The best lower back workout pairs a hip hinge with a direct back extension, then adds core work that keeps your spine from arching. Train it two or three times a week, mostly 10 to 20 reps stopped 1 to 3 reps short of failure, and add range, reps, then weight. Your squats, deadlifts and rows already work the lower back, so it needs fewer direct sets than your chest or arms.
Lifters who already squat, deadlift or row and want a lower back that holds position when the weight gets heavy.
Romanian deadlift training alone did not raise isolated lower back strength in trained men, while isolated lower back extension training raised it, so each session pairs a heavy hinge with a Weighted Back Extension that trains your lower back directly. That is 6 hinge sets and 6 back extension sets a week, fewer than the 10 to 20 your other muscles get, because your compound lifts already load your lower back. Pallof Presses and Dead Bugs train your trunk to resist twisting and arching under load.

Run Lower Back A and Lower Back B on separate days at the end of a leg or pull day. Keep at least one day between them and your heaviest deadlift session.
How to progress
Use double progression: when every set reaches the top of the rep range at the target RIR, add weight next session. On back extensions, hold a plate once you reach 15 reps on every set, then move up a plate size.
People training at home with a pair of dumbbells who want a stronger lower back without a gym.
Light dumbbells cap how heavy your hinges get, so the hinges and Supermans use 10 to 20 reps and take each set close to failure instead, which builds muscle across a wide range of loads. Supermans give your spinal erectors direct work with no equipment, and the Dumbbell Good Morning, with the weights at your shoulders, makes your back work harder at the same weight because your torso becomes a longer lever. Across the week that is 6 Superman sets, 4 good morning sets and 6 Romanian deadlift sets.
Do the same session twice a week, for example Monday and Thursday, either alone or after your usual home workout.
How to progress
Add reps until every set hits the top of the range, then slow the lowering to three seconds before moving to heavier dumbbells. On Supermans, lengthen the hold at the top from one to three seconds once you reach 20 reps.
Lifters whose lower back gives out before their legs in squats, deadlifts or rows, or who feel it tire through a long day at a desk.
When your back quits before your legs and hips, it needs more endurance, not a heavier max, so this plan trains them often with moderate reps and more reps in reserve instead of heavy sets. The Cable Pull-Through lets you hinge with your hips doing the work while your back holds still, and the Exercise Ball Back Extension trains the erectors through a range you can grow week by week. Three short sessions give you 9 back extension sets and 9 pull-through sets a week.
Do this session three times a week on non-consecutive days, after your main lifts or on its own. Keep it short so it adds to your training instead of competing with it.
How to progress
Grow the range first: lower a little further on each back extension as long as you rise smoothly. Then add reps to the top of the range, then weight, and once the ball feels easy move to the Weighted Back Extension.
Use one heavy hinge and one back extension in the same session. The Romanian Deadlift or Good Morning loads your hamstrings and glutes with your back holding position, and the Weighted Back Extension makes your spinal erectors move the weight themselves. Hold a plate to your chest once you clear 15 clean reps, and keep barbell hinges at 6 to 12 reps so your grip and hamstrings are not the limit.
With one pair of dumbbells you can hinge, extend and brace. Do the Dumbbell Romanian Deadlift and Dumbbell Good Morning for 10 to 15 reps, then Supermans for 12 to 20 with a one-second hold at the top. When the dumbbells feel light, slow the lowering to three seconds before you buy heavier ones.
The hinge you can load heaviest, so it teaches your back to hold a flat position under real weight while your hamstrings and glutes move it.
How to do it
Deadlift the bar from the floor or take it from a rack at mid-thigh, hands just outside your legs.
Unlock your knees slightly and push your hips back, sliding the bar down your thighs.
Lower until your hips stop moving back, usually just past your knees, with your back flat.
Drive your hips forward to stand tall without leaning back at the top.
Cues
Bar stays on your legs
Hips back, not chest down
Stop where your hips stop
Common mistakes
Chasing the floor by rounding your back. End the rep where your hips stop traveling back.
Letting the bar drift forward. Keep it close enough to brush your thighs.

Direct lower back, loaded
Weighted Back Extension
Lower Back
Your spinal erectors move the weight themselves instead of only holding position, which is the work a hinge leaves out. The demo shows it on a hyperextension bench while holding a weight.
How to do it
Set the pad just below your hip crease so your hips can fold over it.
Lock your heels under the rollers and hold a plate against your chest.
Lower your torso until you feel a stretch in your lower back and hamstrings.
Rise until your body forms a straight line from head to heels, then lower under control.
Cues
Straight line at the top
Plate pinned to your chest
Slow on the way down
Common mistakes
Swinging past straight into an arch. Stop when your body is in line.
Using a plate before you own bodyweight reps. Start without one and add it after 15 clean reps.

