Deadlifts are considered an essential exercise for a reason. They train your body to pick up things off the floor—a skill that’s invaluable in daily life. That’s why there are almost too many variations of the deadlift to count.

One of those is the single-leg deadlift, “an exercise that gives you a huge bang for your buck,” says Schuyler Archambault, physical therapist and owner of Arch Physical Therapy and Fitness. Although this strength exercise comes with plenty of benefits, it demands a lot in return; it’s easy to mess up the hip hinge (the movement pattern at the heart of the exercise), and balancing on one leg is no easy feat. Luckily, there are plenty of ways to modify, so you can reap the rewards—and without falling over. 

Here’s your guide to single-leg deadlifts, including how to do them properly.

What Are Single-Leg Deadlifts?

Single-leg deadlifts are exactly what they sound like: a deadlift done on one leg at a time. The non-working leg lifts up behind you as a counterbalance, so you end up in a sort of Warrior 3 shape. You can do them with just your body weight or with weight in either or both hands, which you lower along your standing leg.

The Differences Between RDLs and Single-Leg Deadlifts

Romanian deadlifts (aka RDLs) are bilateral, meaning they work both legs at the same time, says Peloton instructor Jess Sims. Meanwhile, single-leg deadlifts are, naturally, done on a single leg. Compared to single-leg deadlifts, you’ll likely be able to lift heavier with RDLs, since they don’t have a balance component, Archambault says. However, that lack of a balance challenge means RDLs don’t work your foot, ankle, and hip stabilizer muscles as much as single-leg deadlifts do.

Single-Leg Deadlifts vs. Staggered-Stance Deadlifts

With staggered-stance deadlifts (aka split-stance or kickstand deadlifts), you stand with the majority of your weight on one leg, but you keep the other foot on the ground just behind you for balance. It’s a great single-leg deadlift modification; there’s less of a balance challenge, but you still work your leg and core muscles in a similar way. “Staggered deadlifts require you to maintain balance while performing the movement, so your core is more involved, [just like] in the single-leg deadlift,” Jess says.

Muscles Targeted By Single-Leg Deadlifts

“Single-leg deadlifts primarily work your hamstrings and glutes, but also strengthen your ankles and calves as you work to stabilize yourself during the movement,” Jess says. Your core, back extensors, and hip stabilizers are also key players, Archambault says—especially your gluteus medius and gluteus minimus, two glute muscles on the side of your hips. “Both are used to stabilize the pelvis and maintain your knee position,” Archambault says. Research shows that single-leg deadlifts are particularly great at activating the biceps femoris (a hamstring muscle) and the glute medius compared to regular deadlifts.

The Benefits of Single-Leg Deadlifts

Single-leg deadlifts may seem like a move for advanced athletes, but it drills important skills for anyone who wants to move well through life. “Single-leg deadlifts are great for the general population to work on balancing and picking up objects from the floor,” Archambault says. Because they strengthen foot, ankle, and hip stabilizers, she often uses them with clients recovering from foot, ankle, knee, and hip injuries.

They’re also valuable because they’re a unilateral exercise, meaning they work one side of the body at a time. Unilateral work is really important to include in your workout routine because it exposes weaknesses and where your body might be overcompensating—that is, “where your stronger side essentially picks up the slack for the weaker side and then is often overworked and prone to injury,” Jess explains.

Runners, especially, have a lot to gain from adding single-leg deadlifts to their routine. “When you run, you’re never on both legs at the same time, so it’s crucial to work the legs individually,” Jess says. Ditto for anyone who plays sports with any sort of single-leg demands, Archambault says, from soccer and pickleball to skiing.

How to Do a Single-Leg Deadlift

Here’s how to master the bodyweight single-leg deadlift, with step-by-step instructions courtesy of Jess.

  1. Stand with your feet hip-width apart. Shift your weight into your right leg, with a soft bend in the right knee.

  2. Kick your left foot toward the wall behind you. Keep your left foot flexed and your hips and shoulders square to the floor. As you do this, reach your hands forward toward the wall in front of you until your upper body and left leg are in one line, about parallel to the floor.

  3. Lower your left foot and lift your chest to return to standing, arms by your sides. (Optional: Add a knee drive with your left leg, as shown above, bringing your right arm forward in a running motion.)

  4. That’s one rep. Do 3 sets of 8–12 reps on each side.

4 Form Tips for Single-Leg Deadlifts

First, master the hinge. “Make sure you learn how to perform a hip hinge or Romanian deadlift before trying the single-leg variation,” Archambault says. This ensures you’re not arching or rounding your back, but moving at the hip joint—which you’ll need to do to recruit your glutes and hamstrings effectively.

Stay square. As you hinge forward, keep your shoulders, ribs, and hips parallel to the floor, not allowing your hip to rotate open, Archambault says. If your hips are tilting because you’re having trouble balancing, try keeping your gaze fixed on one point on the floor about one or two feet ahead of you. Alternatively, you can place one hand onto a bench or wall to support, she says. 

Start small. You can reap the benefits of a single-leg deadlift even if you’re not getting your leg up to parallel. While you’re improving your balance and getting stronger, “start with a shortened range of motion to get used to where your body is in space and gradually increase,” Archambault says.

Adjust your depth accordingly. “When performing single-leg deadlifts, you want to pause and come back up at either the point where you can no longer maintain balance and need to use your other foot for support or when you hit the lowest position you can while keeping your back flat,” Archambault says. If you’re using weights, start with a goal of lowering the weight to your knee, and aim to reach mid-shin once you’re familiar with the move.

