Reverse Hyperextension vs Barbell Good Morning Strength Standards

Compare your reverse hyperextension and good morning 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: Weight used for Reverse Hyperextension and Total barbell weight for Barbell Good Morning. Use the entered weight for strict Reverse Hyperextension and a raw barbell good morning with the bar on the upper back, minimal knee bend, a braced neutral torso, and a consistent hamstring-limited depth. 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.

Reverse Hyperextension vs Barbell Good Morning Strength Standards by Bodyweight

Use these tables to compare the estimated one-rep max required for the reverse hyperextension and good morning to reach the same strength level at each listed bodyweight. They show the targets used by the calculator—not a required difference between your reverse hyperextension and good morning.

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 Reverse Hyperextension / Good Morning, 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 Reverse Hyperextension vs Barbell Good Morning 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 reverse hyperextension strength level

The standards use the sex-specific thresholds from the individual Reverse Hyperextension 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 larger lifters are expected to lift more without requiring strength to increase pound for pound.

3. Find the good morning strength level

The good morning standards use the sex-specific standards from the individual Barbell Good Morning 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 hinge more total weight 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 reverse hyperextensionUse the canonical estimated max and adjust targets to exact bodyweight with the approved two-thirds rule.
Rate the good morningAdjust good morning 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 Reverse Hyperextension and Barbell Good Morning 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 good morning standard is higher; below zero means the reverse hyperextension 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.

Reverse Hyperextension and Barbell Good Morning Exercises Used by This Calculator

This calculator uses a strict reverse hyperextension test and a barbell good morning. Use strict canonical Reverse Hyperextension and Barbell Good Morning tests. Do not mix variations, assistance, partial range, momentum, or different load conventions.

Use the canonical Reverse Hyperextension setup and load convention

the entered weight for strict Reverse Hyperextension valid Reverse Hyperextension reps Extend the hips by raising the legs or pendulum through the defined range without uncontrolled swinging. A valid finish requires controlled hip extension and return without lumbar overextension or machine rebound Consistent setup, range, and finish quality across the entered set No substituted exercise or assisted reps

Use a raw barbell good morning

Keep the bar on the upper back, hinge backward with minimal knee bend and a braced neutral torso, stop at a repeatable hamstring-limited depth, and return to full standing. Do not enter a safety-bar or Smith-machine good morning, squat-morning, partial hinge, bounced rep, or assisted lift.

Enter one recent Reverse Hyperextension result and one recent Barbell Good Morning result

Use each exercise’s canonical input: Weight used for Reverse Hyperextension and Total barbell weight for Barbell Good Morning.
