There’s more to the deadlift than pulling weight off the floor. I’ve watched hundreds of lifters grind away for years on this exercise and make zero progress — not because they lacked effort, but because their technique was silently working against them.
The deadlift is a must-have for building full-body strength and muscle. But because it involves heavy loads, the margin for error is smaller than almost any other exercise. Poor form doesn’t just limit your progress — it puts your lower back, spinal discs and hips at serious risk. A herniated disc from a bad deadlift can sideline you for months.
Nobody was born with perfect form. Mistakes are inevitable, especially early on. But there are ten specific errors that show up over and over — in every gym, at every experience level. Remove these from your training and you’ll lift more, get stronger and stop getting hurt.
Mistake #1 — Squatting Your Deadlifts
The deadlift is not a squat. It never was. The bar starts on the floor, you pull it, and that’s a rep. The bar does not get unracked, lowered and deadlifted back up — that’s a squat with extra steps.
When you deadlift with hips too low — like a squat setup — your shins come forward and the bar hits them on the way up. That’s an immediate sign your position is wrong.
The fix: Set up with the bar over your mid-foot, shoulder blades directly over the bar, hips in the position that naturally results from that setup. Exact hip height depends on limb length, but the mid-foot/shoulder-blade cue is universal. Get that right and the squat problem disappears.
To fix this mistake you must learn proper hinging and look at the deadlift like a hinge movement rather than just a squat movement. This way the bar will never hit your knees again.
Mistake #2 — Bouncing Your Deadlifts
Bouncing the bar off the floor between reps is cheating — full stop. When the bar rebounds, it travels to mid-shin on its own. You didn’t lift it. That means you’re doing half-reps and convincing yourself you’re stronger than you are.
Beyond the ego problem, bouncing removes the hardest part of the lift — breaking the bar off the floor from a dead stop — which is exactly the part that builds real strength. It also makes it harder to maintain a neutral lower back, which spikes injury risk.
The fix: Let the bar settle completely between reps. Reset your brace, reset your position, then pull. Every rep should be a true deadlift from a dead stop.
If you can’t pull it from a dead stop, the weight is too heavy, lower the weight.
Mistake #3 — Leaning Back at the Top
Hyperextending at lockout feels like a strong finish. It isn’t. What it actually does is compress your lumbar discs and squeeze the vertebrae in your lower spine. Do it enough under heavy loads and you’re looking at a serious injury.
Shrugging at the top is equally pointless and equally damaging. There is no muscle-building benefit to either.
The fix: At lockout, simply stand tall. Hips and knees locked, shoulders directly above hips. Ears, shoulders, hips, knees and ankles in a straight vertical line. That’s it. No lean, no shrug, no drama.
Mistake #4 — Hitting Your Knees on the Way Down
This is uncomfortable, obvious and yet incredibly common. More importantly, when the bar hits your knees on the descent, it gets pushed forward off the vertical line — which means it lands over your forefoot instead of your mid-foot. That forces your next rep to start from a worse position, adding unnecessary stress to your lower back on every pull.
The fix: On the descent, move your hips back first. Let the bar pass the knees, then bend them to bring the weight to the floor. Done correctly, the bar lands over your mid-foot and your next rep starts from a proper setup automatically.
Mistake #5 — Not Letting the Bar Touch the Floor
Some lifters avoid touching the floor between reps to maintain tension. The logic sounds reasonable. The reality is different.
Touching the floor gives your lower back a brief reset between reps, allowing you to re-establish a neutral spine before the next pull. Without that reset, you’re more likely to round the lower back under fatigue — and that’s when discs get compressed.
If you want more tension, add weight. That solves the problem without the injury risk.
The fix: Let the bar touch the floor on every rep. Brief pause, reset the brace, pull again.
Mistake #6 — Destroying Your Shins
Some shin contact is normal and inevitable — dragging the bar along the shins on the way up is actually part of proper technique because it keeps the bar close to the body. Slight scraping is fine.
