Smith machine hip thrust
The Smith machine hip thrust works your glutes, with your hamstrings and inner thighs helping. Start with 2 to 3 sets of 8 to 12 reps, stopping with about 3 reps in reserve. To build muscle, do 2 to 4 sets of 6 to 12 reps.

We film every move with real women. Until then, follow the steps and the 3 tips.
- Tip 1Bar over your hips, not your belly
- Tip 2Chin tucked, ribs down
- Tip 3Rotate the bar to unhook and rehook
Where you should feel it
In your glutes, mostly at the top. Your hamstrings help. If you feel it more in your lower back, stop lifting once your torso lines up with your thighs and keep your ribs down.
- Main muscles
- Gluteus maximus
- Also working
- Semitendinosus and semimembranosus, biceps femoris, adductor magnus, and gluteus medius
How to do it
Place the bench crosswise inside the Smith machine and sit on the floor with its edge just below your shoulder blades and the padded bar over your hips.
Set the safety stops at the lowest point of the movement and place your feet hip-width apart.
Lift your hips slightly and rotate the bar to unhook it, with both hands on the bar.
Drive through your heels until your torso lines up with your thighs and your shins are vertical, then squeeze your glutes for 1 second.
Lower under control until your hips almost touch the floor. At the end of the set, lift and rotate the bar back onto the hooks.
Common mistakes
Mistake
Bench in the wrong spot, so the bar comes down on your belly or thighs.
How to fix it
Before loading, lower the empty bar and see where it lands. Move the bench until it lands on your hips.
Mistake
Arching your lower back at the top to push the bar higher.
How to fix it
Stop when your torso lines up with your thighs. Keep your ribs down and look toward your knees at the top.
Mistake
Starting the set without setting the safety stops.
How to fix it
Set the stops before your first set. If you run out of strength mid-set, just lower your hips and let the bar rest on them.
Sets and reps for your goal
| Goal | Sets | Reps | Reps in reserve | Rest |
|---|---|---|---|---|
| Getting started | 2 to 3 | 8 to 12 | 3 | 60 to 120 s |
| Muscle and definition | 2 to 4 | 6 to 12 | 1 to 3 | 1.5 to 3 min |
| Max strength | 3 to 5 | 3 to 6 | 2 to 3 | 2.5 to 4 min |
Max strength (3 to 6 reps) only once your form is solid, always with 2 to 3 reps in reserve.
Reps in reserve: how many more reps you could still do with good form when you end the set.
Variations
Same movement, other equipment
Free barbell
The bar has no track, so you control its path. It takes a bit more practice to set up.
Machine
Fixed back pad and belt, no bar or bench to set up. The quickest one to adjust.
Dumbbell
One dumbbell on your hips and your shoulder blades on a bench. For lighter loads or when the Smith machine is taken.
At home or with more support
At home: couch hip thrust
Shoulder blades on the edge of a sturdy couch pushed against a wall, with a dumbbell or a weighted backpack on your hips, held with both hands.
Prefer more stability? Floor glute bridge
Prefer not to set up a bar or bench? In the bridge your back stays on the mat and you can rest a dumbbell on your hips.
Taken? Swap it for one of these
They work the same main muscle.
