The prone hip extension is a bodyweight glute exercise performed face down on the floor or a bench, lifting one straight leg behind you with the hip as the only moving joint. Lying flat means gravity resists the leg through a short arc above the line of your body, so the load is small and the range ends where your pelvis starts to tip. That makes it a control drill rather than a strength lift: one leg at a time, with the lower back held still. Coaches use it to warm up the glutes before hinging or squatting.
What Muscles Does the Prone Hip Extension Work?
- Primary: gluteus maximus
- Secondary: hamstrings (biceps femoris, semitendinosus), adductor magnus
- Tertiary: erector spinae, transversus abdominis, gluteus medius (side glute)
How Do You Set Up for the Prone Hip Extension?
Lie face down on a mat with your legs straight and together, toes pointed at the floor. Rest your forehead on your stacked hands, or lie across a flat bench with your hip bones on the pad. Press your pubic bone into the surface and draw your ribs down so your lower back flattens slightly. Squeeze both glutes to take the slack out of the hips. Hold that pelvic position before the first leg moves.
How Do You Perform the Prone Hip Extension?
- Brace your abs and keep both hip bones pressed evenly into the surface.
- Squeeze one glute and lift that leg, knee locked and toes pointing down.
- Stop when your thigh clears the surface and you feel the pelvis begin to tilt, usually a hand's width up.
- Hold the top for two counts, glute tight and the opposite hip still flat.
- Lower the leg over three counts until the toes touch without the glute releasing.
- Reset flat with both legs together, ready to lift the same leg or switch sides.
What Are the Key Form Cues?
- Start the lift with the glute, not the heel: squeeze the cheek first and let the leg follow so the hamstring does not take over.
- Keep both hip bones on the surface: the moment one lifts, the range you gain is coming from your lumbar spine.
- Keep the knee straight through the whole arc; a bent knee shortens the lever and hides the loss of range.
- Press your forehead lightly into your hands so the neck and shoulders stay relaxed.
- Feel the top position as a squeeze you hold, not a height you reach.
What Are the Most Common Mistakes?
- Lifting the leg too high: past the point where the pelvis tips, the movement becomes lumbar extension and the low back does the work the glute should, so stop at the tilt.
- Rotating the hip out to gain height: the toes turn outward and the range comes from the hip socket rather than extension, so keep the toes pointing down.
- Bending the knee on the way up: the hamstring shortens and the glute contribution drops, so lock the leg.
- Rushing the reps: the arc is short, so a fast tempo leaves almost no time under tension; hold the top and lower slowly.
- Letting the abs go slack: the ribs flare, the lower back arches and the pelvis rocks with every rep, so brace before you lift.
What Are the Best Prone Hip Extension Variations?
- Bent-knee prone hip extension: knee at 90 degrees, a shorter lever that isolates the glute for beginners.
- Prone hip extension on a bench: hips on the pad and legs hanging, giving a longer arc from below the body.
- Double-leg prone hip extension: both legs lift together, doubling the demand on the lower back.
- Ankle-weighted prone hip extension: a light cuff on the ankle adds resistance at the top.
- Stability ball reverse hip extension: the same pattern draped over a ball, with the added demand of a rolling base.
How Do You Progress the Prone Hip Extension?
- Progress by leverage first, straightening the knee fully, then add a 2 to 5 pound ankle weight.
- Build from 10 to 20 reps per leg before adding any load.
- Take the work from two sets to four per leg.
- Extend the top hold from two counts to five, then move to the bench version for extra range.
How Should You Program the Prone Hip Extension?
Use it as a glute warm-up before squats, hinges or lunges, or as a light finisher at the end of a lower body day. It handles frequent work, so three or four sessions a week, for 2 to 4 sets of 10 to 20 reps per leg with 30 to 45 seconds of rest. Pair it with a loaded hinge such as a Romanian deadlift, which trains the same hip extension against real weight.
