Ejercicios para la espalda baja: los 8 mejores, paso a paso

Lower back exercises: the 8 best, step by step

Does your lower back hurt, yet you still think everything can be fixed just by “resting more”? That’s usually where things go wrong. Many people separate exercise from sleep, as if they were two different worlds, when in fact your lower back responds to the whole picture: how you move, how you get up, and what surface you spend the night on.

The good news is that you don’t need to start with a complicated routine. You can activate your lower back muscles and core with simple movements, even upon waking up, using a stable and comfortable surface.

In this list, you’ll find a practical selection of the best lower back exercises, with an unusual but highly useful focus: the relationship between movement and your mattress. Because a good mattress doesn’t just influence how you sleep. It can also give you a safe foundation to start the day with less stiffness and more body control.

1. Dead Bug

If you find it difficult to move your arms and legs without your lower back “pulling,” the dead bug is often a great entry point. It’s done lying on your back and seems simple, but it teaches something key: moving your limbs without losing the neutral position of your spine.

That makes it especially useful in the morning, when you feel stiff in the back as you get out of bed. Instead of getting up abruptly, you can take a few minutes to activate your deep core, pelvis, and breathing control on a stable surface.

How to do it properly on the mattress

Lie on your back with your knees raised and bent. Reach your arms toward the ceiling. From there, slowly extend one leg and the opposite arm, without allowing your lower back to arch.

The most important rule is simple: gently press your lower back against the surface. If the mattress gives away too much, you’ll lose your reference point. That’s why a base with ergonomic support and balanced firmness makes exercising easier than a soft surface.

Practical rule: if you notice your back lifting when you lower your leg, reduce the range of motion before continuing.

A very common real-life example is someone who spends many hours sitting and gets up feeling “locked.” In that case, the dead bug helps you start the day with control, not tension. It also fits well into gentle routines for returning to movement.

  • Start easy: do slow repetitions on each side, without trying to go fast.
  • Prioritize control: exhale as you extend, inhale as you return.
  • Use the surface to your advantage: a mattress with even support, such as a medium-firm hybrid, helps you notice if your pelvis is moving.

If you also want to improve your nighttime posture so that your morning work isn’t lost, this guide to sleeping with lower back pain pairs very well with this exercise. The idea isn’t just to do more. It’s to do it better, from the very first minute of the day.

2. Bird Dog

The bird dog has a clear advantage. It forces you to stabilize while you move. And that’s the ability your lower back needs in real life, not just in an exercise routine.

Think about everyday actions like bending down to pick up a backpack, turning to reach something, or lifting a child into the car. If your torso doesn’t know how to maintain stability while your arms and legs move, your lower back compensates.

Stability you can feel outside of training

Get on all fours, with your hands under your shoulders and knees under your hips. Activate your core before moving. Then extend one arm forward and the opposite leg back, without rotating your pelvis.

The most common mistake is lifting the leg too high and arching your back. There’s no need. The important thing is to maintain a long line from your hand to your heel, as if someone were pulling you in two opposite directions.

When the bird dog is done properly, it doesn’t look particularly spectacular. It looks stable.

This nuance matters a lot at home. On a firm mat or a medium-firm mattress, the exercise can be done comfortably, but without losing the sensation of support. If the surface sinks too much, your body starts looking for balance where it shouldn’t.

When it fits best

It works very well as a transitional exercise between gentle mobility and strength work. If you’re coming from a sedentary phase, it teaches you to distribute the load between your core, glutes, and lower back instead of putting it all on your lumbar area.

  • Before extending: contract your core as if you were about to receive a light tap on your belly.
  • While holding: aim for a few seconds of control, not a forced posture.
  • When returning: lower yourself gently. The return also provides training.

Among the best lower back exercises, this one stands out because it combines coordination, control, and balance. It doesn’t impress with intensity. It impresses with how well it prepares your back for everyday life.

3. Bridge

The glute bridge corrects a very common problem. Many people try to protect their lower back by strengthening only their back, when in fact they need their glutes and pelvis to work together better.

This is where the bridge earns its value. It’s one of the most accessible movements to start waking up the posterior chain without the need for equipment and with a high sense of safety, especially in the morning.

A basic exercise with clinical backing

The American Academy of Orthopaedic Surgeons (AAOS) includes the bridge in its exercise program to strengthen the lower back. It’s one of the most frequently recommended basic exercises in physical therapy guidelines.

Lie on your back with your knees bent and feet flat. From there, push through your heels and lift your pelvis until your torso and thighs are aligned without exaggerating the lumbar arch.

Many people notice at first that they push with their back instead of their glutes. If this happens to you, try thinking about “closing” your buttocks at the top and keeping your pelvis stable for a moment before lowering.

