Deadlifts vs RDLs: What's the Difference, and Why It Matters

strength | November 05, 2026

They look almost identical from across the gym, but they're built for different jobs. Here's how to tell them apart and get the most out of both.

Same Bar, Different Lift

Look around the weights floor and you'll probably spot both. One person pulls a loaded bar up off the floor. Another stands tall holding a bar, then lowers it down their legs and stops just past the knee without ever letting it touch the ground. Both often get called "deadlifts", and it's one of the most common mix-ups I see as a coach.

It matters, because they don't train your body in the same way. Both are hip hinges: you bend at the hips rather than the knees, keep your back flat, and use your glutes and hamstrings to stand back up. But where the rep starts, what your knees do and how low you go are all different, and those differences decide which muscles do most of the work.

The Deadlift: Strength From the Floor

A deadlift starts on the floor, from a dead stop, every single rep. That's where the name comes from. There's no bounce and no momentum to help you, just you and a bar that isn't moving yet.

To set up, stand with your feet about hip width apart and the bar over the middle of your feet. Hinge down and bend your knees until your hands reach the bar, with your shins close to it and your hips a little higher than your knees. Your arms should be on the outside of your knees. Brace your core and your lats, then push the floor away with your legs and drive your hips forward until you're standing tall.

Because your knees bend more at the start, your quads help break the bar off the floor, while your glutes, hamstrings and back take over to finish the lift. Add your grip and core, and it's one of the most complete full-body lifts there is. It's also the hinge where you can lift the most weight, which makes it brilliant for building overall strength. And it's the same movement you use every time you pick something heavy up off the ground.

The RDL: It's All About the Lower

An RDL (Romanian deadlift) starts at the top. You pick the bar up from a rack, or deadlift it up once, and begin each rep standing tall.

Soften your knees slightly and keep them in that position for the whole set. Then push your hips back, as if you're trying to close a car door behind you with your bum, and let the bar slide down the front of your thighs. Stop when you feel a strong stretch through your hamstrings and your back is still flat. For most people that's somewhere between just below the knee and mid-shin. Then drive your hips forward to stand back up.

The bar never touches the floor, so your glutes and hamstrings stay under tension for the whole set. The lowering phase is where the work happens, so take your time on the way down, around two to three seconds. You'll use less weight than you would for a deadlift, and that's the point. The RDL trains the back of your legs in a stretched position, which is where a lot of us are weakest and where much of the glute and hamstring shape comes from.

The Key Differences at a Glance

Where it starts. A deadlift starts on the floor. An RDL starts standing at the top.

What your knees do. In a deadlift your knees bend and straighten as part of the lift. In an RDL they stay softly bent and fixed in place, while your hips do the moving.

How low you go. A deadlift always goes from the floor to standing. An RDL only goes as low as your hamstrings allow with a flat back, so your body sets the depth, not the floor.

What it trains most. The deadlift is a full-body strength lift. The RDL focuses on your glutes and hamstrings.

How heavy. Deadlifts are where you go heavy. RDLs use a moderate weight you can control slowly through every rep.

Common Mistakes (and How to Fix Them)

Squatting your RDL. As the bar goes down, the knees bend more and more until it turns into a half squat, and your quads take the work away from your hamstrings. Fix it by thinking "hips back", not "bar down", and keep your shins roughly vertical.

Chasing depth. Rounding your back to get the bar lower doesn't make the RDL better. It just moves the load off your hamstrings and onto your lower back. Stop where your hamstrings stop you. That range will grow with time.

Letting the bar drift. The further the bar moves away from your legs, the more your lower back has to hold it. On both lifts, keep the bar close enough to brush your legs on the way up and down.

Yanking the deadlift off the floor. Jerking the bar up before you're braced is how the lift gets sloppy. Pull the slack out of the bar first, so it's tight against the plates, brace your core, then push the floor away.

Leaning back at the top. You don't need to throw your shoulders back past vertical to finish either lift. Stand tall, squeeze your glutes and keep your ribs down. That's "lockout".

So, Which One Should You Do?

Ideally, both. They work well together, as long as each one has its own job.

Use the deadlift as a main strength lift. Put it at the start of your session while you're fresh, and keep the reps lower with a heavier weight. Use the RDL as a secondary lift later in the session, with a moderate weight, more reps (around 8 to 12) and a slow, controlled lowering.

If you're new to lifting, the RDL is a great place to start. Learning it first with dumbbells or a light bar teaches you how to hinge at your hips and feel your glutes and hamstrings working. Once that pattern feels natural, the deadlift from the floor tends to come together much more easily.

Learn the Hinge, and the Rest Follows

When I swapped years of cardio for a barbell, learning to hinge properly was one of the skills that changed how I trained. It's not the flashiest movement in the gym, but it builds strong glutes, strong hamstrings and a back that can handle everyday life, from carrying shopping to picking up a toddler.

So next time you walk up to the bar, ask yourself one question: am I starting from the floor, or from the top? Get that right, and you'll be training the right muscles for the job, every single rep.
