The Single Leg Romanian Deadlift (Single Leg RDL) is a powerful and versatile exercise that focuses on building strength, stability, and balance while working the muscles of the posterior chain, particularly the hamstrings, glutes, and lower back. While many exercises target these muscle groups in a more conventional way (such as the traditional Romanian Deadlift), the single-leg variation provides unique benefits that make it an excellent addition to any fitness routine. In this article, we’ll break down the mechanics of the exercise, its benefits, tips for proper execution, common mistakes to avoid, and some variations to challenge your body further.
What is a single leg rdl?
The Single Leg Romanian Deadlift is a unilateral (one-sided) variation of the Romanian Deadlift (RDL), which itself is a hinge movement that emphasizes the posterior chain—the group of muscles along the back of your body. These muscles include the hamstrings, glutes, lower back (erector spinae), and even the upper back and forearms. By performing the movement on a single leg, you significantly increase the demand on your balance, stability, and coordination.
Unlike the conventional deadlift, which requires both feet to remain on the floor, the Single Leg RDL requires you to balance on one leg while hinging at the hips. The opposite leg is lifted and extended behind you, creating a straight line from the head to the heel. This movement forces your body to engage the core, improve flexibility, and develop proprioception (the awareness of your body’s position in space).
How to Perform a Single Leg Romanian Deadlift
To perform a Single Leg Romanian Deadlift, follow these step-by-step instructions:
1. Starting Position:
- Begin by standing tall with your feet about hip-width apart. Hold a weight (such as a dumbbell, kettlebell, or barbell) in one hand (typically the hand opposite the working leg) or you can perform the exercise with bodyweight if you’re just starting.
- Engage your core by pulling your belly button in towards your spine, maintaining a neutral spine.
- Slightly bend the knee of the leg you’ll be standing on. This knee should remain soft throughout the movement and should not lock out.
- Set your shoulders back and down, ensuring good posture. Keep your gaze forward to help with balance.
2. Initiating the Movement: single leg rdl
- Begin the movement by hinging at the hips. Push your hips back while keeping your back straight and your chest lifted. Do not bend at the waist.
- As you lower your torso toward the floor, the non-supporting leg (the leg that is not planted on the ground) will naturally rise behind you. This leg should extend straight out from your body to create a straight line from your head to your heel.
- Keep the weight (whether dumbbell, kettlebell, or bodyweight) close to your body as you lower it towards the floor. Ideally, you want the weight to hang just in front of your standing leg.
3. Bottom Position:
- Lower the torso until it is nearly parallel to the floor or as low as you can control without compromising your form. The goal is to feel a stretch in the hamstrings of your standing leg.
- Keep your hips squared to the floor. Do not let them rotate open or closed. This is a common mistake, and preventing this rotation will engage your glutes and improve hip stability.
- Keep the non-supporting leg extended and aligned with your torso. It should not drop toward the floor or bend at the knee. This helps with balance and adds a challenge for your hip flexors and glutes.
4. Returning to Standing:
- To return to the starting position, push through the heel of your standing leg, engaging your glutes and hamstrings.
- Drive your hips forward as you lift your torso back up to standing. Simultaneously, lower the non-supporting leg back to the ground.
- Keep the motion controlled. The rising movement should be smooth and deliberate. The slower the movement, the more you’ll activate the target muscles and improve your balance.
5. Repeat:
- Perform all the repetitions on one leg, then switch to the other leg. If you are using a weight, you can alternate hands to balance the load.
Common Mistakes to Avoid
Even though the Single Leg RDL is a relatively straightforward exercise, several common mistakes can undermine its effectiveness or lead to injury. Here’s what to watch out for:
1. Rounding the Back:
- One of the most critical aspects of the Single Leg is maintaining a neutral spine. Allowing your back to round as you lower your torso places unnecessary strain on your lower back, which could result in injury over time. Keep your chest open, and your spine straight. Imagine that you’re pushing your hips back as if closing a car door with your hips.

2. Overreaching:
- Trying to reach too low in the movement without proper control can compromise form. If you cannot keep your balance or keep your hips square to the floor while going deep, don’t push it. Lower only as far as you can while maintaining control and alignment.
