What Your Log Deadlift Result Means for Barbell Stiff-Leg Deadlift
This calculator turns one strict Log Deadlift result into a predicted Barbell Stiff-Leg Deadlift 1RM. The result gives you a center estimate, a planning range, and a strength level for the Barbell Stiff-Leg Deadlift only.
| Example | Log Deadlift result | Estimated Log Deadlift max | Predicted Barbell Stiff-Leg Deadlift | Expected range | Target level |
|---|---|---|---|---|---|
| 190 lb male | 250 lb total log load including implement and plates × 8 | 310 lb | 176 lb | 157–210 lb | Intermediate |
| 150 lb female | 145 lb total log load including implement and plates × 8 | 180 lb | 97 lb | 90–111 lb | Intermediate |
For the male example, 250 lb total log load including implement and plates × 8 predicts 176 lb with a 157–210 lb range. The Intermediate label rates the predicted Barbell Stiff-Leg Deadlift result; it does not rate the Log Deadlift result.
How the Log Deadlift to Barbell Stiff-Leg Deadlift Conversion Works
The calculator keeps the source and target measurement rules separate: the source entry is total log load including implement and plates, while the target result is total barbell load.
| Step | What the calculator does | Worked example |
|---|---|---|
| 1. Read the source load | Use total log load including implement and plates exactly as entered. | 250 lb total log load including implement and plates × 8 |
| 2. Estimate the source max | Convert the completed set into an estimated source 1RM using the calculator’s approved repetition rule. | 310 lb |
| 3. Map to the target result | Apply the Log Deadlift-to-Barbell Stiff-Leg Deadlift mapping (1.768 center coefficient for this male example). | 176 lb |
| 4. Show uncertainty | Calculate the lower and upper ends of the expected transfer range. | 157–210 lb |
| 5. Rate the target | Classify the unrounded center against Barbell Stiff-Leg Deadlift standards. | Intermediate |
The conversion matches reviewed strength levels for these two exercises. It does not claim that their loads, repetitions, equipment, or execution are interchangeable—or that the center is guaranteed.

The range reflects transfer uncertainty. Use the center to compare or plan, and use direct Barbell Stiff-Leg Deadlift performance to learn your actual result.
Barbell Stiff-Leg Deadlift Strength Standards
The calculator rates only the predicted Barbell Stiff-Leg Deadlift result. These reference standards use the same bodyweights and sex profiles as the examples above.
| Barbell Stiff-Leg Deadlift level | 190 lb male: total barbell load | 150 lb female: total barbell load |
|---|---|---|
| Beginner | Below 124 lb | Below 69 lb |
| Novice | 124–157 lb | 69–90 lb |
| Intermediate | 158–218 lb | 91–124 lb |
| Advanced | 219–279 lb | 125–165 lb |
| Elite | 280 lb or more | 166 lb or more |
| Stretch benchmark | 352 lb | 200 lb |
The live calculator resolves the target standard for the bodyweight entered. The source exercise keeps its own separate standards.
Key Differences Between Log Deadlift and Barbell Stiff-Leg Deadlift
These exercises share relevant strength demands, but the differences below are why their raw numbers cannot be interchanged.
| Difference | Log Deadlift | Barbell Stiff-Leg Deadlift | Why it affects the estimate |
|---|---|---|---|
| Movement and setup | Log Deadlift: strict log deadlift. | Barbell Stiff-Leg Deadlift: floor-start barbell hip hinge with minimal knee bend | The starting position and movement path determine the leverage and muscles that can contribute to a valid repetition. |
| Equipment and recorded resistance | Total log load including implement and plates. | Total barbell weight. | The equipment and the way resistance is recorded make the displayed numbers unsuitable for direct substitution. |
| Primary performance demands | the exercise-specific exercise setup and action, repeatable full-range execution, stable positioning | floor-start hip-hinge strength, hamstring and glute force, bracing with minimal knee bend | A different mix of force, stability, mobility, and repetition endurance can move actual target performance away from the estimate. |
| Valid repetition standard | Each rep begins with the log motionless on the floor. Pull the log to full standing lockout in one controlled movement without cleaning or rolling it up the body. | Start the bar on the floor with only a soft knee bend, hinge the hips back while keeping the legs nearly straight and bar close, stand fully upright, and reset the bar motionless on the floor between reps. | A set only belongs in the conversion when it follows the source test, and the prediction only represents the stated target test. |
Getting and Using a Useful Log Deadlift-to-Barbell Stiff-Leg Deadlift Estimate
Source test: Each rep begins with the log motionless on the floor. Pull the log to full standing lockout in one controlled movement without cleaning or rolling it up the body. A valid finish requires hips and knees extended, shoulders controlled, and the log held securely without hitching or support.
Target represented: Start the bar on the floor with only a soft knee bend, hinge the hips back while keeping the legs nearly straight and bar close, stand fully upright, and reset the bar motionless on the floor between reps.
| Before calculating | What to do |
|---|---|
| Use a valid Log Deadlift set | Each rep begins with the log motionless on the floor. Pull the log to full standing lockout in one controlled movement without cleaning or rolling it up the body. |
| Use 1 to 10 strict repetitions | Enter one whole-number Log Deadlift set inside the calculator’s approved repetition range. |
| Keep the measurement convention straight | Enter total log load including implement and plates. Read the target as total barbell load. |
| Use the range for planning | Start Barbell Stiff-Leg Deadlift practice near the conservative end and use the center as the main comparison point. |
| Retest under the same conditions | Keep the Log Deadlift setup, range, way of recording resistance, and repetition standard consistent. |
Do not substitute Barbell Stiff-Leg Deadlift results entered as Log Deadlift results, Log Deadlift repetitions performed with a changed setup or range, partial-range, assisted, or momentum-driven Log Deadlift repetitions, source resistance recorded under a different convention than total log load including implement and plates, multiple sets combined into one repetition total. Those are different tests, so their numbers do not belong in this conversion.
| Result component | How to use it |
|---|---|
| Predicted center | Use it as the main comparison point for the Log Deadlift-to-Barbell Stiff-Leg Deadlift estimate. |
| Low end of range | Use it as the conservative reference when beginning or resuming Barbell Stiff-Leg Deadlift practice. |
| High end of range | Treat it as possible context—not a guaranteed result or attempt recommendation. |
| Barbell Stiff-Leg Deadlift strength level | Use it only to understand where the predicted result falls against Barbell Stiff-Leg Deadlift standards. |
| Direct Barbell Stiff-Leg Deadlift result | Replace the prediction with the actual result once Barbell Stiff-Leg Deadlift has been performed under the stated test. |
Example: 250 lb total log load including implement and plates × 8 predicts 176 lb with a 157–210 lb range. Use 176 lb as the comparison point, treat 157 lb as the conservative edge, and do not interpret 210 lb as a recommended attempt. Once you record a strict Barbell Stiff-Leg Deadlift result, use that direct result instead.
