What’s Really Going Wrong With Your Back When You Press Overhead
If you experience pain or discomfort in your lower back when pressing overhead, you are likely dealing with a common issue among athletes.
Overhead pressing is a foundational movement in CrossFit and strength training, critical for building upper-body strength and shoulder stability.
Pain in your lower back can limit your performance, reduce your confidence in training, and increase your risk of injury.
Understanding why this happens is essential for improving your lifts and protecting your spine.
This week’s newsletter will explain the mechanics behind overhead pressing, identify why your lower back becomes involved, and provide strategies to address the root causes so you can press pain-free and effectively.
The Overhead Press and Spine Mechanics
When you press a bar overhead, your body relies on precise coordination between your shoulders, spine, and core.
Your thoracic spine must extend to allow your arms to reach full overhead range without forcing your lower back into excessive arching.
Your scapulae rotate upward to position your shoulder blades in a stable alignment for pressing.
Your core muscles engage to create stiffness in your trunk, stabilizing your pelvis and lumbar spine throughout the movement.
If your thoracic spine lacks mobility, your shoulders cannot reach the proper position.
If your core is weak or underactive, your lumbar spine takes extra load.
Your lower back becomes the primary compensator, arching to help the bar reach overhead.
This compensation increases stress on your lumbar vertebrae and surrounding muscles.
Understanding how these systems interact is key to correcting your technique and reducing lower back discomfort when you press overhead.
Main Reasons Your Lower Back Hurts
Limited Shoulder Mobility
When you lack sufficient shoulder mobility, you are forced to rely on your lower back to achieve the overhead position.
Your lats, pecs, and thoracic spine can restrict your ability to reach full extension in your shoulders.
When these areas are tight, your thoracic spine cannot extend enough, so your lumbar spine arches to compensate.
This compensation increases stress on the vertebrae and surrounding muscles.
You may notice your lower back flaring excessively as you press the bar overhead or experience stiffness after pressing.
Improving your shoulder and thoracic mobility is necessary to reduce this reliance on your lower back and allow your shoulders to move freely.
Weak or Underactive Core
If your core is weak or underactive, your trunk cannot stabilize effectively.
This forces your lower back to take extra load to keep the bar overhead.
You may feel your lumbar muscles working harder than your shoulders or notice fatigue in your lower back before your arms.
Over-reliance on spinal extension places stress on your lumbar discs and posterior chain.
Strengthening your core with anti-extension exercises allows you to create stiffness in your midsection, keeping your spine neutral and reducing the burden on your lower back during pressing movements.
Poor Ribcage and Pelvic Position
When your ribcage flares or your pelvis tilts anteriorly, your lumbar spine moves into hyperextension during overhead pressing.
Your breathing mechanics influence this alignment because improper diaphragmatic engagement changes the relationship between your ribs, spine, and pelvis.
If you do not stabilize your ribcage and pelvis, the lower back automatically arches to support the lift.
Correcting your posture, engaging your glutes, and coordinating your breath can help you maintain a neutral spine and relieve stress on your lower back while pressing.
Technique Errors and Loading
You can amplify lower back stress by overarched while lifting heavy loads, pressing from behind the head, or failing to brace properly.
Fatigue further compounds these errors, causing your lower back to absorb more force.
Paying attention to bar path, maintaining a neutral spine, and controlling the load reduces excessive strain.
Even small adjustments in technique can prevent compensatory lumbar extension and make pressing safer and more efficient.
How to Fix It
You can reduce lower back discomfort by addressing mobility, core strength, technique, and programming.
Improving thoracic extension and stretching your lats and pecs increases shoulder range of motion, allowing your spine to remain neutral.
My go-to exercises:
T-Spine Extension over Foam Roller
Supine PVC Eccentric Shoulder Flexion
Core training through anti-extension exercises such as planks, dead bugs, and hollow holds, enhances trunk stability and prevents your lumbar spine from taking excessive load.
My go-to exercises:
Forearm Plank
Hollow Holds
You should focus on keeping your ribcage neutral, glutes engaged, and bar path consistent while pressing.
Adjusting your programming is equally important.
Scale loads appropriately, perform strict pressing work before push presses or jerks, and control the tempo of your lifts.
You can also consider utilizing the Landmine Press as it does not demand a complete overhead position.
Managing fatigue ensures that your muscles can maintain proper alignment throughout the movement.
Applying these strategies consistently allows you to press overhead with improved mechanics and reduced lower back stress.
Wrapping Up on Low Back Pain and Pressing
Most lower back pain when pressing overhead arises from compensations, not the movement itself.
By improving your shoulder mobility, strengthening your core, and refining your technique, you can press overhead pain-free and effectively.
With consistent mobility and strengthening, you’ll have less discomfort and more confidence pressing overhead.
Give these drills a shot in your main programming or as accessory training, and let me know if you have any questions!
