How to Grow Glutes
Without Growing
Quads
Not all lower body exercises are equal — and the research is specific about which ones grow glutes, which ones grow quads, and exactly how to use each. Here is the science behind building the posterior chain you want.

The glute anatomy you need to understand first
The gluteal complex is not a single muscle — it is three distinct muscles with different locations, functions, and therefore different optimal training stimuli. Growing the glutes without growing the quads requires understanding which part of the glute you are targeting, because the exercises that develop each region are not the same.
The largest muscle in the body and the primary driver of glute shape, size, and power. Responsible for hip extension, external rotation, and (in the proximal fibres) hip abduction. Divided functionally into upper and lower portions — each responding slightly differently to exercise selection. The 2025 Frontiers in Physiology systematic review identified hip extension with external resistance as its primary hypertrophic stimulus.
Located on the upper outer hip. Primary function is hip abduction — moving the leg away from the body — and pelvic stabilisation during single-leg movements. Responsible for the rounded, wider appearance of the upper glute. Responds best to lateral and abduction-based movements rather than hip extension. Minimal quad involvement in its training.
The deepest and smallest of the three. Works in close conjunction with the gluteus medius for hip abduction and internal rotation. Contributes to pelvic and femoral stability. Rarely isolated in training — abduction movements that target the medius also recruit the minimus simultaneously.
Four muscles running down the front of the thigh — rectus femoris, vastus lateralis, vastus medialis, vastus intermedius. Primary function is knee extension. Maximally recruited during knee-dominant, vertically-loaded movements where the knee travels forward over the foot under load: squats, lunges, leg press, step-ups. The architectural difference from the glutes is the key to understanding exercise selection.
Force vectors: the single concept that changes your entire programme
The most important principle in glute-biased training is one that most gym programmes ignore entirely: the direction of the load vector relative to the body determines which muscles are maximally stimulated. This concept, developed extensively by Bret Contreras — widely credited as the architect of modern glute training science — explains why two lower body exercises can feel equally hard but produce completely different muscular results.
Vertical force vectors — loads applied downward through the spine, as in a squat, leg press, or lunge — place the greatest mechanical demand on the knee extensors (quadriceps). The further the knee travels forward under load, the greater the quad involvement. The hips are also loaded, but the geometric advantage of the quads in resisting vertical load means they dominate this movement pattern.
Horizontal force vectors — loads applied parallel to the torso, as in a hip thrust or cable pull-through — place peak mechanical demand on the hip extensors at the point of maximum hip extension. At full hip extension, the gluteus maximus is the primary mover. The knee is relatively stable in these movements, which dramatically reduces quad recruitment relative to the hip thrust's glute demand.
The force vector principle — Contreras et al., Journal of Applied Biomechanics, 2015
Vertical load vector exercises (squats) maximally challenge the knee extensors through greater knee flexion-extension range of motion under load. Horizontal load vector exercises (hip thrusts) challenge the hip extensors — specifically the gluteus maximus — at the point of full hip extension. The force vector is the primary determinant of which muscles receive the greatest mechanical tension, and therefore which muscles are most strongly stimulated to hypertrophy.
This is why simply training your lower body harder does not solve the quad-dominance problem. If your programme is built on vertical load vector movements — squats, leg press, lunges with forward knee drive — you will continue to grow quads preferentially, regardless of how much you believe you are "focusing on the glutes." The solution is structural: you need to replace vertical load exercises with horizontal load exercises as your primary glute stimulus.
What EMG and MRI studies actually show
Electromyography (EMG) measures electrical activity in muscles during exercise — a proxy for how hard each muscle is working. When combined with MRI-based hypertrophy measurements over training studies, the two together provide the most complete picture of exercise effectiveness. The data on glutes versus quads is now extensive enough to draw firm conclusions.
Critical nuance — Kassiano et al. 2024 / Contreras et al. 2023 (MRI study)
Hip thrusts produced significantly higher EMG activation across all gluteus maximus regions compared to squats. However — and this is the nuance that changes programming — when MRI was used to measure actual muscle growth over weeks of training, both exercises produced similar glute hypertrophy. Squats produced more quadriceps and adductor growth, while hip thrusts were more glute-specific with minimal non-glute thigh hypertrophy. EMG alone does not predict hypertrophy — but it does confirm the muscle specificity of each exercise.
The 2025 Frontiers in Physiology systematic review and meta-analysis (Krause Neto et al.) — covering 12 studies and multiple hypertrophy measurement methods — confirmed that both hip thrusts and squats significantly increase gluteus maximus thickness and volume. The key finding for those who want to grow glutes without growing quads: hip thrusts achieve comparable or superior glute growth to squats while producing dramatically less quadriceps hypertrophy. They are the more glute-specific tool.
Squats produced more quadriceps and adductor growth, while hip thrusts were more glute-specific with minimal non-glute thigh hypertrophy. If you want a glute-biased result without extra thigh size, hip thrusts become especially attractive.

