Deadlifts Hurt My Lower Back: How to Fix Back Pain When Deadlifting

The deadlift is one of the best exercises for building total-body strength—including a strong, resilient back. But if your back hurts during or after deadlifts, something needs fixing. Let's troubleshoot.

First: Understand the Pain

Normal vs. Problem Pain

Normal after deadlifts:

• General fatigue in lower back muscles
• Mild stiffness that resolves within 24-48 hours
• Muscle soreness (DOMS), especially when you're new to the movement

Problem pain:

• Sharp pain during the lift
• Pain that shoots down your leg
• Pain that worsens over days
• Inability to stand up straight after
• Localized point tenderness on spine

If you have problem pain, rest from deadlifts and see a professional. If it's technique-related fatigue, read on.

Common Causes and Fixes

1. Rounding Your Lower Back (Lumbar Flexion)

The Problem: This is the #1 cause of deadlift-related back pain. When your lower back rounds under load, the discs and ligaments take stress instead of muscles.

How to Check: Video yourself from the side. Your lower back should maintain a neutral curve (slight arch) throughout the lift.

The Fix:

• Set your back before you pull: Chest up, lats engaged, "proud chest"
• Brace your core: Big breath into your belly, tighten like you're about to be punched
• Don't start with hips too low: If you're squatting the deadlift, your back will round
• Reduce weight: Ego is the enemy—use a load you can control
• Hip hinge pattern work: Practice RDLs with light weight

2. Bar Too Far From Body

The Problem: When the bar drifts forward, the lever arm increases and your back works much harder.

The Fix:

• Start with bar over mid-foot: Not against shins, not over toes—mid-foot
• Drag the bar up your legs: It should scrape your shins (wear long socks)
• Cue "push the floor away": Instead of pulling the bar up
• Lats engaged: "Protect your armpits" or "bend the bar around your legs"

3. Hyperextending at the Top

The Problem: Leaning back excessively at lockout compresses the spine.

The Fix:

• Stand tall, don't lean back: Hips forward, shoulders over hips
• Squeeze glutes to finish: The glute squeeze brings hips forward
• Stop when you're upright: No need to hyperextend

4. Jerking the Weight

The Problem: Yanking the bar creates a sudden spike of force through your spine.

The Fix:

• "Take the slack out": Before you pull, pull gently until you feel tension in the bar and your body
• Smooth initiation: Accelerate gradually, don't jerk
• Push the floor, don't pull the bar: Mental cue for smoother lifting

5. Hip Mobility Limitations

The Problem: If your hips don't hinge well, your back compensates.

The Fix:

• 90/90 hip stretch: Daily
• Hip flexor stretching: Tight hip flexors prevent full hip extension
• Elevated deadlifts: Start with plates on blocks to reduce range of motion
• Sumo or trap bar: May fit your anatomy better

6. Weak Core / Bracing

The Problem: Your core cylinder stabilizes your spine. Weak or poorly-timed bracing = unstable spine.

The Fix:

• Practice bracing: Breath into your belly (360°), create pressure, hold
• Dead bugs and bird-dogs: Build anti-extension strength
• Pallof press: Anti-rotation core strength
• Belt (maybe): A belt gives you something to brace against, but fix bracing first

Deadlift Variations for Bad Backs

If conventional deadlifts hurt, try these variations while you address the root cause:

Trap Bar (Hex Bar) Deadlift

• More upright torso
• Load is centered around you, not in front
• Often significantly more tolerable
• Great for building strength while protecting back

Sumo Deadlift

• Wider stance, hands inside legs
• More upright torso
• Less lower back stress for many people
• Requires good hip mobility

Romanian Deadlift (RDL)

• Start from the top, hinge down
• Doesn't go to the floor
• Better control of back position
• Excellent for building posterior chain

Block/Rack Pull

• Bar starts elevated (mid-shin or higher)
• Reduced range of motion
• Allows you to practice mechanics with less stress
• Progress to lower starting point over time