What changes when you do it on a good surface

A mattress with consistent lumbar support can help you start the movement with more confidence. It doesn’t replace proper technique, but it does give you a less aggressive foundation at dawn, when stiffness is still present. Morfeo’s Altus mattress, with medium-firm firmness and over 2,000 pocketed coils, is designed precisely for that combination of support and comfort.

  • Position your feet properly: hip-width apart.
  • Push through your heels: this better activates your glutes and posterior chain.
  • Avoid momentum: go up and down with control.

If you’re considering changing the surface you sleep on because you get up with a strained back, this guide on mattresses for back pain helps you understand what to look for. In many cases, improving your bridge and improving your rest go hand in hand.

4. Cat-Cow Stretch

Not everything in lumbar health is about strength. If you get up feeling “stiff” and notice that your pelvis and back are moving independently, you need controlled mobility. That’s where cat-cow works very well.

This movement alternates flexion and extension of the spine on all fours. Done without rushing, it restores a sense of rhythm to your back, which is very useful when you’ve spent hours motionless during the night.

How to use breathing to move better

In the cow phase, let your chest open gently and your pelvis tilt forward as you inhale. In the cat phase, round your back as you exhale, without pushing to the limit.

There’s no need to exaggerate the movement. The goal isn’t to go further, but to distribute the movement better throughout the spine so that the lower back doesn’t do all the work alone.

Sometimes lower back stiffness doesn’t need more strength. It needs you to start moving with order again.

A padded surface helps protect your wrists and knees. If you practice upon waking, a stable mattress can serve as a starting point, especially if the floor feels too harsh first thing in the morning.

When it suits you best

Cat-cow fits very well for people who spend a lot of time sitting or for those who get up with a feeling of compression. It also works well before other more demanding exercises, because it prepares the pelvis, core, and breathing.

  • Move slowly: each transition should feel fluid.
  • Don’t lock your neck: let it follow the movement.
  • Stay within a comfortable range: control is worth more than range of motion.

If you want to see how to integrate this mobility with other gentle movements for everyday life, this selection of exercises to relieve lower back pain can serve as a practical complement.

5. Superman Hold

The superman isn’t for every situation. But when used properly, it can strengthen the back’s extensor muscles in a very direct way. It’s a demanding exercise, so it should be approached with respect.

It’s done lying face down, slightly raising your arms, chest, and legs. The key is in that word: slightly. You don’t need to lift your body very high to generate useful work in the posterior chain.

Less height, more control

Many people turn this exercise into a struggle to lift higher. That approach usually strains the neck and compresses the lower back. The correct way is to think about lengthening your body, not arching it.

A clear example is someone who already controls the bridge, bird dog, and basic mobility and wants to add a more intense stimulus for their extensors and glutes. In that context, the superman can fit in as a brief complement, never as the first choice if there is active pain.

If you feel a sharp pain or a clear increase in lower back discomfort, skip this exercise today.

On a firm surface, you can better control the lift and the return. A hybrid mattress with good stability helps you notice if you’re lifting from your back or if you’re distributing the work between your glutes, core, and mid-back.

How to introduce it without overdoing it

Start with short holds and continuous breathing. Don’t hold your breath. That only adds tension.

  • Lift just a little: a few inches are enough.
  • Look down: this protects the back of your neck.
  • Rest between repetitions: quality comes first.

Among the best lower back exercises, this one holds a more advanced place. Use it when you already have a foundation and when your back tolerates extensions well. If you’re going through an episode of discomfort, it’s better to prioritize stability and control over intensity.

6. Pallof Press

The Pallof press demonstrates something important. The lower back doesn’t just suffer when you flex or extend. It also suffers when you cannot resist rotation.

That’s why this exercise, although it doesn’t seem “back-focused,” is very valuable. It works your ability to keep your torso stable while an elastic band tries to rotate you. That happens in daily life with bags, quick turns, or asymmetrical loads.

What it really trains

Place a band to one side of your body, hold it with both hands, and bring it to the center of your chest. From there, push your arms forward without letting your torso rotate. The sensation isn’t one of wide movement, but of internal resistance.

If you want to practice the pattern before using resistance, you can try the posture on your knees on a stable surface. That helps you understand the alignment of your ribs, pelvis, and core before adding external tension.

Below you have a visual demonstration of the movement:

Mistakes that strain your back without you realizing it

The most common mistake is sticking out your chest, arching your lower back, and confusing stiffness with stability. Useful stability comes from an active core and a relatively neutral pelvis, not from stiffening your entire back.

  • Start with low resistance: if the band pulls you around, you’re not training control.
  • Keep your knees soft: don’t lock your posture.
  • Exhale as you extend: that makes the core’s work easier.

This exercise works very well for people who perform rotational movements in their work or sport. Also for those who notice that their back gets irritated when carrying weight on one side. It teaches you to resist better before moving more.

