Dumbbell Single-Leg Deadlift
Overview
- Primary Focus:
- Upper legs, glutes, and back.
- Equipment:
- Dumbbell.
- Difficulty:
- Intermediate.
General Information
Dumbbell Single-Leg Deadlift is a unilateral compound exercise that primarily targets the upper legs, with significant involvement of the posterior chain. The lifter stands on one leg while hinging at the hip and lowering a dumbbell toward the floor, with the non-working leg extending behind the body as a counterbalance. This creates a strong stretch and contraction through the hamstrings and glutes of the stance leg.
The single-leg stance introduces a substantial balance and stability challenge that recruits the hip stabilizers, particularly the gluteus medius and deep hip rotators. This makes the exercise valuable not only for building posterior chain strength but also for improving proprioception and reducing the risk of lower-body injuries common in running and field sports.
The Dumbbell Single-Leg Deadlift complements bilateral hip hinge variations such as the Barbell Romanian Deadlift and Dumbbell Romanian Deadlift. It also pairs well with unilateral knee-dominant exercises like Dumbbell Lunges or Step-Ups for a balanced lower-body session.
The dumbbell can be held in the hand opposite the working leg (contralateral) to create a cross-body stabilization demand, or in the same-side hand (ipsilateral) to increase the challenge on the lateral hip stabilizers. Both variations are effective, though the contralateral grip is more common.

Instructions
- Hold a dumbbell in one hand and stand with your feet hip-width apart.
- Shift your weight onto the leg opposite the loaded hand and soften the knee slightly.
- Begin the movement by hinging at the hip, pushing the hips backward while keeping the spine neutral.
- As you hinge forward, allow the non-working leg to extend straight behind you, forming a line with the torso.
- Lower the dumbbell toward the floor, keeping it close to the stance leg throughout the descent.
- Continue hinging until your torso and rear leg are approximately parallel to the floor or until you feel a strong stretch in the hamstring of the stance leg.
- Pause briefly at the bottom while maintaining a flat back and level hips.
- Drive through the stance foot and squeeze the glute to reverse the movement, bringing the torso back to upright.
- Return the rear leg to the starting position and stand tall before beginning the next rep.
- Complete all prescribed reps on one side before switching to the other leg.
Common Mistakes
Injuries
Dumbbell Single-Leg Deadlift is a medium risk exercise when performed with proper technique. The primary concern is the lower back, as rounding the spine under load during the hinge places shear forces on the lumbar discs. Maintaining a neutral spine throughout the movement is essential. Those with a history of lumbar disc injuries should start with very light loads and limited range of motion.
The balance requirement means that loss of control can lead to awkward loading of the hip or knee. If balance is a significant challenge, performing the exercise near a wall or rack for occasional support can reduce injury risk during the learning phase.
Hamstring strains are possible if the lifter uses excessive weight or forces range of motion beyond their current flexibility. Only descend as far as you can while maintaining proper hip hinge mechanics and a neutral spine. Over time, flexibility and range of motion will improve naturally.
Frequently Asked Questions
- Q: Which hand should hold the dumbbell?
The most common setup is to hold the dumbbell in the hand opposite the stance leg (contralateral grip). This creates a natural cross-body stabilization demand. Holding it on the same side is also valid and shifts the challenge toward the lateral hip stabilizers.
- Q: How is this different from a Romanian Deadlift?
The Dumbbell Romanian Deadlift is performed on both legs, which allows heavier loads but removes the balance and hip stability component. The single-leg version uses lighter weight but develops unilateral strength and proprioception.
- Q: Can I hold two dumbbells instead of one?
Yes, holding a dumbbell in each hand is a common variation. It allows for more total load but reduces the anti-rotation demand on the core compared to a single dumbbell.
- Q: I keep losing my balance. What can I do?
Start by lightly touching a wall or rack with your free hand for stability. You can also reduce the range of motion and gradually increase it as your balance improves. Performing the exercise barefoot on a firm surface may also help.