A complete glute programme requires three categories of movement: shortened-position hip extension (peak tension at the top), lengthened-position hip extension (peak tension at the bottom, where the muscle is stretched), and abduction and rotation movements. Each category targets different aspects of the glute complex and together they produce complete development.
Category 1 — Shortened position: peak glute tension at full extension
Why it works: Horizontal load vector. Peak glute tension at full hip extension where the gluteus maximus has maximum mechanical advantage. The 2025 systematic review specifically highlighted this as the priority movement for gluteus maximus hypertrophy.
Quad involvement: Low to moderate — significantly lower than any squat variation.
Programming: 3–4 sets × 8–15 reps. 90–180 sec rest. Progressive overload weekly.
Why it works: Adding a band above the knees during the hip thrust recruits gluteus medius and minimus simultaneously through the abduction demand. A single exercise hitting glute max and medius with near-zero quad involvement.
Quad involvement: Very low.
Programming: 3 sets × 12–20 reps. Light to moderate band resistance. Excellent as a warm-up activation set before loaded work.
Why it works: Same horizontal vector as the hip thrust but reduced range of motion. Excellent as an activation exercise, with bands, or for those building up to the barbell variation.
Quad involvement: Very low.
Programming: Best used as an activation warm-up (2–3 sets × 15–20 reps) or as a high-rep finisher with band.
Why it works: Horizontal cable vector challenges the glutes through hip extension with minimal knee flexion. Good lengthened-position loading of the lower glute max where it transitions into a hinge pattern.
Quad involvement: Low.
Programming: 3 sets × 12–15 reps. Useful as a complement to hip thrusts in the same session.
Category 2 — Lengthened position: glutes loaded under stretch
Research increasingly shows that training a muscle in its lengthened position — where it is stretched under load — may be the most powerful hypertrophic stimulus available. For the glutes, this means hip hinge movements where the muscle is long and loaded simultaneously. These complement hip thrusts which load the glute in the shortened position.
Why it works: The RDL loads the lower gluteus maximus hardest in the stretched position — maximising the lengthened-position stimulus. A March 2025 evidence ranking placed the RDL in the top tier for lower glute hypertrophy, ahead of hip thrusts, due to sustained tension through the stretch.
Quad involvement: Very low — primarily hip hinge with knee soft but stable.
Programming: 3–4 sets × 8–12 reps. Focus on hips back, not torso down. Stop when glute tension begins to decrease at the bottom.
Why it works: Same lengthed-position stimulus as the RDL, plus the unilateral demand recruits the gluteus medius for pelvic stability. Excellent for developing the glute through its full functional range, addressing left-right imbalances, with zero quad dominance.
Quad involvement: Minimal.
Programming: 3 sets × 8–10 reps per side. Use dumbbells, cable, or barbell depending on stability level.
Why it works: Loads the glute max through a hip hinge pattern with the spine neutral. Can be loaded with a weight plate held at the chest. The glute is under meaningful tension through the mid and lower range of the movement.
Quad involvement: Very low.
Programming: 3 sets × 10–15 reps. Focus on initiating with glutes at the bottom rather than lower back at the top.
Why it works: Hip hinge pattern loaded with barbell or band, with the spine in a horizontal position at the bottom — creating a lengthened glute stimulus similar to the RDL. Builds lower glute max and teaches hip hinge mechanics that transfer to all posterior chain work.
Quad involvement: Very low when performed with proper hip hinge mechanics.
Programming: 3 sets × 10–15 reps. Keep soft knee throughout. Begin with band or light barbell.
Category 3 — Abduction and lateral: glute medius and upper glute width
Why it works: Directly loads the gluteus medius and minimus through their primary movement — hip abduction — with cable providing consistent tension throughout the range. The most targeted glute medius exercise available. Zero quad involvement.
Programming: 3 sets × 12–15 reps per side. Control the eccentric. Do not allow the pelvis to hike at the top.
Why it works: Isolates the glute medius through hip external rotation and abduction from a side-lying position. Excellent activation exercise and injury prevention tool. Add a band above the knee for progressive overload.
Programming: 2–3 sets × 15–20 reps. Best used as a warm-up or finisher rather than a primary loading exercise.
Why it works: Horizontal cable vector in single-leg hip extension. Directly targets glute max through the shortened-position range with near-zero quad involvement. The 2025 systematic review cited kneeling kickbacks as a key glute isolation exercise distinct from hip extension patterns.
Programming: 3 sets × 12–15 reps per side. Squeeze hard at full extension. Avoid lumbar hyperextension.
Why it works: Hip thrust variation performed with feet together and knees out in external rotation — maximally shortening the glute max fibres. Excellent as a high-rep finisher for glute max and medius with no bar required. Light load, high reps, strong mind-muscle connection.
Programming: 1–2 sets × 20–30 reps as a session finisher. Bodyweight or light band.
