The barbell deadlift is a straight pull from the floor to a standing lockout, and getting it right comes down to a precise setup before the bar ever leaves the ground. Most mistakes happen in the first few seconds, not during the pull itself. Here’s how to set up, brace, grip, and execute the lift safely.
Foot Position and Bar Placement
Stand with a narrow stance, feet directly under your hips, with roughly 4 to 6 inches between your heels. Point your toes out slightly, around 15 to 20 degrees. This isn’t a squat stance. Wider foot placement pushes your knees into the path of your arms and forces a less efficient pull.
Walk up to the bar so it sits directly over the middle of your entire foot. That’s not the middle of the visible part of your foot (the area from your toes to your ankle). It’s the middle of your whole foot from heel to toe, which puts the bar about one inch from your shins. If you look down, the bar should cut across the top of your shoelaces. This position keeps the bar over your center of balance for the entire lift.
How to Grip the Bar
With your feet set, bend at the hips and grab the bar just outside your legs. Your arms should hang straight down from your shoulders, not angled outward. A grip that’s too wide increases the distance you have to pull.
You have three grip options, each with tradeoffs:
- Double overhand: Both palms face you. This builds the most raw grip strength and keeps your body symmetrical. The downside is it’s the weakest hold, and the bar will roll out of your hands as weights get heavier. Use this for as long as you can.
- Mixed grip: One palm faces you, the other faces away. This instantly lets you hold more weight because the bar can’t roll in one direction. The tradeoff is that long-term use can create muscular imbalances between your two sides. Alternating which hand you supinate helps reduce this.
- Hook grip: Your thumb wraps around the bar first, then your fingers lock over your thumb. This is one of the strongest grip positions and keeps both hands symmetrical, but it’s genuinely painful on the thumbs until you build tolerance over several weeks.
Start with double overhand. Switch to mixed or hook grip only when your grip becomes the limiting factor, not your legs or back.
Setting Your Back and Hips
Once your hands are on the bar, don’t pull yet. Bend your knees forward until your shins touch the bar. Your hips will drop into position naturally. Don’t squat down to the bar or drop your hips too low. This is a hip hinge, not a squat. The movement centers on your hip joint while your spine stays in a relatively neutral position.
Now lift your chest. Think about showing the logo on your shirt to the wall in front of you. This cue flattens your upper back and sets your spine into a safe, rigid position. Your lower back should have a slight natural arch, not rounded, not hyperextended. Lock your shoulder blades down and back. Your arms are just hooks connecting you to the bar. They stay straight throughout the lift.
Breathing and Bracing
Before you pull, take a large breath into your belly, not your chest. Then brace your core as if someone were about to punch you in the stomach. Hold that breath and that tension. This creates intra-abdominal pressure, which acts like an internal weight belt, increasing spinal stability and trunk rigidity during the lift.
This bracing technique, sometimes called the Valsalva maneuver, is practically unavoidable when lifting heavy loads above 80% of your max. Even at lighter weights, deliberately practicing it protects your spine and teaches you to generate full-body tension. Hold the breath through the entire rep. Exhale at the top once you’re standing, or on the way down.
The Pull: Floor to Lockout
With your breath held, chest up, and arms straight, push the floor away with your legs. The bar should travel in a straight vertical line, staying in contact with your body the entire time. It will drag up your shins (long socks or pants help here), brush past your knees, and slide up your thighs.
The lift breaks into two phases. Off the floor, your legs do most of the work as your knees straighten. Once the bar passes your knees, your hips drive forward to bring you to a full standing position. These phases blend together in one smooth motion. Don’t think of it as two separate steps.
At the top, stand tall with your hips fully extended, shoulders slightly behind the bar, and knees locked. Don’t lean back excessively or shrug your shoulders. The lockout is simply standing up straight.
Lowering the Bar
Reverse the movement by pushing your hips back first, letting the bar slide down your thighs. Once it passes your knees, bend your knees and lower it to the floor. This should be controlled but doesn’t need to be slow. You’re not doing a negative rep on every single deadlift. A quick, controlled descent that keeps the bar close to your body is fine.
