The deadlift has a fearsome reputation — the lift most likely to "wreck your back," according to gym folklore. The reality is that a well-executed deadlift is one of the best things you can do for your back, and the pattern it trains is one you perform every time you pick something off the floor. What hurts people isn't the deadlift; it's a rounded spine, a load they weren't ready for, and ego. Here's how to do it properly.
Why deadlift?
Because it trains the hip hinge — bending at the hips to pick something up — which is arguably the most useful movement pattern in daily life, and one most people perform badly. It loads your entire posterior chain (glutes, hamstrings, back) plus your grip and core in a single movement, making it exceptionally efficient. Learning to hinge properly under load also teaches you how to lift things safely outside the gym, which is the real-world case made in functional fitness.
The setup
Most deadlift injuries are decided before the bar moves. Stand with the bar over your mid-foot, feet roughly hip-width. Hinge down by pushing your hips back and grip the bar just outside your legs. Now the critical part: pull your chest up and set your back flat, taking the slack out of the bar so there's tension before you lift. Your shoulders should sit roughly over or just in front of the bar, hips higher than your knees. Brace your core hard, as if bracing for impact. If your back rounds during setup, you've already lost the rep — reset.
The lift
- Push the floor away with your legs rather than yanking the bar with your back.
- Keep the bar close — it should travel up your shins and thighs, almost dragging. A bar that drifts forward dramatically increases the strain on your lower back.
- Hips and shoulders rise together. If your hips shoot up first, the lift becomes a rounded-back pull.
- Stand tall by driving your hips forward, finishing with the bar at your thighs. Don't lean back or overextend at the top.
- Lower it under control, hinging back down the same path.
The faults that matter
| Fault | Usually means |
|---|---|
| Rounded lower back | Too heavy, or poor setup — the main injury risk |
| Bar drifting away from you | Big increase in lower-back strain |
| Hips shooting up first | Legs not contributing; back doing the work |
| Jerking the bar off the floor | Slack not taken out before pulling |
Note what's not on that list: squatting the bar up, exact hip height, or one universally correct starting position. Those vary with limb length and proportions. A flat back and a close bar path are the non-negotiables.
Grip and stance variations
Grip is often the limiter before your back or legs are. A mixed grip (one palm forward, one back) or a hook grip lets you hold heavier loads, and straps have their place on top sets — though as covered in grip strength training, using straps on every set stops your grip ever developing. On stance, the conventional deadlift uses a roughly hip-width position; the sumo variation uses a much wider stance with hands inside the legs, which suits some builds better and reduces the forward lean. Neither is more "correct" — pick the one that lets you keep a flat back and a close bar. Trap-bar deadlifts are an excellent option for many people, since the handles at your sides make a neutral spine easier to maintain.
Progressing without hurting yourself
Start far lighter than you think you need to, and treat the first weeks as skill practice rather than strength testing. Add load gradually via progressive overload only once the pattern is solid, and stop a set the moment your back rounds — a rep with a rounded spine isn't worth the number. Warm up thoroughly beforehand, as in how to warm up before lifting, and address hip and hamstring mobility if you can't reach the bar with a flat back, which a mobility routine helps with. Because deadlifts are demanding, they also need genuine recovery — see deload weeks. And if you have an existing back issue, get proper guidance before deadlifting rather than working it out yourself; the principles in training around an injury apply.
Frequently asked questions
Are deadlifts bad for your back? Done with a flat back and appropriate load, deadlifts strengthen the back and hips rather than harming them. Injuries typically come from a rounded spine, a bar drifting forward, or lifting more than you're ready for — all technique and load issues, not the exercise itself.
Should I deadlift conventional or sumo? Whichever lets you maintain a flat back with the bar close, given your build. Sumo's wider stance reduces forward lean and suits some proportions; conventional suits others. Trap-bar deadlifts are also a very good option, especially for beginners.
Why does my lower back hurt after deadlifting? Commonly a rounded spine, a bar path drifting away from your body, hips rising before the shoulders, or simply too much weight. Reduce the load, film a set to check your back position, and if pain persists, get it assessed by a professional.
Do I need to lift heavy to benefit from deadlifts? No — the movement pattern and moderate progressive loading deliver most of the benefit. Building the hinge correctly with manageable weight is far more valuable than chasing a heavy number with poor form.
The bottom line
The deadlift trains the hip hinge you use every day, and it's safe when the spine stays flat and the bar stays close. Set up with tension before you pull, push the floor away, keep hips and shoulders rising together, and finish tall without leaning back. Round your back and the lift becomes the thing its reputation suggests. Start light, build the pattern, then add load — in that order.
Technique matters most inside a program that tells you when to add load and when to back off. The Adaptable Strength & Conditioning System ($19, reg. $29) programs the hinge pattern with variations and sensible progression, so you build strength without the injuries that come from guessing.
