You probably think you know your glutes. Most people do. They see a picture of a muscular backside and think, "Okay, that's just one big muscle I need to squat for." Honestly? That’s barely half the story. If you’re only chasing the gluteus maximus, you’re leaving your hip stability—and a lot of your actual "lift"—on the table. Your gluteus minimus is tiny, hidden, and incredibly annoying when it stops working right, yet it’s the secret to why some people can run forever without knee pain while others crumble after a mile.
We need to talk about the mechanics here.
The gluteus maximus is the king of the posterior chain. It’s the largest muscle in the human body by volume. When you stand up from a chair or sprint for a bus, that’s the maximus doing the heavy lifting. But the gluteus minimus? That’s the "side-glute" specialist located deep underneath the medius. It’s a fan-shaped stabilizer that keeps your pelvis from dropping like a stone every time you take a step. Without it, you’d waddle.
Why the Gluteus Maximus Isn't Just for Aesthetics
Most gym-goers treat the gluteus maximus like a trophy muscle. Sure, it looks great in jeans, but its real job is hip extension. It’s what keeps us upright. Evolutionarily speaking, humans developed these massive rumps so we could run and climb better than our primate cousins.
The muscle fibers of the maximus are unique. They are incredibly thick. They thrive on heavy loads. If you are just doing high-rep bodyweight pulses, you aren't really "speaking" to the gluteus maximus in a way it understands. It wants resistance. It wants to move weight through a full range of motion. Dr. Bret Contreras, often called "The Glute Guy," famously popularized the hip thrust because it targets the maximus at its shortest, most contracted point—something squats actually fail to do effectively.
But here is the catch.
If your hip flexors are tight from sitting at a desk for eight hours, your gluteus maximus literally can't fire properly. It’s called "reciprocal inhibition." Basically, the brain shuts down the glute because the muscle on the opposite side (the psoas) is stuck in a shortened state. You can squat until you’re blue in the face, but if those hips are locked, your lower back will take over the work. That’s how people end up with "pancake butt" despite working out every day.

The Tiny Giant: The Role of the Gluteus Minimus
Let’s shift gears to the little guy. The gluteus minimus.
You can’t see it. You can barely feel it unless it’s cramping. But man, does it matter. While the maximus handles the "go," the minimus handles the "stay." It’s an abductor. Its primary role is to pull the thigh away from the midline of the body and, more importantly, to stabilize the head of the femur in the hip socket.
Think about when you walk. For a split second, you are on one leg. In that moment, gravity wants to pull your opposite hip down. The gluteus minimus (along with its neighbor, the medius) says "no." It tenses up to keep your pelvis level. When this muscle is weak, you get "Trendelenburg gait." It’s that hip-drop walk that eventually leads to IT band syndrome and "runner's knee."
Research published in the Journal of Orthopaedic & Sports Physical Therapy has shown that people with hip osteoarthritis often show significant atrophy in the gluteus minimus specifically. It’s not just about looking "toned" on the sides; it’s about making sure your hip joint doesn’t grind itself into dust by age fifty.
Stop Squatting for Everything
Squats are great. They really are. But they are a mid-tier glute exercise.
There, I said it.

If your goal is purely gluteus maximus development, the squat is actually a quad-dominant movement for most people. Gravity pulls the weight down, and your knees take a huge chunk of the load. To truly hit the maximus, you need horizontal loading. Think deadlifts, kettlebell swings, and hip thrusts. These movements force the glutes to push forward, which is their primary mechanical advantage.
And for the gluteus minimus? Squats do almost nothing. To wake up the minimus, you have to move in the frontal plane. That means side-to-side. Most of us live our entire lives moving forward and backward. We walk forward, we sit down, we stand up. We rarely move laterally.
Have you ever tried a "monster walk" with a band around your ankles? Within thirty seconds, the sides of your hips start to burn like they’re on fire. That’s the gluteus minimus screaming. It’s a muscle that responds best to time under tension and constant stability challenges.
The Mind-Muscle Connection is Real (And Science Agrees)
Some people call it "bro-science," but the internal focus on a muscle during exercise actually changes the EMG (electromyography) output. A study out of the University of South Carolina found that when athletes focused specifically on squeezing their glutes during a lift, muscle activation jumped significantly compared to just "moving the weight."
The gluteus maximus is notoriously "sleepy." Because we sit on it all day, the neural pathways can get a bit dusty.
Try this: stand up right now. Try to squeeze just your right butt cheek. Now the left. If you can't do it without moving your legs or shifting your weight, your brain has lost the map to your glutes. You have "gluteal amnesia." You need to wake those pathways up before you go throw 200 pounds on a barbell, or you’re just going to hurt your back.
The Problem With "Glute Isolation"
We’ve seen a surge in "glute isolation" machines at the gym. The ones where you kick back or push out. They have their place, but they can be misleading.

