Single Leg Hip Thrust: A Complete Guide

Quick Intro

Single Leg Hip Thrust, also called the Single Leg Glute Bridge, is a compound strength exercise performed by resting the upper back on a bench, extending one leg straight out in the air and driving the hips upward through the single grounded leg to a full lockout. It’s a unilateral glute and stability exercise that needs no equipment at its base, with dumbbells as an optional add-on.

Equipment Needed

Single Leg Hip Thrust needs No Equipment to perform, since bodyweight alone is a challenge through one leg at a time. A single Dumbbell is optional, held across the hips once the bodyweight version stops feeling hard.

Why Single Leg Hip Thrust Matters

Driving the hips up through one grounded leg is powered mainly by the seat (gluteus maximus), with the outer hip (gluteus medius) working considerably harder here than in a two-leg hip thrust, since it alone has to stop the pelvis from rotating open toward the lifted leg. The back of the thigh (hamstrings, biceps femoris) assists the hip extension, and the deep core (transverse abdominis) braces hard to keep the hips square throughout. Strength and endurance are asked for in equal measure, since removing one leg roughly doubles the demand on the working side, and balance comes with them because one hip has to hold the pelvis level.

When to Do It

Single Leg Hip Thrust works well as a main or secondary unilateral exercise in a lower body session, placed once the two-leg hip thrust pattern already feels solid and a balance and stability challenge is wanted. Two sessions a week, with recovery time between hard sets, gives the working hip time to adapt.

Anyone with a current hip flexor strain or lower back sensitivity should approach this lift with caution, since one leg alone has to control both the lockout and the pelvis’s rotation. Starting with bodyweight only and a shorter range of motion is a reasonable way to learn the pattern before adding a dumbbell.

Getting Ready

Two-leg glute bridges for a few reps groove the basic lockout position before narrowing the base to one leg. Standing on one leg for a few seconds at a time, simply getting used to single-leg balance, is worth doing before the first rep.

Once the pattern feels stable on both sides, a lighter first set with a shorter range of motion lets the hip adjust to the unilateral demand before the working sets begin.

Step-by-Step Instructions

1. The setup. Sit on the floor with the upper back against a bench, one foot flat on the floor, the other leg extended straight out in the air.

2. The brace. Pull the ribcage down toward the hips and set the spine in a neutral, braced position before driving with the leg at all.

3. The drive. Drive through the heel of the grounded foot to raise the hips, keeping the extended leg still and in line with the torso.

4. The lockout. Hold the top position briefly, keeping the hips square and level rather than letting them rotate toward the lifted leg.

5. The lower. Lower the hips back down under control, then complete all reps on one side before switching legs.

How Many, How Often

Single Leg Hip Thrust is dosed by reps, sets and, once bodyweight feels manageable, the weight of an optional dumbbell, with the working weight or rep count chosen relative to how well the hips stay square through a full set.

Keeping the extended leg still and in line with the torso and driving through the heel of the grounded foot without letting the hips rotate open matters more here than the weight added, since hip rotation toward the lifted leg is the clearest sign the outer hip has stopped stabilizing.

Modifications and Variations

Single Leg Hip Thrust has a single easier entry point, the two-leg lift.

For an easier entry point that splits the load across both legs, Barbell Hip Thrust rests a loaded barbell across the hips with both feet grounded, removing the single-leg balance and rotation-control demand this version specifically adds.

Progression path: Barbell Hip Thrust as a two-leg foundation → Single Leg Hip Thrust once a heavy two-leg lockout feels solid and a single-leg challenge is wanted.

Common Mistakes to Avoid

Letting the hips rotate open toward the lifted leg. It’s the clearest sign the outer hip has stopped doing its job: rotation toward the extended leg means the pelvis is twisting instead of staying square under the working hip. Bracing the core and consciously keeping both hip points level throughout keeps the lockout square.

Letting the extended leg drop or wobble. An extended leg that sags toward the floor or swings around adds unnecessary instability and pulls focus away from the working hip. Keeping that leg still, straight and roughly in line with the torso throughout the set keeps the movement controlled.

Rushing to add weight before bodyweight is controlled. Adding a dumbbell before the hips can stay square through a full bodyweight set just amplifies the same compensation with added load. Mastering a clean, level bodyweight lockout on both sides first is worth more than an early jump to loading.

After Your Set

This lift raises the heart rate a bit more than its two-leg counterpart, since balancing on one leg adds effort, so a minute or two of easy walking helps it settle before stretching begins. Kneeling in a half-kneeling stance and pressing the hips gently forward opens the hip flexor on the leg that stayed extended in the air through the set. Sitting and pulling one knee toward the chest, holding briefly, releases the working glute on each side in turn.

Going Deeper

Single Leg Hip Thrust usually sits as a step up once the two-leg hip thrust pattern is solid, adding a single-leg stability demand that carries over to sprinting, single-leg jumps and any sport built around one-leg power. Pairing it with other single-leg work, like a split squat or a step-up, later in the session builds unilateral strength across the whole leg.

Progress here tends to stall on hip control, not raw glute strength: as reps or weight increase, it becomes tempting to let the pelvis rotate open to finish the lockout, which quietly shifts the work off the outer hip and onto the lower back instead. Slowing the tempo and reducing the range slightly while rebuilding a square-hipped lockout tends to fix a stalled single leg hip thrust faster than pushing through with a compensating pattern.

Someone new to this lift generally needs a few sessions to find balance and control on the weaker side specifically, and works up to a loaded dumbbell set once both sides can complete a full, controlled set somewhere in the four to six week range.

How to Know You’re Improving

1. Hips that stay square and level through the entire lockout on both sides
2. An extended leg that stays still and controlled throughout the set
3. A noticeably smaller strength gap between the left and right hip over time
4. A dumbbell added once bodyweight reps feel easy on both sides

Hips that stay level on both sides, not the weight added, is what marks progress here.

Muscles Worked

• Gluteus Maximus (the largest glute muscle, extending one hip with the whole bodyweight on it)
• Gluteus Medius (a smaller glute muscle at the side of the hip, stopping the free side of the pelvis dipping as the hips lift)
• Biceps Femoris (a muscle at the back of the thigh, assisting the single working hip to full extension)
• Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, keeping the pelvis square with one leg in the air)

FAQ

Is Single Leg Hip Thrust harder than the two-leg version? Yes, it’s a harder variation of Barbell Hip Thrust, since removing one leg roughly doubles the demand on the working hip and adds a balance and rotation-control challenge the two-leg version doesn’t have (see Modifications and Variations above).

Why does one side feel noticeably weaker than the other? This is common and simply reflects a strength or stability difference between hips that a two-leg lift can hide. Training the weaker side first, while it’s freshest, is a reasonable way to close that gap over time.

Do I need a dumbbell for this exercise? No. Any added load here is optional, since a bodyweight set on one leg already provides a challenge for most lifters.

Why do my hips twist as the set goes on? This almost always means fatigue is setting in and the outer hip is losing its ability to keep the pelvis square (see Common Mistakes above). Reducing the reps slightly or dropping any added weight tends to restore control.
