What Can I Do Instead of Rdls With Dumbbells

You’re trying to do dumbbell RDLs to build your hamstrings and glutes, but all you feel is a nagging strain in your lower back. You’ve watched videos, you’ve tried to keep your back straight, but something isn’t clicking. It’s one of the most common frustrations in the gym, and it keeps people from building the strong posterior chain they want.

Key Takeaways

• If you're wondering what can I do instead of RDLs with dumbbells, Good Mornings are the most direct replacement that removes grip as a limiting factor.
• Lower back pain during RDLs is a sign you are lifting with your spine instead of hinging at your hips.
• Cable Pull-Throughs are the best exercise for beginners to safely learn the hip hinge motion and feel it in their glutes and hamstrings.
• If your grip fails before your legs, switch to Single-Leg RDLs to use less weight for the same challenge.
• You can't substitute RDLs with Leg Curls alone; RDLs train hip extension, while leg curls train knee flexion, and you need both.
• The goal of any RDL alternative is to achieve hip extension-pushing the hips back and then driving them forward-to target the glutes and hamstrings.

Why Dumbbell RDLs Are So Hard to Get Right

If you're searching for what can I do instead of RDLs with dumbbells, you're not alone. You’ve probably felt that familiar, frustrating ache in your lower back the day after trying them, with barely any soreness in your hamstrings. This happens to at least 8 out of 10 people when they first start.

The reason is simple: the Romanian Deadlift is a hip hinge, not a squat. But most of us spend our lives squatting-sitting down, standing up. Our brains are wired to bend our knees to lower ourselves. An RDL asks you to do the opposite: keep your knees relatively straight and push your hips backward. This feels unnatural, and your body defaults to what it knows: bending your spine.

Here are the three main reasons dumbbell RDLs go wrong:

1. You're Lifting With Your Back: Instead of initiating the movement by pushing your hips back, you bend at the waist. Your spine rounds, and your lower back erectors take on the entire load. They aren't designed for that, and they’ll let you know they're unhappy.
2. The Dumbbells Drift Forward: To keep your balance while your back rounds, the dumbbells drift away from your shins. This acts like a lever, dramatically increasing the strain on your lower back. The dumbbells should stay so close they almost scrape your legs the entire time.
3. Your Grip Gives Out: As you get stronger, you'll find your hands can't hold the 50, 60, or 70-pound dumbbells your hamstrings can actually handle. Your grip becomes the weak link, and your hamstrings never get the stimulus they need to grow.

Feeling this doesn't mean you're weak or doing it wrong on purpose. It just means the dumbbell RDL isn't the right exercise for you *right now*. You need an alternative that either forces good form or removes the weak links.

The 5 Best Alternatives to Dumbbell RDLs

Forget the frustrating dumbbell RDL for now. These five alternatives will target the exact same muscles-your hamstrings and glutes-but in a way that’s safer, more effective, and easier to learn. Pick one based on the equipment you have and your specific issue.

1. Good Mornings (Barbell)

This is the most direct substitute for an RDL. By placing a barbell on your back, you completely remove grip strength as a limiting factor. Furthermore, the bar's position forces you to maintain a neutral spine. If you round your back, you'll feel it immediately and be forced to correct your form.

How to do it: Place a light barbell on your traps, just like a high-bar squat. Keep your feet shoulder-width apart and soften your knees. Push your hips straight back as if trying to touch a wall behind you. Go down until you feel a deep stretch in your hamstrings, then squeeze your glutes to return to the starting position. Start with just the 45-pound bar.

Who it's for: Anyone whose grip fails on dumbbell RDLs or who wants to load the hinge pattern with heavier weight.

2. Cable Pull-Throughs (Cable Machine)

This is the single best exercise to learn how a proper hip hinge should feel. The cable actively pulls your hips backward, teaching you the main mechanic of the RDL without any load on your spine. It's almost impossible to do this movement with your lower back.

How to do it: Set a cable pulley to the lowest setting with a rope attachment. Stand facing away from the machine, holding the rope between your legs. Take a few steps forward to create tension. Let the weight pull your hips back, feeling a stretch in your hamstrings. Then, drive your hips forward and squeeze your glutes hard at the top.

Who it's for: Beginners who can't feel their glutes/hamstrings working or anyone recovering from lower back pain.

3. Kettlebell Swings (Kettlebell)

While RDLs are slow and controlled, kettlebell swings are explosive. However, they are built on the exact same hip hinge foundation. Mastering the swing will build a powerful and athletic posterior chain. The focus is on a rapid, forceful hip extension.

How to do it: Stand with your feet slightly wider than your shoulders. Hike the kettlebell back between your legs, then explosively drive your hips forward, snapping them to attention. The power comes from your hips, not your arms-your arms are just guiding the bell. A 35-pound (16kg) kettlebell is a great starting point for men, and an 18-pound (8kg) one for women.

Who it's for: People who want to build explosive power and conditioning while still training the hip hinge.

4. Glute-Ham Raises (GHR) or Nordic Curls

The GHR takes your lower back and hips completely out of the equation. This movement isolates the hamstring's other primary function: knee flexion. It's brutally effective and will build incredible hamstring strength and size with zero spinal load.

How to do it: On a GHR machine, lock your ankles in and place your knees on the pad. Start with your torso upright. Lower your body toward the floor slowly, using only your hamstrings to control the descent. Use your hands to push yourself back up. If you don't have a GHR, you can do Nordic Curls by having a partner hold your ankles down.

Who it's for: Anyone with persistent back issues or who wants to purely isolate their hamstrings.

