What the hyperextension trains
Tap a muscle to see just that one and what it does in the lift.
Before the first rep
How to set up
- 01
Set the pad height. Adjust the pad so its top edge sits just below the crease of your hips, on your upper thighs. Your hips need to be free to bend over the edge.
- 02
Lock in your feet. Step onto the footplate and hook your heels under the rollers. Feet about hip width, legs straight with a soft knee.
- 03
Find a straight line. Start with your body in one line from head to heels. Tuck your chin slightly so your neck stays in line with your back.
- 04
Place your arms. Cross your arms over your chest to start. Hands behind your head is harder; holding a plate to your chest is harder still.
Step by step
How to do the hyperextension
- 01
Brace. Take a breath and tighten your stomach lightly, like bracing for a small push. Keep your ribs down.
- 02
Hinge down. Bend at the hips and lower your torso toward the floor under control, keeping your back long and flat. Go until you feel a stretch in your hamstrings or your back starts to round.
- 03
Pause at the bottom. Stop briefly at the bottom. Do not bounce or let your shoulders drop and round.
- 04
Rise. Squeeze your glutes and drive your hips into the pad to lift your torso back up, moving at the hips, not by bending your lower back.
- 05
Stop at straight. Finish when your body is in a straight line from head to heels. Do not lean back or arch past it, then start the next rep.
Cues to say in your head
- Hinge at the hips
- Long spine, chin tucked
- Hips into the pad
- Squeeze glutes to rise
- Stop at straight
- Slow on the way down
Fix these first
Common mistakes
Arching past straight at the top
Finish when your body is in one line. Leaning back past it squeezes the lower back without adding useful work.
Pad set too high
Move it down so it sits below your hip crease. If the pad is on your stomach, your hips cannot bend and your lower back does all the work.
Swinging up with momentum
Lower for about two seconds and pause at the bottom. If you need a bounce to come up, take the weight away.
Rounding the upper back and craning the neck
Keep your chest open and your chin slightly tucked. Look at the floor a little ahead of the bench, not up at the mirror.
Adding weight too soon
Own 15 slow bodyweight reps first, then hold a light plate to your chest and build up from there.
Stay safe
Start with bodyweight and a range you control, and add a plate only once every rep looks the same. Failing a rep is simple here: if you cannot rise, lower to the bottom, set any plate on the floor, then push yourself up with your hands on the frame or handles and step off the footplate. Keep loaded sets a rep or two short of failure, since form tends to slip into a swing or an arch first. Stop if you feel sharp pain, pain that runs down a leg, or numbness, and see a doctor or physical therapist before training through it.
Programming
Sets, reps and how much weight
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Muscle | 3 to 4 | 10 to 15 | 60–72% 1RM | 1 to 2 min |
| Strength | 3 to 4 | 6 to 10 | 72–82% 1RM | 2 to 3 min |
| Endurance | 2 to 3 | 15 to 25 | 40–55% 1RM | 45 to 90 sec |
| Technique | 2 to 3 | 10 to 12 | 40–55% 1RM | 1 min |
Plan your next session
Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.
Estimated 1RM 216 lb
Strength sets
155–177lb
3 to 4 sets of 6 to 10 reps, 2 to 3 min rest. For lifters who already handle a loaded hyper well. Keep the reps strict; this is a support lift, not a max effort lift.
Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.
Questions
Hyperextension questions
What muscles does a back extension work?
Mainly the spinal erectors in your lower back, plus the glutes and hamstrings that extend your hips. Your adductors help from the bottom, and your abs and upper back keep you in a straight line.
What is a 45 degree back extension?
It is the angled hyperextension bench most gyms have, set at 45 degrees so you work from a forward lean instead of lying flat. Because your body finishes on an incline rather than level with the floor, the top of the rep tends to feel easier than on a horizontal bench, which makes it a good place for beginners to start.
What is the difference between a back extension and a reverse hyperextension?
In a back extension your legs are fixed and your torso moves; in a reverse hyperextension your torso is fixed on a pad and your legs swing up behind you. Both train hip extension and the lower back, so use whichever your gym has.
Does the superman exercise work?
Yes, as a bodyweight option for the lower back and glutes. The range is small, so it is best for beginners, warm ups or home workouts; move to a back extension bench when it gets easy.
Should I go past straight at the top?
No. Stop when your body forms a straight line. Arching back past it, the hyperextension the name suggests, tends to add pressure on the lower back without training the muscles any better.
How many sets and reps of back extensions should I do?
Most people do 3 sets of 10 to 15, starting with bodyweight. Once 15 slow reps feel easy, hold a plate to your chest and work back up in reps.
