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.
What Is a “Good” Single-Leg Romanian Deadlift?
A good Single-Leg Romanian Deadlift is at least 0.55× your bodyweight for men (0.40× for women), which puts you into the Intermediate tier where you can control meaningful weight with clean reps.
At this level, you’re controlling the full hinge — reaching a clear hamstring stretch, staying balanced on one leg, and standing tall without resetting between reps.
For example, if you weigh 180 lb, a good standard is around 100 lb for a clean set, which gives you an estimated 1RM near 110 lb (0.61× bodyweight). If you weigh 140 lb, hitting the same 100 lb puts you closer to 0.71×, which is already Advanced — so “good” depends on your size, not just the weight.
In a typical gym, most people either stay too light or rush their reps to handle more weight. A lifter who controls 90 lb with a full stretch and steady balance is stronger by this standard than someone wobbling through 110 lb with short reps.
If you can repeat the same clean reps without losing balance or cutting depth, you’re getting stronger. If the weight goes up but you have to shorten the range or reset your foot, you haven’t moved up a tier.
Use the calculator above with a recent strict set to see if your current numbers meet the “good” standard for your bodyweight.
Average Single-Leg Romanian Deadlift Strength by Experience Level
Average Single-Leg Romanian Deadlift strength sits between 0.40× and 0.74× bodyweight, which places most lifters in the Novice to Intermediate tiers.
This range reflects what most lifters can control on one leg once they’ve learned the hinge pattern but are still limited by balance and position before pure strength.
For example, a 180 lb lifter working with 80–110 lb for solid sets will typically land in this range, with estimated strength between 0.44× and 0.61× bodyweight. A newer lifter may sit closer to 70 lb (0.39×), while someone with better control and strength will push past 100 lb.
| Experience Level | 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× |
Form has a direct impact on where you fall in this table. If your back leg drops early, your knee bends too much, or you lose balance and reset between reps, the weight you’re using doesn’t reflect your actual strength level.
Most lifters get stuck in this range because they can’t hold position long enough to use more weight. Until you can stay balanced through the full hinge, your strength won’t move up the table even if your legs could handle more.
Enter your latest set into the calculator above to see exactly where you fall in this table and what it will take to move to the next level.
Test Your Single-Leg Romanian Deadlift Strength
To test your Single-Leg Romanian Deadlift strength, enter your bodyweight, the weight you used, and how many clean reps you completed on one leg.
Use a hard set where the last 1–2 reps are challenging but still controlled — for example, 90 lb for 5 reps with a full hinge, steady balance, and no foot resets. That gives a reliable estimate of your max without needing to test a true single.
If you weigh 180 lb and perform 90 lb × 5 reps with strict form, your estimated 1RM is about 105 lb, which is 0.58× bodyweight — placing you in the Intermediate tier. If you use the same weight but lose balance or shorten the range, that number does not reflect your actual strength.
A clean test means every rep starts balanced, reaches a full hamstring stretch, and finishes with your hips fully extended. If your back leg drops early, your knee bends too much, or you have to reset between reps, the set doesn’t count toward your true level.
Use the same leg, same setup, and same standard each time you test. Changing any of these — switching legs, using straps one week and not the next, or adjusting your range — makes it hard to track real progress.
Enter a recent strict set into the calculator above and compare a few different sets to see which one gives the most accurate estimate of your current strength.
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.
Proper Single-Leg Romanian Deadlift Testing Standards
A proper Single-Leg Romanian Deadlift test means every rep is controlled, balanced, and reaches a full hamstring stretch before you stand back up.
Start each rep steady on one leg, hinge your hips back until your torso is close to parallel, and finish by standing tall without your foot touching down or shifting position. This is the standard used to calculate your strength level.
For example, if you perform 90 lb for 5 reps while staying balanced and hitting full depth each time, that set reflects your true ability. If you use the same weight but tap your foot down or shorten the range halfway through, the number you enter will overstate your strength.
Check your reps against this standard:
- Start balanced on one leg with no hopping or resetting
- Lower until you feel a clear hamstring stretch
- Keep a slight knee bend without turning it into a squat
- Stand up fully with hips locked out at the top
- Keep the same control and tempo on every rep
If your form changes mid-set — your back leg drops early, your balance shifts, or you rush the last reps — stop the set there. Counting those reps will give you a number that doesn’t match your actual strength.
Retest under the same conditions each time. Use the same leg, similar equipment, and the same depth so your results reflect real progress instead of changes in setup.
Use a recent set that meets these standards in the calculator above to get an accurate strength score.
How to Improve Your Single-Leg Romanian Deadlift
To improve your Single-Leg Romanian Deadlift, build your ability to stay balanced and control the full hinge before trying to add more weight.
Most lifters don’t get stuck because their hamstrings are too weak — they get stuck because they can’t hold position on one leg long enough to use heavier weight. Fixing that is what moves you up the strength tiers.
