How to do it
Lying face down with your hips at the edge of the bench, raise your legs up to horizontal. Extends the hip with little compression on the spine, unlike the classic back extension.
Muscles worked
Main muscle: lower back. Also worked: glutes. When it plans weekly volume, the generator counts each set of this exercise as one full set for lower back and half a set for each secondary muscle (what is known as fractional counting).
Reverse hyper on bench vs. the 45° back extension machine: what actually changes
The difference is which end of the body moves. On the 45° back extension machine your legs are locked in place and the torso rises and falls, so the lower back spends most of its effort holding the spine in position. In the reverse hyper on bench your torso rests on the pad and the legs swing through the arc: the work lands on hip extension, with the glutes and hamstrings doing the lifting and the spinal erectors just stabilizing. Compared with back extensions or good mornings, spinal loading is lower because nothing is sitting on your back.
Pick it if hinging under load leaves you feeling it mostly in your lower back, if you want extra glute work after a heavy squat or deadlift day, or if you have a sturdy bench at home but no 45° machine. It fits at the end of a session, for 2-4 sets of 10-20 controlled reps.
The classic mistake here is swinging. With no counterweight, it is easy to fling the legs up on momentum. Lift for a slow count of two, pause briefly at the top and lower even more slowly. To progress, squeeze a light dumbbell between your feet or use ankle weights before you chase more reps. If low back pain shows up, shorten the range, drop the load and check in with a professional.
Technical sheet
- Movement pattern
- Hip hinge
- Minimum level
- Intermediate
- Technical demand
- Needs coaching
- Fatigue it generates
- Moderate (1 out of 2.2)
- Risk if technique breaks down
- Low
These are the values the generator uses to decide where the exercise goes within the session.
Recommended sets and reps
As a compound lift, it fits in 3–5 sets of 5–12 reps leaving 1–3 reps in reserve (RIR). Prioritize it at the start of the session, when you're fresh.
Common mistakes to avoid
- Hyperextending the lower back at the top of the movement instead of finishing in a neutral position.
- Not adjusting the seat and pads to your body: your joint should line up with the machine's pivot.
- Using too much weight at the cost of technique and full range of motion.
What the research says
This is a multi-joint lift, and with these the rep range matters less than it seems: Schoenfeld and colleagues (2021) concluded that muscle growth is similar with heavy or moderate loads as long as sets end close to failure, while maximal strength improves more with heavy loads.
On how hard to push: the meta-analysis by Refalo and colleagues (2023) found no clear advantage in going to failure over stopping just short of it. That is why the generator programs it with reps in reserve (RIR) instead of asking for failure on every set.

How Reverse hyper on bench compares with other lower back exercises
Of the 6 lower back exercises in the catalogue, ranked from least to most fatiguing by the values the generator uses, Reverse hyper on bench is number 5.
It sits in the middle of its group: it works as the day's main exercise or as a second or third one.
With different equipment, the same movement pattern offers 2 alternatives, such as Back extensions and Good mornings.
| Exercise | Equipment | Fatigue | Technique |
|---|---|---|---|
| Back extensions | bodyweight | Moderate (0.8 out of 2.2) | Basic |
| 45° back extension machine | machine | Moderate (0.9 out of 2.2) | Basic |
| Reverse hyper on bench | machine | Moderate (1 out of 2.2) | Needs coaching |
| Good mornings | barbell | High (1.6 out of 2.2) | Advanced |
On a machine. In the meta-analysis by Haugen et al. (2023), with thirteen studies and 1,016 participants, there were no significant differences in muscle growth between training on machines and with free weights.

Frequently asked questions
What muscles does Reverse hyper on bench work?
Reverse hyper on bench mainly works the lower back muscle group, plus synergist and stabilizer muscles depending on the variation.
How many sets of Reverse hyper on bench should I do?
Between 3 and 5 sets per session, adjusting the total weekly volume for lower back to your level (about 10–20 sets per muscle per week).
Can I do the reverse hyper on a bench if I don't have a counterweighted machine?
Yes, a sturdy bench is enough to learn the movement. Lie face down with your hips past the edge, hold the bench with your hands and raise your legs to horizontal, no higher. To add load, use ankle weights or a light dumbbell between your feet. Make sure the bench cannot slide, and avoid throwing your legs up with momentum.
