How to Fix a Flat Butt and Build Rounder Glutes
If you have a flat butt, you probably are not looking for a long anatomy lesson. You want to know what exercises actually work.
Maybe your jeans do not fill out the way you want. Maybe you look in the mirror and feel like there is not much shape there. Or maybe you are comparing yourself to girls who seem to naturally have round glutes and wondering what you can actually do about it.
The good news is this does not need to be complicated.
If you are not really training your glutes right now, start with two main exercise types:
- A hip thrust or glute bridge variation
- A step-up or lunge variation
That alone can take you pretty far if you train hard enough, progress over time, and eat in a way that supports muscle growth.
Quick Answer: What Exercises Fix a Flat Butt?
The best exercises to start fixing a flat butt are a hip thrust or glute bridge and a step-up.
A hip thrust or bridge trains the glute max, which is the main muscle that gives your butt size, fullness, and projection. A step-up trains the glutes one leg at a time and helps build shape, control, and strength.
If you want to keep it simple, start here:
Exercise 1: Hip thrust or glute bridge Exercise 2: Step-up
That is the beginner answer.
If you want a more complete glute plan, build your workouts around four movement patterns:
- Thrust variation
- Squat or lunge variation
- Hinge or pull variation
- Abduction variation
You do not need 20 random exercises. You need a few good movements from those categories, and you need to get better at them.
What Is a Flat Butt?
A flat butt usually means there is less visible glute projection, fullness, or roundness from the side or back. Some people call it a pancake butt, small butt, no butt, or flat glutes. It is one of the common butt shapes, and it is also one of the most trainable.
Nothing is wrong with having a flat butt. But if your goal is to build more shape, the main thing you need is more glute muscle.
For most people, that means building the glute max first. The glute max gives your butt most of its size, fullness, and projection. The glute medius and minimus help round out the sides, but they are not the main builders if your biggest issue is flatness.
Think of it like this:
The glute max builds the butt.
The glute medius helps round out the sides.
You want both, but the glute max is the main focus.
Why Your Butt Looks Flat
Your butt may look flat for a few reasons. Genetics can play a role. Some people naturally store less fat in their glutes. Some people naturally have less projection from the side. Posture, pelvis structure, training history, and muscle size can all affect how your glutes look.
But if you have never really trained your glutes consistently, the biggest reason may be simple:
You have not built enough glute muscle yet.
That is not a personal failure. That is just the starting point.
If you train your glutes with the right exercises, eat enough to support growth, and stick with it, you can build more fullness and shape over time. If you want the deeper explanation of how glutes actually grow, start there.
The Two Best Exercises to Start With
If you are newer to training, start with a thrust or bridge variation and a step-up.
That is simple, and simple is good when you are actually trying to be consistent.
1. Hip Thrust or Glute Bridge
The hip thrust or glute bridge is your main thrusting movement. This trains the glute max directly and helps build more projection from the side.
If you have a bench, do hip thrusts. If you do not have a bench, do glute bridges from the floor. If you have a dumbbell, barbell, Smith machine, or hip thrust machine, use what you have available.
Do not overthink it.
Pick the version you can do well and progress.
A hip thrust is usually easier to load heavier over time. A glute bridge is simpler and more beginner-friendly. Both can work.
Simple cue: Keep your ribs down, control your pelvis, and finish the rep with your glutes. Do not just arch your lower back and call it a rep.
2. Step-Up
The step-up is the main single-leg exercise I would recommend for a flat butt.
You could also use lunges, deficit lunges, or Smith machine lunges, but for most beginners, step-ups are easier to understand and easier to make glute-focused.
A good step-up trains the glutes one leg at a time. It helps build strength, shape, and control.
To make step-ups more glute-focused, use a box or bench that is high enough to challenge you but not so high that your form falls apart. Lean forward slightly, drive through the working foot, and try not to push off the back leg too much.
Simple cue: Make the front leg do the work. Step up with control and lower slowly.
Do You Need More Than Two Exercises?
