The Deadlift: King of All Lifts

The deadlift is the single most effective exercise for building total-body strength. It trains the posterior chain (hamstrings, glutes, spinal erectors), grip, traps, lats, and core in one movement. It's also one of the simplest lifts conceptually — pick the bar up off the floor. Yet poor technique is rampant, even among experienced lifters, and the consequences range from stalled progress to serious back injuries.

If your deadlift numbers aren't moving up, or worse, if you're experiencing chronic low back pain from pulling, one or more of these five mistakes is almost certainly the culprit. Fixing them won't just protect your spine — it will unlock strength you didn't know you had.

Mistake #1: Rounding Your Lower Back

This is the most dangerous and most common deadlift error. When the lower back rounds under load, the intervertebral discs are subjected to extreme shear forces — the kind that cause herniated and bulging discs. Your spinal erectors can't produce force efficiently in a flexed position, which means you're both weaker and less safe.

Why it happens: Most often, lower back rounding occurs because the lifter is trying to pull a weight that's too heavy for their current strength, or because they fail to create tension before the bar leaves the floor. It also happens when the hips shoot up faster than the shoulders at the start of the pull (the "stripper deadlift").

How to fix it:

  • Brace hard before every rep: Take a deep breath into your belly (not your chest), brace your core as if someone is about to punch you in the stomach, and maintain this brace throughout the entire lift. This creates intra-abdominal pressure that supports the spine.
  • Pull the slack out of the bar: Before you pull the bar from the floor, squeeze the bar and create tension in your entire body. You should feel your lats engage, your hamstrings load, and your back tighten before the bar moves an inch.
  • Use a belt: A weightlifting belt gives your core something to brace against, increasing intra-abdominal pressure. It doesn't replace core strength — it enhances it. Use a belt for working sets above 80% of your max.
  • Lower the weight: If you can't maintain a neutral spine, the weight is too heavy. Drop to a weight you can pull with perfect form and build back up.

Mistake #2: Starting with Hips Too High or Too Low

Your hip position at the start of the deadlift is crucial — it determines which muscles are in the optimal position to contribute to the lift. Starting with hips too low turns the deadlift into a squat pattern, while starting with hips too high turns it into a stiff-leg deadlift. Neither is optimal for conventional pulling.

Hips too low (squatting the deadlift): When your hips drop below the optimal position, your shoulders end up behind the bar, your shins push the bar forward, and you end up pushing against the floor with your quads rather than pulling with your posterior chain. The bar drifts away from your body, and you lose power.

Hips too high (stiff-legging it): When your hips start too high, your hamstrings and glutes can't contribute optimally. All the load shifts to your lower back, and your hips shoot up even further at the start of the pull, creating a weak, back-dominant pull pattern.

Finding your optimal hip height: With the bar over mid-foot, grab the bar at shoulder width, then lower your hips until your shins gently touch the bar. Your shoulders should be slightly in front of the bar, your shoulder blades directly above the bar, and your arms vertical. This is your starting position — it varies based on your leverages (torso length, femur length, arm length), so it won't look identical to someone else's lift.

Mistake #3: Not Engaging Your Lats

The lats are critical deadlift muscles, yet most men don't actively engage them. Your lats keep the bar close to your body throughout the pull. When the bar drifts forward even an inch, the lever arm on your lower back increases dramatically, making the lift harder and more dangerous.

How to tell if your lats aren't engaged: If you have bruises on your shins from the bar scraping (good — the bar is close) but the bar drifts away from your thighs during the mid-pull, your lats aren't doing their job. If you hear the bar clang against your thighs on the way down, it means the bar took a forward path up and gravity is pulling it straight down past your body.

How to fix it:

  • "Protect your armpits" cue: Before you pull, imagine someone is trying to tickle your armpits and squeeze your lats to protect them. This engages the lats and locks the bar close to your body.
  • "Bend the bar around your shins" cue: Try to bend the bar around your legs before you pull. This activates the lats and creates full-body tension.
  • Straight-arm pulldowns: Add these as an accessory to strengthen the lat engagement pattern. 3 × 12-15 with a pause at the bottom to feel the lat contraction.

Mistake #4: Jerking the Bar Off the Floor

The deadlift starts from a dead stop — there's no stretch reflex to help you. When you yank the bar suddenly, several bad things happen: your hips shoot up, your back rounds, the bar drifts forward, and you lose the tight, braced position you need for a safe, strong pull. In worst-case scenarios, jerking the bar can also cause bicep tears (especially when using a mixed grip).

How to fix it: Treat the deadlift initiation as a gradual pressure build, not an explosive yank. Think "push the floor away" rather than "pull the bar up." Squeeze the bar progressively harder while driving your feet into the ground. The bar should separate from the floor smoothly, not with a violent jerk.

A helpful drill: pull the slack out of the bar until you hear or feel the barbell plates click against the top of the hole in the plates. Hold this position for a full second, then initiate the pull. This teaches patience at the start and eliminates the yank.

Mistake #5: Hyperextending at Lockout

You've seen it in every gym: the lifter completes the deadlift and then dramatically leans back, thrusting their hips forward and cranking their lower back into hyperextension. This is not a "full lockout" — it's a dangerous habit that compresses the posterior elements of the spine under heavy load and provides zero strength benefit.

What a proper lockout looks like: Stand tall with your hips fully extended, knees locked, and shoulders pulled back. Your body should form a straight vertical line from head to heel. Your glutes should be squeezed hard at the top to lock the hips into full extension. There should be no lean-back — your spine remains neutral throughout.

Why men hyperextend: Usually it's because they've seen powerlifters exaggerate the lockout in competition (to clearly demonstrate lockout to judges) or because they lack the glute strength to achieve full hip extension and compensate by leaning back through the lumbar spine.

The fix: Cue "squeeze your glutes" at the top rather than "lean back." If your glutes are firing properly, your hips will reach full extension without any lumbar hyperextension.

Bonus: The Setup Checklist

Run through this checklist before every single rep:

  • Bar over mid-foot (about 1 inch from shins)
  • Grip the bar at shoulder width (or slightly wider for larger men)
  • Drop hips until shins touch the bar
  • Big breath into the belly, brace hard
  • Engage lats ("protect your armpits")
  • Pull the slack out of the bar
  • Push the floor away — smooth, controlled initiation
  • Lock out with glutes, stand tall — no hyperextension

Key Takeaways

  • A neutral spine is non-negotiable. Brace hard, pull the slack out, and lower the weight if your back rounds.
  • Find your optimal hip height by letting your shins touch the bar with shoulders slightly in front of it.
  • Engage your lats to keep the bar close to your body throughout the entire pull.
  • Never jerk the bar off the floor — build tension gradually and "push the floor away."
  • Lock out by squeezing your glutes at the top, not by leaning back and hyperextending your spine.
