Hip Thrust vs Squat vs RDL: Which Builds Glutes Fastest?

All three are great. But they're great for different reasons, and the order you should prioritize them in your glute training is not what most internet trainers tell you. Here's the ranking, with receipts.

If you've ever stared at three women in the gym doing three different glute exercises and wondered which one you should be copying, this post is for you. We're going to settle it.

The TL;DR: you need all three in your program, but they hit your glutes in different ranges of motion and different positions. Hip thrust gets the most direct glute activation. RDL recruits glutes through a deep stretch. Squat builds total lower body strength that supports both. Cut any one of them out and you're leaving growth on the table.

Now let's rank them.

The criteria: how we're judging

"Builds glutes fastest" is doing a lot of work in the headline of this post. Let's define it. We're rating each exercise on:

• Glute activation — how much your glutes actually fire during the lift (EMG data)
• Loadability — how heavy you can train it safely, week over week
• Beginner-friendliness — how easy it is to learn and not injure yourself
• Carryover — how much it contributes to other glute work

1. Hip thrust — the gold standard for direct glute activation

The hip thrust is the closest thing to a glute-isolation exercise that exists. EMG studies consistently show it produces higher gluteus maximus activation than the back squat — particularly through the top half of the movement, the lockout, which is where the glutes are most mechanically engaged.

Why it's #1 for glute activation: the resistance vector (vertical, against gravity) lines up perfectly with the line of pull of the gluteus maximus when you're flat on your back. Your glutes have to do basically all the work — there's no real way to "cheat" the movement with quads or lower back, the way you can during a squat.

Loadability: very high. Most women can comfortably hip thrust 1.5–2x their back squat once technique is dialed. A woman who back-squats 135 lbs can often hip thrust 225 lbs comfortably.

Beginner-friendliness: medium. The setup is the hardest part — most beginners struggle with bar position on the hips (use a pad) and rib flare (keep ribs down). The actual movement is intuitive.

Verdict: the single best direct-glute exercise. Put it in every glute program. If you only had one exercise for glute growth, this would be it.

2. Romanian deadlift (RDL) — the stretch-mediated growth king

The RDL hits the glutes through a deeply stretched position — and the recent research on "stretch-mediated hypertrophy" suggests training a muscle through a long range of motion (and pausing or loading in the stretched position) is one of the most potent drivers of growth we have.

Why it's a top-3 exercise: the bottom of an RDL puts the glutes (and hamstrings) under maximum stretch under load. This stretch position appears to drive growth signals that shorter-range exercises don't.

Loadability: high. RDLs typically use less weight than a conventional deadlift but can still be heavily loaded over time.

Beginner-friendliness: medium-hard. The hardest part is learning the hip hinge — most beginners turn it into a squat or round their lower back. If you can hinge properly, the RDL is one of the most growth-productive exercises that exists. If you can't, learn it before you load it heavy.

Verdict: non-negotiable in every serious glute program. Train it 1–2x per week, 3 sets of 8–10 reps.

3. Back squat (or front squat / goblet squat) — the foundation, not the centerpiece

Here's where most internet fitness content gets it wrong. Squats are an incredible lower-body exercise — but they are not primarily a glute exercise for most women.

The squat is dominated by the quadriceps for most lifters, with the glutes contributing through the bottom portion of the movement (the "hole"). EMG studies show glute activation during a heavy squat is real but considerably lower than during a heavy hip thrust.

Where squats matter for glutes: they build the total-body strength that lets you load hip thrusts and RDLs heavier over time. They also hit the gluteus medius (the side/upper portion of your glutes responsible for the "hourglass" shape) more than hip thrusts do, especially in wider stance variations.

Loadability: very high.

Beginner-friendliness: medium-hard. Mobility is the main barrier.

Verdict: include it, but as a supporting movement, not your only glute exercise. The biggest mistake intermediate women make is treating squats as their main glute lift. Hip thrust is the main glute lift. Squats support it.

The right ranking (which is also the wrong question)

If we have to rank them for pure glute growth:

1. Hip thrust — most direct glute activation, highest loadability per unit of recovery
2. Romanian deadlift — stretch-mediated growth, hits glutes + hamstrings together
3. Back squat — supports everything else, builds total lower-body strength

But this ranking is actually the wrong framing. The right framing: they each train glutes in a unique position and through a unique range of motion. To fully develop your glutes, you need all three. Hip thrust at the top, RDL through the stretch, squat through the bottom of the squat depth. Cover all three ranges and you maximize total glute development.

What about hip abductions, glute kickbacks, and bands?

Accessory work. Use them — they're great for hitting the gluteus medius (kickbacks, abductions) and pre-fatiguing glutes before heavy work (band activation). But none of them should replace the big three. They support, they don't lead.

How to put all three in a single week

Here's a simple two-day-a-week glute split that uses all three intelligently:

• Monday — hip thrust focus: heavy hip thrust (3×8), Bulgarian split squat, hip abduction
• Thursday — RDL + squat focus: Romanian deadlift (3×8), back squat (3×6), single-leg hip thrust, glute kickback

Two sessions. All three big exercises. Recovery built in. DUMPY Y2K's programs are structured exactly like this, with built-in progressive overload tracking on each lift so you actually see your hip thrust, RDL, and squat numbers climb together.

The takeaway

Hip thrust > RDL > squat for glute-specific activation. But cut any of them out and you've got a hole in your program. Train all three with progressive overload, recover between sessions, and your glutes will respond.