What to limit, modify, or avoid if quad growth is a concern
-
Limit
Barbell back squats (high bar). The exercise that most consistently drives quadriceps hypertrophy in research. High bar squats increase forward knee travel under load, maximising quad activation. If squats are included in a glute-dominant programme, low bar with a wider stance and emphasis on sitting back — rather than knee-forward — shifts load toward the posterior chain. MRI studies confirm squats grow quads significantly more than hip thrusts do.
-
Limit
Leg press. Vertically loaded, knee-dominant pattern. Even with feet high on the platform, the quad remains the primary mover through the range of motion. Including the leg press while avoiding quad growth is a contradiction — it is by definition a quad-dominant machine exercise.
-
Modify
Lunges and walking lunges. Forward-knee-drive lunges are quad dominant. However, a long-stride reverse lunge — where the back knee drops straight down and the front shin remains nearly vertical — significantly reduces knee travel over the foot, shifting load to the glutes and hamstrings. Reverse lunges and split squats performed with a more upright torso and intentional glute drive are far more glute-biased than standard forward lunges.
-
Modify
Step-ups. Standard step-ups with forward knee drive are knee-dominant. However, a lateral step-up or a step-up with deliberate hip hinge and glute drive at the top — pressing through the heel rather than the ball of the foot — can shift emphasis toward the glute. Foot placement on the step (heel-driven vs. toe-driven) is the key technical variable.
-
Avoid as primary
Hack squat machine. One of the most quad-isolating exercises available. The fixed forward-lean of the machine removes the posterior chain from the movement almost entirely. No meaningful role in a glute-dominant programme.
-
Modify
Bulgarian split squat. When performed with trunk upright and knee pushed forward, it is predominantly quad. When performed with a forward lean at the hip — effectively a split stance RDL position — it becomes significantly more glute-dominant. The same exercise with different torso angle produces a different primary muscle response. Choose the hip-hinge variation.
Technique cues that shift load from quads to glutes
Hip thrust foot position
Foot placement on the hip thrust dramatically affects which muscles dominate. Feet closer to the glutes increase hip flexion at the bottom, creating greater glute activation through the range. Feet wider than shoulder-width with slight external rotation (15–20 degrees of toe-out) increases gluteus maximus and medius recruitment while reducing quad involvement. Pressing through the heel, not the toes, maintains the hip-extension bias and prevents the movement from becoming knee-driven.
The posterior pelvic tilt cue
At the top of the hip thrust, consciously tucking the pelvis posteriorly — "scooping" the hips under — maximally shortens the gluteus maximus fibres and creates the peak contraction that drives glute-specific adaptation. Hyperextending the lumbar spine at the top instead — a common error — transfers load to the lower back and reduces glute recruitment at the critical top position.
The RDL hip hinge cue
In the Romanian deadlift, the instruction "push your hips to the wall behind you" rather than "lean forward" produces the correct movement pattern. The torso follows the hips rather than leading them. Stopping when the stretch sensation in the glutes begins to diminish — before the hamstrings take over completely — maintains glute tension through the set. Going too low sacrifices the glute stimulus for hamstring dominance.
Mind-muscle connection: it is not pseudoscience
Research has confirmed that consciously focussing on the target muscle during exercise — the mind-muscle connection — measurably increases EMG activation in that muscle. For glute training, actively squeezing the glutes at the top of each hip thrust, consciously contracting them at the bottom of each RDL, and deliberately engaging them before initiating each cable kickback increases glute-specific activation independently of load selection. This is not a coaching cue — it is supported neurophysiology.
Individual anatomy matters
Hip socket depth and orientation vary significantly between individuals and directly affect glute recruitment in any given exercise. Some people show high glute activation in squats due to their hip anatomy — they are the exception, not the rule. EMG research shows population-level trends, but individual variation is meaningful. If a particular exercise consistently produces more quad feel than glute feel despite correct technique, that is valid biological information. Prioritise exercises where you actually feel the glute working — this is both a technique and an anatomy signal.
The evidence-based glute programme: 3 days per week
Built on the research principles above: one shortened-position primary lift, one lengthened-position hip hinge, and one abduction movement per session — plus a finisher. No squats, leg press, or forward-knee-drive lunges. Progressive overload on the hip thrust and RDL is the primary growth driver.
Session A — Primary emphasis: Hip thrust + RDL
Performed on Day 1 of the training week
Session B — Primary emphasis: Single-leg work
Performed on Day 3 of the training week
Session C — Volume day: full glute complex
Performed on Day 5 of the training week
Progressive overload is non-negotiable
The programme structure is the foundation — but muscles only grow when they are progressively challenged with more load, more reps, or reduced rest over time. Track your hip thrust and RDL weights weekly. Add 2.5–5kg to the hip thrust when you can complete the top of the rep range with good form across all sets. This is the variable that separates consistent glute growth from maintenance at a comfortable plateau.
