What Your Dumbbell Reverse Fly Result Means for Cable Reverse Fly
This calculator turns one strict Dumbbell Reverse 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 | Dumbbell Reverse Fly result | Estimated Dumbbell Reverse Fly max | Predicted Cable Reverse Fly | Expected range | Target level |
|---|---|---|---|---|---|
| 190 lb male | 17.5 lb user-entered load is weight per dumbbell × 8 | 22 lb | 27 lb | 25–27 lb | Novice |
| 150 lb female | 12.5 lb user-entered load is weight per dumbbell × 8 | 16 lb | 19 lb | 17–19 lb | Intermediate |
For the male example, 17.5 lb user-entered load is weight per dumbbell × 8 predicts 27 lb with a 25–27 lb range. The Novice label rates the predicted Cable Reverse Fly result; it does not rate the Dumbbell Reverse Fly result.
How the Dumbbell Reverse Fly to Cable Reverse Fly Conversion Works
The calculator keeps the source and target measurement rules separate: the source entry is user-entered load is weight per dumbbell, while the target result is machine displayed load.
| Step | What the calculator does | Worked example |
|---|---|---|
| 1. Read the source load | Use user-entered load is weight per dumbbell exactly as entered. | 17.5 lb user-entered load is weight per dumbbell × 8 |
| 2. Estimate the source max | Convert the completed set into an estimated source 1RM using the calculator’s approved repetition rule. | 22 lb |
| 3. Map to the target result | Apply the Dumbbell Reverse Fly-to-Cable Reverse Fly mapping (0.818 center coefficient for this male example). | 27 lb |
| 4. Show uncertainty | Calculate the lower and upper ends of the expected transfer range. | 25–27 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.
Dumbbell Reverse Fly to Cable Reverse Fly Conversion Chart
This chart holds the source set at 5 strict reps. Every value is generated by the same calculation as the calculator.
| Dumbbell Reverse Fly result | male estimate | male range | female estimate | female range |
|---|---|---|---|---|
| 7.5 lb user-entered load is weight per dumbbell × 5 | 10 lb | 10–11 lb | 10 lb | 9–10 lb |
| 12.5 lb user-entered load is weight per dumbbell × 5 | 17 lb | 16–18 lb | 17 lb | 16–17 lb |
| 20 lb user-entered load is weight per dumbbell × 5 | 28 lb | 26–28 lb | 27 lb | 25–27 lb |
| 30 lb user-entered load is weight per dumbbell × 5 | 41 lb | 39–42 lb | 41 lb | 38–41 lb |
| 45 lb user-entered load is weight per dumbbell × 5 | 62 lb | 58–63 lb | 61 lb | 56–61 lb |
| 50 lb user-entered load is weight per dumbbell × 5 | 69 lb | 64–70 lb | 68 lb | 63–68 lb |
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 Dumbbell Reverse Fly and Cable Reverse Fly
These exercises share relevant strength demands, but the differences below are why their raw numbers cannot be interchanged.
| Difference | Dumbbell Reverse Fly | Cable Reverse Fly | Why it affects the estimate |
|---|---|---|---|
| Exercise setup and action | isolation pull and horizontal pull | strict cable rear delt reverse fly with two handles and total selected cable resistance | Source: Isolation pull and horizontal pull. 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 requirement | Dumbbell Reverse Fly: dumbbell | Cable Reverse Fly: cable | Source: Dumbbell Reverse Fly: dumbbell. Target: Cable Reverse Fly: cable. The difference changes the strength or repetition capacity being measured. |
| Valid repetition standard | Each rep begins with the lifter holding matched dumbbells, one in each hand. Both dumbbells must travel out to the sides and slightly back through a controlled reverse-fly arc. | 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 | Dumbbell Reverse Fly: strict dumbbell reverse fly. | 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 Dumbbell Reverse Fly-to-Cable Reverse Fly Estimate
Source test: Each rep begins with the lifter holding matched dumbbells, one in each hand. Both dumbbells must travel out to the sides and slightly back through a controlled reverse-fly arc. A valid finish requires both dumbbells to reach the defined reverse-fly end range with stable upper body position and consistent elbow angle.
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 Dumbbell Reverse Fly set | Each rep begins with the lifter holding matched dumbbells, one in each hand. Both dumbbells must travel out to the sides and slightly back through a controlled reverse-fly arc. |
| Use 1 to 10 strict repetitions | Enter one whole-number Dumbbell Reverse Fly set inside the calculator’s approved repetition range. |
| Keep the measurement convention straight | Enter user-entered load is weight per dumbbell. 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 Dumbbell Reverse Fly setup, range, way of recording resistance, and repetition standard consistent. |
Do not substitute Cable Reverse Fly results entered as Dumbbell Reverse Fly results, Dumbbell Reverse Fly repetitions performed with a changed setup or range, partial-range, assisted, or momentum-driven Dumbbell Reverse Fly repetitions, source resistance recorded under a different convention than user-entered load is weight per dumbbell, 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 Dumbbell Reverse 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: 17.5 lb user-entered load is weight per dumbbell × 8 predicts 27 lb with a 25–27 lb range. Use 27 lb as the comparison point, treat 25 lb as the conservative edge, and do not interpret 27 lb as a recommended attempt. Once you record a strict Cable Reverse Fly result, use that direct result instead.
