Dumbbell Lateral Raise vs Machine Reverse Fly Strength Standards

Compare your dumbbell lateral raise and machine reverse fly 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.

Enter the canonical working weight and a whole number of strict repetitions for each exercise. Pounds and kilograms can be mixed. Use a bilateral dumbbell lateral raise with a stable upright torso, consistent elbow angle, both upper arms reaching at least shoulder height, and a controlled lowering phase and a strict dedicated reverse-fly-machine set with stable chest support, symmetrical full range, and controlled return. 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.

Dumbbell Lateral Raise vs Machine Reverse Fly Strength Standards by Bodyweight

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

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 Dumbbell Lateral Raise / Machine Reverse Fly, 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 Dumbbell Lateral Raise vs Machine Reverse Fly 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 dumbbell lateral raise strength level

The standards use the sex-specific bilateral dumbbell lateral raise thresholds from the individual 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 calculator first treats the set as two matched dumbbells, while the target rises more slowly than bodyweight.

3. Find the machine reverse fly strength level

The standards use the sex-specific strength levels from the individual Machine Reverse Fly 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 move more machine resistance 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 dumbbell lateral raiseUse two-dumbbell load and adjust targets to exact bodyweight with the two-thirds rule.
Rate the machine reverse flyAdjust machine reverse fly targets to exact bodyweight with the two-thirds rule while preserving bilateral machine resistance.
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 Dumbbell Lateral Raise and Machine Reverse Fly 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 machine reverse fly standard is higher; below zero means the dumbbell lateral raise 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.

Dumbbell Lateral Raise and Machine Reverse Fly Exercises Used by This Calculator

This calculator uses a strict bilateral dumbbell lateral raise and a strict machine reverse fly. Use strict canonical Dumbbell Lateral Raise and Machine Reverse Fly tests. Do not mix variations, assistance, partial range, momentum, or different load conventions.

Raise two matched dumbbells to shoulder height without momentum

Enter the weight of one dumbbell. Keep the torso upright and elbow angle consistent, raise both upper arms symmetrically to at least shoulder height, and lower under control. Do not enter combined pair weight, cable or machine raises, upright-row or front-raise hybrids, partial reps, swing reps, shrug-driven reps, or momentum-assisted reps.

Enter bilateral machine resistance and preserve the guided fly path

Use one dedicated reverse-fly machine with stable chest support and a symmetrical controlled range. Enter selected or loaded bilateral resistance. Do not count rows, other fly variations, face pulls, shrugs, bounce, rebound, torso heave, or partial reps.

Enter one recent Dumbbell Lateral Raise result and one recent Machine Reverse Fly result