For example, a 180 lb lifter stuck at 90 lb for months often loses balance or cuts the range short on the last reps. Once they clean up their form and control the full hinge, that same lifter can usually move to 100–110 lb quickly, pushing their ratio from 0.50× into the 0.60× range.
Common mistakes that hold this lift back:
- Rushing the descent instead of controlling the hinge
- Letting the back leg drop instead of staying aligned
- Bending the knee too much and turning it into a squat
- Chasing heavier weight before reps are consistent
Progress this lift by earning each increase. Stay at the same weight until you can complete every rep with full depth and balance, then move up by small jumps — 5–10 lb is enough to drive progress.
The goal is to handle more weight without changing how the reps look. If your form breaks when the weight increases, you haven’t actually gotten stronger in this lift.
Enter your latest strict set into the calculator above to see if your progress is moving you toward the next strength tier.
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.
Where These Strength Standards Come From
These Single-Leg Romanian Deadlift standards are built from Romanian deadlift strength levels, adjusted to match what lifters can actually control on one leg.
A two-leg Romanian deadlift allows much higher weight because you’re stable on both feet. When you switch to one leg, balance and position limit how much weight you can use, so the ratios are scaled down to reflect real performance.
For example, a 180 lb lifter who Romanian deadlifts 300 lb (1.67× bodyweight) will usually handle around 100–130 lb per leg with strict form. That places them in the Intermediate to Advanced range using these standards.
| 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 |
Different sources show higher numbers when they allow shorter reps or balance assistance. Those numbers are not directly comparable to the strict standard used here.
These standards are trustworthy because they are based on full-range, controlled reps that can be repeated the same way each time. That makes your results consistent and your progress measurable.
Use the calculator above with the same strict standard to compare your strength and track how it improves over time.

Frequently Asked Questions
How strong should my Single-Leg Romanian Deadlift be?
Your Single-Leg Romanian Deadlift should be at least 0.55× your bodyweight for men (0.40× for women) to reach a solid Intermediate level. For example, a 180 lb lifter should aim for around a 100 lb estimated 1RM to meet this standard. If you reach that weight by shortening the range or resetting your foot mid-rep, it doesn’t count toward that level. Smaller lifters will hit higher ratios with less weight, which is why bodyweight matters when judging strength.
What is a good weight for a Single-Leg Romanian Deadlift?
A good working weight is one that puts you between 0.55× and 0.75× bodyweight with clean reps, not just heavier weight for the sake of it. For example, using 90–110 lb at 180 lb bodyweight places you in the Intermediate range if your reps are controlled. If you need to rush or shorten your reps to handle that weight, it’s too heavy for your current level. Your goal is to use a weight you can repeat with the same form every set.
Why is my Single-Leg Romanian Deadlift so much weaker than my regular RDL?
Your Single-Leg Romanian Deadlift is lower because balance limits how much weight you can use, not your hamstrings. For example, a lifter who Romanian deadlifts 300 lb (1.67× bodyweight) may only handle 90–120 lb per leg with strict form. If you try to match your two-leg numbers by shortening the range or rushing reps, the weight goes up but your strength does not. This lift exposes how well you can control the hinge on one leg.
Should I use dumbbells, kettlebells, or a barbell?
Dumbbells or kettlebells are the best choice for most lifters because they allow better balance and control on one leg. For example, holding a single 80 lb dumbbell lets you stay steady and hinge cleanly, while a barbell can make balance harder and change how the rep feels. If switching equipment causes you to lose balance or shorten the range, your results won’t match your actual strength. Use the setup you can control consistently.
How many reps should I use for the Single-Leg Romanian Deadlift?
Most lifters should use 5–8 reps per set to build strength while maintaining control. For example, a set of 90 lb for 5 reps gives a reliable estimate of your strength without your form breaking down. If you go too high in reps, balance usually fails before strength, which lowers the quality of the set. Each rep should look the same from start to finish.
Why do I keep losing balance during Single-Leg Romanian Deadlifts?
You lose balance because you’re not staying in position through the hinge, not because the weight is too heavy. For example, if your back leg drops early or your hips rotate, you’ll struggle to control even moderate weight like 70–90 lb. If you shorten the range or tap your foot down to stay upright, the rep no longer meets the standard. Staying balanced comes from controlling your position, not just reducing weight.
Does the Single-Leg Romanian Deadlift build muscle or just balance?
The Single-Leg Romanian Deadlift builds both muscle and balance by loading your hamstrings and glutes while forcing you to control the movement on one leg. For example, lifting 100 lb for clean reps challenges your posterior chain and your ability to stay stable at the same time. If your reps turn into quick, shallow movements, you lose both the muscle-building and strength benefit. The goal is controlled tension through the full hinge.
How do I know if my reps count as strict?
Your reps count as strict if you stay balanced, reach a full hamstring stretch, and stand up fully without resetting your foot. For example, 90 lb for 5 reps only counts if every rep follows that standard. If you shorten the range, bend your knee too much, or touch your foot down between reps, those reps don’t reflect your actual strength. Strict reps are what make your results consistent and comparable over time.
