Stiff Leg Deadlift Strength Standards Calculator
Compare your Barbell Stiff-Leg 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 158 lb at 190 lb for a man and 91 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 Barbell Stiff-Leg 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 Stiff-Leg Deadlift Strength Score
Your stiff-leg deadlift strength score shows how your hinge strength ranks by comparing your estimated 1RM to your bodyweight, with Intermediate starting around 0.83× and Elite at 1.47× or higher.
The calculator takes the weight you lifted and reps completed, estimates your one-rep max using the Epley formula, then compares that number to your bodyweight to assign a strength tier. For example, if you lift 225 lb for 8 reps at 180 lb bodyweight, your estimated 1RM is about 285 lb, which equals roughly 1.58× your bodyweight — placing you in the Elite tier for men.
This score reflects how much load you can control while your hamstrings are fully stretched with only a slight knee bend. The bar stays in contact with your legs as your hips move back, and the rep ends when hamstring tension stops the descent without your spine rounding.
The same performance can represent very different strength levels depending on bodyweight. That same 285 lb estimated 1RM is Elite at 180 lb, but only around Advanced for a 220 lb lifter because the heavier lifter is moving less weight relative to their size.
Execution also changes the score. A strict rep uses soft knees with no forward knee travel and stops at hamstring-limited depth. If your knees bend more during the set, the lift turns into a Romanian deadlift, which allows more weight and inflates your estimated 1RM — making the score invalid for stiff-leg standards.
This score exposes a different strength quality than knee-dominant pulls. You can have a big conventional deadlift and still fall short here if you lose position when your hamstrings are lengthened or let your knees drift forward under load.
Use your result to see where your hinge strength actually sits, then aim to move up a tier by adding load without losing depth — for example, taking a 0.83× ratio to 1.15× means lifting more weight while holding the same stretched hamstring position and bar path.
Stiff-Leg Deadlift Strength Standards
Stiff-leg deadlift strength standards classify your hinge strength using your estimated 1RM relative to your bodyweight, with Intermediate starting at 0.83× for men and 0.60× for women.
To use the table, start with your bodyweight, then match your estimated 1RM to the correct range. For example, if you weigh 180 lb and your estimated 1RM is 180 lb, that is 1.00× bodyweight, which places you in Intermediate. If you weigh 220 lb with that same 180 lb estimated 1RM, that is 0.82×, which falls in Novice.

|---|---|---|---|---|---|
| 100 lb | <46 | 46–60 | 60–83 | 83–110 | ≥110 |

| 200 lb | <92 | 92–120 | 120–166 | 166–220 | ≥220 |
For another example, if you lift 185 lb for 10 reps, your estimated 1RM is about 247 lb. At 160 lb bodyweight, that is 1.54×, which places you in Elite. At 200 lb bodyweight, that same lift is 1.24×, which falls in Advanced.
Most lifters never reach these numbers with strict hinge mechanics.
This lift behaves differently because once your hips are pushed back and your hamstrings are fully loaded, the bar can only move if you maintain that stretched position while keeping it in contact with your legs—there is no knee drive to help you finish the rep.
If your knees bend more or your range shortens as the set gets heavier, you can move more weight, but the lift is no longer a stiff-leg deadlift. That is why strict hinge position, not just the number on the bar, determines where you actually fall in these standards.
Use your result above, find your bodyweight, and see exactly how many pounds you need to move up to the next level.

