The Ultimate Guide to Mastering Barbell RDLs for Maximum Gains

Donʼt be the weirdo in the gym with huge quads and an embarrassing backside. You know the look: all business up front, party never in the back. If your hamstrings and glutes are lagging behind like they missed the gains train, itʼs time to learn how to do a barbell RDL (Romanian deadlift). If youʼve wondered how to bring up your posterior chain, start here. 

This compound lift doesnʼt just hit your hamstrings and glutes—it also puts the heat on your lower back, forearms, and grip. A stronger, more powerful posterior chain supports your squats and deadlifts, helps your pants fit better, and aids both athletic performance and everyday life. If you want the benefits of balance, strength, and resilience, the barbell RDL delivers. 

If you've got your pick of the litter—or you're wondering which barbell to add to your home gym — here's how to navigate your options depending on training goals, experience level, and how you want the movement to feel: 

Standard Barbell: This is the most common bar you'll find in commercial gyms and the goto for your typical lifter. Great for RDLs, as well as squats, deadlifts, bench press, rows, landmine moves, and more. Check out our all-purpose Colorado™ Bar. 

Deadlift Specialty Bar: If deadlifts are your focus, a specialty bar like the Hades™ Deadlift Bar is designed to flex slightly, allowing the lifter to pull from a slightly higher position— which can contribute to potentially lifting more weight. However, these bars are better suited for heavy deadlifts rather than RDLs. 

Technique Bar: These bars — like the Mesa™ Technique Bar — are lighter and shorter than a standard barbell, making them ideal for beginners who are learning new movement patterns. 

Cambered Swiss Bar: To the uninitiated, this bar may sound like a block of cheese, but it's actually a versatile multi-grip barbell that offers a unique grip and pulling angle. The cambered (curved) handles add a bit of instability, requiring more stabilizer engagement to maintain control throughout your lift. Check out our write-up on everything you can do on a cambered swiss bar. 

While the move looks simple enough, itʼs important to avoid the following form flubs to make sure youʼre targeting the right muscles and steering clear of injury. Clean barbell RDL form helps you get the benefits you want, safely. 

Distance From the Bar 

In an RDL workout, as you lower and lift, the bar should slide up and down your legs — like a close shave. If it swings out and away, it pulls your weight forward and can put unnecessary stress on your lower back. 

Rounded Back 

A neutral spine — aka a flat back — keeps your spine in its natural alignment and is the safest, strongest position for loading your hamstrings and glutes without stressing your lower back. Rounding your back to move the weight not only limits core and hamstring engagement, itʼs also a one-way ticket to lower-back pain. You can also toss on a lifting belt to help you keep your core braced and spine neutral. For more back-saving strategies, learn how to properly brace when lifting. 

Going Too Low 

Lower until you feel a stretch in your hamstrings — usually around mid-shin — then come back up to standing. Going lower just to go lower can force you past your flexibility limits and lead to back rounding, especially under load. 

Tempo RDLs: Take 3-5 seconds to lower during the eccentric phase, then power back to standing. Slowing it down increases your time-under-tension while also building strength, control, and some serious hamstring burn. 

Single-Leg RDL: Unilateral work, like the single-leg RDL, is a great way to identify and correct muscle imbalances. Stand on one leg with a slight bend in the knee. As you hinge at the hips, send your free leg back as your torso tips forward. Once you feel that stretch in your hamstring, drive through your grounded foot to return to standing. 

Berman recommends beginners start off doing bodyweight single-leg RDLs, then once the movement pattern is dialed in, progress to holding a dumbbell in the opposite hand. 

The Romanian deadlift and the deadlift may look similar, and both target the posterior chain — but the way they load and work the body is different. For a deep dive, see deadlift vs Romanian deadlift. 

The RDL primarily hits the hamstrings, while the conventional deadlift puts more emphasis on the glutes and back. Think of the deadlift as a combo of a hip hinge and a squat, while the RDL is a pure hip hinge — no squat involved. 

“The deadlift starts with a concentric movement with the pull from the ‘deadʼ position on the floor,” says Berman. “Repetitions with the RDL begin with an eccentric movement that stops about mid-shin.” 

Because of this, the conventional deadlift typically uses a larger range of motion, starting from the ground and finishing in a full lockout. The muscles worked overlap, but the emphasis shifts between lifts. 

One more key difference? Load. Most lifters can pull significantly more weight in a conventional deadlift than they can in an RDL. So be sure to adjust accordingly when switching between the two. 

Barbell RDL Benefits and Muscles Worked

Whatʼs the difference between a barbell RDL and a regular deadlift? 

Think of the RDL as the top half of a regular deadlift. The RDL starts from the top and focuses on the lowering (eccentric) phase of the movement, while a standard deadlift starts from the floor and works through a larger range of motion. Because of this, the RDL targets the hamstrings more, while the deadlift hits the glutes and back harder. For muscles worked and programming tips, see deadlift vs RDL above. 

Should the bar touch the floor during a barbell RDL? 

Once you start your RDL reps, the bar shouldnʼt touch the ground until your set is done. The barbell should lower to about your mid-shin before you send your hips forward and come back to standing. 

How to do RDLs with a barbell for beginners? 

Start off by mastering the form before you load up the bar with weight plates. Set your feet hip-width apart, and maintain a soft bend in your knees. Start with the barbell gripped in your hands in front of your thighs, then lower it to your mid-shin, keeping it close to your legs. Maintain a neutral spine—no rounding or arching—and drive your hips forward to come back to standing. If you want a quick primer on how to fix common issues, revisit the barbell RDL form tips above. 

Should my knees be locked or bent during a barbell RDL? 

You want a soft bend to your knees during this hip hinge exercise. Thisʼll keep tension in your hamstrings while allowing your hips to move freely. 

Why do I feel barbell RDLs in my lower back? 

While your lower back does work to stabilize your spine during the move, feeling pain, discomfort, or your back working over-time usually points to form issues. Be sure to brace your core, maintain a neutral spine, and make sure youʼre not going too low. A rounded back will take the work away from the hamstrings and place it on the back.
