Romanian Deadlift vs Bodyweight Back Extension Strength Standards
Compare your Romanian deadlift and bodyweight back extension against strength standards for your sex, age range, and bodyweight. Enter one recent result for each exercise to see your strength levels, next target, and which exercise is the priority.
Enter each exercise in its own canonical metric. Repetitions, seconds, and estimated load remain separate and are compared only by tier and within-tier progress. Use a controlled Romanian deadlift from standing to a consistent depth and back to full standing; use a strict, repeatable bodyweight back extension test using the canonical setup, range, and finish rules. Repetitions are never converted into weight. Each exercise keeps its own measurement type. Age range changes only an exercise whose standards use age.
Romanian Deadlift vs Bodyweight Back Extension Strength Standards by Bodyweight
These tables show the minimum result each exercise needs to reach Novice, Intermediate, Advanced, and Elite. Weight-based standards are shown in pounds and kilograms. Direct-performance standards remain strict repetitions or seconds and show every applicable age range.
Find your bodyweight in the men’s or women’s table, then read across the strength levels. Results measured in weight, repetitions, or seconds are not meant to match and are never converted into one another. Use the calculator for your exact inputs and a direct comparison of the strength levels.

How Your Romanian Deadlift vs Bodyweight Back Extension Result Is Calculated
The two exercises can use different measurements. The calculator rates each result against the standards for that exercise first, then compares the resulting strength levels and progress toward the next level. It never invents a reps-to-weight conversion.
1. Estimate the weight-based result
For Romanian Deadlift, one rep uses the weight entered. For 2–12 reps, the calculator runs both estimates and keeps the lower result.
- Epley: weight × (1 + reps ÷ 30)
- Brzycki: weight × 36 ÷ (37 − reps)
A published back-squat study supports estimated-max prediction under its study conditions. It does not independently validate every exercise or population used by this comparison.
2. Rate the Romanian Deadlift result
The Romanian deadlift standards use the sex-specific standards from the individual Romanian deadlift tool. The target adjusts to bodyweight using reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.
3. Rate the Bodyweight Back Extension result
The canonical repetition thresholds map the strict set to a strength tier; no reps-to-weight conversion is used. The calculator uses one continuous strict bodyweight back extension set scored by repetitions and does not convert the repetitions into an estimated weight.
4. Compare strength level and progress
The lower strength level is the priority. When both exercises reach the same level, a priority appears only when one is at least 10 points farther from its next target. Otherwise, the result is Balanced. Age range changes only the exercise whose standards include age; it remains an analytics field for the other exercise.
| Stage | What happens |
|---|---|
| Rate the Romanian deadlift | Adjust Romanian deadlift targets to exact bodyweight with the two-thirds rule. Measurement: estimated one-rep max. |
| Rate the bodyweight back extension | Rate strict bodyweight back extension repetitions without converting them into weight. Measurement: Strict bodyweight back extension reps. |
| Compare levels | Use each exercise’s own level and next target; do not compare or divide results that use different measurements. |
How Men’s Romanian Deadlift and Bodyweight Back Extension Standards Differ
What the men’s standards show:
Elite weight targets from 120 to 300 lb bodyweight.
Elite direct-performance targets from the youngest to oldest listed age range at 120 lb bodyweight.
Raw repetitions, seconds, and weights are not divided or converted. The calculator compares each exercise’s canonical tier and progress within that tier.
The exact table above is the correct way to inspect direct or unlike measurements. A pounds-difference chart would be invalid because repetitions, seconds, and estimated weight do not share a unit.
How Women’s Romanian Deadlift and Bodyweight Back Extension Standards Differ
What the women’s standards show:
Elite weight targets from 100 to 240 lb bodyweight.
Elite direct-performance targets from the youngest to oldest listed age range at 100 lb bodyweight.
Raw repetitions, seconds, and weights are not divided or converted. The calculator compares each exercise’s canonical tier and progress within that tier.
Use the calculator to apply the correct age range and exact bodyweight before comparing the two strength levels.
Romanian Deadlift and Bodyweight Back Extension Exercises Used by This Calculator
This calculator uses a barbell Romanian deadlift and a strict bodyweight back extension. Use strict canonical Romanian Deadlift and Bodyweight Back Extension tests. Do not mix variations, assistance, partial range, momentum, or different load conventions.
Use a standing-start barbell Romanian deadlift
Begin each set standing with the bar. Keep a small, consistent knee bend, push the hips back, and lower the bar close to the legs until you reach a repeatable hamstring-limited depth. Return to full standing. Do not enter a conventional deadlift, stiff-leg deadlift, partial pull, machine variation, or another hinge exercise.
Use a strict, repeatable Bodyweight Back Extension
Follow the individual Bodyweight Back Extension calculator’s canonical setup, load convention, range of motion, and finish rules. Keep the same setup when retesting.
Enter one recent Romanian Deadlift result and one recent Bodyweight Back Extension result
Enter each exercise in its own canonical metric. Repetitions, seconds, and estimated load remain separate and are compared only by tier and within-tier progress.
