Zottman Curl vs Arnold Press Strength Standards

Compare your zottman curl and arnold press 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 Zottman Curl and Weight per dumbbell for Arnold Press. Use the combined weight of both dumbbells and a strict, repeatable arnold press set that follows the canonical setup, range, and lockout 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.

Zottman Curl vs Arnold Press Strength Standards by Bodyweight

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

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 Zottman Curl / Arnold Press, 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 Zottman Curl vs Arnold Press 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 zottman curl strength level

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

3. Find the arnold press strength level

The standards use the sex-specific targets from the individual Arnold Press 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 zottman curlUse the canonical estimated max and adjust targets to exact bodyweight with the approved two-thirds rule.
Rate the arnold pressAdjust arnold press 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 Zottman Curl and Arnold Press 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 arnold press standard is higher; below zero means the zottman curl 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.
