Barbell hip thrust

Hip extension with your back on a bench and a bar across your hips — heavy loading with nothing asked of your spine or your grip.

What it is

Sit on the floor with your upper back against the long edge of a bench and a padded barbell across your hips. Knees bent, feet flat, heels roughly under your knees.

Drive through your heels and push your hips up until your body is horizontal from knees to shoulders and your shoulder blades are resting on the bench. Pause at the top. Lower under control.

The bench should catch you at about the bottom of the shoulder blades, so your upper back rolls on it rather than your neck.

What it demands

Hip extension against a large load, from gluteus maximus with the hamstrings and adductor magnus assisting.

Very little else, and that is the point: no grip demand, no spinal-position demand, no balance. It is the most isolated way to load hip extension heavily.

Enough tolerance for a bar across the hips, which is the practical limit for most people — a pad or a folded mat is not optional at real loads.

What usually goes wrong

Arching the lower back instead of extending the hips. The same error as the glute bridge and easier to fall into with weight on. At the top the ribs stay down and the line from knee to shoulder is straight, not curved.

Feet too far away, turning it into a hamstring movement, or too close, turning it into a quadriceps one.

The bench too high, so the shoulders are jammed up and the range is wrong.

Chasing weight past the point where the position holds. This movement accepts a lot of load, which is exactly why the position is worth watching.

Where it sits

The heaviest available hip extension without loading the spine, which makes it a genuine complement to the Romanian deadlift rather than a substitute — one loads the hip through a long range with the back working hard, the other loads it at the top with the back doing nothing.

On the "best glute exercise" claim: hip thrusts are frequently ranked above squats on the strength of surface electromyography comparisons. As the gluteus maximus record sets out, EMG measures electrical activity over a short window rather than what changes over months, and the ranking question is not settled. Both load it well.

The glute bridge is the same movement on the floor, needing nothing.