5. Single-Leg RDLs

This might seem counterintuitive, but switching to one leg can solve many RDL problems. First, it requires less weight, which helps if your dumbbells are too light or your grip is a problem. A 40-pound dumbbell for a single-leg RDL feels as challenging as using two 70-pound dumbbells for a regular RDL. It also forces you to engage your core and stabilizer muscles.

How to do it: Hold a dumbbell in your right hand. Stand on your left leg, keeping it slightly bent. Hinge at the hip, letting your right leg extend straight behind you for balance. Lower the dumbbell toward the floor until you feel a deep stretch in your left hamstring. Return to the start.

Who it's for: People with limited dumbbell weights or those whose grip fails on heavier bilateral RDLs.

How to Fix Your Hip Hinge (The Root Cause)

Switching exercises will help, but the real long-term solution is to master the hip hinge. If you can fix this fundamental movement pattern, you'll unlock dozens of exercises and bulletproof your lower back. The problem isn't the RDL; it's the execution.

Here is a simple drill you can do right now, without any weights.

The Wall Tap Drill

This is the easiest way to feel the difference between a hinge and a squat.

1. Stand about 6 inches in front of a wall, facing away from it.
2. Place your feet shoulder-width apart.
3. Without bending your knees more than a few inches, push your butt straight back until it taps the wall.
4. Squeeze your glutes to come back to a standing position.

That feeling of reaching your hips *backward* is the hinge. If you bent your knees and dropped your hips *downward*, you did a squat. Practice this 10-15 times. Then, take a small step forward and try again. The goal is to see how far you can get from the wall while still being able to tap it with your hips.

The 3-Step Hinge Checklist

When you perform any hinge movement (Good Mornings, Pull-Throughs, RDLs), run through this mental checklist on every single rep:

1. Soften Knees: Your knees should be unlocked and slightly bent, but they should not bend any further during the movement.
2. Hips Go Back: Initiate the movement by pushing your hips backward, not by bending over. Imagine a rope is tied around your waist and is pulling you backward.
3. Spine Stays Neutral: Keep your chest up and your back flat. A good cue is to imagine you have a glass of water on your lower back that you can't spill. Only go as low as you can while maintaining this flat back.

Mastering these three steps will fix 99% of the issues that cause back pain during RDLs.

Programming Your RDL Alternative: Sets, Reps, and Frequency

Knowing the exercises is one thing; knowing how to put them into your routine is another. You can't just randomly throw them in. Here’s how to program them effectively based on your goals.

Your hamstrings are a large muscle group that responds well to both heavy weight and high volume. You should train them 1-2 times per week.

For Building Maximum Strength

If your goal is pure strength, you need to lift heavy for lower reps. Good Mornings are perfect for this.

• Exercise: Barbell Good Morning
• Sets: 3-4
• Reps: 6-8 per set
• Rest: 2-3 minutes between sets to ensure full recovery.

In this rep range, you should be using a weight that is challenging to complete the 8th rep with perfect form.

For Building Muscle Size (Hypertrophy)

For muscle growth, you want to increase the total volume and time under tension. This means more reps with slightly lighter weight.

• Exercises: Cable Pull-Throughs, Single-Leg RDLs, Glute-Ham Raises
• Sets: 3-4
• Reps: 10-15 per set
• Rest: 60-90 seconds between sets.

The goal here is to feel a deep stretch and a strong contraction in the hamstrings and glutes on every rep.

For Building Explosive Power

If you're an athlete or just want to be more explosive, kettlebell swings are your best bet. The programming is different, focusing on power output.

• Exercise: Kettlebell Swings
• Sets: 5-10
• Reps: 10-20 per set
• Rest: 30-60 seconds between sets.

Every rep should be as explosive as possible. This is often done as a finisher at the end of a workout.

Example Leg Day Split:

• Day 1 (Quad-Focused): Barbell Squats, Leg Press, Leg Extensions, Calf Raises.
• Day 2 (Hamstring-Focused): Good Mornings (6-8 reps), Single-Leg RDLs (10-12 reps), Seated Leg Curls (12-15 reps), Calf Raises.

This ensures you're hitting your legs from all angles without overtaxing them in a single session.

Frequently Asked Questions

Can I just do regular deadlifts instead of RDLs?

Yes, but they serve different purposes. A conventional deadlift is a full-body lift that starts from the floor and involves significant quad and back engagement. An RDL is an accessory lift that isolates the hamstrings and glutes by focusing only on the hip hinge portion of the movement.

Why do I feel RDLs in my lower back and not my hamstrings?

This happens because you are initiating the lift by bending your spine instead of pushing your hips back. Your body is using your lower back erectors to move the weight, not your hamstrings and glutes. To fix this, practice the Wall Tap Drill and start with Cable Pull-Throughs to learn the proper sensation.

Are leg curls a good substitute for RDLs?

Leg curls are a great hamstring exercise, but they are not a direct substitute for RDLs. Leg curls isolate the knee flexion function of the hamstring. RDLs and their alternatives train the hip extension function, which is crucial for building a powerful posterior chain and involves the glutes. You should include both types of movements in your program.

How far down should I go on an RDL or Good Morning?

You should only go as low as your hamstring flexibility allows while maintaining a perfectly flat back. For most people, this is when the weight is just below the kneecaps. Once you feel a deep stretch in your hamstrings, that's your end range of motion. Going lower usually forces your back to round, which defeats the purpose of the exercise.

Conclusion

The problem was never the dumbbell RDL itself, but the difficulty of mastering the hip hinge under load. By choosing a better alternative like a Good Morning or Cable Pull-Through, you can train the exact same muscles effectively and safely.

Focus on mastering the hinge movement first. Once you can do that, you'll find that your entire lower body training transforms, and you can build the strong hamstrings and glutes you've been working for.
