maybe a really flattering pair of leggings.
Real change? That’s a 6-month to 2-year project.
Beyond the Basic Squat
If you want the "after" photo of your dreams, you have to diversify. The squat is a vertical push. But the glutes also work in horizontal planes.
- Hip Thrusts: These are arguably better for glute isolation than squats because the tension stays on the glutes at the top of the movement (the lockout).
- Bulgarian Split Squats: These are miserable. Everyone hates them. But because they are a single-leg movement, they force your gluteus medius (the side of your butt) to stabilize your pelvis. This creates that "rounded" look from the front and side.
- Romanian Deadlifts: This targets the "glute-ham tie-in." It’s that area where the bottom of the cheek meets the top of the thigh.
Variety matters because the glutes aren't just one muscle. You have the maximus, the medius, and the minimus. Squats hit the maximus hard, but they often neglect the others.
Common Pitfalls That Kill Progress
Sleep is a huge one. You don't grow in the gym; you grow in your bed. If you’re hitting the rack for heavy sets but only sleeping five hours a night, your cortisol levels will stay high, and your muscle protein synthesis will tank.
And then there's the food.

You cannot build a house without bricks. Protein is the brick. If you aren't hitting roughly 0.7 to 1 gram of protein per pound of body weight, your bum before and after squats progress will stall. You'll just get tired without getting bigger. It’s a common mistake—people start exercising and simultaneously cut their calories to "get toned," effectively starving the muscle they are trying to build.
Moving Forward: Your Action Plan
Forget the 30-day challenges. They are a recipe for tendonitis and disappointment. Instead, focus on a sustainable, high-intensity approach that treats your glutes like the powerful muscles they are.
- Prioritize Depth Over Weight: Stop ego-lifting. Drop the weight until you can get your hip crease below your knees. This deep stretch is what triggers the glute growth you're looking for.
- Frequency is Key: Hit your glutes 2-3 times a week. They are a large muscle group and can handle significant volume, provided you aren't maxing out every single session.
- Record Your Sets: You think your form is perfect, but it probably isn't. Film yourself from the side. Are your heels lifting? Is your back rounding? Fix the mechanics first.
- The Mind-Muscle Connection: It sounds like hippie talk, but it’s real. Squeeze your glutes at the top of the rep. Consciously "drive" through your heels. If you don't feel the burn in your glutes, you're likely letting your quads or back do the heavy lifting.
- Eat for Growth: Increase your protein intake immediately. Lean meats, eggs, Greek yogurt, or plant-based alternatives like seitan are your best friends. Without a slight caloric surplus or at least maintenance calories, your body won't have the energy to construct new muscle tissue.
- Track Your Measurements: Don't just rely on the scale. Use a measuring tape around the widest part of your hips. Sometimes the scale doesn't move because you're losing fat and gaining muscle simultaneously—the "holy grail" of body recomposition.
The road to a physical transformation is paved with boring, repetitive consistency. There are no shortcuts, no "one weird trick," and no magic supplement. Just heavy weight, good food, and the patience to wait for the biology to catch up to your ambition.