The body doesn't like to work in isolation. The gluteus maximus works in a functional loop with the contralateral latissimus dorsi (the big muscle in your back). This is the posterior oblique sling. When you walk, your left glute and your right lat work together to transfer force across your spine. If you only train your glutes on a machine while sitting down, you aren't training them to do their job in the real world.
Real strength comes from integrated movements. A lunging movement with a torso twist is far more "functional" for the gluteus minimus than a seated abduction machine because it forces the muscle to stabilize the hip while the rest of the body is in motion.
Surprising Facts About Your Glutes
- The gluteus maximus is one of the few muscles in the body that isn't really used during relaxed walking on flat ground. You don't actually "turn it on" until you hit a certain speed or incline.
- Your gluteus minimus is actually a key internal rotator of the hip when the hip is flexed. This is why it feels different when you do side-lying leg raises with your toes pointed down versus pointed up.
- "Dead Butt Syndrome" is a real clinical term (sort of). It refers to gluteal tendinopathy, where the tendons of the minimus and medius become inflamed from too much compression—usually from sitting cross-legged or sleeping on a hard surface on your side.
How to Actually Build Them
If you want to stop guessing and start seeing progress, you have to vary the stimulus.
For the Maximus:
Focus on the "Big Three" of glute growth: Hip Thrusts, Romanian Deadlifts, and Bulgarian Split Squats. The split squat is particularly brutal because it forces the maximus to work at a deep stretch, which is a massive trigger for muscle growth (hypertrophy). Aim for a weight that makes you struggle by rep 10.
For the Minimus:
Incorporate "isometrics." Hold a single-leg stance while brushing your teeth. Do "clamshells," but don't just mindlessly flap your leg. Hold the top position for three seconds and feel the deep tissue in the hip socket engage. Use light resistance bands. The minimus doesn't need 100 pounds; it needs control and frequency.
Common Misconceptions That Kill Progress
- "I'll get too bulky." Honestly, the gluteus maximus is a massive muscle. "Bulking" it just makes it firm and powerful. It’s very hard to accidentally grow a "huge" butt without years of heavy lifting and a massive caloric surplus.
- "Sprints are enough." Sprints are amazing for power, but they are high-impact. If your gluteus minimus is weak, sprinting is a fast track to a stress fracture or a labral tear. You need the foundation first.
- "I feel it in my hamstrings, so it’s working." If you're doing glute bridges and your hamstrings cramp, your glutes aren't doing the work. You need to tuck your pelvis (posterior pelvic tilt) to "unhook" the hamstrings and force the glutes to take the load.
Actionable Plan for Better Hips
Start by auditing your daily movement. If you sit for more than four hours a day, your gluteus maximus is probably half-asleep.
Every sixty minutes, stand up and do ten glute squeezes. It sounds silly, but it keeps the neural connection alive. When you hit the gym, start with "priming." Spend five minutes doing lateral band walks to fire up the gluteus minimus before you ever touch a barbell. This pre-activation ensures that when you start your heavy sets, the right muscles are actually awake and ready to guard your joints.
Switch up your foot positioning too. Wide stance squats hit different fibers of the maximus than narrow stance. Rotating your feet slightly outward (external rotation) can help some people find their glutes easier because it aligns the muscle fibers with the line of pull.
Ultimately, stop treating your glutes like one big slab of meat. It’s a complex system of stabilizers and powerhouses. Treat the maximus like a weightlifter and the minimus like a tightrope walker. When you balance the raw power of the big muscle with the precision of the small one, your back pain disappears, your lifts go up, and yeah, you’ll probably need to buy new pants.
Focus on the squeeze. Control the descent. Stop sitting so much. Your hips will thank you in twenty years.
