Does Deadlift Work Lower Back?

Deadlifts work your posterior chain which consists of your hamstrings, quads, glutes, erector spinae, lats, and trapezius. Other synergist and accessory muscles also contribute when performing the correct deadlift technique.

With different deadlift variations changing the degree to which muscle groups are recruited, do deadlifts work your lower back? Which variations work which muscles? I’ve discussed this below.

What Is a Deadlift?

Before I talk about deadlifts and lower back health, we need to look at the biomechanics of the deadlift movement and which muscles are used. Deadlifts are classed as a compound movement meaning you need to use a large number of muscle groups to perform the exercise correctly. They involve picking a weighted barbell up off the floor and pulling it up your body until your legs and extended and the barbell is in line with your torso.

Whilst they sound fairly simple, deadlifts require your body to go through several movement patterns, with your muscles working together to keep your body aligned correctly. Let’s take a look at the deadlift movement in more detail and what muscles are involved:

During the deadlift movement, the following joint actions occur:

• Hip Extension (Driving through the hips)
• Knee Extension (Straightening the knees)
• Shoulder Retraction (Bringing the shoulders backward)

The hip and knee extension are the primary movements used during the deadlift, with shoulder retraction classed as secondary. Both these movements engage the leg and back musculature to different degrees depending on the deadlift variation being performed.

The muscles worked during the deadlift include the:

• Erector Spinae
• Hamstrings
• Glutes
• Quadriceps
• Latissimus Dorsi
• Trapezius
• Rhomboids
• Abdominals and Obliques

Performing a deadlift correctly requires each of the muscle groups above to work together. Each muscle group will be activated at varying degrees at different stages of the lift, with deadlift variations changing this as the movement pattern differs.

At the bottom portion of the deadlift, you pull the barbell off the floor. Whilst it requires most of your upper and lower body to work together, the quads are primarily responsible for driving the barbell off the floor.

As you pull the bar upwards, your hamstrings and glutes start to work together to extend your hips slightly as you bring the barbell toward your knee.

As the barbell comes over your knees, your glutes, quads, and hamstrings work together, so you’re able to extend your knees and drive through your hips to pull the bar up your body.

Your abdominal and oblique muscles work to keep your core braced throughout the movement, creating intraabdominal pressure and allowing you to maintain a neutral spine when lifting. Your lats help to keep the barbell close to your body and alongside the erectors, prevent upper back rounding which can cause injury.

With this, do deadlifts work your lower back muscles? What do your lower back muscles do?

Erector Spinae

The erector spinae muscles, more commonly known as your lower back muscles, run along the outside of your spine. They extend along the lumbar, thoracic, and cervical spine sections. They make up part of your lower back region and provide spinal protection.

During the deadlift, the erectors keep your back flexed and extended, preventing it from rounding and leading to possible injury. Maintaining a stable spine under tension is important to not place too much stress on the spinal column if it needs to take most of the weight.

The erectors also help with back extension, allowing the spine to move to an upright position as the barbell comes off the floor. Depending on the deadlift variation, starting in a more horizontal position will recruit more of the erector muscles.

Are Deadlifts Good for Lower Back Health?

When performed correctly, deadlifts are great exercises for improving lower back health and preventing possible injury. Here’s why:

Deadlifts Strengthen Your Spine

The external load provided when deadlifting creates stress on our lower back musculature and lumbar spine region. Our bodies are highly adaptable and able to handle large amounts of compression forces placed upon them. They are designed to change, allowing us to deal with the stress and learn how to overcome it.

As our bodies adapt to stress, the tissue changes result in a stronger lower back which includes our lumbar spine and erector spinae muscles surrounding it. This also translates into better functional movement patterns such as carrying household objects or bending down to pick something up.

Deadlifts Develop Our Posterior Chain

Having a strong posterior chain is extremely important to maintain good lower back health whether you’re in the gym or performing daily activities at home or work. Building stronger glute and hamstring muscles through deadlifting increases our ability to handle heavier loads and takes stress off the lower back musculature when lifting from the ground. 

Correct Deadlifting Can Provide Back Rehabilitation

When performed correctly, deadlifting can improve back pain, mobility, and function. Focusing on performing a correct hip hinge whilst engaging your posterior chain correctly can help to promote correct movement patterns and therefore decrease pain incidence. 

