The single-leg deadlift is a powerful unilateral lower-body exercise that combines strength, balance, coordination, and hip stability in one movement. Unlike traditional deadlifts, this exercise requires you to perform a hip-hinge pattern while balancing primarily on one leg.
Whether you are trying to strengthen your glutes and hamstrings, improve balance, develop better hip control, or add variety to your lower-body workouts, the single-leg deadlift can be an excellent addition to your fitness routine.
It can be performed with body weight, dumbbells, kettlebells, resistance bands, or other forms of resistance. Beginners can start without weights and gradually increase resistance as their balance and technique improve.

What Is a Single-Leg Deadlift?
The single-leg deadlift, also commonly called the single-leg Romanian deadlift (single-leg RDL) when performed with a controlled hip-hinge and relatively small knee bend, is a unilateral exercise that trains one side of the body at a time.
The movement involves standing on one leg, pushing the hips backward, lowering the torso toward the floor, and extending the opposite leg behind the body. You then use the muscles of the standing leg and hip to return to an upright position.
The exercise places significant demands on the hamstrings, glutes, hip stabilizers, and core, while the ankle and foot muscles also contribute to maintaining balance.
Single-Leg Deadlift vs. Single-Leg Romanian Deadlift
The terms are sometimes used interchangeably, but there can be a technical distinction.
A traditional single-leg deadlift may involve more knee flexion and can be performed with a greater range of motion. A single-leg Romanian deadlift generally emphasizes a hip-hinge movement, with the standing knee remaining slightly bent while the hips travel backward.
For most recreational fitness purposes, the important priorities are controlled movement, a stable pelvis, neutral spinal alignment, and appropriate range of motion rather than obsessing over terminology.
How to Do a Single-Leg Deadlift With Proper Form
Learning the movement without weight is often the best starting point. Once you can control the exercise, you can gradually introduce resistance.
Step 1: Start in a Stable Standing Position
Stand upright with your feet approximately hip-width apart.
Keep your shoulders relaxed, chest naturally positioned, and abdominal muscles gently braced.
Shift your weight onto one leg.
Step 2: Slightly Bend the Standing Knee
Maintain a soft bend in the knee of your supporting leg.
Avoid locking the knee completely straight.
The knee should remain relatively stable while the movement primarily occurs at the hip.
Step 3: Push Your Hips Back
Begin the movement by driving your hips backward.
Think about reaching your hips toward the wall behind you rather than simply bending forward at the waist.
This hip-hinge pattern is one of the most important aspects of proper deadlift technique.
Step 4: Extend the Opposite Leg
As your torso moves forward, extend your non-working leg behind you.
Try to create a long line from your head through your torso and toward your elevated heel.
Keep the pelvis as square to the floor as possible instead of allowing the hips to rotate open.
Step 5: Lower Under Control
Continue lowering until you reach a comfortable range of motion.
You do not need to touch the floor.
Your ideal depth depends on your hamstring flexibility, hip mobility, balance, and ability to maintain good alignment.
Step 6: Drive Through the Standing Foot
Contract your glutes and hamstrings and push through the standing foot.
Bring your hips forward and return to the starting position.
Avoid using momentum to swing the lifted leg or jerk your torso upward.
Step 7: Repeat on the Other Side
Complete your repetitions on one side before switching legs, or alternate sides if that feels more natural.
Focus on performing every repetition with control rather than simply trying to reach a specific depth.
Single-Leg Deadlift Muscles Worked
The single-leg deadlift is primarily a posterior-chain exercise, meaning it emphasizes muscles located along the back of the hips and legs.
1. Hamstrings
The hamstrings work to control hip movement and contribute to extending the hip as you return to standing.
Because the exercise involves a loaded or unloaded hip hinge, you may feel a substantial stretch through the hamstrings during the lowering phase.
2. Gluteus Maximus
The gluteus maximus is a major hip-extensor muscle.
It contributes strongly when you reverse the movement and bring your hips forward to stand.
3. Gluteus Medius and Other Hip Stabilizers
Because you are balancing on one leg, the muscles surrounding the hip must help stabilize the pelvis.
This unilateral demand is one reason the exercise can feel considerably more challenging than a conventional bilateral hip hinge.
4. Core Muscles
Your abdominal and trunk muscles work to stabilize your torso and pelvis.
A strong brace can make it easier to maintain control instead of twisting or collapsing during the movement.
5. Lower-Leg and Foot Muscles
The muscles around the ankle and foot contribute to maintaining your base of support.
Small adjustments in the foot and ankle can occur as your body works to maintain balance.
Benefits of the Single-Leg Deadlift
1. Strengthens the Glutes and Hamstrings
One of the biggest reasons people perform single-leg deadlifts is to develop the posterior chain.
The movement combines hip extension and controlled hip hinging, making the glutes and hamstrings important contributors.
2. Improves Balance
Standing on one leg adds a balance component that is absent from traditional two-legged deadlifts.
You have to control your body while your center of mass shifts forward and backward.
