Romanian Deadlift vs Cable Hamstring Curl Strength Standards

Compare your Romanian deadlift and cable hamstring curl against strength standards for your sex and bodyweight. Enter one recent set of 1–12 reps for each lift to see your estimated one-rep maxes, strength levels, next targets, and which lift you should prioritize.

Use each exercise's canonical input: Total barbell weight for Romanian Deadlift and Displayed machine or stack weight for Cable Hamstring Curl. Use a controlled Romanian deadlift from standing to a consistent depth and back to full standing and a strict, repeatable cable hamstring curl test using the canonical setup, range, and finish rules. You can enter either lift in pounds or kilograms. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.

Romanian Deadlift vs Cable Hamstring Curl Strength Standards by Bodyweight

Use these tables to compare the estimated one-rep max required for the Romanian deadlift and cable hamstring curl to reach the same strength level at each listed bodyweight. They show the targets used by the calculator—not a required difference between your Romanian deadlift and cable hamstring curl.

Choose the men’s or women’s table, find your bodyweight or the closest listed row, then read across to Novice, Intermediate, Advanced, or Elite. Every entry shows Romanian Deadlift / Cable Hamstring Curl, with pounds first and kilograms underneath. For a result based on your exact bodyweight and recent sets, use the calculator above; you do not need to test either true one-rep max.

How Your Romanian Deadlift vs Cable Hamstring Curl Result Is Calculated

The calculator estimates each max, rates it against the standards for that exercise and bodyweight, then compares the two ratings. Here is the complete process.

1. Estimate a one-rep max from each set

For one rep, it uses the weight entered. For 2–12 reps, it runs both formulas and keeps the lower, less aggressive estimate.

  • 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. Estimates are more dependable from clean, difficult, lower-rep sets. See the Back-squat formula validation study and Published discussion of back-squat one-rep-max prediction research.

2. Find the Romanian deadlift strength level

The Romanian deadlift standards use the sex-specific standards from the individual Romanian deadlift tool. Targets begin at 190 lb for men and 150 lb for women, then adjust to your exact bodyweight: reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.

The target rises more slowly than bodyweight so heavier lifters are expected to lift more total weight without requiring strength to increase pound for pound.

3. Find the cable hamstring curl strength level

The standards use the sex-specific targets from the individual Cable Hamstring Curl tool. Targets begin at 190 lb for men and 150 lb for women, then adjust to your exact bodyweight: reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.

The target rises more slowly than bodyweight so heavier lifters are expected to lift more without requiring strength to increase pound for pound.

4. Compare the two results

Each max receives a level from Beginner through Elite. The lower-level lift is the priority. If the levels match, a priority appears only when one lift is at least 10 points farther from its next level. Otherwise, the result is Balanced.

The result shows which lift ranks lower, not why. Technique, fatigue, training history, and set quality can affect it. Age range is recorded anonymously but does not change the standards.

StageWhat happens
Estimate each maxUse the entered weight for 1 rep; for 2–12 reps, keep the lower formula result.
Rate the Romanian deadliftAdjust Romanian deadlift targets to exact bodyweight with the two-thirds rule.
Rate the cable hamstring curlAdjust cable hamstring curl targets to exact bodyweight with the two-thirds rule.
Compare different levelsName the lower-level lift as the priority.
Compare matching levelsUse Balanced unless the difference in progress toward the next level reaches 10 points.

Use the calculator above to see both estimated maxes, strength levels, the priority or Balanced result, and both next-level targets.

How Men’s Romanian Deadlift and Cable Hamstring Curl Standards Differ

How to read both charts: Choose a strength level, find bodyweight along the bottom, and follow that level’s line. Zero means the two standards are equal. Above zero means the cable hamstring curl standard is higher; below zero means the Romanian deadlift standard is higher. On a phone, swipe the chart left and right to inspect the full-size lines and labels. The tables provide the exact pounds and kilograms.

Romanian Deadlift and Cable Hamstring Curl Exercises Used by This Calculator

This calculator uses a barbell Romanian deadlift and a strict cable hamstring curl. Use strict canonical Romanian Deadlift and Cable Hamstring Curl 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 Cable Hamstring Curl

Follow the individual Cable Hamstring Curl 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 Cable Hamstring Curl result

Use each exercise’s canonical input: Total barbell weight for Romanian Deadlift and Displayed machine or stack weight for Cable Hamstring Curl.