How do Different Types of Deadlifts Affect Your Lower Back?

Different deadlift variations place different stress on your lower back due to the starting position and different movement planes used. So, do Romanian deadlifts work your lower back? What about the other deadlift variations?

Leg-focused deadlift variations include sumo deadlifts, deficit deadlifts, and trap bar deadlifts. Sumo deadlifts are performed with your legs outside your arms, placing a higher amount of stress on your quads and adductor muscles rather than your lower back.

Deficit deadlifts start with an elevated foot position, placing more stress on your hamstrings, quads, and glutes. Lower back activation is similar to conventional deadlifts. Trap bar deadlifts use a higher starting position, recruiting the quads more and placing less stress on your lower back. They are great for people who suffer from lower back pain.

Back-focused deadlift variations include snatch grip deadlifts and stiff leg deadlifts. Snatch grip deadlifts are where you use a wide barbell grip, which puts you in more of a bent-over starting position. This places more stress on your lower back muscles.

So, do stiff leg deadlifts work your lower back? They involve less knee flexion, with the higher hip position and parallel back placing more stress on your glutes, hamstrings, and lower back. 

What Causes Back Pain When Deadlifting?

As deadlifting places significant stress on your spine region, it’s normal to feel sore after lifting. However, excessive soreness or pain may be a sign that you’re doing something incorrectly. Here are some of the possible causes:

Lower Back Arching – This is one of the most common mistakes made when deadlifting. It’s also known as rounding the lower back and puts excessive strain on your lumbar spine region, leading to pain.

Early Hip Drive – If your hips come up before the rest of your body, you’re driving them too early. This often results from too much weight on the barbell or an incorrect starting position. Driving your hips too early places more stress on your lower back, increasing the risk of pain and injury.

Incorrect Bracing – To maintain a neutral spine, you need to create enough intra-abdominal pressure to keep your core strong and posterior chain correctly aligned. Incorrect bracing may lead to the wrong lifting position, placing more stress on your back.

Lack of Barbell Control – Using a small amount of momentum when lifting is okay if done correctly. Control needs to be maintained when lifting the barbell up and down, not just up. Make sure to maintain a tight body position when lowering the barbell under control. Unnatural jerking movements when lowing the bar may lead to back injuries as you come out of an unnatural lifting position. 

Correct Deadlifting Can Provide Back Rehabilitation

Having a strong posterior chain is extremely important to maintain good lower back health whether you’re in the gym or performing daily activities at home or work. Building stronger glute and hamstring muscles through deadlifting increases our ability to handle heavier loads and takes stress off the lower back musculature when lifting from the ground.

FAQ

What Part of the Back Do Deadlifts Work?

Deadlifts work your whole posterior chain which consists of your upper and lower back. Back muscles recruited during the deadlift movement include your trapezius, latissimus dorsi, erector spinae, and lower back muscles.

Each muscle works together to support your spine and trunk musculature and activate at varying degrees during the movement.

Which Deadlift Variation Is the Best for Your Lower Back?

Straight leg deadlifts are performed with a minimal knee hinge, meaning most of the load is transferred to your lower back region. This makes them ideal for those with stronger hamstrings and glutes but a weaker lower back. 

Where Should You ‘Feel’ Deadlifts During the Lift?

Deadlifts are classed as a compound movement, meaning they work the full body. The main muscles worked are part of the posterior chain which includes your glutes, hamstrings, lats, and lower back.

The muscles felt during the deadlift vary depending on the variation performed and your training level. If you’re a beginner, you’ll likely feel it more in the lower back region to start.

Do Hex Bar Deadlifts Work Your Lower Back?

Hex bar deadlifts engage the same muscles as conventional deadlifts. However, due to the higher starting position, they place more stress on your quads and less on your lower back area.

Conclusion

Deadlifts work your whole posterior chain, which includes your lower back muscles. The degree of lower back muscle activation depends on the deadlift variation performed, with snatch grip and stiff leg deadlifts being more back-dominant movements.

Back pain when deadlifting is caused by incorrect technique which may result from too much weight being loaded on the bar or lack of knowledge.