7. Controlled Lumbar Extension

Some people don’t need “more intensity” in their lower back. They need to regain extension gently. Controlled lumbar extension fits right in there, especially if you wake up curled up, without fluidity, and with a feeling of tightness in the front.

It can be approached as a gentle opening sequence, with deep breathing and moderate intensity. The important thing is not to force a perfect yoga posture. The important thing is to restore mobility to the area without triggering muscle guarding.

When it is most useful

This type of work usually suits those who spend many hours sitting and get used to living in flexion. It can also help those who, upon getting up, feel their back “folded forward” and need a few minutes to loosen up before walking normally.

A surface with good pressure distribution can make this start more comfortable if the floor feels too hard first thing in the morning. The advantage isn’t just comfort. It’s that you reduce pressure points and focus better on breathing and moving.

Move until you feel openness, not until you find pain.

How to practice it properly

Do the extension progressively and accompany it with long breaths. If at any point the lower back tenses up more than it should, reduce the range. Your body is asking you for less intensity, not more persistence.

  • Look for softness: the movement should feel expansive, not aggressive.
  • Keep your breathing fluid: it helps lower tension.
  • Use it in the morning: it usually fits better when there is still accumulated stiffness.

Among the best lower back exercises, this one doesn’t stand out for pure strength, but for improving the relationship between mobility, breathing, and the feeling of space in the lumbar area. And that, done well, changes a lot about how you start the day.

8. Quadruped Shoulder Tap

This exercise seems simple until you try not to move your pelvis. That’s when its true value appears. The shoulder tap on all fours forces the body to stabilize while you remove one point of support, something very useful for training lumbar control and coordination.

It’s a good progression after the bird dog. You maintain the all-fours position, but now the challenge is to resist the side-to-side sway when one hand lifts to touch the opposite shoulder.

What to observe in each repetition

Position yourself with your hands and knees well supported. Activate your core and separate your knees slightly if you need a wider base. Then touch one shoulder with the opposite hand and return slowly.

If your hips sway to the side when you lift your hand, you’re using momentum instead of control. Slow down. You can even start with very small movements until you master stability.

A typical case is someone who has strength but little core coordination. Active people, even trained ones, discover with this movement that their pelvis rotates more than they thought. That awareness is already part of the work.

How to integrate it at home

The surface matters quite a bit because it protects your wrists and knees, but it shouldn’t be so soft that it robs you of stability. A padded and firm mattress can work well for short sets in the morning or as part of a bedroom routine.

  • Tap lightly: don’t drop your weight suddenly onto the shoulder.
  • Look at the floor: it helps keep your neck neutral.
  • Go slowly at first: speed comes later.

If you're looking for the best lower back exercises that also improve control in everyday movements, this deserves a permanent place. It doesn't just strengthen. It teaches you not to lose alignment when the body is no longer perfectly symmetrical.

Beyond Exercise and the Ergonomics of Your Rest

Integrating these movements into your daily routine can greatly change how your lower back feels. Not because there is a magic exercise, but because the back responds well to a combination of stability, mobility, strength, and quality rest. When you choose a few movements and do them consistently, the body stops improvising and starts protecting the spine better.

If you want a simple starting point, choose three or four exercises from this list and practice them upon waking. Dead bug, bridge, cat-cow, and bird dog form a very balanced combination for many people. They help you activate your core, move your pelvis with more control, and prepare your back before sitting, walking, or lifting weight.

At the same time, it is worth remembering something that is often overlooked. The environment where you perform these movements matters. And the surface you sleep on even more. If you spend the night on a mattress that sinks you too much or does not maintain reasonable alignment, you will wake up stiffer, with less body awareness and more difficulty starting the day well.

In the gym, deadlifts and hyperextensions are very effective exercises for the lower back. They are very useful movements, but also more demanding and require more technique. That is why, for many people, it makes sense to start with floor variants like the ones you have seen here and progress under the guidance of a professional.

Another important nuance is that not everyone starts from the same point. The work context, age, and history of discomfort greatly change the choice of exercise. The practical idea is clear: the routine and rest must adapt to the real person, not to the perfect exercise on paper.

If the pain is acute, sharp, or radiates down your legs, consult a doctor or physical therapist. That is not something to push through on your own. But if what you notice is stiffness, weakness, or recurring tension, the 360-degree approach works very well: move better, sleep better, and use a surface that helps, not hinders.

Morfeo mattresses fit well into that logic: they seek firm support that holds the lumbar area without sacrificing comfort. Taking care of your back does not just mean doing exercises. It also means resting on a surface that lets you start the morning with less stiffness.

Morfeo's Recommendation

What You Do During the Day Should Not Be Undone at Night

Strengthening the lumbar area helps, and sleeping with an aligned spine does too: a core that does not let the hips sink and a layer that relieves the shoulders. If the pain persists, consult your doctor or physical therapist.
