12 Best Lower Back Exercises for Bodybuilding

The rack pull is a deadlift variant exercising all of the erector spinae muscles, plus your lower, mid, and upper back.

Rack pulls require you to pull with a limited range of motion, with the barbell starting either above or just below the knee.

Because you're lifting from a higher starting position, maintaining a neutral spine throughout the lift is more manageable.

With this deadlift variant, you may raise a greater weight, which can adapt your body to lifting heavier weights to develop your strength along the posterior chain muscles.

How to perform: 

1. Place the barbell in the squat rack below or above the knees.
2. Take your usual deadlift posture and grip.
3. Hinge down and grasp the bar with an overhand shoulder-width grip, squeezing your armpits together as you draw up till lockout, finishing with the glutes.
4. Return to your starting position.
5. Repeat for the desired number of reps.

4. Single-leg Romanian Deadlift

"The Romanian deadlift is beneficial for back strength. Consider the bent-over row: you wouldn't perform it with 200kg, but you could execute a Romanian deadlift with that weight."

- David Kingsbury, Head Trainer at Opus Fitness

Every excellent workout should include a single-leg (or single-arm) movement.

Unilateral exercise helps discover, attack, and correct muscle strength or size imbalances.

Perform the single-leg Romanian deadlift to strengthen your lower back.

How to perform:

1. Hold a bar while standing straight and move the bulk of your body weight to one of your feet.
2. From here, gradually tilt into a hip hinge while lifting your non-working foot off the floor.
3. When you tip over, the non-working foot should be relatively straight and fall behind you.
4. Reverse the movement and stand up once you feel significant stretching in the muscle groups of your working leg.
5. Repeat for reps.

Back extensions are performed by flexing your lower lower back to drop and raise your torso while lying on a hyperextension bench or a back extension machine.

You may do this exercise using only your body weight or load the motion with a barbell, dumbbell, or weight plate.

Tempo training, which involves performing slow repetitions, can also stimulate muscular growth in your lower back.

How to perform:

1. Lay on a hyperextension bench, face down.
2. Ensure the upper thighs are flat on the broad pad, with enough space to bend at the waistline.
3. Cross your hands before you, keeping your body straight (or you can place them behind your head).
4. Begin to bend forward progressively at the midsection as far as possible while keeping your back flat.
5. Go forward without curving your back until you feel a good stretch in your hamstrings, and you can't go any farther without rounding the back.
6. Gently return your torso to the starting position without bending your back.
7. Repeat for the desired number of reps.

6. Single Arm Dumbbell Row

Like the barbell rows, this exercise generates a considerably fuller contraction across a broader range of motion.

This is also an excellent method to isolate and concentrate on each part of your back, relaxing one while working the other.

How to perform:

1. Kneel on a bench, using your free hand to support yourself.
2. Adjust your posture so that your body is parallel to the ground.
3. Let the dumbbell dangle from your outstretched arm.
4. Pull the weight to the chest, palms facing the body, and elbows firmly tucked in.
5. Release the load and slowly extend your arm.
6. The degree and intensity of this lower back exercise may vary depending on your body angle, grip, and weight.

The deadlift is an excellent variant for pulling strength, but it can be modified to emphasize the lower back even more.

Stiff-legged deadlifts exclude your legs almost entirely from the equation, allowing you to focus on strengthening your lower back.

Stiff-legged puts a lot of mechanical force on your lower back without needing super-heavy weights.

It also improves hamstring and hip flexibility and provides a broader range of motion.

How to perform: 

1. Set up as you would for a conventional deadlift, with your legs under the hips, back flat, and arms on the bar slightly outside your thighs.
2. Extend your legs before lifting to raise your hips till your body is parallel to the ground.
3. Do a deadlift from here. Slowly lower the weight from a standing posture, focusing on tipping over at the waistline.
4. Your hips should generally remain at the same level the entire time.

8. Stability Ball Reverse Hyperextension

If your gym does not have a glute hamstring raise (GHR) machine, the stability ball reverse hyperextension is a terrific alternative and a perfect regression if you cannot execute the GHR.

It still works in most of the same muscle groups, but with a twist.

Because the surface is inherently unstable, you must pay close attention to your form.

The range of motion and duration under stress should provide additional hypertrophy or endurance advantages.

How to perform: 

1. Put a stability ball on the weight bench, then sit on it with your stomach and hips slightly off it.
2. Take a tight grip on either side of the bench and lift your legs off the floor until your glutes are fully tensed.
3. Lower them slowly until your toes contact the ground.
4. Reset and repeat for reps.

Even if it appears simple, the bird dog is a fundamental exercise that is frequently misused.

When done correctly, the bird dog challenges your core — particularly your lower back — to balance your body while switching your opposite-side leg and arm.

Raising and dropping your leg and arm slowly while remaining stiff is an excellent approach to enhance spine stability.

Therefore, your lower back will be more capable of supporting higher weights.

How to perform:

1. Kneel on the ground in a six-point stance (knees, hands, and toes on the floor), with your knees under the hips and your hands precisely beneath your shoulders.
2. Throughout the exercise, keep your back in a neutral position.
3. Lift your opposite leg and arm straight out, maintaining a solid core and a horizontal line from head to toe.
4. Return to your starting position and complete all repetitions on one or both sides.