How the Stiff-Leg Deadlift Calculator Works
The stiff-leg deadlift calculator estimates your one-rep max using the Epley formula and then compares that number to your bodyweight to determine your strength tier.
When you enter your weight and reps, the calculator uses this equation: Estimated 1RM = weight × (1 + reps ÷ 30). For example, if you lift 225 lb for 8 reps, your estimated 1RM is about 285 lb. At 180 lb bodyweight, that equals 1.58×, which places you in the Elite tier.
The ratio matters because it standardizes your strength across body sizes. That same 285 lb estimated 1RM is Elite at 180 lb, but only about 1.30× at 220 lb bodyweight, which places it in Advanced.
Results can be inflated if your range of motion changes. If your knees bend more or your hips stop moving back as the set gets harder, the bar travels a shorter distance and allows more weight, which increases your estimated 1RM without reflecting true hinge strength.
A strict stiff-leg deadlift keeps limited knee flexion, the bar in contact with your legs, and stops each rep when hamstring tension limits the descent. If those conditions change, the calculation is still mathematically correct, but it no longer represents the same movement.
This is why two sets with the same weight and reps can produce very different real-world strength results. A strict 225 lb × 8 set reflects true hinge strength, while a looser set with more knee bend produces a higher estimate that belongs to a different lift.
Even though hinge depth can vary slightly between lifters, your result is only meaningful if your own reps stay consistent. If your depth or knee angle changes between tests, your numbers may go up without any real increase in hinge strength.
Enter your best strict set above, then use your estimated 1RM and ratio to see your current level and track your progress toward the next tier.
Elite Stiff-Leg Deadlift Strength Levels
Elite stiff-leg deadlift strength starts at 1.47× bodyweight for men and 1.10× for women, with top lifters reaching 1.85× or higher when the lift is performed strictly.
At this level, you can control heavy loads while keeping minimal knee bend and maintaining hamstring tension through the full hinge. For example, a 180 lb lifter with a 265 lb estimated 1RM reaches 1.47×, which marks the start of Elite strength.
Execution matters even more at this level. A strict 265 lb estimated 1RM reflects true hinge strength, while a heavier number achieved with more knee bend or reduced range does not meet Elite standards for this lift. For example, lifting 315 lb with shortened range or increased knee bend may appear stronger, but it no longer represents a stiff-leg deadlift.
What separates Elite from Advanced is the ability to hold the same hinge position under heavier load. Advanced lifters can reach the bottom position, but Elite lifters can stay there, keep the bar close, and stand back up without any change in knee angle or depth.
This is what Elite actually looks like: the bar stays in contact with your legs, your knees remain nearly fixed, and every rep reaches the same hamstring-limited depth even as the weight increases.
Social media often shows heavier lifts labeled as stiff-leg deadlifts, but many of those sets involve more knee bend or shortened range of motion. That allows more weight but changes the movement, which is why strict standards produce lower but more meaningful numbers.
This level also exposes imbalances. A lifter may have a strong conventional deadlift but fall short of Elite here if they cannot maintain position when the hamstrings are fully loaded.
Use your ratio to see how close you are to the Elite threshold, then focus on adding weight without losing hinge position to reach and exceed that level.
Stiff-Leg Deadlift Strength Compared to Other Lifts
Stiff-leg deadlift strength is lower than Romanian and conventional deadlifts because it removes knee drive and places the load entirely on your ability to hold tension in a stretched hinge position.
| Lift | Primary Limiter | Typical Strength Level (× Bodyweight) |
|---|---|---|
| Stiff-Leg Deadlift | Hamstring tension + hinge control | 0.83–1.47× |
| Romanian Deadlift | Hamstrings + some knee flexion | 1.00–1.80× |
| Conventional Deadlift | Quads + hips + back | 1.50–2.50×+ |
For example, a 180 lb lifter with a 285 lb estimated 1RM in the stiff-leg deadlift is at 1.58×, which is Elite. That same lifter might lift 315–365 lb in a Romanian deadlift and 405 lb or more in a conventional deadlift because those lifts allow more knee bend and force contribution from the quads.
Strict vs loose execution makes the difference clear. A strict 285 lb estimated 1RM at 180 lb bodyweight equals 1.58× and reflects true hinge strength, but if that same lifter performs 315 lb with more knee bend and reduced stretch, the number is higher but inflated and no longer represents a stiff-leg deadlift.
Bodyweight still affects how these comparisons are interpreted. A 285 lb stiff-leg deadlift is Elite at 180 lb bodyweight, but only Advanced at 220 lb, even though the absolute weight is the same.
The key difference is where the lift breaks down. If your stiff-leg deadlift lags behind your other pulls, the issue is not total strength—it is your inability to hold position when your hamstrings are fully loaded.
Comparing your stiff-leg deadlift to other lifts helps identify imbalances. If your Romanian or conventional deadlift is much higher but your stiff-leg deadlift stays low, your limitation is hinge control and hamstring strength under stretch.
Use these comparisons to understand where your strength is coming from, then focus on improving your stiff-leg deadlift without relying on knee bend to close the gap.
Additional Exercise Comparisons
Where These Strength Standards Come From
| Source Factor | Adjustment | Reason |
|---|---|---|
| Romanian Deadlift Norms | Baseline | Closest comparable hinge pattern |
| Load Reduction | ~8% lower | Less knee bend reduces load capacity |
| Range of Motion | Hamstring-limited | Stops at stretch, not bar height |
| Execution Standard | Strict hinge only | No knee drift or shortened reps allowed |
Milestones in Stiff-Leg Deadlift Strength
Stiff-leg deadlift milestones are best tracked using bodyweight ratios, with key targets at 1.0×, 1.15×, 1.47×, and 1.85× for men, and proportionally lower thresholds for women.
| Milestone | Men (× Bodyweight) | Women (× Bodyweight) | What It Represents |
|---|---|---|---|
| Baseline Strength | 1.0× | 0.75× | Solid hinge control with consistent depth |
| Advanced Threshold | 1.15× | 0.83× | Strong position under load |
| Elite Entry | 1.47× | 1.10× | Full control at high load |
| Stretch Benchmark | 1.85× | 1.33× | Top-tier hinge strength |
For example, a 180 lb lifter reaching a 180 lb estimated 1RM hits 1.0× bodyweight, which reflects solid baseline hinge strength. Moving to 207 lb (1.15×) places them in Advanced, while reaching 265 lb (1.47×) marks Elite.
Strict execution determines whether these milestones are meaningful. A strict 225 lb estimated 1RM at 180 lb bodyweight equals 1.25× and reflects real progress, but if that same lifter performs 275 lb with more knee bend or shortened range, the higher number is inflated and does not represent a true milestone.
Bodyweight affects how these milestones are interpreted. A 225 lb estimated 1RM is 1.25× at 180 lb bodyweight (Advanced), but only about 1.02× at 220 lb (Intermediate).
Misleading milestones usually come from changes in position. If your knees bend more or your depth shortens as the weight increases, you may reach higher numbers, but you are not progressing in the stiff-leg deadlift.
Real milestone achievement means reaching each ratio with the same hinge depth, fixed knee angle, and bar path. If those do not change as the weight increases, the milestone reflects true improvement.
Use these milestones to track your progress, then focus on reaching each level with strict form before moving to the next.
