Single Leg Romanian Deadlift Strength Standards Calculator
Compare your Single-Leg Romanian Deadlift strength with Endura's strength standards for men and women at your bodyweight. A useful benchmark for a good one-rep max is our Intermediate standard: approximately 105 lb at 190 lb for a man and 61 lb at 150 lb for a woman.
How does your best lift compare? Enter your bodyweight, the exact exercise weight accepted by this calculator, and the reps you completed below. The calculator estimates your one-rep max and shows your strength level for your bodyweight. Use the exercise-specific approved repetition convention.
The calculator compares that estimated one-rep max with the Single-Leg Romanian Deadlift standards for your sex at your bodyweight. It preserves the calculator's existing equations, thresholds, and input meanings; the benchmark is a comparison target, not a working-set prescription.
Understanding Your Single-Leg Romanian Deadlift Strength Score
Your Single-Leg Romanian Deadlift strength score shows how strong you are for your bodyweight by placing your estimated 1RM into a tier like Novice (0.40–0.54×), Intermediate (0.55–0.74×), or Advanced (0.75–0.94×).
The calculator uses a hard set — like 70 lb for 6 reps — to estimate your one-rep max, then compares it to your bodyweight to determine your level.
For example, if you weigh 180 lb and hit 70 lb × 6 reps, your estimated 1RM is about 84 lb, which is 0.47× your bodyweight — placing you in the Novice tier. Another lifter who weighs 140 lb and hits the same set would be at 0.60× bodyweight, moving them into Intermediate even though both used the same weight.
How you perform each rep matters just as much as the weight you use. If one lifter hinges fully, keeps their balance, and stands tall at the top, while another cuts the range short or has to reset their foot mid-rep, the second lifter might use the same weight but isn’t meeting the standard used to score this lift.
This is a control test, not just a strength test — if you can’t stay balanced and hold position, you won’t be able to use the weight your hamstrings could otherwise handle.

Single-Leg Romanian Deadlift Strength Standards
Single-Leg Romanian Deadlift strength standards show how much weight you should be able to lift for your bodyweight, with Intermediate starting at 0.55× and Elite at 0.95× for men (0.40× and 0.70× for women).
These standards use your estimated 1RM divided by your bodyweight, so you can compare your strength accurately whether you weigh 120 lb or 220 lb.
For example, a 180 lb lifter with a 100 lb estimated 1RM is at 0.56× bodyweight, placing them in Intermediate. A 140 lb lifter using the same weight is at 0.71× bodyweight, which moves them into Advanced even though both hit the same set.

To read the table, find your bodyweight on the left and follow across to see the weight range for each strength level. If your estimated 1RM lands on the first number of a range, you are already in that higher tier — for example, 0.55× bodyweight is Intermediate, not Novice.
These standards assume strict reps. If you shorten the range, bend your knee too much, or lose balance and reset between reps, you may appear to reach a higher tier without meeting the standard used here.
Single-leg lifts scale differently than two-leg lifts. You can Romanian deadlift much more weight with both legs, but on one leg your balance and position limit how much weight you can actually use, which is why these standards are lower than traditional RDL numbers.
Use your most recent strict set in the calculator above to see exactly where you fall in these standards and what it will take to move up a tier.

