Introduction to the Romanian Deadlift

RDL’s aye?

Created by an olympic weightlifting legend Nicu Vlad. Who is one of the only weightlifters to snatch over 200kg at a body weight under 100kg. 

Insane. 

So it goes without saying Nicu knew a thing or two about getting stronger leading him to the use of RDL’s.

While a great accessory for the deadlift, clean and jerk and snatch. 

The Romanian deadlift makes for an effective lower body exercise. Hitting the hamstrings, glutes ,erector spinae & adductors. 

(grip strength as well) 

The RDL Increases your Hamstring mobility and strength against hamstring injuries. Due to the load placed on the hamstrings being in a stretched position.

Which is a more effective way to increase mobility anyway

Using the RDL with your other hip hinge movements will only benefit you in the long run.  

What Makes the RDL Stand Out?

The Different strength curve

The RDL starts where the deadlift finishes.

Which leads to more time under tension in the hamstrings. 

Unlike hamstring curls where the hardest point is when your knee is flexed as much as possible. The hardest point for the RDL is when your knee is extended and your hamstrings are stretched. 

Hitting both strength curves is a good idea to increase strength across the range of motion. 

Hamstring injury prevention

A lot of people think that stretching is somehow going to prevent injuries.

Things like passive stretching may increase your muscles ability to be stretched but it won’t increase its ability to be strong at the end ranges of motion where most injuries happen. 

The key is to get both. Resistance training has been shown to increase mobility just as much as static stretching.

The RDL does this for the hamstrings. How? By adding sarcomeres (Muscle units) in a series rather than in parallel. 

What does this mean? 

When Hypertrophy (AKA muscle growth occurs) the body builds new muscle units called sarcomeres. It will either depending on the stimulus add them in parallel this leads to more size & strength in the muscle, or it can add it in series, leading to the ability to be strong in lengthened positions and also increases velocity of muscle contraction.

When the muscle adds in series you will both have the benefit of being strong at end ranges and have increased mobility while reducing the chance of a muscle strain. 

Less Fatigue than deadlifts 

Less weight can be moved in RDL’s than the deadlift making it less fatiguing. This is good if you want to progress without burning out, allowing your body to recover from deadlifts by interchanging with RDLS.  

What Muscles Are Involved In A Romanian Deadlift?

Primary Muscles 

Extension at the hip contracts the biceps femoris, semitendinosus and semimembranosus (AKA Hamstrings) Especially when the knee’s are relatively straight but with a slight knee bend like in a RDL. Unlike in the deadlift when the knee’s are more in flexion leading to larger recruitment of the quads, glutes and lower back.    

Thigh extension leads to the Gluteus max being used predominantly over the gluteus minimus and medialis. 

Secondary Muscles

Spinal erectors more specifically the thoracolumbar fascia helps the body transfer force between the lower and upper body by maintaining rigidity in the spine. 

Adductor magnus assists in thigh extension and stabilizes the pelvis during an RDL. 

Assisting Muscles

  • Rhomboids
    • Retraction of scapula during the RDL’s keeps your upper back from rounding
  • Trapezius 
    • Same function as the rhomboids 
  • Latissimus dorsi 
    • When you pull the bar close to your legs during an RDL this is called adduction. The Lats are the primary muscle involved when doing this. 

Complementing Other Strength Training Exercises

Synergy with Conventional Deadlifts

One of the standout features of the Romanian deadlift is how it complements other fundamental strength training exercises. The RDL, with its emphasis on the posterior chain, can enhance performance in conventional deadlifts. 

Enhanced Deadlift Performance

Since the RDL is quite like a deadlift the carry over can be great. By Working in a range of motion that most people are weaker in during a normal deadlift. 

This leads to increased strength in those weaker ranges and thus increases your deadlift ability.

Boosting Olympic Weightlifting

Romanian deadlifts are also highly beneficial for those involved in Olympic weightlifting. The movement's focus on controlled hip hinge and back strength directly supports the snatch and clean and jerk techniques. By improving the lifter's ability to handle the barbell in the hip area, RDLs make an impact on the overall technique and success in these complex lifts..

Mastering the Romanian Deadlift: Execution and Integration

Proper Technique for Maximum Benefits

Achieving the full benefits of the Romanian deadlift depends on proper form and technique. Incorrect execution can not only reduce the effectiveness of the exercise but also increase the risk of injury. Here's how to perform an RDL correctly:

Starting Position

  • Stand with your feet hip-width apart, knees slightly bent.
  • Hold a barbell or dumbbells in front of your thighs with an overhand grip.
  • Keep your back straight, shoulders back, and chest up.

The Descent

  • Hinge at the hips, pushing them back as you lower the barbell toward the ground.
  • Maintain a slight bend in the knees throughout the movement.
  • Keep the barbell close to your legs to maximize the use of your hamstrings and glutes.
  • Lower the weight until you feel a stretch in your hamstrings or until your upper body is parallel to the floor.

The Ascent

  • Drive through your heels to return to the starting position, focusing on using your glutes and hamstrings to lift the weight.
  • Keep the core engaged and back straight as you rise.
  • The movement should be fluid and controlled, with the power coming from the hips.

Integrating RDLs into Your Workout Routine

Incorporating the Romanian deadlift into your workout regimen can be done in various ways, depending on your fitness goals:

For Strength

  • Include RDLs in your lower-body strength days, pairing them with squats, leg presses, and calf raises.
  • Perform 3-6 sets of 3-5 repetitions with a weight that allows you to have about 1-2 Reps in reserve, with 3-4 mins rest between sets. 
  • Add weight each week at 5kg increments, then 2.5kg.
  • Once you can’t add weight anymore. Add weight to only the first set and reduce the weight for the back off sets. 

For Muscle Growth

  • Use RDLs as part of a hypertrophy-focused leg day.
  • Aim for 3-5 sets of 8-12 repetitions with moderate weight that allows you to have 2-4 Reps in reserve.
  • To progress add reps from 8 to 12 when you hit 12 reps for 3 sets increase weight by 5-2.5kg then drop the reps to 8 reps then repeat. 

Common Mistakes to Avoid

  • Bend the knees to much: Removes the focus of the exercise away from the hamstrings
  • Lifting Too Heavy, Too Soon: Make sure you start light and add weight progressively. Not too fast. 
  • Rounding Upper back: Where you look is where your body will go. Look up to avoid rounding your upper back excessively.
  • Hips go back not down:  Remember to push your hips back like closing a door with your butt. This will make sure you maximize the hamstring tension. 

Advanced Variation

Once you are comfortable with the standard Romanian deadlift, consider trying some variations to challenge your muscles differently:

Single-Leg RDL

  • This variation increases the challenge to your balance and core, intensifying the focus on the working leg.
  • Good if you feel one leg is weaker than the other. 

The Romanian deadlift is a versatile exercise that strengthens the posterior chain, enhances athletic performance, and improves daily functional strength. Mastering the correct form and effectively integrating RDLs into your workout routine can lead to significant improvements in strength, stability, and overall health. Whether you are an athlete or a fitness enthusiast, the Romanian deadlift is a worthwhile addition to any fitness program.
