How to Do a Romanian Deadlift (RDL): Complete Form Guide

The Romanian deadlift is one of the best exercises for building strong hamstrings, glutes, and a resilient lower back. It's also one of the most butchered exercises in any gym.

Done right, the RDL teaches you to hip hinge properly—a fundamental movement pattern that protects your back and builds serious posterior chain strength. Done wrong, it's a lower back disaster waiting to happen.

Here's how to RDL correctly.

What Is a Romanian Deadlift?

The RDL is a hip hinge movement where you lower a weight by pushing your hips back while keeping your legs relatively straight. Unlike a conventional deadlift, the weight doesn't touch the floor between reps, and the movement emphasizes the eccentric (lowering) phase.

Primary muscles worked:

• Hamstrings (major emphasis)
• Glutes
• Erector spinae (lower back)
• Core (stabilization)
• Grip (holding the weight)

RDL vs Conventional Deadlift

| Romanian Deadlift | Conventional Deadlift | |---|---| | Starts from top | Starts from floor | | Slight knee bend throughout | Significant knee bend | | Hips push back | Hips and knees extend together | | Hamstring emphasis | Full posterior chain | | Weight stays in air | Each rep from floor | | Lower weight typically | Heavier loading possible |

Both are valuable. The RDL specifically targets hamstring development and teaches the hip hinge pattern.

The Setup

Starting Position

1. Start at the top: Unrack from a rack at hip height, or deadlift the weight up to standing
2. Grip: Slightly wider than hip width, overhand or mixed
3. Feet: Hip-width apart, toes forward or slightly out
4. Knees: Soft bend, maintained throughout
5. Chest: Up and proud
6. Shoulders: Pulled back, lats engaged
7. Core: Braced

Grip Options

Double overhand: Best for lighter weights and learning Mixed grip: One palm forward, one back—allows heavier loads Straps: Use when grip fails before hamstrings—no shame in straps for RDLs

The Movement

The Descent (Eccentric)

1. Initiate with hips: Push your butt straight back
2. Keep bar close: Weight slides down your thighs
3. Maintain flat back: No rounding at any point
4. Soft knee bend: Knees stay in same position—don't squat
5. Feel the stretch: Hamstrings should load and lengthen
6. Depth: Go until you feel a strong hamstring stretch (typically mid-shin to just below knee)

The Bottom Position

• You should feel significant hamstring tension
• Back is flat, not rounded
• Bar is close to shins
• Head neutral, looking at floor a few feet ahead
• Don't go so low that your back rounds

The Ascent (Concentric)

1. Drive hips forward: Squeeze glutes to stand
2. Keep bar close: Drag it back up your thighs
3. Stand tall: Full hip extension at top
4. Don't hyperextend: Neutral spine, not leaning back

The Lockout

• Standing tall
• Hips fully extended
• Glutes squeezed
• Shoulders back
• Don't lean back or thrust hips forward aggressively

Common RDL Mistakes

1. Rounding the Lower Back

The most dangerous error. Your lower back must stay flat throughout.

Fix:

• Reduce weight
• Focus on pushing hips back, not bending forward
• Think "proud chest" throughout
• Stop descent when back wants to round

2. Squatting the Weight

Bending your knees too much turns this into a squat-deadlift hybrid.

Fix:

• Keep a soft, fixed knee bend
• Push hips back, not down
• Feel the stretch in your hamstrings, not quads

3. Bar Drifting Away

If the bar gets away from your body, your lower back takes over.

Fix:

• Keep the bar touching your thighs throughout
• Think "drag the bar down your legs"
• Engage your lats to pull bar into body

4. Going Too Deep

More depth isn't better if it compromises form.

Fix:

• Stop when you feel a strong hamstring stretch
• Your flexibility determines your depth
• Most people stop between knee and mid-shin

5. Hyperextending at the Top

Aggressively thrusting hips forward at lockout stresses your lower back.

Fix:

• Stand tall with neutral spine
• Squeeze glutes, don't thrust
• Lockout is straight, not leaning back

6. Looking Up

Craning your neck up misaligns your spine.

Fix:

• Keep head neutral
• Look at floor 6-8 feet ahead at the bottom
• Chin stays tucked throughout

How Deep Should You Go?