3. Allowing the Hips to Rotate:
- During the movement, your hips should remain level. If you notice your hips opening or twisting, you’re probably compensating for a lack of flexibility or balance. Focus on keeping your pelvis square to the floor and avoid overextending the non-supporting leg.
4. Locking the Standing Knee:
- The knee of your standing leg should remain slightly bent throughout the movement. Locking it out can place unnecessary strain on your joints and reduce your ability to balance. A slight bend allows the muscles to remain active and engaged.
5. Not Using Enough Hip Hinge:
- The Single Leg RDL is a hip-dominant exercise, meaning the movement should primarily come from your hips, not your knees. Make sure you push your hips back as you lower your torso rather than bending the knees excessively.
Benefits of the Single Leg Romanian Deadlift
The Single Leg Romanian Deadlift offers a wide range of benefits, both physically and functionally. Below are some of the key advantages of incorporating this exercise into your workout routine:
1. Targeting the Posterior Chain:
- The Single Leg primarily activates the muscles of the posterior chain, including the hamstrings, glutes, and lower back. These muscle groups are essential for posture, athletic performance, and everyday functional movements, making the Leg RDL an excellent choice for overall strength development.
2. Improved Balance and Stability:
- One of the primary benefits of performing Single Leg RDLs is the improvement in balance and stability. Since you’re working one leg at a time, your body has to engage the stabilizing muscles in the ankles, knees, and hips to maintain control. This enhances your ability to perform other athletic movements and reduces the risk of falls or injuries in daily life.
3. Core Engagement:
- The Single Leg forces your core to work hard to maintain stability during the movement. By engaging the abdominal muscles and the muscles of the lower back, you’ll build a stronger core, which can have a positive impact on overall functional strength and posture.
4. Better Hip Flexibility:
- The hip hinge movement involved in the Single Leg encourages improved flexibility in the hips and hamstrings. If you struggle with tight hamstrings, regularly practicing this exercise can increase your range of motion and overall flexibility.
5. Injury Prevention: single leg rdl
- By strengthening the posterior chain, the Single Leg can help prevent injuries, particularly in the lower back and hamstrings. Athletes and individuals with active lifestyles can benefit greatly from the Single Leg , as it helps to improve the resilience and strength of key muscle groups.
6. Unilateral Training:
- Training each leg individually allows you to address imbalances between the two sides of the body. Many people have one leg that is stronger or more stable than the other, and the Single Leg can help correct this asymmetry over time.
Variations of the Single Leg Romanian Deadlift
While the basic form of the Single Leg Romanian Deadlift is highly effective, there are several variations that can help you increase the challenge or target the muscles in slightly different ways:
1. Single Leg with Dumbbells or Kettlebells:
- Holding a dumbbell or kettlebell in one hand provides an additional resistance challenge. The added weight increases the demand on the glutes, hamstrings, and lower back, helping to build greater strength and muscle mass.
2. Single Leg with Barbell:
- For more experienced lifters, the barbell variation is an excellent way to load the exercise even more. Holding a barbell with both hands allows for greater overall weight and can lead to further muscle growth and strength development.
3. Bodyweight Single Leg RDL:
- For beginners, performing the exercise without added weight can help you focus on mastering the movement pattern before progressing to more challenging variations.
4 Leg RDL to Knee Drive:
- After coming back to the standing position, add a knee drive by pulling the non-supporting knee towards your chest. This variation not only works your posterior chain but also challenges the hip flexors and core.
5. Leg RDL with Resistance Bands:
- Adding resistance bands to the Leg RDL increases the challenge on the muscles during the eccentric (lowering) phase of the movement. This can help to increase time under tension, which is beneficial for muscle growth.
Conclusion
The Single Leg Romanian Deadlift is a highly effective and functional exercise that targets the posterior chain while improving balance, stability, and overall strength. By focusing on one leg at a time, it allows you to correct imbalances, strengthen key muscle groups, and improve your performance in other athletic activities. Whether you’re a beginner or an experienced lifter, the Single Leg RDL is a valuable addition to any fitness routine. Be mindful of proper form and technique, and be sure to incorporate variations to continue challenging your body and making progress.