How the Single-Leg Romanian Deadlift Calculator Works
The Single-Leg Romanian Deadlift calculator estimates your 1RM from a working set and compares it to your bodyweight to determine your strength tier.
It uses the Epley formula to turn your set into a max estimate — for example, 90 lb × 5 reps becomes about 105 lb — then divides that by your bodyweight to calculate your ratio and place you into a tier.
If you weigh 180 lb and your estimated 1RM is 105 lb, your ratio is 0.58× bodyweight, which falls into Intermediate. A heavier lifter using the same weight would land in a lower tier because the ratio is smaller.
This only works if your reps are strict. If you rush the reps, shorten the range, or use a slight hop to regain balance, the calculator will still produce a number, but it will overestimate your actual strength.
Changing equipment or setup can change your result. A controlled dumbbell set one week compared to a less stable barbell set the next can make your numbers look better or worse without any real change in strength.
This calculator rewards control — if you can’t stay balanced and hold position through the full hinge, your estimated 1RM will stall even if your legs could handle more weight.
Try a recent strict set in the calculator above and see how your estimated max and strength tier change as your form and control improve.
Single Leg Romanian Deadlift Testing Rules
Use these rules to keep load entry and counted repetitions consistent with this calculator. Attempts that change the listed load convention, movement, range, assistance, or finish should not be compared with these standards.
Where These Strength Standards Come From
| Factor | Impact on Standards |
|---|---|
| Balance requirement | Limits how much weight can be used on one leg |
| Range of motion | Full hinge reduces usable weight compared to partial reps |
| Stability demands | Requires more control than two-leg lifts |
| Execution standard | Strict reps ensure consistent comparisons |
Elite Single-Leg Romanian Deadlift Strength Levels
Elite Single-Leg Romanian Deadlift strength starts at 0.95× your bodyweight for men and 0.70× for women, which means you can control near bodyweight loads on one leg with clean reps.
At this level, you’re controlling heavy weight through a full hinge while staying balanced from start to finish, with no foot resets or loss of position.
For example, if you weigh 180 lb, an elite level is around a 170 lb estimated 1RM. That comes from sets like 150 lb for 3–4 clean reps with full control. If you weigh 140 lb, elite strength is closer to 130 lb, which demands the same level of control at a lighter bodyweight.
Strict execution separates real elite strength from inflated numbers. A lifter who controls 150 lb with a full hinge and steady balance is stronger than someone wobbling through 170 lb with short reps or a reset between each rep.
Most heavy single-leg hinges you see online don’t meet this standard — they shorten the range or rely on balance adjustments, which makes the weight look higher than it actually is.
Elite strength in this lift means the weight goes up without any change in how the reps look. If your depth, balance, or control drops as the weight increases, you’re not at an elite level yet.
Enter a recent strict set into the calculator above to see how close you are to reaching elite-level strength.
Single-Leg Romanian Deadlift Strength Compared to Other Lifts
The Single-Leg Romanian Deadlift uses much less weight than two-leg lifts, typically around 0.40×–0.75× bodyweight compared to 1.5×–2.0× for a standard Romanian deadlift.
This difference comes from having to stay balanced on one leg while controlling the hinge. Even strong lifters are limited by how well they can hold position, not just how much weight their hamstrings can handle.
For example, a 180 lb lifter who Romanian deadlifts 300 lb for reps will usually handle 90–120 lb per leg on the single-leg version with strict form. The drop in weight shows how much control and balance the lift demands.
| Lift | Typical Strength Level (Ratio) |
|---|---|
| Romanian Deadlift (2-leg) | 1.5×–2.0× bodyweight |
| Back Squat | 1.25×–1.75× bodyweight |
| Single-Leg Romanian Deadlift | 0.40×–0.75× bodyweight |
Form changes these comparisons quickly. If you shorten the range or rush your reps on the single-leg version, you can match heavier numbers, but those reps don’t reflect the same strength as a controlled hinge.
If your two-leg hinge is strong but your single-leg numbers stay low, the issue isn’t strength — it’s that you can’t stay balanced and hold position long enough to use more weight.
Use the calculator above to compare your Single-Leg Romanian Deadlift strength to your bodyweight and see how it stacks up against your other lifts.
Milestones in Single-Leg Romanian Deadlift Strength
Single-Leg Romanian Deadlift milestones give you exact bodyweight-based targets to hit next, with 0.55× marking your first real strength level and 0.95× defining elite for men (0.40× and 0.70× for women).
Each milestone represents more weight handled with the same balance, depth, and control on one leg.
For example, if you weigh 180 lb, your key milestones are around 100 lb (Intermediate), 135 lb (Advanced), and 170 lb (Elite). Moving from 90 lb to 100 lb with clean reps is real progress, while jumping to 110 lb with short reps or foot resets is not.
| Tier | Men (Ratio) | Women (Ratio) |
|---|---|---|
| Beginner | <0.40× | <0.30× |
| Novice | 0.40–0.54× | 0.30–0.39× |
| Intermediate | 0.55–0.74× | 0.40–0.54× |
| Advanced | 0.75–0.94× | 0.55–0.69× |
| Elite | ≥0.95× | ≥0.70× |
Hitting a milestone only counts if the reps meet the standard. If you shorten the range, bend your knee more than intended, or lose balance and reset between reps, the weight does not represent that level.
On this lift, the milestone is earned when you can hold position from start to finish under heavier weight. If your balance breaks before the rep finishes, you haven’t reached that level yet.
Use the calculator above to see which milestone you’ve reached and what weight you need to hit the next one.
