Barbell Deadlift
The barbell deadlift is a compound lift where you pull a loaded barbell from the floor to a standing position with hips and knees fully extended. It trains the glutes, hamstrings, quadriceps and spinal erectors, with the lats and traps holding the bar and spine in place. Most lifters train it for 3–5 sets of 3–6 reps.

What muscles does the barbell deadlift work?
Primary movers
- Gluteus maximus
- Hamstrings
- Spinal erectors
Assisting muscles
- Quadriceps
- Latissimus dorsi
- Trapezius
- Forearms
- Adductor magnus
The deadlift is fundamentally a hip extension exercise. The glutes and hamstrings drive the hips from a flexed position to lockout, and they do the majority of the work through the middle and top of the lift.
The quadriceps matter more than the deadlift's reputation suggests, but only off the floor. The knees are bent at the start and straighten during the first few inches, so the quads contribute to breaking the bar off the ground and then largely stop mattering.
The spinal erectors work isometrically and extremely hard. Their job is to stop your spine flexing while your hips move — they are not extending your back, they are refusing to let it round. This is the deadlift's defining demand and the reason it is so fatiguing.
The lats do not lift the bar, but they keep it close to your body. A bar that drifts forward lengthens the lever arm on your spine dramatically. Engaging the lats is the difference between a deadlift that feels connected and one that feels like a fight.
Your grip and traps hold the entire load. For many lifters, grip fails before the posterior chain does, which is why straps and mixed grips exist — and why some direct grip work is worthwhile.
How to do the barbell deadlift
Setup
- 1
Stand with your feet roughly hip-width apart, with the bar directly over your mid-foot. The bar should be about an inch from your shins.
- 2
Hinge at the hips and bend the knees to reach the bar, gripping just outside your legs.
- 3
Use a double overhand grip for lighter sets; switch to a mixed grip, hook grip or straps when grip becomes the limiting factor.
- 4
Drop your hips until your shins touch the bar. Your shoulders should sit slightly ahead of the bar, not behind it.
- 5
Pull your chest up and set a neutral spine from head to tailbone — flat, not arched, not rounded.
- 6
Engage your lats by thinking about squeezing oranges in your armpits, and take the slack out of the bar until you hear or feel it click against the plates.
Execution
- 1
Take a big breath into your belly and brace hard against it.
- 2
Push the floor away with your legs rather than yanking the bar upward. The bar should rise as your knees straighten.
- 3
Keep the bar in contact with or grazing your legs the whole way up.
- 4
Once the bar passes your knees, drive your hips forward into the bar to finish the lift.
- 5
Lock out standing tall with hips and knees extended. Do not lean back, hyperextend your spine or shrug at the top.
- 6
Reverse the path to lower: push the hips back first, then bend the knees once the bar passes them. Control it rather than dropping it.
Common barbell deadlift mistakes
Rounding the lower back
The lumbar spine flexes under load, usually as the bar breaks the floor. This is where most deadlift injuries come from, and it is almost always a sign that the weight exceeds what your bracing can hold.
The fix: Reduce the load until you can hold a neutral spine for every rep. Set your chest and brace before you pull, and film from the side — this fault is very hard to feel and very easy to see.
Hips shooting up first
The hips rise faster than the shoulders, so the bar leaves the floor with your back already at a steep angle. The lift becomes a stiff-leg deadlift with a much longer lever on your spine.
The fix: Cue pushing the floor away with your legs and keeping your chest up as the bar breaks. If the hips still shoot up, your starting hip position was probably too low for your leverages.
Letting the bar drift away from the body
The bar swings forward of mid-foot, dramatically increasing the load on the lower back and making lockout much harder.
The fix: Engage the lats before you pull and think about dragging the bar up your legs. Some lifters wear long socks because the bar should be close enough to graze the shins.
Jerking the bar off the floor
Yanking without first taking the slack out of the bar. The sudden load spike on a spine that is not yet braced is a common way to tweak a back.
The fix: Pull gently until the bar makes contact with the plate collars, feel the tension build, then pull. The start should feel like a heavy press, not a snatch.
Hyperextending at lockout
Leaning back and pushing the hips forward past neutral at the top. It adds nothing and compresses the lumbar spine in an extended position.
The fix: Finish standing tall and neutral — hips under shoulders, glutes squeezed, ribs down. That is a complete rep.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Strength | 3–5 | 1–5 | 82–92% 1RM | 3–5 min |
| Hypertrophy | 3–4 | 5–8 | 70–80% 1RM | 3 min |
| Beginner / technique | 3 | 5 | Light, 3+ RIR | 2–3 min |
The deadlift is the most systemically fatiguing lift most people do, and total weekly volume needs to be lower than for squats or presses. Once or twice a week is plenty, and many strong lifters deadlift heavy only once. Because fatigue accumulates faster than technique degrades, deadlifting to failure is a bad idea — leave one to three reps in reserve on almost every set.
Barbell Deadlift variations and alternatives
Trap Bar Deadlift
EasierThe handles sit beside you rather than in front, which shortens the lever on your spine and lets you keep a more upright torso. Easier to learn and much kinder to the lower back.
Romanian Deadlift
EasierStarts from the top and never touches the floor. Targets the hamstrings and glutes specifically without the fatigue cost of pulling from the ground.
Sumo Deadlift
AlternativeA wide stance with hands inside the legs. Shortens the range of motion and keeps the torso more upright, shifting work toward the quads and adductors.
Deficit Deadlift
HarderStanding on a low platform increases the range and makes the start much harder. Useful if you are weak off the floor, but only once your technique holds up under load.
Rack Pull
AlternativeStarting from pins above the knee lets you overload the lockout with much less fatigue. Good accessory work, not a replacement for the full lift.
Frequently asked questions
Is the deadlift bad for your back?
No — done properly it is one of the best exercises for building a resilient lower back, and the spinal erectors adapt strongly to the isometric demand. Deadlift injuries are overwhelmingly associated with lumbar rounding under load, loads that outpace technique, and pulling while already fatigued. The lift is not inherently dangerous; loading it faster than you can brace it is.
Conventional or sumo deadlift — which is better?
Neither is universally better. Sumo shortens the range of motion and keeps the torso more upright, which suits lifters with long torsos or those wanting less lower-back stress. Conventional suits lifters with longer arms and strong posterior chains. Both are legal in powerlifting and both build strength — pick the one that feels stronger and lets you progress.
Should I use straps for deadlifts?
Yes, once grip is the limiting factor on your heaviest sets. There is no benefit to letting your forearms cap how much your legs and back get trained. Do your lighter warm-up sets double overhand without straps so your grip still gets some work, and use straps when the load exceeds what you can hold.
How often should I deadlift?
Once or twice a week for most people. The deadlift generates more systemic fatigue per set than almost any other lift, so weekly volume should be lower than for squats. Many strong lifters pull heavy once a week and use Romanian deadlifts or rack pulls as a lighter second exposure.
Should I drop the bar or lower it?
Lower it under control if you can do so without your form breaking down. The lowering phase contributes to muscle growth and to reinforcing the movement pattern. On very heavy singles, or in gyms with bumper plates and platforms, controlled dropping is acceptable and reduces fatigue. Never drop a bar with iron plates on a standard floor.
