Barbell Single Leg Deadlift
The Barbell Single Leg Deadlift is a compound movement that trains the hamstrings with help from glutes, adductors, lower back, quadriceps and calves. This guide covers the setup, the execution, the mistakes worth fixing early, and how to program it.
The hip hinge is how you pick things up: hips travel back, the torso folds forward, and the load lands on the hamstrings through a long stretch. It is the single most transferable strength pattern there is, and the one most often done with a rounded back.
Who it is for. Everyone, but the loading has to be earned — learn the pattern light before it gets heavy. Place it first or second in a lower-body or pull session.
Muscles worked
The prime mover here is the hamstrings, with glutes, adductors, lower back, quadriceps and calves assisting — which is why this movement earns its place as more than a single-muscle exercise.

How to do it
- Stand with your feet about hip-width and your weight over the middle of the foot, holding a barbell.
- Set your back flat, pull your shoulder blades down, and brace hard — the brace is what protects your spine.
- Soften the knees slightly. The hinge is a hip movement, not a squat.
- Push your hips straight back and let your torso fold forward, keeping the load tight against your legs.
- Go down until you feel a strong stretch in the hamstrings, stopping the moment your lower back starts to round.
- Drive your hips forward to stand tall, squeezing your glutes at the top without leaning back.
Breathing. Breathe in and brace at the top, hold through the rep, and breathe out at lockout. Re-brace before each rep rather than breathing at the bottom.
Form cues that matter
- Hips back, not down — the knees barely move.
- Keep the load dragging up your legs the whole way.
- Finish by standing tall, not by hyperextending.
- Rounding the lower back as you reach the bottom
- Turning it into a squat by bending the knees
Common mistakes
| The mistake | Do this instead |
|---|---|
| Rounding the lower back as you reach the bottom | Shorten the range to where you can hold a flat back, and rebuild depth as your hamstring flexibility improves. |
| Turning it into a squat by bending the knees | Set the knee angle at the start and hold it — only the hips should move. |
| Letting the load drift away from your body | Actively pull it back into your legs; a load that drifts forward multiplies the stress on your spine. |
What makes this variation different
The Barbell Single Leg Deadlift is a specific version of this movement, and the details in its name change how it should be performed.
- A barbell lets you load more weight than anything else and add it in small increments, which makes it the best tool for long-term strength progress. It also forces both sides to work together, so a stronger side can cover for a weaker one.
- Training one side at a time exposes any strength difference between your sides and forces the midsection to resist being pulled out of position. Always start the set with your weaker side and match the stronger side to it.

How to progress
Add weight before you add reps. Work at the top of your rep range for two sessions in a row with clean technique, then put the smallest increment available on the Barbell Single Leg Deadlift and build back up. Small, boring jumps beat big ones.

Key takeaways
- Hips back, not down — the knees barely move.
- Keep the load dragging up your legs the whole way.
- Work in the 6-12 rep range for muscle growth, leaving a rep or two in reserve on most sets.
- Full range of motion on the Barbell Single Leg Deadlift matters more than the weight on it.
- Progress gradually and keep technique identical as the load goes up.

FAQ
What muscles does the Barbell Single Leg Deadlift work?
It works the hamstrings as the prime mover, with glutes, adductors, lower back, quadriceps and calves assisting. The midsection also works throughout to keep you stable.
How many sets and reps should I do on the Barbell Single Leg Deadlift?
Three to four working sets of 6-12 reps suits most people training for muscle growth, leaving one or two reps in reserve. Across all the exercises that train this muscle, 8-16 hard sets a week is a productive range.
Is the Barbell Single Leg Deadlift good for beginners?
Yes, provided you start light enough to own the technique. Spend the first few weeks on the movement itself with a load you could do several more reps with, and add weight only once the pattern is automatic.
What can I do instead of the Barbell Single Leg Deadlift?
Barbell Deadlift, Barbell Romanian Deadlift and Barbell Sumo Deadlift all train the hamstrings in a similar way, so any of them works as a substitute when the equipment is taken or you want to rotate the stimulus.
What equipment do I need for the Barbell Single Leg Deadlift?
This version uses a barbell. The pattern matters more than the tool, though — the alternatives above cover the same movement with whatever you have available.