10. Jefferson Curl

If you want to strengthen and build your lower back, you'll need to become used to some lower back mobility under stress.

Spinal flexion, contrary to common assumption, is not inherently dangerous.

Most athletes aren't used to training in or out of lumbar flexion.

As a result, a workout like the Jefferson curl is effective in stimulating specific muscles.

You'll have to go slowly and prioritize solid form.

How to perform:

1. Begin by standing straight with an unloaded barbell or something lighter (such as a PVC pipe).
2. Start the Jefferson curl by curling your upper back over.
3. The bar or pipe should start to make its way down your thighs.
4. Continue curving your back until you feel a big stretch in the hamstrings or the barbell touches the floor.
5. From top to bottom, your spine must be flexed.
6. Resume to a standing posture by reversing the process, slowly and carefully unfurling your spine.
7. Repeat for reps.

Kettlebell swings are straightforward to master and perform and benefit a wide range of muscle groups.

In addition to enhancing the lower back muscles, it works the abs, glutes, pecs, and quads, making it a great all-around erector spinae exercise.

How to perform:

1. Choose your preferred weighted kettlebell.
2. Hold the kettlebell with both hands, slightly in front and between your legs. Set your feet shoulder-width apart.
3. Swing the kettlebell back between your feet to generate momentum, then forward and upward to shoulder width with your knees slightly bent.
4. Maintain a tiny bend in your feet as the bell rises while pressing your hips forward.
5. Let the kettlebell return to its starting position.
6. Repeat for the desired number of reps.

12. Superman

The superman is an excellent bodyweight exercise for preventing low back problems, improving posture, and developing a more vital mind-muscle link to your glutes and lower back.

The erector spinae is trained as an extensor by letting you lift your arms and legs off the ground while flexing the lower back and retaining this position.

Your lower back ought to work hard to commence the motion and stabilize to maintain the top isometric posture.

This is a lower back isolation exercise that anybody can do.

How to perform:

1. Lie face down on a workout mat, forehead firmly on the floor, arms and legs extended.
2. Lift your feet and hands 4 - 5 inches off the ground while maintaining your tummy flat.
3. Maintain this lifted stance for three seconds before carefully lowering your feet and hands to the floor.
4. Repeat for the desired number of reps.

Your lower back comprises many essential muscle groups and five lumbar vertebrae (L1-L5) [1].

Knowing how they operate is critical for keeping your lower back healthy and robust so you can lift longer and stronger.

Here's a summary of the anatomical structure of the lower back.

The Erector Spinae Muscles

Three muscles constitute the erector spinae column.

The erector spinae goes from the lower back and hips to the cervical (neck) spine and is placed laterally and posteriorly to the spinal column.

The erector spinae are tenderloin-like muscles that run vertically alongside the spine [2].

The three muscles are:

• Spinalis: The spinalis muscle is the smallest and closest to the spinal column. Its tasks include rotating side to side and assisting with head control when looking up.
• Iliocostalis: The Iliocostalis is the most distant from the spine and originates at the sacrum. It enables spinal extension and lateral flexion.
• Longissimus dorsi: This is the middle and biggest of the muscles. Its functions include lateral extension and flexion of the spine and the ability to swivel your head in both directions.

Vertebrae

The lower back area has 5 vertebrae, denoted L1-L5.

The lumbar vertebrae form a lordotic curvature and have the most significant bodies in the spine.

Its bigger shape reflects the lumbar spine's role in supporting the upper body.

L1-L5 allows lateral flexion, extension, and flexion, but not rotation [3].

The erector muscles are located along the spine.

They contribute to spinal stability by maintaining the spine neutral under stress and preventing unwanted motion.

This is useful not only for deadlifting and squatting but also for sprinting, jumping, and bending down to pick up something.

"Your spine and back muscles sustain your upper and lower body; without them, it would be quite weak. A strong back will thus aid in supporting your body and allowing you to perform better and more effectively."

- Benjamin West, Co-founder of 360 Athletic

3. Improved Posture

Sturdy spinal erectors are essential for maintaining excellent posture and a neutral spine during strongly loaded motions.

You may reverse some of the effects of sitting by training them.

That is, as long as you maintain your consistency.

Performing lower back exercises early into the exercise makes sense if you want a strong spine.

There is, however, one significant limitation.

Because the lumbar spine is the primary support structure for practically every compound movement — from deadlifts to rows to the overhead press — you don't want to overwork it if you have other lifts to accomplish in the same session.

To build lower back strength, and for muscle growth, start with complex lifts that stress the muscles isometrically, then progress to isolation exercises for the lower back muscles along the posterior chain after the workout.

4. For Endurance

While other workouts frequently put your lower back to the test, improving endurance is simple.

Most compound lifts performed correctly will enhance your spine's capacity to maintain excellent posture for longer durations.

If you want to improve your lower back endurance, prioritize time under tension, typically seen in isometric workouts such as the bent-over row or plank.
