Beginner's guide
§ 03 · GuideStrengthens your lower back and improves core support. It helps with heavy lifts and everyday bending and lifting.
You should feel it in your lower back and a bit in your glutes. It should not feel like neck strain or a pinch in your lower back.
A common mistake is overextending or driving the movement with the hips. Brace your core and stop when your torso is straight.
Back extension: variations and what they target
In the back extension you extend the hips and back with the torso tilted forward. The variations differ in the equipment and whether the lift emphasises the lower back or the glutes.
Lever Back ExtensionOn the back extension machine you sit and push the backrest backward. The load comes from a stack, and you can add it in small steps.
45 degrees Back Extension Scapula AdductionOn a 45-degree back extension bench your feet are supported and you lower your upper body from the hips. Squeezing the shoulder blades together at the top also strengthens the upper back.
Incline Reverse HyperextensionThe reverse hyperextension, where your upper body is supported and the legs rise behind you. It emphasises the glutes and hamstrings, and the lower back load stays light.
Sets and reps by goal
These are the numbers SisuLift uses when it programs this exercise. Sets come from the app's program templates and reps from the range inside which the app increases the weight.
| Goal | Sets | Reps | Effort | Rest |
|---|---|---|---|---|
| Strength | 2–3 | 8–12 | RPE 8–9 | 1.5 min |
| Muscle growth | 3 | 10–15 | RPE 7–8 | 1.5 min |
| General fitness and fat loss | 3 | 10–15 | RPE 7–8 | 1.5 min |
RPE describes how hard a set is on a scale of 1–10. RPE 8 means you would still have about two reps left.
When every set reaches the top of the range, SisuLift raises the weight by one equipment step next time and the reps drop back to the bottom of the range. In a calorie deficit the range stays the same, because that is when you want to keep your loads.
Back extension in your program
The back extension fits the end of a leg or back day after the heavy lifts. If you deadlift on the same day, keep back extensions light so your lower back does not get too fatigued.
Two to four direct sets a week is often enough for the lower back, because it also works in deadlifts, squats and rows. Done glute-focused, the lift also complements glute training.
Frequently asked
What is a back extension bench?
A back extension bench, or Roman chair, is a bench where your hips rest on a pad and your ankles are supported. It is used for back extensions, either horizontal or at a 45-degree angle. You can also use it for side bends and reverse hyperextensions.
What muscles does the back extension work?
The spinal erectors, the gluteus maximus and the hamstrings. When you keep your back straight and move from the hips, the glutes and hamstrings do more. When you round your back down under control and extend it one vertebra at a time, the lower back does more.
How do you make back extensions target the glutes?
Set the pad below your hips, turn your toes slightly out and round your upper back a little. Extend from the hips and squeeze your glutes at the top, but do not arch your lower back. Then the glutes do most of the work.
Should you add weight to back extensions?
Yes, once 15–20 reps feel easy. Hold a plate or dumbbell against your chest. A weight held behind the head adds more load. On the machine you can adjust the load in small steps.
Are back extensions okay with lower back pain?
Many benefit from strengthening the lower back, but the cause of the pain matters. Start without added weight and with a small range of motion, and add more only when the movement feels good. If the pain radiates to your leg or gets worse, stop and see a physiotherapist.

Tips
§ 05 · TipsKeep the movement focused on spinal extension rather than tilting your hips so the load stays on your back. Avoid hyperextension and keep your ribs down throughout the entire set.
The lever back extension provides stable loading and helps target the lower back through a controlled range of motion.
