Deadlift Form Fix: 7 Mistakes Killing Your Back (And How to Fix Them)

If you’ve ever struggled with lower back pain or wondered why your deadlifts feel so awkward, you’re not alone. Nearly 50% of lifters mess up their deadlift form — leading to subpar performance and increased injury risk.

But it doesn’t have to be this way. With a few simple tweaks, you can perfect your deadlift technique and start pulling bigger weights safely. In this comprehensive guide, we’ll break down the 7 most common deadlift form mistakes and show you how to fix them.

1. Rounding the Lower Back

One of the biggest deadlift form killers is rounding the lower back. This takes tension off your hamstrings and glutes, shifting the load to your lower back — which can lead to serious injury.

According to a 2015 study, lifters who rounded their lower backs during the deadlift experienced 3.6x greater spinal compression forces compared to those who maintained a neutral spine position.

To fix this, focus on keeping your chest up and shoulders pulled back throughout the lift. Brace your core like you’re about to get punched in the stomach. This will help you maintain a neutral spine position and transfer more force to your legs.

2. Excessive Knee Bend

Many lifters make the mistake of bending their knees too much at the start of the deadlift. This puts the hips in a mechanically disadvantaged position, limiting your strength and range of motion.

The ideal knee bend should be just enough to get your shins to vertical — any more and you’ll be in a squat-style hip hinge rather than a true deadlift.

To fix this, focus on hinging at the hips to initiate the lift. Imagine you’re trying to stick your butt out behind you as you grip the bar. This will help you maintain a more upright torso position and recruit your posterior chain muscles more effectively.

3. Locking Out Too Early

Another common deadlift form issue is locking out the hips and knees too early. This causes you to lose tension in your posterior chain, making the lift harder.

Instead, you should focus on driving through your heels to fully extend your hips and knees at the top of the lift. This ensures you’re getting maximal glute and hamstring activation throughout the movement.

To cue this, imagine you’re trying to crush a soda can between your feet as you stand up. This will help you maintain that posterior chain tension and finish the lift strong.

4. Letting the Bar Drift Forward

A major deadlift form flaw is letting the bar drift too far forward over the course of the lift. This shifts the load to your lower back and makes the lift significantly harder.

According to a 2018 study, lifters who kept the bar path closer to their center of mass experienced 21% less compressive forces on their spine versus those who let the bar drift.

To fix this, focus on keeping the bar path vertical and pulling it straight up along your body. Imagine you’re trying to rip the floor apart as you lift — this will help you drive the bar straight up without drifting.

5. Incorrect Grip Width

Believe it or not, your grip width can have a big impact on your deadlift form and performance. Gripping the bar too wide or too narrow can put your shoulders in a mechanically disadvantaged position.

The ideal grip width is just outside shoulder-width. This allows you to keep your elbows tucked and your shoulders in a strong, stable position throughout the lift.

To find your perfect grip width, stand with your feet hip-width apart and let your arms hang straight down. The distance between your hands should be about the same as the distance between your shoulders.

6. Not Bracing Properly

Proper bracing is essential for safe, effective deadlifts. If you don’t brace your core, you’ll lose tension and energy transfer — leading to back pain and poor performance.

To brace effectively, take a big breath into your belly before you lift, then squeeze your abs like you’re about to get punched. Maintain this braced position throughout the entire lift.

According to a 2013 study, lifters who braced their core experienced 28% less compressive forces on their spine compared to those who didn’t brace.

7. Incorrect Foot Position

Your foot position plays a big role in your deadlift stability and power transfer. Placing your feet too narrow or too wide can limit your leverage and force production.

The ideal foot position is hip-width apart, with your toes pointed slightly outward (about 15-30 degrees). This allows you to drive through your heels and engage your glutes and hamstrings more effectively.

To set up, stand with the barbell over the middle of your feet. Your heels should be about 1-2 inches from the bar. Grip the bar with your hands just outside your legs, then take a big breath and lift.
