What Your Single Arm Dumbbell Rear Delt Fly Result Means for Cable Reverse Fly
This calculator turns one strict Single Arm Dumbbell Rear Delt Fly result into a predicted Cable Reverse Fly 1RM. The result gives you a center estimate, a planning range, and a strength level for the Cable Reverse Fly only.
| Example | Single Arm Dumbbell Rear Delt Fly result | Estimated Single Arm Dumbbell Rear Delt Fly max | Predicted Cable Reverse Fly | Expected range | Target level |
|---|---|---|---|---|---|
| 190 lb male | 10 lb one dumbbell moved by one arm at a time × 8 | 12 lb | 25 lb | 23–25 lb | Novice |
| 150 lb female | 5 lb one dumbbell moved by one arm at a time × 8 | 6 lb | 14 lb | 12–15 lb | Novice |
For the male example, 10 lb one dumbbell moved by one arm at a time × 8 predicts 25 lb with a 23–25 lb range. The Novice label rates the predicted Cable Reverse Fly result; it does not rate the Single Arm Dumbbell Rear Delt Fly result.
How the Single Arm Dumbbell Rear Delt Fly to Cable Reverse Fly Conversion Works
The calculator keeps the source and target measurement rules separate: the source entry is weight of the one dumbbell moved by one arm at a time, while the target result is machine displayed load.
| Step | What the calculator does | Worked example |
|---|---|---|
| 1. Read the source load | Use weight of the one dumbbell moved by one arm at a time exactly as entered. | 10 lb one dumbbell moved by one arm at a time × 8 |
| 2. Estimate the source max | Convert the completed set into an estimated source 1RM using the calculator’s approved repetition rule. | 12 lb |
| 3. Map to the target result | Apply the Single Arm Dumbbell Rear Delt Fly-to-Cable Reverse Fly mapping (0.500 center coefficient for this male example). | 25 lb |
| 4. Show uncertainty | Calculate the lower and upper ends of the expected transfer range. | 23–25 lb |
| 5. Rate the target | Classify the unrounded center against Cable Reverse Fly standards. | Novice |
The conversion matches reviewed strength levels for these two exercises. It does not claim that their loads, repetitions, equipment, or execution are interchangeable—or that the center is guaranteed.

The range reflects transfer uncertainty. Use the center to compare or plan, and use direct Cable Reverse Fly performance to learn your actual result.
Cable Reverse Fly Strength Standards
The calculator rates only the predicted Cable Reverse Fly result. These reference standards use the same bodyweights and sex profiles as the examples above.
| Cable Reverse Fly level | 190 lb male: machine displayed load | 150 lb female: machine displayed load |
|---|---|---|
| Beginner | Below 16 lb | Below 10 lb |
| Novice | 16–26 lb | 10–15 lb |
| Intermediate | 27–41 lb | 16–24 lb |
| Advanced | 42–60 lb | 25–36 lb |
| Elite | 61 lb or more | 37 lb or more |
| Stretch benchmark | 76 lb | 45 lb |
The live calculator resolves the target standard for the bodyweight entered. The source exercise keeps its own separate standards.
Key Differences Between Single Arm Dumbbell Rear Delt Fly and Cable Reverse Fly
These exercises share relevant strength demands, but the differences below are why their raw numbers cannot be interchanged.
| Difference | Single Arm Dumbbell Rear Delt Fly | Cable Reverse Fly | Why it affects the estimate |
|---|---|---|---|
| Exercise setup and action | single arm dumbbell rear delt fly using dumbbell | strict cable rear-delt reverse fly with two handles and total selected cable resistance | Source: Single arm dumbbell rear delt fly using dumbbell. Target: Strict cable rear-delt reverse fly with two handles and total selected cable resistance. The difference changes the strength or repetition capacity being measured. |
| Equipment and load convention | dumbbell; Total external weight | cable; Displayed machine or stack weight | The exercises record resistance differently, so equal-looking numbers do not represent equal performance. |
| Valid repetition standard | Each rep begins with the upper body hinged or chest-supported, one dumbbell controlled below the working shoulder, shoulder set, elbow softly bent, and trunk or support position stable. | Each rep begins with one cable handle in each hand on a dual cable station or equivalent functional trainer. Both handles must move out and back through a controlled reverse-fly path. | Changing either repetition standard changes the exercise being compared and weakens the usefulness of the estimate. |
| Movement and setup | Single Arm Dumbbell Rear Delt Fly: strict single-arm dumbbell rear delt fly with a hinged or supported upper body and a long-lever posterior-shoulder path. | Cable Reverse Fly: strict Cable Reverse Fly with one cable handle in each hand and both arms moving through a matched rear-delt fly path. | The starting position and movement path determine the leverage and muscles that can contribute to a valid repetition. |
Getting and Using a Useful Single Arm Dumbbell Rear Delt Fly-to-Cable Reverse Fly Estimate
Source test: Each rep begins with the upper body hinged or chest-supported, one dumbbell controlled below the working shoulder, shoulder set, elbow softly bent, and trunk or support position stable. 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.
Target represented: Each rep begins with one cable handle in each hand on a dual cable station or equivalent functional trainer. Both handles must move out and back through a controlled reverse-fly path. A valid rearward finish requires a clear controlled reverse-fly end range, stable upper body position, stable shoulders, controlled wrists, and no row, shrug, or upper body-assisted completion.
| Before calculating | What to do |
|---|---|
| Use a valid Single Arm Dumbbell Rear Delt Fly set | Each rep begins with the upper body hinged or chest-supported, one dumbbell controlled below the working shoulder, shoulder set, elbow softly bent, and trunk or support position stable. |
| Use 1 to 10 strict repetitions | Enter one whole-number Single Arm Dumbbell Rear Delt Fly set inside the calculator’s approved repetition range. |
| Keep the measurement convention straight | Enter weight of the one dumbbell moved by one arm at a time. Read the target as machine displayed load. |
| Use the range for planning | Start Cable Reverse Fly practice near the conservative end and use the center as the main comparison point. |
| Retest under the same conditions | Keep the Single Arm Dumbbell Rear Delt Fly setup, range, way of recording resistance, and repetition standard consistent. |
Do not substitute Cable Reverse Fly results entered as Single Arm Dumbbell Rear Delt Fly results, Single Arm Dumbbell Rear Delt Fly repetitions performed with a changed setup or range, partial-range, assisted, or momentum-driven Single Arm Dumbbell Rear Delt Fly repetitions, source resistance recorded under a different convention than weight of the one dumbbell moved by one arm at a time, multiple sets combined into one repetition total. Those are different tests, so their numbers do not belong in this conversion.
| Result component | How to use it |
|---|---|
| Predicted center | Use it as the main comparison point for the Single Arm Dumbbell Rear Delt Fly-to-Cable Reverse Fly estimate. |
| Low end of range | Use it as the conservative reference when beginning or resuming Cable Reverse Fly practice. |
| High end of range | Treat it as possible context—not a guaranteed result or attempt recommendation. |
| Cable Reverse Fly strength level | Use it only to understand where the predicted result falls against Cable Reverse Fly standards. |
| Direct Cable Reverse Fly result | Replace the prediction with the actual result once Cable Reverse Fly has been performed under the stated test. |
Example: 10 lb one dumbbell moved by one arm at a time × 8 predicts 25 lb with a 23–25 lb range. Use 25 lb as the comparison point, treat 23 lb as the conservative edge, and do not interpret 25 lb as a recommended attempt. Once you record a strict Cable Reverse Fly result, use that direct result instead.
