10 Common Deadlift Mistakes and How to Fix Them

The deadlift is arguably the most natural human movement—picking something heavy off the ground. Yet it's also the lift that causes the most anxiety about form. This guide breaks down the most common deadlift mistakes, explains why they happen, and gives you practical fixes.

Why Deadlift Form Matters

Deadlifts have a reputation for being "dangerous," but they're only dangerous with poor technique or loads you can't control:

• The spine wants to stay neutral under load—rounding increases shear forces
• Proper hip hinge mechanics load your glutes and hamstrings, not your lower back
• Good form moves more weight—inefficient technique leaks force

Mistake #1: Rounded Lower Back

What it looks like: Lower back rounds during the pull, especially off the floor.

Why it happens:

• Starting position is wrong (hips too high or low)
• Can't maintain brace under load
• Weak spinal erectors
• Going too heavy
• Hamstring/hip flexibility limitations

How to fix it:

Setup check:

• Bar over mid-foot (not against shins yet)
• Shins touch bar by pushing knees forward slightly
• Hips high enough that shoulders are over or slightly in front of bar
• Chest up, lats engaged ("protect your armpits")

Bracing:

• Big belly breath BEFORE you pull
• Push belly out against belt/waistband
• "Show your chest to the wall in front of you"

Strengthening exercises:

• Deficit deadlifts (lighter weight)
• Paused deadlifts (1-2 inches off floor)
• Romanian deadlifts
• Good mornings
• Back extensions

When slight rounding is acceptable: Upper back rounding (thoracic) is common in max effort pulls and is generally lower risk than lumbar rounding. Focus on keeping your lower back neutral; upper back rounding can be tolerated if controlled.

Mistake #2: Bar Drifts Away From Body

What it looks like: Bar moves forward away from legs during the pull.

Why it happens:

• Not engaging lats
• Arms bending
• Starting with bar too far from shins
• Upper back weakness

How to fix it:

Lat engagement cues:

• "Protect your armpits"
• "Bend the bar around your legs"
• "Put your shoulder blades in your back pockets"
• "Squeeze oranges in your armpits"

Setup fix: Bar should start over mid-foot, then touch shins when you pull. The bar drags up your legs the entire pull—shins, knees, thighs.

Strengthening:

• Straight arm lat pulldowns
• Barbell rows
• Single-arm dumbbell rows
• Lat-focused pull-ups

Mistake #3: Hips Shooting Up First

What it looks like: Hips rise faster than shoulders, turning the deadlift into a stiff-leg pull.

Why it happens:

• Weak quads
• Starting with hips too low
• Not pushing through the floor
• Leg drive pattern not trained

How to fix it:

Setup adjustment: Your starting hip height should put your shoulders over or slightly in front of the bar. If you start too low (like a squat), your hips will naturally shoot up to the correct position—wasting energy.

Cues:

• "Push the floor away"
• "Leg press the earth"
• "Hips and shoulders rise together"

Drills:

• Pause deadlifts at 1 inch off floor
• Tempo deadlifts (3 seconds to knee)
• Block pulls (eliminate the weak range)
• Front foot elevated split squats (quad strength)

Video check: Film from the side. Draw a line from shoulder at setup to shoulder at knee height. It should be nearly vertical, not horizontal movement.

Mistake #4: Jerking the Bar Off the Floor

What it looks like: Yanking the bar with arms, bar whips, inconsistent starting position.

Why it happens:

• Not taking slack out of bar
• Rushing the lift
• Arms not locked straight
• Mental approach (trying to be explosive)

How to fix it:

Taking the slack out: Before you pull, "pull" against the bar without moving it:

1. Get in position, grip the bar
2. Engage lats, straighten arms
3. Pull just enough to hear the bar click against the plates
4. Feel tension from hands through legs into floor
5. NOW push and pull

Cues:

• "Squeeze the bar off the floor"
• "Make the bar bend before it leaves the ground"
• "Build pressure, then lift"

Arms should be:

• Completely straight throughout
• Like "hooks" or ropes connecting you to the bar
• Never actively pulling with biceps (injury risk)

Mistake #5: Hyperextending at Lockout

What it looks like: Leaning back excessively at the top, lower back crunches.

Why it happens:

• Misunderstanding "full lockout"
• Weak glutes (compensating with back extension)
• Powerlifting cue taken too far

How to fix it:

What lockout should look like:

• Hips fully extended
• Knees fully extended
• Shoulders over hips (vertical torso)
• NOT leaning backward

Cues:

• "Stand tall"
• "Squeeze your glutes, not your back"
• "Hips to the bar"
• "Finish with your hips, not your back"

Why it matters: Hyperextension loads the facet joints and can cause lower back pain over time. Full hip extension gives you the benefits without the risk.

Mistake #6: Looking Up During the Pull

What it looks like: Head cranked back, watching ceiling or mirror.

Why it happens:

• Trying to "keep chest up"
• Watching form in mirror
• Habit

The problem: Cervical hyperextension can cause neck strain and actually makes it harder to brace properly. Your spine works as a unit—cranking one end affects the other.

How to fix it:

Proper head position:

• Neck neutral (packed)
• Look at floor 6-10 feet ahead at setup
• Head naturally rises as you stand up
• At lockout, look forward normally

Cue:

• "Double chin" or "pack your neck"
• "Chin tucked"

Mistake #7: Stance Too Wide or Narrow (Conventional)

What it looks like: Awkward pull, arms contact thighs, can't get in good position.