Heavy hinge, more back
Good Morning
Hamstrings, Glutes
With the bar on your back, your torso is a longer lever than in a Romanian deadlift, so your lower back works harder at the same weight.
How to do it
Set a barbell across your upper back as you would for a squat and step back from the rack.
Stand with feet hip-width and knees slightly bent, and brace your trunk.
Push your hips back and let your chest lower until your torso is close to parallel or your hips stop moving back.
Drive your hips forward to stand back up.
Cues
Hips back first
Chest proud, back flat
Knees soft, not bending more
Common mistakes
Turning it into a squat by bending your knees as you go down. Keep the knee angle fixed.
Starting too heavy. Use well under your Romanian deadlift weight until the pattern is solid.

Anti-rotation core
Pallof Press
Abs
Your trunk has to stop the cable from twisting you, the same job it does when a heavy bar or one-sided load tries to pull you out of position.
How to do it
Set a cable handle at chest height and stand side-on to the machine, feet hip-width.
Hold the handle at your chest with both hands and step out until the cable pulls.
Press your hands straight out in front of your chest and hold for two seconds.
Bring them back to your chest without letting your hips or shoulders turn.
Cues
Square to the front
Ribs down
Press straight, not toward the machine
Common mistakes
Rotating toward the cable. Step closer or lower the weight until your torso stays square.
Rushing the hold. The two-second pause at full reach is the hard part.

The ball lets you lower only as far as you can rise from smoothly, so you can grow the range week by week. The demo shows it with feet braced against a wall and hands behind the head.
How to do it
Drape your hips over the ball, face down, and wedge the balls of your feet against a wall.
Rest your fingertips lightly at your ears.
Let your chest curl down around the ball as far as you can control.
Raise your chest until your shoulders, hips and ankles line up, then lower again.

Hinge with the back held still
Cable Pull-Through
Glutes, Hamstrings
The cable pulls from behind, so your hips do the work and your lower back only has to hold position. It trains the hinge without the heavy spinal loading of a barbell.
How to do it
Attach a rope to a low pulley and face away from the machine, holding the rope between your legs.
Walk out until the stack lifts and stand with feet a little wider than your hips.
Push your hips back with soft knees until you feel your hamstrings stretch.
Drive your hips forward to stand tall and squeeze your glutes at the top.
Cues
Hips drive, arms just hang
Back stays still
Stand tall, don't lean back
Common mistakes
Pulling with your arms. Let them hang like ropes.
Squatting down instead of hinging. Send your hips back, not down.

Make it fit you
Already deadlifting heavy
If you pull heavy once a week, drop the Romanian deadlift from Lower Back A and keep the back extensions. Your deadlift already covers the heavy hinge, and the extensions are the part it leaves out.
No hyperextension bench
Use the Exercise Ball Back Extension with your feet against a wall, or Supermans on the floor. Keep the same sets and rep range and slow each rep down to make up for the lighter load.
Grow range before load
On back extensions, add range before you add weight. Lower a little further each week while you can still rise smoothly, and only add a plate once the full range feels solid for 15 reps.
Keep RIR honest on hinges
Stop hinge sets 2 reps short of failure. When your back starts to round or your hips shoot up, that set is over, even if you could grind out another rep.
Track it with your main lifts
Log RIR on every set so you can see when your back extensions get easier at the same weight. In RIRLift, weekly hard sets per muscle show how much lower back work your squats, deadlifts and rows already give you.
Questions
How do I build muscle in my lower back?
Train it directly with back extensions or Supermans, mostly 10 to 20 reps stopped 1 to 3 reps short of failure, and add a heavy hinge like the Romanian deadlift. Add range, then reps, then weight. Two or three sessions a week is plenty, since your other lifts already work it.
What are the big 3 exercises for lower back?
The big 3 usually means Stuart McGill's curl-up, side plank and bird dog, which train your trunk to hold still. They build endurance, not much muscle. For a stronger lower back, pair that kind of bracing work with loaded back extensions and hinges, as the plans here do.
Are back extensions good for your lower back?
Yes. They are one of the few exercises where your spinal erectors move the load instead of only holding it. Rise to a straight line from head to heels and stop there rather than arching past it.
How do I get a toned lower back?
Build the muscle with the training above and manage your body fat with your diet. Exercise alone will not remove fat from one spot, so the muscle shows once your overall body fat drops.
How often should you train your lower back?
Two or three times a week works well. Your squats, deadlifts and rows add to it, so keep direct lower back work to a few sets per session and spread it out rather than piling it into one day.
