What muscles does the dumbbell hip hinge work?

The hamstrings do the work, the glutes assist as you stand up, and the lower back holds your spine in position without moving it. If your lower back is what feels tired, it has been asked to do more than hold.

How is a hip hinge different from a squat?

The hips. A squat sends them down and bends the knees a lot. A hinge sends them back and barely bends the knees. You feel a squat in the front of the thighs and a hinge as a stretch in the back of them.

How far down should you hinge?

As far as your hips will travel while your back stays flat, which for most people is somewhere between mid-shin and just below the knee. It varies a lot between people. Reaching for the floor past that point means bending the back, not the hips.

Should your knees be locked during a hip hinge?

No. A soft, slightly unlocked knee that stays at the same angle throughout is what you want. Locked knees make the position harsher than it needs to be, and knees that bend and straighten turn it into a squat.

Is the hip hinge the same as a Romanian deadlift?

The Romanian deadlift is a hinge done with a loaded bar, so the pattern is the same. This version with light dumbbells is where most people learn what the pattern feels like before the weight makes mistakes expensive.

Dumbbell hip hinge

Also called Dumbbell hinge, Stiff leg hinge, Hip hinge pattern, Dumbbell Romanian deadlift, Dumbbell RDL.

The short answer

The hip hinge pushes your hips backward while your torso tips forward, with the knees barely bending. Your hamstrings do the work, your glutes assist in bringing you upright, and your lower back holds the position rather than moving. It is the pattern underneath the Romanian deadlift and the deadlift, and telling it apart from a squat is the one thing worth getting right here.

How to do it

Step oneStand with feet hip-width apart holding a dumbbell in each hand at your sides.
Step twoKeep a slight bend in your knees and your back flat throughout the movement.
Step threeHinge at the hips and push them back as you lower your torso toward the floor.
Step fourLower until you feel a stretch in your hamstrings, then drive your hips forward to return to standing.

What usually goes wrong

Each starts with what you would notice.

Your knees bend a long way and you feel it in the front of your thighs.

WhyYou are squatting. The hips are dropping down instead of traveling back, so the knee takes the movement and the hamstrings never lengthen.

FixSet a soft knee bend at the start and refuse to change it. Push the hips toward the wall behind you and let the torso tip because they went, not because you bent forward.

Your back rounds near the bottom.

WhyThe hips have run out of travel but you are still going down, so the spine bends to make up the rest.

FixStop where your hips stop. That point is usually somewhere between mid-shin and just below the knee, and it is different for different people.

You are trying to touch the dumbbells to the floor.

WhyYou are treating the floor as the target. How far you can hinge is set by how far your hamstrings will lengthen, not by the length of your arms.

FixIgnore the dumbbells and watch your hips. When the stretch in the back of your thighs stops increasing, that is the bottom of your hinge.

You finish each rep leaning backward with the hips pushed forward.

WhyOvershooting the top. Standing upright is where the movement ends, and going past it just bends the lower back the other way.

FixSqueeze the glutes and stop when you are standing straight, with your ribs over your hips.

The dumbbells swing out away from your legs on the way down.

WhyThe further the weight sits from your hips, the longer the lever your lower back has to hold. It gets heavy quickly.

FixKeep the dumbbells brushing close to your thighs and shins the whole way down and back up.

Hinge or squat

These are the two ways of bending down and almost every lower body movement is one of them. Confusing them is the most common reason a hinge feels wrong.

In a squat your hips travel downward, your knees bend a lot, and your thighs do most of the work. In a hinge your hips travel backward, your knees barely bend, and the back of your legs does the work. Everything else follows from that one difference.

The check is simple. If you feel it in the front of your thighs, you squatted. If you feel a stretch in the back of them, you hinged. Nothing about the weight in your hands changes which one you did.

This matters beyond this page. The Romanian deadlift, the deadlift, the good morning and the kettlebell swing are all hinges. If the pattern is unclear here, it will be unclear there too, with a lot more weight involved.

What it is for

The dumbbell hip hinge is a fundamental movement pattern exercise targeting the hamstrings and posterior chain. It teaches proper hip hinge mechanics, which are foundational for movements like the deadlift and Romanian deadlift.