Why it happens:

• Not experimenting with stance
• Copying someone else
• Long arms or short arms affecting optimal position

How to find your stance (conventional deadlift):

The jump test: Stand relaxed, then jump straight up. Where your feet land is approximately your deadlift stance width.

General guidelines:

• Narrower than your squat stance
• Feet roughly hip width
• Toes pointed out 15-30 degrees
• Arms hang straight down outside of legs

Signs your stance is wrong:

• Arms hitting thighs during pull
• Can't get shoulders over bar
• Knees cave in (too wide)
• Feel cramped (too narrow)

Mistake #8: Trying to Squat the Deadlift

What it looks like: Hips very low at start, shoulders behind bar, knees way over bar.

Why it happens:

• Treating deadlift like a squat
• "Keeping back straight" taken too far
• Fear of hip hinge

The reality: The deadlift is a HIP HINGE, not a squat. Your hips will be higher than you think, and that's correct.

Setup comparison:

Squat:

• Shoulders over mid-foot
• Hips between knees and shoulders
• Very upright torso

Deadlift:

• Shoulders over or slightly past bar
• Hips above knees
• Torso at 45-degree-ish angle

How to fix it:

• Practice Romanian deadlifts (pure hip hinge)
• Hip hinge with dowel on back (head, upper back, tailbone contact)
• Block pulls (starts you in correct position)

Mistake #9: Inconsistent Setup

What it looks like: Different starting position every rep, some good, some bad.

Why it happens:

• No systematic setup routine
• Rushing
• Adjusting during the lift instead of before

How to fix it:

Create a setup checklist (example):

1. Walk to bar, feet under bar (bar over mid-foot)
2. Grip bar (same grip width every time)
3. Shins to bar (knees forward)
4. Chest up, lats engaged
5. Big breath, brace
6. Pull slack out
7. Push and pull

Practice:

• Do your full setup on every warmup set
• Video yourself to verify consistency
• Make setup a ritual

Mistake #10: Mixed Grip Problems

What it looks like: Bicep pain, bar rotating, uneven loading.

Why it happens:

• Mixed grip with bent arm (supinated side)
• Always using same over/under orientation
• Grip wider than necessary

How to fix it:

Mixed grip safety:

• Keep BOTH arms completely straight
• Don't pull with the underhand arm—let it hang
• Alternate which hand is over/under (or use hook grip)

Alternatives:

• Hook grip (thumb under fingers)—uncomfortable but symmetric
• Straps for working sets (train grip separately)
• Double overhand as long as possible (builds grip)

When to use mixed grip: Only when double overhand fails AND you're doing a near-max single or testing grip. Most training can use double overhand or straps.

Conventional vs. Sumo: Choosing Your Style

Not a mistake per se, but pulling the wrong style for your body is a common issue.

Consider conventional if:

• Shorter arms
• Longer torso
• Strong back
• Good hip hinge mobility

Consider sumo if:

• Longer arms
• Shorter torso
• Wider hips
• Hip mobility limitations in conventional

How to test: Pull both styles for 4-6 weeks with submaximal weight. Your stronger/more comfortable style usually matches your anatomy.

Deadlift Setup Checklist

Use this every rep until it becomes automatic:

1. Feet: Under bar, hip width, toes out slightly
2. Grip: Bar in fingers (not palm), just outside knees
3. Shins: Touch bar without moving it
4. Hips: Set back, higher than knees
5. Chest: Lifted, showing your logo to the wall
6. Lats: Engaged ("protect armpits")
7. Breath: Big belly breath, brace hard
8. Slack: Pull out slack, feel tension build
9. Pull: Push floor away, drag bar up legs
10. Lockout: Squeeze glutes, stand tall (not back)

Common Pain Points and Fixes

Lower Back Pain

• Check: Starting position, bracing, weight selection
• Usually: Rounding at lumbar spine, hips too high, or too heavy

Knee Pain

• Check: Bar path, stance, lockout
• Usually: Bar drifting forward, hitting knees during pull

Neck Pain

• Check: Head position
• Usually: Looking up instead of neutral neck

Bicep Pain (Supinated Side)

• Check: Arm straightness in mixed grip
• Usually: Bent arm on underhand side—always lock arms completely straight

Shin Scraping

• This is normal if mild
• Wear long socks or pants
• Severe scraping might mean bar too close at start

4-Week Deadlift Form Fix Program

Week 1: Assessment & Hip Hinge

• Video current deadlift from side and 45 degrees
• Identify 1-2 biggest issues
• Daily hip hinge practice (RDLs, good mornings)

Week 2: Position Work

• Pause deadlifts (2 sec at 1" off floor): 5x3 at 60%
• Block pulls from knee: 4x5 at 70%
• Focus on setup consistency

Week 3: Tempo Control

• Tempo deadlifts (3 sec up): 5x3 at 65%
• Deficit deadlifts (2"): 4x5 at 60%
• Video check mid-week

Week 4: Integration

• Regular deadlifts with strict setup: work up to 5x3 at 75%
• One heavy single at 85% with video
• Assess improvement, plan next focus

Key Takeaways

1. The deadlift is a hip hinge, not a squat—hips will be higher than you think
2. Slack out of the bar is non-negotiable—this fixes many problems instantly
3. Neutral spine means neutral—including your neck
4. The bar stays close—touching your body the entire pull
5. Lockout is full hip extension, not back extension

Most deadlift problems trace back to setup issues. Nail your setup, be patient off the floor, and the rest tends to follow. Film yourself regularly—you can't fix what you can't see.
