Why Are My Legs Growing but My Glutes Aren't Even Though I Do Squats

The Real Reason Your Squats Aren't Growing Your Glutes

The answer to 'why are my legs growing but my glutes aren't even though I do squats' is that for 80% of people, squats are a quad exercise first and a glute exercise second. You are not doing anything wrong; your body is just incredibly efficient. When you squat, it defaults to the strongest and most dominant muscle group to move the weight, which for most people is the quadriceps. This is called quad dominance, and it's the single biggest reason you feel a burn in your thighs while your glutes feel like they barely showed up. You can do 100 squats, go heavier, go deeper, and all you'll get are bigger quads because your specific biomechanics favor them in that movement pattern. It's frustrating because you're putting in the work, but the results are showing up in the wrong place. The truth is, squats are not the master glute-builder everyone claims they are. They are a fantastic overall leg developer, but if your goal is targeted glute growth, relying on squats is like trying to inflate a specific balloon in a bundle by blowing into the whole pack-you'll get some air in it, but most will go elsewhere.

Stop guessing if your glutes are working.

The Glute Growth Formula Squats Can't Deliver

To force a muscle to grow, you need three things: mechanical tension (lifting heavy), metabolic stress (the 'pump'), and muscle damage (soreness). The problem is, squats are an inefficient tool for applying these three things directly to your glutes. The primary function of your glutes is hip extension-driving your hips forward. The primary function of your quads is knee extension-straightening your leg. A squat involves both, but your unique anatomy, limb length, and mobility determine which one dominates. For most, the quads do 60-70% of the work, and the glutes just assist. A perfect glute-building exercise maximizes tension on the glutes when they are at their strongest: at the top of the movement, in full hip extension. In a squat, the tension on the glutes is highest at the bottom (the stretched position) and lowest at the top. An exercise like a barbell hip thrust is the exact opposite. It places almost zero tension on the glutes at the bottom and maximum, crushing tension at the top, right where the glutes are fully contracted. This is the key you're missing. You need to switch from a movement that *includes* the glutes to one that *isolates* them under maximum tension.

That's the science. Use exercises that create peak tension at the top of the movement. But knowing this and applying it are two different skills. Can you prove you are applying more tension to your glutes this week than you did 6 weeks ago? What was your 8-rep max on hip thrusts last month? If you don't know the exact number, you're not strategically building your glutes; you're just exercising and hoping for the best.

Your glute progress. All in one place.

Every workout logged. Proof you're building the strength that matters.

The 3-Step Protocol to Force Glute Growth

Stop being frustrated and start being strategic. For the next 8 weeks, forget everything you thought you knew about leg day. You are now on a glute-focused program. This means changing the order and selection of your exercises to force your glutes to do the work.

Step 1: Isolate to Initiate

Instead of warming up with squats, you will start every lower body workout with a glute isolation exercise. The goal here is to get a pump and pre-fatigue the glutes. This forces them to engage during the heavier lifts that follow because they're already 'turned on.' This isn't about 'activation'; it's about giving your glutes a head start so your quads can't immediately take over.

Your Action: Before any weighted exercises, perform 3 sets of 20-25 reps of Bodyweight Glute Bridges. Lie on your back with your knees bent. Drive through your heels, lift your hips, and squeeze your glutes as hard as humanly possible at the top for a full 2-second count. Do not rush. The burn is the goal.

Step 2: Replace Your Primary Squat with a Hip Thrust

This is the most important change. The squat is no longer your main lift. Your new primary movement is the Barbell Hip Thrust. This exercise directly trains hip extension and allows you to achieve peak tension where the glutes are strongest. This is non-negotiable.

Your Action: Perform 4 sets of 8-12 reps of Barbell Hip Thrusts. Place your upper back on a bench and a barbell across your hips. Drive the weight up by squeezing your glutes, achieving full hip extension (a straight line from shoulders to knees). Control the weight on the way down. Focus on adding weight or reps each week. A good starting point for women is 65-95 pounds; for men, 95-135 pounds. The goal is progressive overload here, not just feeling a burn.

Step 3: Use Squats as a Glute Accessory

Squats are not gone, they are just demoted. They are now a secondary exercise performed *after* your main glute work. With your glutes already fatigued from the hip thrusts, they will be forced to contribute more during the squat.

Your Action: After hip thrusts, perform 3 sets of 10-15 reps of Goblet Squats or Dumbbell Sumo Squats. Using a dumbbell allows for a more upright torso, which helps you sit back and engage the glutes more effectively than a heavy barbell squat might. The weight will be much lower than your previous squat max, and that is the point. Focus on depth (hips below knees) and controlling the movement, not lifting a massive load. This is now a finishing move, not the main event.

What to Expect (And When Your Jeans Will Feel Tighter)

Progress is slow, but with this targeted approach, it is predictable. Here is a realistic timeline of what you will experience if you follow the protocol 2-3 times per week and eat enough protein (around 0.8g per pound of bodyweight).

Weeks 1-2: You will feel an immediate, intense difference. The soreness will be concentrated in your glutes, not your quads. Your hip thrust weight will feel awkward, and your ego might take a hit from lowering your squat weight. This is normal. Focus entirely on form and feeling the right muscles work. You should be able to do 20-30% more weight on a hip thrust than you can on a squat, so don't be afraid to load the bar once your form is solid.

Month 1: The mind-muscle connection will be strong. You'll be able to squeeze your glutes on command during every rep. You should have added at least 10-20 pounds to your hip thrust. You won't see dramatic visual changes yet, but your glutes will feel firmer and look 'fuller,' especially after a workout. This is due to increased glycogen storage and blood flow.

Months 3-6: This is where the real, visible growth occurs. If you have been consistent with progressive overload and nutrition, you will see a noticeable change in the shape and size of your glutes. A 0.5 to 1-inch increase in your hip measurement is a realistic and fantastic outcome in this timeframe. Your pants will start to fit differently-tighter in the seat, but not necessarily in the thighs. This is the proof that your training is finally working for you, not against you.

Frequently Asked Questions

The Role of Mind-Muscle Connection

It's not magic; it's focused attention. For a hip thrust, actively think about driving your hips to the ceiling using only your glute muscles. At the top, imagine you're cracking a walnut between your cheeks. This conscious effort can increase muscle fiber recruitment in the target muscle by 10-15%, ensuring your glutes do the work, not your hamstrings or lower back.

Best Glute Accessory Exercises

After your main hip thrusts and squats, add one or two more exercises to hit the glutes from different angles. Top choices include Romanian Deadlifts (RDLs) for the stretch component, Cable Kickbacks for high-rep isolation work, and Bulgarian Split Squats to train each leg individually. Pick two and perform 3 sets of 12-15 reps.

How Often to Train Glutes for Growth

Train them 2 to 3 times per week. The glutes are a large, powerful muscle group that can handle and requires significant volume to grow. Spacing your workouts with at least 48 hours of rest is crucial for recovery and growth. A Monday/Thursday or a Tuesday/Friday lower body schedule works perfectly.

Why Your Squat Form Matters

If your first move out of the bottom of a squat is your hips shooting up, your lower back and hamstrings are compensating for weak glute engagement. To fix this, think 'chest up' and 'sit back' into the squat. Driving your knees out and pushing the floor apart with your feet will help activate your glute medius and improve stability, allowing for better overall glute contribution.

The Importance of a Calorie Surplus

You cannot build a house without bricks. To build new muscle tissue, you must be in a slight calorie surplus of 250-300 calories above your daily maintenance needs. Combined with adequate protein-at least 0.8 grams per pound of your bodyweight-this provides the fuel your body needs to repair and grow your glutes.
