The short answer
If you want more hamstring and glute muscle and you are still learning to hinge, start with the Romanian deadlift: it is lighter, simpler to set up and keeps the work where you want it. If you want whole-body strength, or your sport or job involves lifting from the ground, add the deadlift once your RDL is consistent. They are not rivals. Many programmes use the deadlift as the heavy lift and the RDL as a lighter, higher-rep accessory, and the hamstring exercises page shows where both sit in a week.
The mechanical difference comes down to the knee. In the deadlift the knees bend to reach a bar on the floor and then straighten as you stand, so the quads help and the hamstrings work through a shorter stretch. In the RDL the knees hold one slight bend while the hips travel back, so the hamstrings take more of the load as they lengthen, and the weight you can use drops.
Side by side
| What changes | Romanian deadlift | Deadlift |
|---|---|---|
| Where each rep starts | Standing, with the bar taken from a rack at thigh height | On the floor, from a dead stop |
| Knee bend | A small bend held throughout | Bent at the start, straight at the top |
| Main muscles | Hamstrings and glutes, with the lower back holding position | Glutes, hamstrings and back, with the quads helping off the floor |
| How low the bar goes | Until the hamstrings are stretched, usually knee to mid-shin | To the floor on every rep |
| Typical load | Clearly lighter | The heavier of the two |
| Learning curve | Easier; a good first hinge | Harder; the set-up and bar path take practice |
| Demand on the lower back | Steady, over a longer time under load | Highest as the bar breaks from the floor |
| Grip | Straps are common on higher-rep sets | Grip often limits heavy sets |
| Who it suits | Beginners, hamstring and glute goals, accessory work | Strength goals, lifters who already hinge well |
Neither lift's demands are a reason to avoid it; they are a reason to build the load gradually. If either one brings on back pain, stop and get it checked by a doctor or physiotherapist before you continue.
When the Romanian deadlift is the better fit
- You are learning to hinge. The RDL teaches the hips-back pattern without the extra step of starting from the floor.
- Your goal is hamstring and glute size. The long, controlled lowering under load is where the RDL earns its place.
- You already squat heavy. RDLs add work for the back of the legs with less overall fatigue than another heavy pull from the floor.
- You train with dumbbells. The dumbbell RDL works well, while a dumbbell deadlift from the floor gets awkward as the weights rise.
- You cannot yet reach a bar on the floor with a flat back. The RDL lets you train inside the range you control.
When the deadlift is the better fit
- Your goal is maximal strength, or you want to test your lifts or compete in powerlifting.
- Your sport or job involves picking heavy things up from the ground.
- You have learned the RDL and want a heavier hinge that also works your legs and grip hard.
- You want one lift that covers a lot of muscle when time is short.
Whichever you choose, the technique comes first. The deadlift page covers the set-up and bar path from the floor, and the Romanian deadlift page covers depth and knee position.
Using both in one programme
The simplest way to use both is to give each its own day, so the heavy pull and the hamstring work do not compete for the same energy.
| Day | Main hinge | Sets × reps | Then |
|---|---|---|---|
| Lower body A | Deadlift | 3–5 × 3–5, one or two reps left | Split squats and a core exercise |
| Lower body B | Romanian deadlift | 3 × 8–10, two reps left | Leg curls and a squat or leg press |
If you train legs only once a week, do the deadlift first and follow it with two or three lighter RDL sets, or alternate the two lifts week by week. The workout split calculator helps you place the days.
Keep the day after a heavy deadlift session clear of other heavy hinges, and if your lower back still feels tired when the RDL day arrives, drop a set rather than pushing through.
Mixing up the names
Three hinges are regularly confused. The stiff-leg deadlift keeps the knees straighter than an RDL and usually starts from the floor each rep. The Romanian deadlift starts at the top with soft knees and stops before the floor. The conventional deadlift pulls from the floor with the knees bending and then straightening. If a programme asks for a stiff-leg deadlift and you have only learned the RDL, use the RDL until a coach shows you the difference.
Is an RDL from the floor still an RDL?
Not really. Once every rep starts from the floor with a reset, it has become a deadlift or a stiff-leg deadlift. The RDL's defining features are starting from the top and keeping the bar under tension without touching down.
How the cues differ
For the RDL, think hips back and knees still, and let the bar slide down your legs. For the deadlift, think push the floor away, with the hips and shoulders rising together. Using the wrong cue is a common reason one lift turns into a poor copy of the other.
Both lifts at RPM
RPM's floor photos show squat racks with barbells and colour bumper plates, a rack of fixed barbells and a dumbbell rack, which covers both lifts. A lifting platform and the rules on dropping the bar are not confirmed, so ask about them on your free guided tour, and book personal training if you would like a coach to teach the hinge before you load it.
Questions, answered.
Is the RDL harder than the deadlift?
The RDL is easier to learn and uses less weight, but it can feel harder on the hamstrings because they stay under load for the whole set. The deadlift is the harder lift to perform well at heavy weights.
Which is better for the glutes, the RDL or the deadlift?
Both train the glutes hard through hip extension. The RDL keeps them under load for longer in a stretched position; the deadlift lets you use more weight. Either belongs in glute training, and the hamstring exercises page shows how to combine them.
Should I do RDLs and deadlifts in the same week?
Yes, if you recover well between sessions: keep one heavy and one lighter, on different days, as in the sample above. If your lower back feels tired going into the second session, drop a set or two.
How much lighter should my RDL be than my deadlift?
There is no fixed ratio worth chasing. Choose an RDL weight you can lower slowly with a flat back for the reps you plan; for most people that is clearly lighter than their deadlift.
Is a stiff-leg deadlift the same as an RDL?
No. The stiff-leg version keeps the knees straighter and usually starts from the floor; the RDL keeps a soft knee and starts from the top. They overlap, but they are different lifts.