Depth is individual and depends on hamstring flexibility:

Most people: Bar reaches somewhere between knee and mid-shin

Very flexible: May be able to go lower with good form

Less flexible: May only reach just below knee

The rule: Stop when you feel a strong hamstring stretch OR when your lower back starts to round—whichever comes first.

Never sacrifice form for depth. A shorter range of motion with perfect form beats a full range of motion with a rounded back.

Dumbbell Romanian Deadlift

A great variation, especially for beginners or training at home.

Execution

1. Hold dumbbells at your sides or in front of thighs
2. Same hip hinge pattern as barbell version
3. Dumbbells travel down front/side of legs
4. Keep weights close to body
5. Same depth guidelines apply

Advantages

• More freedom in hand position
• Can identify side-to-side imbalances
• Lower barrier to entry
• Good for home training

Single-Leg Romanian Deadlift

An advanced variation that builds balance, stability, and addresses imbalances.

Execution

1. Stand on one leg, other foot slightly off ground
2. Hold dumbbell or kettlebell in opposite hand
3. Hinge forward, reaching toward ground
4. Back leg extends behind for counterbalance
5. Keep hips square (don't rotate)
6. Return to standing by squeezing glute

Tips

• Start with bodyweight to learn balance
• Use wall or rack for support initially
• Don't sacrifice form for depth
• Keep standing knee soft but stable

Stiff-Leg Deadlift vs RDL

These terms are often used interchangeably, but there are subtle differences:

Romanian Deadlift:

• Slight knee bend maintained
• Doesn't touch floor between reps
• Hips push back

Stiff-Leg Deadlift:

• Legs more straight (but not locked)
• May touch floor between reps
• Bending forward emphasis

In practice, the execution is very similar. The key for both: hip hinge with a flat back.

Programming the RDL

For Strength

• 3-4 sets of 6-8 reps
• Heavier weight, controlled tempo
• 2-3 minute rest between sets

For Hypertrophy (Muscle Building)

• 3-4 sets of 8-12 reps
• Moderate weight, slower eccentric (3-4 seconds down)
• 60-90 second rest

For Beginners

• Start with dumbbells or light barbell
• 3 sets of 10-12 reps
• Focus entirely on form

Weekly Frequency

• 1-2 times per week
• Can pair with other hamstring work or keep as primary hamstring exercise
• Allow 48-72 hours recovery between sessions

RDL Warm-Up Routine

Before heavy RDLs, prepare your hamstrings and hips:

1. Leg swings: 10-15 each leg, front to back
2. Hip circles: 10 each direction
3. Bodyweight RDL: 10 reps, focus on the stretch
4. Light RDL: 1-2 sets with empty bar or light dumbbells

Accessory Exercises

Complement your RDLs with:

For hamstrings:

• Leg curls
• Nordic curls
• Good mornings

For glutes:

• Hip thrusts
• Glute bridges
• Cable pull-throughs

For lower back:

• Back extensions
• Reverse hypers
• Bird dogs

Common Questions

How much weight should I use? Start light and prioritize form. Most people use significantly less on RDLs than conventional deadlifts—60-70% is common.

Should my knees bend? Yes, slightly. Keep a soft bend (maybe 15-20 degrees) throughout. Don't actively bend more during the movement.

Can I do RDLs with back pain? It depends. For some people, properly performed RDLs help back pain by strengthening supporting muscles. For others, it aggravates issues. Consult a professional if you have back problems.

How is this different from a good morning? Good mornings have the weight on your back (barbell across shoulders). Same hip hinge pattern, different loading position.

Why can't I feel my hamstrings? Usually because you're squatting instead of hinging. Push your hips back further and keep knees from bending more.

The Bottom Line

The Romanian deadlift is essential for hamstring development and teaching proper hip hinge mechanics. The key is pushing your hips back while keeping a flat back—let your hamstrings stretch and load.

Start light. Master the movement pattern. Progress weight only when form is solid. Your hamstrings will grow, your back will get stronger, and you'll learn a movement pattern that protects you in everyday life.

Hinge with your hips. Keep the bar close. Feel the hamstrings. That's the RDL.