Kettlebell Deadlift

• Lighter load, more forgiving
• Good for learning the pattern
• Single KB or double KB

---

The Proper Setup (Step by Step)

1. Stance

• Feet hip-width (narrower than you think)
• Toes straight or slightly out
• Bar over mid-foot

2. Grip

• Bend and grab bar just outside your legs
• Arms straight, no bend

3. Load the Pattern

• Shins to bar (don't move the bar)
• Chest up, lats engaged
• Take breath, brace hard

4. Pull

• Push floor away with legs
• Bar drags up legs
• Maintain neutral spine
• Hips and shoulders rise together

5. Lockout

• Stand tall (not hyperextended)
• Squeeze glutes
• Shoulders over hips

6. Lower

• Hinge at hips first
• Control the descent
• Don't just drop it

Pre-Deadlift Routine

Warm up your back and hips before pulling:

Cat-Cow (2 min)

• Mobilize spine through flexion/extension
• 10-15 slow reps
• Find your neutral spine position

90/90 Hip Stretch (2 min)

• 60 seconds each side
• Opens hips for the hinge

Glute Bridges (1 min)

• 15 reps with pause at top
• Activates glutes before you need them

Light RDL or Good Morning

• Empty bar or light dumbbells
• 10-15 reps
• Practice the hinge pattern

Deadlift Warm-Up Sets

• Start with empty bar: 10 reps
• Add weight gradually: 5 reps per set
• Multiple warm-up sets before work sets

Strengthening for a Bulletproof Back

Hip Hinge Pattern

• RDL: 3 x 10 (lighter weight, strict form)
• Single-Leg RDL: 3 x 8 each (balance and unilateral strength)
• Good Morning: 3 x 10 (posterior chain endurance)

Core Stability

• Dead Bug: 3 x 10 each side (anti-extension)
• Bird-Dog: 3 x 10 each side (anti-rotation)
• Pallof Press: 3 x 10 each side (anti-rotation)
• Plank: 3 x 30-60 seconds (isometric stability)

Hip Strength

• Hip Thrust: 3 x 12 (glute strength)
• Cable Pull-Through: 3 x 15 (hinge pattern, glute focus)
• Reverse Hypers or Back Extensions: 3 x 12 (posterior chain)

---

Mobility Work

Hip Flexor Stretch

Tight hip flexors prevent full hip extension and cause back compensation.

• Half-kneeling hip flexor stretch: 60 seconds each side
• Couch stretch: 60 seconds each side

Hamstring Mobility

Not for everyone, but if hamstrings limit your hinge:

• RDL stretch (bodyweight, hold at bottom): 30 seconds
• Standing hamstring stretch: 30 seconds each side

Thoracic Mobility

• Foam roller thoracic extension: 10-15 reps
• Helps maintain upper back position during pull

Return to Deadlifting Protocol

If you've taken time off due to pain:

Week 1-2: Hip hinge pattern work only (RDLs, good mornings, hip thrusts). No conventional deadlifts. Focus on form.

Week 3-4: Add trap bar or sumo deadlifts at light weight (50% of old working weight). High reps (8-10).

Week 5-6: Progress load gradually (add 5-10% per week). Stay at RPE 6-7.

Week 7-8: Return to conventional deadlifts if desired. Start at 60% of old max.

Ongoing: Prioritize technique over weight. Video yourself regularly. Warm up properly.

Red Flags: When to Stop

Stop deadlifting and see a professional if:

• Pain radiates down your leg (nerve involvement)
• Numbness or tingling in legs/feet
• Loss of bowel or bladder control (emergency)
• Sharp pain during the lift that worsens
• Inability to find any pain-free variation

Key Takeaway

Deadlifts should build your back, not break it. If they hurt, the usual causes are: lumbar rounding, bar too far from body, poor bracing, or inadequate hip mobility. Fix technique first, use variations that don't hurt, and strengthen your core and posterior chain. Most people can deadlift pain-free with proper form and appropriate progression—the key is leaving ego at the door and doing the work to move well before you move heavy.