Not at first.
If you are not training your glutes right now, hip thrusts or bridges plus step-ups can be enough to start seeing progress.
But if you really want to grow your glutes and build a more complete workout, use the four main glute movement patterns.
1. Thrust Variation
This is your hip thrust or glute bridge pattern.
Good options:
- hip thrust
- glute bridge
- Smith machine hip thrust
- machine hip thrust
This is usually your main glute max builder.
2. Squat or Lunge Variation
This is your single-leg or deeper glute movement.
Good options:
- step-up
- reverse lunge
- Bulgarian split squat
- Smith machine deficit lunge
For this article, I would keep the main recommendation simple: step-ups. They are easy to understand, easy to progress, and great for building glutes when done right.
3. Hinge or Pull Variation
This trains the glutes in a stretched position and helps build the backside from a different angle.
Good options:
- Romanian deadlift
- dumbbell RDL
- cable pull-through
- glute-biased back extension
You do not have to start here if you are a beginner, but this is a strong category to add when you want a more complete glute program.
4. Abduction Variation
This trains the side glutes and helps round out the shape.
Good options:
- seated hip abduction
- cable hip abduction
- side-lying abduction
- banded lateral walk
Abductions are not the main answer for a flat butt, but they are a good add-on. The glute max gives you the main size and projection. Abductions help round out the sides. For more options here, see our guide to glute accessory exercises.
Simple Flat Butt Workout
If you want the easiest version, start with this 2 days per week.
| Exercise | Sets | Reps | Focus |
|---|---|---|---|
| Hip thrust or glute bridge | 3 to 4 | 8 to 12 | Glute max size and projection |
| Step-up | 3 to 4 | 8 to 12 per side | Single-leg glute growth |
That is the simple beginner plan.
If you want the more complete version, use the four movement patterns.
| Movement Pattern | Exercise | Sets | Reps |
|---|---|---|---|
| Thrust | Hip thrust or glute bridge | 3 to 4 | 8 to 12 |
| Squat/Lunge | Step-up | 3 to 4 | 8 to 12 per side |
| Hinge/Pull | Romanian deadlift | 3 | 8 to 10 |
| Abduction | Seated hip abduction | 2 to 3 | 15 to 25 |
You do not need to do every glute exercise on the internet. This already covers the main things your glutes need.
How Often Should You Train Glutes for a Flat Butt?
Train glutes 2 to 3 times per week.
If you are a beginner, start with 2 days per week. That gives you enough practice and enough recovery.
If you really want to grow faster and you recover well, you can train glutes 3 days per week. Just do not turn every workout into a random 15-exercise glute marathon.
| Frequency | Best For | Focus |
|---|---|---|
| 2 days per week | Beginners | Simple growth and recovery |
| 3 days per week | More intense glute growth | More weekly volume and practice |
The goal is not to destroy your glutes every workout. The goal is to train them hard enough, recover, and come back stronger.
2-Day Glute Plan for a Flat Butt
If you want to train glutes twice per week, keep it simple.
Day 1
| Exercise | Sets | Reps |
|---|---|---|
| Hip thrust or glute bridge | 4 | 8 to 12 |
| Step-up | 3 | 8 to 12 per side |
| Seated hip abduction | 3 | 15 to 25 |
Day 2
| Exercise | Sets | Reps |
|---|---|---|
| Hip thrust or glute bridge | 3 | 10 to 12 |
| Romanian deadlift | 3 | 8 to 10 |
| Step-up | 3 | 8 to 10 per side |
This is enough for a lot of beginners. You are training the thrust pattern, step-up pattern, hinge pattern, and side-glute pattern without making the workout a whole science project.
3-Day Glute Plan for a Flat Butt
If you want to train glutes 3 times per week, use the same basics with slightly different emphasis.
