Dumbbell Lateral Raise vs Single Arm Dumbbell Rear Delt Fly Strength Standards
Compare your dumbbell lateral raise and single arm dumbbell rear delt fly against strength standards for your sex and bodyweight. Enter 1–12 reps for estimated one-rep maxes, strength levels, next targets, and priority.
Use each exercise's canonical input: Weight per dumbbell for Dumbbell Lateral Raise and Total external load for Single Arm Dumbbell Rear Delt Fly. Testing: 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; entered load is the weight of the one dumbbell moved by one arm at a time.. Pounds or kilograms. Heavier lift is not automatically the stronger one.

How Your Dumbbell Lateral Raise vs Single Arm Dumbbell Rear Delt 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 single arm dumbbell rear delt fly strength level
The standards use the sex-specific thresholds from the individual Single Arm Dumbbell Rear Delt 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 larger 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.
| Stage | What happens |
|---|---|
| Estimate each max | Use the entered weight for 1 rep; for 2–12 reps, keep the lower formula result. |
| Rate the dumbbell lateral raise | Use two-dumbbell load and adjust targets to exact bodyweight with the two-thirds rule. |
| Rate the single arm dumbbell rear delt fly | Use the canonical estimated max and adjust targets to exact bodyweight with the approved two-thirds rule. |
| Compare different levels | Name the lower-level lift as the priority. |
| Compare matching levels | Use 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 Single Arm Dumbbell Rear Delt 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 single arm dumbbell rear delt 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.
What the men’s data shows:
The standards come closest at 120 lb.
Novice, Intermediate, Advanced, and Elite at every displayed bodyweight.
8.1 → 15.4 kg from 120 to 300 lb bodyweight.
How to read the table: Every number is the single arm dumbbell rear delt fly standard minus the dumbbell lateral raise standard. A plus sign means the single arm dumbbell rear delt fly standard is higher. A minus sign means the dumbbell lateral raise standard is higher.

Dumbbell Lateral Raise and Single Arm Dumbbell Rear Delt Fly Exercises Used by This Calculator
This calculator uses a strict bilateral dumbbell lateral raise and a strict single arm dumbbell rear delt fly test. Use strict canonical Dumbbell Lateral Raise and Single Arm Dumbbell Rear Delt 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.
Use the canonical Single Arm Dumbbell Rear Delt Fly setup and load convention
entered load is the weight of the one dumbbell moved by one arm at a time. total valid reps across both arms combined Move the dumbbell outward and back through shoulder horizontal abduction to a clear rear-delt fly top range, then lower under control to the same bottom position without rowing. A valid finish requires posterior-shoulder control without shrug-only motion, lat-row mechanics, excessive arm bend, trunk heave, or swinging. Consistent setup, range, and finish quality across the entered set No substituted exercise or assisted reps
Enter one recent Dumbbell Lateral Raise result and one recent Single Arm Dumbbell Rear Delt Fly result
