What Are Hip Thrusts? Key Information

Hip thrusts are a strength training exercise that targets the glute muscles. You sit on the floor with your upper back resting on a bench, place a loaded barbell across your hips, and drive your hips upward until your body forms a straight line from shoulders to knees. This movement builds glute strength, power, and size. It is widely used by athletes, fitness enthusiasts, and people recovering from injuries.

How Are Hip Thrusts Different From Glute Bridges?

Glute bridges and hip thrusts look similar but have key differences. In a glute bridge, both shoulders and feet stay on the floor, and you lift your hips upward. In a hip thrust, your upper back rests on a bench, which allows a greater range of motion. Your hips can rise higher because the bench supports your shoulders, letting your thighs move past parallel to the floor.

The bench also lets you load the movement with more weight. Most people can hip thrust more than they can bridge because the bench provides a stable anchor for the upper body. This makes hip thrusts a more effective exercise for building maximum strength and muscle in the glutes.

What Muscles Does the Hip Thrust Work?

The primary muscle is the gluteus maximus, the largest muscle in your buttocks. It extends the hip joint, which is the main action of the hip thrust. The gluteus medius and minimus (smaller glute muscles) also activate to stabilize the pelvis.

Secondary muscles include the hamstrings (back of the thigh), which assist in hip extension. The adductors (inner thigh) help stabilize the legs, and the core muscles engage to keep the torso steady. The erector spinae muscles in the lower back work isometrically to prevent spinal flexion. No muscle works alone, but the hip thrust heavily targets the glutes with less spinal load than squats or deadlifts.

What Are the Benefits of Hip Thrusts?

Research consistently shows that hip thrusts produce high activation of the gluteus maximus compared to many other exercises. This makes them useful for building glute size and strength. Stronger glutes can improve athletic performance in running, jumping, and sprinting by providing more hip power.

Another benefit is reduced compression on the lumbar spine. Because your upper back is supported by a bench, the weight does not push down directly on your spine as it does during a squat or deadlift. For people with lower back discomfort who still want to strengthen their hips, hip thrusts offer a safer alternative — though you should always check with a healthcare provider before starting any exercise program.

Some evidence suggests that hip thrusts can improve hip extension strength, which may help with posture and walking mechanics. However, no large trials have confirmed long-term injury prevention benefits from this exercise alone. The evidence is strongest for muscle activation and hypertrophy (growth).

How Do You Perform a Hip Thrust Correctly?

Start by sitting on the floor with your upper back against a flat bench. Place a padded barbell across your hips, or use a dumbbell or resistance band if you are a beginner. Roll the barbell into position directly over your hip crease. Use a barbell pad or a folded towel to reduce discomfort.

Plant your feet flat on the floor about shoulder-width apart. Your shins should be vertical when you lift. Drive through your heels and lift your hips upward until your thighs are parallel to the floor — sometimes slightly above parallel if you have the flexibility. Squeeze your glutes at the top for one second. Lower your hips slowly under control.

No single rep count is right for everyone. A typical strength program uses sets of 8 to 12 repetitions with enough weight that the last two reps are very challenging. Start with bodyweight or very light weight to master the form. As with any loaded movement, increase weight gradually.

Are Hip Thrusts Safe? Common Mistakes and Risks

Hip thrusts are generally safe when performed correctly. The most common mistake is arching your lower back at the top of the movement. This puts excessive stress on the lumbar spine instead of the glutes. Keep your ribs down and your core braced so your pelvis stays neutral.

Another mistake is letting your knees flare outward or your feet slide inward. This reduces glute activation and can stress the knees. Keep your feet flat and your knees tracking over your toes.

Using too much weight too soon is a risk. The barbell can roll onto your stomach or hips if it is not secured with weight plates and collars. Always use safety collars. Ensure the bench is stable and will not tip. If you have existing hip, knee, or back injuries, consult a physical therapist before adding heavy hip thrusts to your routine. No clinical guidelines currently exist for specific rep ranges or loads for injured populations.

Who Should Do Hip Thrusts? Who Should Avoid Them?

Most healthy adults can benefit from hip thrusts. They are popular among runners, cyclists, and athletes in sports that require hip power. People with weak glutes from prolonged sitting may find hip thrusts helpful for activating the muscles. For older adults, hip thrusts can improve hip strength and stability, which may reduce fall risk — though more research is needed to confirm this.

Avoid hip thrusts if you have an acute lower back injury, a recent hip fracture, or a herniated disc that flares up with hip flexion. If you have knee pain when bending your hip and knee simultaneously, try a smaller range of motion first or use a lighter load. Pregnant women should check with their doctor before performing hip thrusts in the second or third trimester, especially if lying on the back causes dizziness or discomfort. The evidence here is limited, and individual conditions vary widely.

What Are Hip Thrusts? Key Information

Hip thrusts are a bench-supported glute exercise that emphasizes hip extension. They are distinct from glute bridges because the bench allows a larger range of motion and heavier loads. The movement primarily works the gluteus maximus, with support from the hamstrings, adductors, and core. Benefits include improved glute strength and size with less spinal compression than squats or deadlifts. Proper form requires a neutral spine, vertical shins, and controlled movement. While generally safe, beginners should start light and progress slowly.