What Equipment Can You Use for Single-Leg Deadlifts?

Great news: When it comes to single-leg deadlifts, you can use pretty much any equipment you have on hand. That includes: 

  • Your Body Weight: Bodyweight single-leg deadlifts, as outlined above, are great for beginners or as a dynamic warm-up exercise.

  • Resistance Band: Loop one side or end of a resistance band under the foot of your standing leg, and hold onto the other side with one or both hands. You can also try anchoring a band to a wall, door, or railing in front of you.

  • Dumbbell(s): As shown below, you can do single-leg deadlifts with one or two dumbbells.

  • Kettlebell(s): If you’re a fan of kettlebell training, go ahead and give a kettlebell single-leg deadlift a try, either holding a single bell in the hand on the side of your lifted leg or two kettlebells, one in each hand.

  • Barbell: You can do single-leg deadlifts with a barbell, too—check out the demonstration above by Peloton instructor Adrian Williams.

  • Cable Machine: If you’re in the gym, you can also do single-leg deadlifts with a cable machine. Set the anchor point on the lowest possible setting, and hold the handle on the same side as the leg that’s extending backward.

Single-Leg Deadlifts: Variations and Modifications

To tweak single-leg deadlifts to make them easier or harder, you can: keep a foot on the floor; use two dumbbells; use one dumbbell in either hand; and even hold the bottom position and move the dumbbell from one hand to the other to create more instability so your hamstrings, calves, ankles, and feet have to work harder to maintain balance, Jess says. Try these three variations, listed in order of increasing difficulty:

Kickstand or Staggered-Stance Deadlift

As mentioned above, the staggered-stance or kickstand deadlift is a great modification of the single-leg deadlift if you’re having trouble with balance.

  1. Start standing with your feet hip-width apart. Shift your weight into your right leg, keeping it softly bent. Place your left foot just behind you, balancing on your toes. Hold a dumbbell in each hand in front of your hips, palms facing your body.

  2. With your core engaged, back flat, and neck long, hinge at your hips to push your glutes backward. Bend your right knee and lower the dumbbells along your right leg until the dumbbells are at shin height, or until you feel a stretch in your right hamstring.

  3. Pause, then exhale as you squeeze your right glute and lift your chest to return to start.

  4. Do 3 sets of 8–12 reps on each side.

To level up, try using two dumbbells, one in each hand, Jess says. 

  1. Stand with your feet hip-width apart. Shift your weight into your right leg, keeping it softly bent. Hold a dumbbell in each hand in front of your hips, palms facing your body.

  2. With your core engaged, lower the dumbbells along your right leg, lifting your left leg up behind you, keeping your hips square to the floor. 

  3. Stop when the dumbbells are at shin height, until you feel a stretch in your right hamstring, or your torso and left leg are parallel to the floor.

  4. Pause, then exhale as you squeeze your right glute, lower your left leg, and lift your chest and the dumbbells to return to start, keeping the weights close to your body at all times. 

  5. Do 3 sets of 8–12 reps on each side.

Contralateral Single-Leg Deadlift

Contralateral single-leg deadlifts—when you hold a weight in the hand opposite your standing leg—have been shown to activate the glutes more than when you put weight in your other hand, Archambault says. (Optional: Add a knee drive at the top, as shown above, resting the dumbbell on top of your left thigh as you drive it toward your chest.) 

  1. Start standing with your feet hip-width apart. Shift your weight into your right leg, keeping it softly bent. Hold a dumbbell in the left hand in front of your pelvis, palm facing your body. Extend your right arm out to the side for balance.

  2. With your core engaged, lower the dumbbell along your right leg, lifting your left leg up behind you, keeping your hips square to the floor. 

  3. Stop when the dumbbell is at shin height, until you feel a stretch in your right hamstring, or your torso and left leg are parallel to the floor.

  4. Pause, then exhale as you squeeze your right glute, lower your left leg, and lift your chest and the dumbbell to return to start, keeping the weight close to your body at all times. 

  5. Do 3 sets of 8–12 reps on each side.

Mistakes to Avoid When Doing Single-Leg Deadlifts

A common mistake people make is doing single-leg deadlifts before they’re ready, Jess says. You need to have a certain level of flexibility to get in and out of this position properly, without rounding your back. Drill traditional RDLs, staggered-stance deadlifts, and single-leg deadlifts with a limited range of motion until you have those down pat. 

Another thing to avoid is bending too much at the knees, Jess says, as this will change the muscles worked. Similarly, Archambault advises against locking out your knee; instead, keep the standing leg slightly bent.

Finally, avoid opening up your hips to the side, Jess says. This would mean you’re not properly working the hamstring of the standing leg—and that’s exactly where you want to feel the burn.

Takeaway

Single-leg deadlifts are a challenging yet effective way to build functional strength and work on unilateral training. However, they do require a good amount of flexibility and range of motion to do them effectively. To get there, you can work on your mobility and foundational moves first, such as traditional RDLs and deadlifts (and the other exercises mentioned above), before trying this more advanced move.

If you want some help getting there, try Mobility and Stretching classes on the Peloton App to help improve your range of motion, and try Lower Body Strength classes or a weight lifting program in Peloton Strength+ to help you build up the strength you need to master this challenging move.
