Lying Back Extension with Press
The Lying Back Extension with Press is a compound movement that trains the lower back with help from glutes and hamstrings. This guide covers the setup, the execution, the mistakes worth fixing early, and how to program it.
Driving the hips into extension against resistance is the most direct way to load the lower back. Unlike a squat, peak tension lands at the top — where the glutes are shortest and best able to produce force — which is what makes it such an efficient glute builder.
Who it is for. Anyone training glutes or hip power, from beginner to advanced. It sits well mid-session, after your main squat or hinge.
Muscles worked
The prime mover here is the lower back, with glutes and hamstrings assisting — which is why this movement earns its place as more than a single-muscle exercise.

How to do it
- Set your upper back against a bench or the floor so your shoulders can pivot freely, and place your bodyweight across your hips.
- Plant your feet flat, about shoulder-width, close enough that your shins finish vertical at the top of the rep.
- Tuck your ribs down and your chin slightly in, so your lower back stays neutral instead of arching.
- Drive through your heels and push your hips straight up until your torso and thighs form a straight line.
- Squeeze the lower back hard at the top and hold for a beat — this is the whole point of the movement.
- Lower under control until just before the load touches down, then go straight into the next rep.
Breathing. Breathe in on the way down, brace, and breathe out as you lock the hips out at the top.
Form cues that matter
- Finish with the hips, not the lower back — ribs stay down.
- Shins vertical at lockout; move your feet if they are not.
- Pause at the top of every rep, not just the first.
- Arching the lower back to reach "full" extension
- Feet placed too far out, so the hamstrings take over
Common mistakes
| The mistake | Do this instead |
|---|---|
| Arching the lower back to reach "full" extension | Keep your ribs pulled down and stop at a straight line from knee to shoulder. |
| Feet placed too far out, so the hamstrings take over | Walk your feet in until your shins are vertical at the top. |
| Bouncing off the bottom | Control the descent and pause an inch off the floor before driving back up. |
What makes this variation different
The Lying Back Extension with Press is a specific version of this movement, and the details in its name change how it should be performed.
- Using only your bodyweight means you can train anywhere, and it keeps the whole body involved in stabilising the movement. Progress comes from leverage, range and reps rather than from adding plates.
- Lying down gives the torso full support, which takes balance out of the movement and lets you focus everything on the working muscle. Keep your back in contact with the surface throughout.