Regular practice can help you become more comfortable controlling your body in a single-leg position.
3. Develops Hip Stability
The exercise challenges your ability to keep the pelvis controlled while one leg is lifted.
This makes it particularly useful for people who want to develop better unilateral lower-body control.
4. Builds Unilateral Strength
Training one side at a time can help you identify differences in strength, coordination, or balance between your legs.
Unilateral exercises are commonly used to address asymmetries and develop functional lower-body strength.
5. Reinforces the Hip-Hinge Pattern
Learning how to move from the hips rather than excessively bending through the lower back is an important strength-training skill.
The single-leg deadlift provides a relatively low-load way to practice this movement pattern.
6. Challenges Core Stability
Your core must help prevent unnecessary rotation as your torso moves forward and your opposite leg moves backward.
This makes the exercise more than simply a hamstring or glute movement.
7. Can Support Athletic Movement
Balance, hip stability, unilateral strength, and coordination are useful qualities for activities such as running, jumping, changing direction, and other sports movements.
The single-leg RDL has also been highlighted as a practical exercise for combining hamstring and glute strength with balance and hip control.
8. Requires Minimal Equipment
The bodyweight version requires no equipment.
Once your technique improves, a pair of dumbbells or a kettlebell can provide additional resistance without requiring a large home gym.
Common Single-Leg Deadlift Mistakes
Good technique matters more than lifting heavy weight.
Mistake 1: Rounding the Back
Allowing the spine to excessively round can make the movement less controlled.
Fix: Keep your torso braced and maintain a comfortable, neutral spinal position throughout the movement.
Mistake 2: Rotating the Hips Open
A common problem is allowing the pelvis to rotate outward as the back leg rises.
Fix: Imagine that both hip bones are headlights pointing toward the floor.
Mistake 3: Going Too Low
Many people assume that touching the floor means they performed a better repetition.
It doesn't.
If lowering farther causes your back to round or your hips to rotate, stop earlier.
Fix: Use the deepest range of motion you can control while maintaining good technique.
Mistake 4: Locking the Standing Knee
A completely locked knee can make the movement feel rigid and may make balance more difficult.
Fix: Keep a slight, comfortable bend in the supporting knee.
Mistake 5: Moving Too Quickly
Speed often causes people to lose their balance and rely on momentum.
Fix: Slow down the lowering phase and pause briefly when necessary.
Mistake 6: Using Too Much Weight
Heavy dumbbells can turn a controlled balance exercise into a struggle to stay upright.
Fix: Master the bodyweight movement first, then add resistance gradually.
Mistake 7: Letting the Knee Collapse Inward
The supporting knee should remain controlled rather than collapsing toward the body's midline.
Fix: Maintain active control through the foot, ankle, knee, and hip.
Mistake 8: Chasing Balance Instead of Technique
If you're constantly wobbling, the exercise may become more about staying upright than training the intended muscles.
Fix: Hold onto a wall, rack, or other stable support while learning the movement.
Single-Leg Deadlift for Beginners
If you're new to the exercise, don't immediately start with heavy dumbbells.
Beginner Progression
Level 1: Supported Single-Leg Hinge
Stand beside a wall or sturdy support and use one hand for balance.
Level 2: Bodyweight Single-Leg Deadlift
Perform the exercise without weights while focusing on hip control.
Level 3: Kickstand Deadlift
Keep the toes of the non-working leg lightly touching the floor behind you.
Level 4: Light Dumbbell Single-Leg Deadlift
Hold one light dumbbell and gradually increase resistance as your technique improves.
Level 5: Heavier Single-Leg Deadlift
Increase the load only when you can maintain balance, alignment, and controlled movement.
Beginners are generally better served by developing movement quality before increasing resistance.
Best Single-Leg Deadlift Variations
1. Bodyweight Single-Leg Deadlift
The simplest variation.
Best for: Beginners, warm-ups, balance practice, and technique development.
2. Dumbbell Single-Leg Deadlift
Hold one or two dumbbells while performing the movement.
Best for: Building strength while maintaining a manageable setup.
3. Contralateral Dumbbell Single-Leg Deadlift
Hold the dumbbell in the hand opposite the standing leg.
For example, stand on your right leg and hold the dumbbell in your left hand.
This variation can increase the stability challenge.
4. Ipsilateral Dumbbell Single-Leg Deadlift
Hold the weight in the same hand as the standing leg.
This changes the stability demands and can provide a useful progression.
5. Kettlebell Single-Leg Deadlift
A kettlebell can be held in one or both hands.
Best for: Home workouts, strength training, and functional fitness.
6. Supported Single-Leg Deadlift
Use a wall, rack, bench, or other stable object for assistance.
Best for: Beginners or anyone who wants to emphasize the hip-hinge pattern without making balance the limiting factor.
7. Kickstand or B-Stance Deadlift
The non-working foot remains lightly behind the working leg.
This provides additional stability while still emphasizing one side more than a conventional bilateral deadlift.
