What is the Deadlift?
The deadlift is a barbell pull from the floor: the bar starts over mid-foot, and your hips and knees extend together until you stand locked out. It trains the erector spinae isometrically under the heaviest load most lifters ever handle, while the upper traps hold the shoulder girdle down and the lats keep the bar tight against your legs.
The one cue that matters: Brace hard, push the floor away, and keep the bar dragging up your shins — never round your back.
Why the Deadlift is worth doing
- Every rep starts from a dead stop, so there is no rebound to borrow and no stretch reflex to hide behind
- A loaded bar hangs off your shoulder girdle for the whole set, which loads the trap slope harder than shrugging for reps does
- Grip, hips and erectors all finish at the same instant, so one heavy set of five costs more recovery than three sets of rows
- It sets the ceiling for everything else you pull, from rack pulls to heavy rows
How to do the Deadlift
- Set your mid-foot Stand with the bar over the middle of your feet, heels roughly hip-width, about an inch from your shins. When you bend to grip it, the bar must not roll forward.
- Drop the hips Take a grip just outside your legs and drop your hips until your shoulders sit slightly ahead of the bar. From the side your arms hang vertical; angled back means your hips are too low.
- Pull the slack out Before you drive, pull up until the plates rattle tight against the collars and your arms lock straight. Then take your breath and hold it.
- Push the floor away Drive through your whole foot and let the bar drag up your shins. Hips and shoulders rise at the same rate, because the instant your hips lead, the bar swings away and the pull dies.
- Stand tall to finish Lock out by squeezing your glutes and standing straight. Do not lean back or add a shrug; the traps have been working since the bar left the floor.
- Reverse and reset Push your hips back, keep the bar on your thighs until it clears your knees, then bend and set it down. Let it settle, re-brace, and end the set on the rep after the bar stops touching your shins.
Muscles worked
The Erectors (erector spinae) do the defining work here, and they do it without changing length. From the instant the plates break the floor to lockout they hold your spine at one angle against a load whose only job is to fold you forward.
The Upper Traps (trapezius, upper) never contract to move anything in a deadlift. They hold, because a bar hanging from straight arms drags the shoulder girdle down for as long as you keep hold of it, which is why heavy pullers carry a visible slope from neck to shoulder without ever programming a shrug.
The Lats (latissimus dorsi) are what keeps the bar close. Shoulder extension pins it against your shins and thighs so it tracks straight up over mid-foot, and a bar two inches out in front is a longer lever on your hips than most people can finish.

Form tips
- Bar path, not bar height. The bar should trace one vertical line from the floor to your hips. Anything that pushes it forward, a start over your toes or hips that rise early, adds lever arm you then have to pay for.
- Shoulders ahead of the bar. At the start your shoulders sit just in front of the bar, never behind it. That is the only position from which the lats can hold the bar into your legs.
- Bar speed ends the set. Watch how fast the plates leave the floor. When a rep is visibly slower than the one before it, the next one will be a different exercise, so stop there instead of grinding.
Common mistakes
- Hips shooting up first
- The bar stays on the floor while your hips rise, so you finish the pull from a stiff-legged position at the worst hip angle. Think about pushing your feet down through the floor rather than lifting your chest.
- Jerking a loose bar
- Yanking before the slack is out means the plates move before your back is tight, so the first inch happens in a position you did not choose. Pull the bar into the collars, feel the tension, then drive.
- Bouncing touch-and-go reps
- Letting the plates rebound turns a dead-stop lift into a rhythm drill and hides the position you are actually weak in. Set it down, let it stop moving, and start each rep from zero.
Sets, reps and where it fits
Put it first or leave it out. BackMaxx runs 3 sets of 4–6, and those reps are only honest when the bar is the first thing you touch after warming up. Rows and pulldowns afterwards will feel heavier than usual, and that is the price of pulling from the floor.
Progress with load and leave the reps alone. When all three sets of 6 move at the same speed, add a small jump and drop back to 4s. The erectors recover slowly, so keep one heavy floor pull a week; if you want a second hinge day, run Romanian deadlifts at half the weight and stop them short of the floor. Then watch what the Lower Back line does in your Back Score before you add another heavy day.
No barbell? Do this instead
Without a barbell, the dumbbell sumo deadlift keeps the two things that define this lift, a floor start and a dead stop, using one dumbbell stood on end between your feet.
What goes missing is the top end. A single dumbbell caps out far below a loaded bar, and you lose the shin drag that holds the load over mid-foot, so run it at 10–12 reps and treat it as hinge volume.
Variations and similar exercises
- Sumo Deadlift
- A wide stance with the hands inside the knees shortens the distance the bar travels, so pick it if your hips open easily and your back angle fails first.
- Trap Bar Deadlift
- The handles sit beside you instead of in front, which cuts the lever arm at the hip and lets you pull heavy with a more upright torso.
- Rack Pull
- Starting at knee height removes the hardest inches off the floor and overloads the top half, which is where the traps and lats do most of their work.

Frequently asked questions
Is the deadlift a back exercise or a leg exercise?
Both, and BackMaxx files it under Lower Back because that is the part it visibly changes. Your hips and knees produce the movement while your erectors hold your torso rigid, which is a back job even though nothing in your back shortens. The upper traps and lats work isometrically for the whole rep too.
How often should you deadlift?
Once a week of heavy floor pulling is enough for almost everyone. The erectors are slow to recover, and a hard set of five leaves them loaded for days in a way a set of rows does not. If you want more hinging, add a lighter session with a shorter range instead of a second heavy day.
Do deadlifts build traps?
They build the upper traps through holding time rather than shrugging. Every rep hangs a heavy bar off your shoulder girdle and the trapezius resists being dragged down for the length of the set. That is why heavy pullers develop the neck-to-shoulder slope without training it directly, and why grip usually gives out first.
Should the Deadlift be in your plan?
BackMaxx scores your lower back from one photo and builds the week around whatever is lagging — so the Deadlift only shows up when it is the right call.