Bleeding shins every session is not fine. It means you’re either squatting the deadlift (shins too far forward), bouncing (bar coming back into the shins on the rebound), or your bar path is off. The shins are telling you something. Don’t cover them up with tall socks and ignore the message.
The fix: Set up with shoulder blades over the bar, bar over mid-foot, and pull vertically. When the form is right, the bar grazes the shins cleanly without gouging them. If bleeding persists after fixing the form, shin guards are fine as a temporary measure — but form first.
Mistake #7 — Checking Form in the Mirror
I understand the impulse. But the mirror is not your friend during deadlifts.
Looking sideways or up into a mirror while pulling causes you to twist your neck and drop your hips — both of which compromise your position under a heavy bar. Research has also shown that regular mirror use during training can negatively affect balance and rate of force development.
The fix: Film yourself instead. Set your phone perpendicular to your line of pull and review it after your sets. You’ll see more from a 10-second video than from a hundred mirror glances mid-lift — and without the neck pain.
Filming (especially from the side) can help you fix your deadlift form, how low your hips go, do they go up first etc.
Mistake #8 — Using a Belt to Compensate for Bad Form
A weightlifting belt does not support your lower back. What it actually does is give you something to brace against, which increases intra-abdominal pressure and helps maintain spinal stability — but only if you know how to brace properly in the first place.
When lifters with poor form put on a belt, they feel invincible. They lift heavier. Their form breaks down under the extra load. The belt doesn’t save them — it just enables them to get hurt with more weight on the bar.
The fix: Earn the belt. Learn to brace your core without it, build your form until it’s consistent and only add the belt when you’re competing or working at near-maximal loads where the marginal benefit is real. For most training sessions, you don’t need it.
| Who Should Use a Belt | Who Shouldn’t |
|---|---|
| Competitive powerlifters at near-max loads | Beginners still learning to brace |
| Experienced lifters on heavy working sets | Anyone using it as a crutch for bad form |
| Lifters with a history of back injury (with medical guidance) | Anyone whose form changes when the belt comes off |
Mistake #9 — Deadlifting in Running Shoes
Running shoes are engineered for cushioning and shock absorption. That’s exactly what you don’t want under a heavy barbell.
The gel and foam soles compress differently on every rep, creating inconsistency in your positioning. They also absorb the force you’re trying to direct into the floor and transfer to the bar — meaning you’re literally losing strength through your footwear. The elevated heel and unstable platform also increase injury risk by shifting your weight distribution forward.
The fix: Deadlift barefoot if your gym allows it. If not, use hard-soled lifting shoes or flat-soled shoes — Converse, wrestling shoes or purpose-built deadlift slippers all work well. Your feet should be as close to the floor as possible, the sole should be rigid and the heel should be flat or minimally elevated.
Switching to flat shoes with a hard heel, or specialized lifting shoes is the best thing you can do when deadlifting. For me, it made a tremendous difference for my strength.
Mistake #10 — Deadlifting With Gloves
Gloves add thickness between your hand and the bar. A thicker bar is harder to grip. A harder-to-grip bar means fewer reps before your grip gives out.
Most people wear gloves to avoid calluses. Calluses are a natural byproduct of lifting heavy things. They’re not a problem — they’re a badge. If they get too large and start tearing, manage them with a pumice stone weekly and grip the bar low in your palm. Use chalk if your gym permits it.
Building a strong, bare grip will transfer to every other lift in your program. Gloves won’t.
The Common Thread
Look at these ten mistakes together and a pattern emerges: most of them come from one of three sources.
Ego — bouncing, belts, ignoring calluses, avoiding the floor reset. All driven by wanting to look stronger than you are or avoiding discomfort.
Ignorance — squatting the deadlift, wrong shoes, mirror checking. Nobody told you these things and you didn’t know.
Impatience — skipping the floor touch, poor setup, rushing the descent. Trying to get more reps or more weight before the technique is ready for it.
The fix for all three is the same: slow down, use less weight than you think you need, and build the form first. The strength follows automatically.