Day 1: Thrust and Step-Up
| Exercise | Sets | Reps |
|---|---|---|
| Hip thrust or glute bridge | 4 | 8 to 12 |
| Step-up | 3 | 8 to 12 per side |
| Hip abduction | 3 | 15 to 25 |
Day 2: Hinge and Glute Max
| Exercise | Sets | Reps |
|---|---|---|
| Romanian deadlift | 3 to 4 | 8 to 10 |
| Hip thrust or glute bridge | 3 | 10 to 12 |
| Cable kickback | 3 | 12 to 15 per side |
Day 3: Step-Up and Side Glutes
| Exercise | Sets | Reps |
|---|---|---|
| Step-up | 4 | 8 to 10 per side |
| Hip thrust or glute bridge | 3 | 10 to 12 |
| Seated hip abduction | 3 | 15 to 25 |
You can grow with 3 days per week, but only if you are recovering. If your form gets worse, your soreness is too much, or you are dragging through the workouts, go back to 2 days and get stronger there first.
Nutrition Matters If You Want to Grow Your Butt
If you want to build your butt, training is only part of it.
You also need to eat in a way that supports muscle growth.
A simple protein target is around 0.7 grams of protein per pound of body weight. You do not have to force 1 gram per pound. Around 0.7 grams per pound is a solid, realistic target for most people.
So if you weigh 150 pounds, that would be around 105 grams of protein per day.
Protein matters because it gives your body the building blocks to build muscle.
But do not ignore carbs.
Think of it like building a house. Protein is the bricks. Carbs are the builders that help put the bricks in place.
You need both.
If you are training hard but barely eating, your body may not have enough resources to grow your glutes. You do not need to eat everything in sight, but you do need enough protein, enough carbs, and enough total food to support the goal.
Good protein options:
- chicken
- turkey
- eggs
- Greek yogurt
- lean beef
- fish
- protein powder
- tofu
- beans
Good carb options:
- rice
- potatoes
- oats
- fruit
- pasta
- bread
- tortillas
- cereal
The workout tells your glutes to grow. Food helps make that happen. For more on eating to support glute growth, see our nutrition guides.
Why Your Butt May Still Look Flat Even If You Work Out
If you are working out and your butt still looks flat, there are usually a few reasons.
Maybe you are not training hard enough. Maybe you are only doing band exercises. Maybe you are changing workouts every week. Maybe you are not eating enough. Maybe you feel everything in your quads, hamstrings, or lower back instead of your glutes.
Most of the time, the answer is not adding more random exercises.
The answer is getting better at the basics.
Pick a hip thrust or bridge. Pick a step-up. Add a hinge and abduction if you want the full plan. Train 2 to 3 times per week. Eat enough. Progress over time.
That is not flashy, but it works.
Common Mistakes When Trying to Fix a Flat Butt
Making It Too Complicated
You do not need a huge glute workout to start growing. If you are new, start with hip thrusts or bridges and step-ups. Get good at those first.
Only Doing Band Exercises
Bands can help, but they should not be the whole plan. Band walks, donkey kicks, clamshells, and fire hydrants are not enough for most people who want more projection and fullness.
Not Eating Enough
If you want to grow muscle, you need food. Trying to grow your butt while barely eating is like trying to build a house with three bricks and good intentions.
Not Progressing
If you use the same weight, same reps, and same effort forever, your body may not have a reason to change.
Add reps. Add weight. Improve control. Make the basics better.
Expecting Fast Results
Glute growth takes time. You may feel stronger in a few weeks, but visible changes usually take months.
That does not mean it is not working. It means you have to stay with it long enough.
Final Takeaway
If you want to fix a flat butt, do not make it more complicated than it needs to be.
Start with a hip thrust or glute bridge variation. Add step-ups. That alone can take you a long way if you are not currently training your glutes.
If you want the more complete plan, use four movement patterns: thrust, squat or lunge, hinge or pull, and abduction.
Train glutes 2 to 3 times per week. Eat enough protein and carbs. Progress slowly. Stay consistent long enough for your body to actually change.
You do not need every glute exercise on the internet. You need the right basics, done well, for long enough to work.
That is how you build the shelf.