Reset your position between reps. The deadlift starts from a dead stop on the floor, which is where the name comes from. Bouncing the bar off the ground robs you of the hardest part of the lift and lets your form deteriorate. Take a breath, re-brace, verify your back is flat, and pull again.
What Muscles the Deadlift Works
The deadlift is a full-body pull, but the load isn’t distributed evenly. Research measuring electrical muscle activity during the conventional deadlift found that the spinal erectors (the muscles running along your spine) and quadriceps show the highest activation levels. The glutes and hamstrings work hard but are secondary drivers. One study recorded hamstring activation at roughly 108% of maximum voluntary contraction and glute activation at about 95%, while the spinal erectors hit around 86%, though the systematic review across multiple studies consistently placed the back and quads as the primary movers.
Within the hamstrings, the inner hamstring muscle activates slightly more than the outer one during deadlifts. This matters if you’re using deadlifts to target specific areas for rehab or sport performance.
Why Your Spine Position Matters
Rounding your lower back under load is the most common cause of deadlift injuries. When your lumbar spine flexes during a heavy pull, shearing and compressive forces increase dramatically on your intervertebral discs, contributing to disc protrusions and herniations. Injury thresholds for lumbar spine segments range between 5,000 to 10,000 newtons of compressive force and 1,000 to 2,000 newtons of shearing force.
Fatigue makes this worse. Studies tracking lifters through repeated sets found that peak lumbar flexion increased from about 35 degrees to 38 degrees over the course of a fatiguing protocol. That may sound small, but it pushed spinal flexion to roughly 34% of the ligaments’ elastic limit. Some researchers use real-time feedback (like an audible tone) when a lifter’s lower back flexion exceeds 80% of their maximum range as a warning threshold. The practical takeaway: stop the set when you can no longer maintain a flat back. Adding reps past that point is where injuries happen.
Shoes and Equipment
What you wear on your feet changes the mechanics of the lift more than you might expect. A shoe sole adds roughly 0.5 to 1.5 inches of height, which means the bar has to travel farther before you reach lockout. Research comparing shod versus barefoot deadlifts found that wearing shoes increased vertical bar displacement by about 3 centimeters, added 17 joules of extra work per rep, and increased time under tension by 0.04 seconds per rep.
If your goal is lifting the most weight possible, flat-soled shoes or barefoot lifting reduces the range of motion and the total work required. Minimalist shoes, wrestling shoes, or deadlift slippers give you a thin, flat, stable base without the cushioning of running shoes. Running shoes are the worst option: the compressible heel creates instability and shifts your weight forward. If your gym doesn’t allow barefoot lifting, a flat shoe with a sole under half an inch thick is the next best thing.
A lifting belt can also help. It gives your core something to brace against, increasing intra-abdominal pressure beyond what you can generate on your own. Save it for your heavier working sets rather than using it for every warmup.
Common Setup Errors
Most deadlift problems trace back to the setup, not the pull. Here are the mistakes that show up most often:
- Bar too far from shins: If the bar starts over your toes instead of midfoot, it pulls you forward and loads your lower back excessively. Reset your feet so the bar is one inch from your shins.
- Hips too low: Trying to squat the weight up shifts the load to your quads and puts the bar out in front of you. Your hips should be higher than your knees but lower than your shoulders.
- Hips too high: This turns the deadlift into a stiff-leg variation and overloads your lower back. If your legs are nearly straight at the start, bend your knees more until your shins touch the bar.
- Jerking the bar off the floor: Yanking creates slack in your arms and rounds your upper back. Instead, build tension gradually by “pulling the slack out” of the bar before the weight breaks from the floor. You should hear the plates settle against the bar before the actual pull begins.
- Looking up: Cranking your neck back doesn’t help your back position and compresses your cervical spine. Pick a spot on the floor about 6 to 8 feet in front of you and keep your gaze there throughout the lift.