8. Single-Leg Deadlift to Row
Combine the lower-body hinge with an upper-body rowing movement.
Best for: Advanced exercisers who want a more complex full-body challenge.
How Many Single-Leg Deadlifts Should You Do?
The ideal number depends on your fitness level and training goals.
For Beginners
Try:
- 2–3 sets
- 6–10 repetitions per side
- Light or no resistance
- Controlled tempo
For Strength and Muscle Development
A practical approach may include:
- 3–4 sets
- 6–12 repetitions per side
- Moderate resistance
- Controlled repetitions
For Balance and Movement Control
Focus less on heavy loading and more on:
- Slow repetitions
- Stable foot position
- Controlled hip movement
- Consistent range of motion
Quality should take priority over quantity.
How to Make the Single-Leg Deadlift More Effective
Focus on the Hip Hinge
Don't think about simply "bending forward."
Think:
Hips back → torso forward → opposite leg back → hips forward.
This cue helps keep the movement centered around the hips.
Keep the Weight Close
If you're using a dumbbell or kettlebell, avoid letting it drift unnecessarily far away from your body.
Keeping resistance controlled can make the movement more efficient.
Use a Slow Eccentric Phase
Take approximately two to three seconds to lower yourself.
A slower descent can help you develop control and become more aware of your balance.
Keep Your Hips Square
Imagine your pelvis is a bowl filled with water.
Your goal is to prevent the imaginary water from spilling out as you hinge.
Stop Before Your Form Breaks
Your range of motion is only useful if you can control it.
You don't need to reach the floor to perform an effective repetition.
Single-Leg Deadlift vs. Traditional Deadlift
Both exercises train the posterior chain, but their demands are different.
| Feature | Single-Leg Deadlift | Traditional Deadlift |
|---|---|---|
| Stance | One leg | Two legs |
| Balance demand | High | Lower |
| Unilateral training | Yes | No |
| Main muscles | Glutes, hamstrings, core | Glutes, hamstrings, back, core |
| Stability demand | High | Moderate |
| Loading potential | Generally lower | Generally higher |
| Best for | Balance, unilateral control, hip stability | Overall strength and heavy loading |
Traditional deadlifts allow considerably more external loading, while unilateral variations add balance and side-to-side control demands.
Who Should Avoid or Modify the Exercise?
The single-leg deadlift can be modified for different fitness levels, but it isn't appropriate to push through pain.
If you have an existing injury, significant balance limitations, persistent back pain, or have been advised to avoid certain movements by a healthcare professional, seek individualized guidance before adding the exercise.
A supported version or a bilateral hip-hinge exercise may be a better starting point.
Stop the exercise if you experience sharp pain, unusual joint pain, dizziness, or symptoms that concern you.
Tips for Better Single-Leg Deadlift Balance
If balance is your biggest challenge, try these strategies:
- Practice barefoot or in stable footwear when appropriate.
- Keep your standing foot firmly connected to the floor.
- Look at a fixed point ahead of you.
- Slow down the movement.
- Reduce the range of motion.
- Use a wall for support.
- Practice bodyweight repetitions before adding resistance.
- Strengthen your hips and ankles with other unilateral exercises.
Remember, you don't need perfect balance immediately. Balance is a skill that can improve with repeated practice.

Frequently Asked Questions
Is the single-leg deadlift good for glutes?
Yes. The exercise strongly involves the gluteal muscles, particularly during the hip-extension phase as you return to standing.
Does the single-leg deadlift work the hamstrings?
Yes. The hamstrings are major contributors during the hip-hinge portion of the movement and help control the descent.
Is a single-leg deadlift good for balance?
Yes. Because you perform the exercise primarily on one leg, it requires balance, coordination, and control.
Can beginners do single-leg deadlifts?
Yes. Beginners should start with a supported or bodyweight version before progressing to weights.
Should I feel single-leg deadlifts in my lower back?
You may feel your lower back working as part of your trunk stabilization, but the exercise should not cause sharp or significant back pain. If your lower back is doing most of the work, review your hip-hinge technique and reduce the resistance or range of motion.
How often should I do single-leg deadlifts?
For most people, 1–3 sessions per week can fit comfortably into a balanced strength-training program, depending on the rest of the workout and recovery needs.
Should I use one dumbbell or two?
Both options work. One dumbbell can increase the stability challenge, while two dumbbells can make the movement feel more symmetrical and allow greater loading.
How far should I lower the weight?
Lower only as far as you can while maintaining control, a stable pelvis, and good spinal alignment. Depth is individual rather than a fixed requirement.
Final Thoughts
The single-leg deadlift is much more than a balance exercise. It combines unilateral strength, hip hinging, glute and hamstring development, core stability, coordination, and lower-body control.
The most important part is not how low you can go or how much weight you can lift. Good single-leg deadlift form comes first.
Start with your body weight, use support if necessary, practice a controlled hip hinge, and gradually increase resistance as your stability improves.
With consistent practice, the single-leg deadlift can become a valuable part of a well-rounded lower-body workout.
