How high should the step be?

A low step of roughly 6 to 12 inches suits most people, and it should sit well below the bench so the hips can still drop below the level of your foot without touching the floor. Going higher adds little once the hips already hang clear, and it makes the front of the hip more likely to pinch at the bottom.

Why do my hamstrings cramp instead of my glutes working?

Almost always because the step is too far from the bench, so the working leg finishes nearly straight and the hamstrings do the extending. In single-leg bridges on the floor, moving the foot in toward the hips so the knee bent further cut hamstring activity from about 75 to about 23 percent of a maximal contraction while gluteal activity stayed about the same, and walking the step in a few inches is the same adjustment here.

How is this different from the two-leg feet-elevated version?

In Bodyweight Feet-Elevated Hip Thrust both feet are on the step, so two hips share the work and the rep count can go high. Here one leg carries all of it and also has to stop the pelvis dropping toward the free side, which is a different demand as well as a harder one.

Is this harder than the version with the foot on the floor?

Yes. Bodyweight Single-Leg Hip Thrust starts with the hips higher and gives the glute less range to control, so it is the beginner step and this is the one that follows it. Move on when you can hold the pelvis level for three sets of 15 on the floor version.

What should I do with the free leg?

Hold it in the air clear of the step with the knee relaxed, and leave it there for the whole set. It should not tap the step between reps or swing to help the hips up, because both hide how much the working glute is doing.

How many sets and reps should I do per leg?

Two to three sets of 8 to 15 reps per leg suits most people, with a pause at the top rather than a rushed turnaround. Do the weaker side first and match its number on the stronger side, so the gap closes instead of widening.

Bodyweight Feet-Elevated Single-Leg Hip Thrust

What Is the Bodyweight Feet-Elevated Single-Leg Hip Thrust?

Bodyweight Feet-Elevated Single-Leg Hip Thrust is a compound exercise that primarily targets the glutes and also engages the hamstrings, adductors and core. It is an intermediate-level movement performed with the upper back against a flat bench and the working foot up on a low step, so one leg drives the hips through a deeper range than the same movement done with the foot on the floor.

Raising the working foot changes where the rep begins, not where it ends. With the foot on a step the hips can sink below the level of that foot at the bottom, which puts the hip into more flexion and loads the glute before the first degree of extension happens. The top of the rep is unchanged: torso and working thigh in a straight line, and no higher than that. Starting deeper is a strong position rather than a weak one, since testing the isometric hip thrust at four hip angles in active men found that more hip flexion produced higher peak extension force and more gluteus maximus activity, with less biceps femoris activity.

That extra range is what this variation is for, and it is also what moves it past beginner level. Holding the pelvis level on one leg is already the hard part of any single-leg thrust, and the elevated foot hands the working glute a stretch of range to control before the hips even reach the height they would have started from on the floor. There is no competition or testing role here. It is accessory glute work, usually placed after the main lift of a lower-body session, in a warm-up before squatting, hinging or sprinting, or as the step between bodyweight and loaded single-leg hip extension.

How far the step sits from the bench steers the work more than how high it is. Set close, so the knee stays clearly bent at the top, the glute does most of the extending. Set far, so the leg finishes nearly straight, the hamstrings take a larger share and the set tends to end in a cramp rather than a glute burn. That trade-off bites harder here than with the foot on the floor, because the step fixes the foot above the ground and distance is the main thing left to tune.

Build up to this with Bodyweight Single-Leg Hip Thrust on the floor first, and with Glute Bridge or Bodyweight Hip Thrust before that if one leg is still too much. Bodyweight Feet-Elevated Hip Thrust is the same setup on two legs and is the sensible place to learn the deeper range. Once body weight stops being hard on one leg, add load rather than reps through Dumbbell Single-Leg Hip Thrust, Machine Single-Leg Hip Thrust or Barbell Single-Leg Hip Thrust.

Instructions

Set a low step or box on the floor in front of a flat bench, far enough away that the working knee will still be clearly bent at the top of the rep and close enough that the leg is not reaching.
Sit on the floor with your upper back against the long edge of the bench, so the edge of the pad crosses your back just below the shoulder blades.
Place one foot flat on top of the step, roughly in line with that hip. Start with your weaker leg.
Lift the other leg clear of the step and hold it in the air with the knee relaxed. It stays there for the whole set.
Rest your arms along the top of the bench for balance, but keep your weight off them.
Brace your abs and keep your head in line with your torso so the ribs stay down and the lower back stays neutral.
Let the hips hang in the start position, below the level of the step and just clear of the floor.
Drive through the heel and midfoot of the planted foot and lift the hips until your torso and working thigh form a straight line.
Stop there, with both hip bones at the same height, and squeeze the glute for a moment.
Lower under control until the hips are back below the level of the step, without resting them on the floor, then finish all your reps on that side before switching legs and matching that number.

Common Mistakes

Setting the step too far from the bench
Placing the step so far away that the working leg finishes nearly straight, which hands the extension to the hamstrings and is the usual cause of a mid-set cramp.
Stopping the descent at step height
Lowering only until the hips are level with the step instead of below it, which gives up the extra range that elevating the foot was meant to add.
Finishing with the lower back
Arching the lumbar spine to push the hips higher once the glute has run out, instead of stopping when the torso and working thigh form a straight line.
Letting the pelvis drop toward the free leg
Allowing one hip bone to sit lower than the other at the top, which takes the side-to-side control work away from the gluteus medius on the working side.
Pushing through the arms
Pressing down into the bench with the hands or elbows to help the hips up, which hides how much the single leg is actually doing.
Using a step that slides or tips
Driving one leg into a light step or an unsecured box, which can shift underfoot at the bottom of the rep where the hip is most flexed.

Injuries

Bodyweight Feet-Elevated Single-Leg Hip Thrust is a low risk exercise when performed with proper technique. There is no external load, the torso is supported on the bench for the whole rep, and a set that fails simply ends with the hips back down near the floor. What risk there is comes from the deeper start position and from the equipment rather than from the weight.

Hamstring cramping is the signature complaint of this variation. It comes from a step set too far from the bench, which leaves the working leg nearly straight at lockout and hands the extending job to the hamstrings, and it usually arrives near the top of a rep and ends the set early. The lower back is the other one: when the glute runs out before the hips are level, it is easy to arch the lumbar spine to buy the last few degrees, which turns a glute exercise into a low-back exercise. The extra depth can also pinch at the front of the hip at the bottom, which gets more likely the taller the step is, and the bench edge can bruise the back over a long set.

Most of that is fixed in the setup. Walk the step in until the working knee stays clearly bent at the top, brace the abs before the first rep so the ribs stay down, and treat a straight line from shoulder to knee as the end of the rep rather than a checkpoint on the way to a higher one. Use a step or box that will not slide or tip under a one-legged drive, and a bench that sits solidly on the floor. If the front of the hip pinches at the bottom, drop to a lower step, and slow the tempo to around two seconds up and two seconds down.

If holding the pelvis level through the deeper range is not there yet, go back to Bodyweight Single-Leg Hip Thrust with the foot on the floor, or learn the range on two legs with Bodyweight Feet-Elevated Hip Thrust. When it becomes easy, progress with load through Dumbbell Single-Leg Hip Thrust or Landmine Single-Leg Hip Thrust. Stop the set if you feel sharp pain in the low back, the front of the hip or the knee, or pain that does not settle when you change the step distance, and see a clinician before loading the pattern if you are working around a current hamstring, hip or back problem.
