Cable Reverse Fly to Machine Reverse Fly Conversion Calculator
This Cable Reverse Fly to Machine Reverse Fly Conversion calculator estimates Machine Reverse Fly Conversion strength from Cable Reverse Fly performance.
Enter your sex, bodyweight, and Cable Reverse Fly performance to see your Machine Reverse Fly Conversion estimate, expected range, strength tier, and ratio to bodyweight.
The calculator uses the conversion model for this tool to translate Cable Reverse Fly performance into the Machine Reverse Fly Conversion estimate. Use the result as a planning estimate, not a guaranteed max or attempt recommendation.
What Your Cable Reverse Fly Result Means for Machine Reverse Fly
This calculator turns one strict Cable Reverse Fly result into a predicted Machine Reverse Fly 1RM. The result gives you a center estimate, a planning range, and a strength level for the Machine Reverse Fly only.
| Example | Cable Reverse Fly result | Estimated Cable Reverse Fly max | Predicted Machine Reverse Fly | Expected range | Target level |
|---|---|---|---|---|---|
| 190 lb male | 22.5 lb displayed machine or stack weight × 8 | 28 lb | 51 lb | 47–56 lb | Intermediate |
| 150 lb female | 12.5 lb displayed machine or stack weight × 8 | 16 lb | 22 lb | 21–23 lb | Intermediate |
For the male example, 22.5 lb displayed machine or stack weight × 8 predicts 51 lb with a 47–56 lb range. The Intermediate label rates the predicted Machine Reverse Fly result; it does not rate the Cable Reverse Fly result.
How the Cable Reverse Fly to Machine Reverse Fly Conversion Works
The calculator keeps the source and target measurement rules separate: the source entry is displayed machine or stack weight, while the target result is selected machine resistance.
| Step | What the calculator does | Worked example |
|---|---|---|
| 1. Read the source load | Use displayed machine or stack weight exactly as entered. | 22.5 lb displayed machine or stack weight × 8 |
| 2. Estimate the source max | Convert the completed set into an estimated source 1RM using the calculator’s approved repetition rule. | 28 lb |
| 3. Map to the target press | Apply the Cable Reverse Fly-to-Machine Reverse Fly mapping (0.550 center coefficient for this male example). | 51 lb |
| 4. Show uncertainty | Calculate the lower and upper ends of the expected transfer range. | 47–56 lb |
| 5. Rate the target | Classify the unrounded center against Machine Reverse Fly standards. | Intermediate |
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.
Cable Reverse Fly to Machine 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.
| Cable Reverse Fly result | male estimate | male range | female estimate | female range |
|---|---|---|---|---|
| 10 lb displayed machine or stack weight × 5 | 20 lb | 19–23 lb | 16 lb | 15–17 lb |
| 12.5 lb displayed machine or stack weight × 5 | 26 lb | 24–28 lb | 20 lb | 19–21 lb |
| 25 lb displayed machine or stack weight × 5 | 51 lb | 48–56 lb | 40 lb | 38–42 lb |
| 35 lb displayed machine or stack weight × 5 | 72 lb | 67–79 lb | 56 lb | 53–59 lb |
| 55 lb displayed machine or stack weight × 5 | 113 lb | 105–124 lb | 88 lb | 83–93 lb |
| 60 lb displayed machine or stack weight × 5 | 123 lb | 115–135 lb | 96 lb | 90–101 lb |
The range reflects transfer uncertainty. Use the center to compare or plan, and use direct Machine Reverse Fly performance to learn your actual result.
Machine Reverse Fly Strength Standards
The calculator rates only the predicted Machine Reverse Fly result. These reference standards use the same bodyweights and sex profiles as the examples above.
| Machine Reverse Fly level | 190 lb male: selected machine resistance | 150 lb female: selected machine resistance |
|---|---|---|
| Beginner | Below 31 lb | Below 13 lb |
| Novice | 31–49 lb | 13–21 lb |
| Intermediate | 50–76 lb | 22–36 lb |
| Advanced | 77–106 lb | 37–51 lb |
| Elite | 107 lb or more | 52 lb or more |
| Stretch benchmark | 129 lb | 65 lb |
The live calculator resolves the target standard for the bodyweight entered. The source exercise keeps its own separate standards.
Key Differences Between Cable Reverse Fly and Machine Reverse Fly
These exercises share relevant strength demands, but the differences below are why their raw numbers cannot be interchanged.
| Difference | Cable Reverse Fly | Machine Reverse Fly | Why it affects the estimate |
|---|---|---|---|
| Resistance path | uses cable resistance through the stated cable reverse-fly path | uses a dedicated machine’s guided reverse-fly arc | The exercises record resistance differently, so equal-looking numbers do not represent equal performance. |
| Support requirement | uses the cable tool’s prescribed stance and body stabilization | uses the machine’s seat and chest pad or equivalent support | Source: Uses the cable tool’s prescribed stance and body stabilization. Target: Uses the machine’s seat and chest pad or equivalent support. The difference changes the strength or repetition capacity being measured. |
| Entered load | uses displayed machine or stack weight under the cable tool’s convention | uses selected machine resistance | The exercises record resistance differently, so equal-looking numbers do not represent equal performance. |
| Valid repetition standard | 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. | Each rep begins seated on a dedicated machine reverse fly, rear-delt fly, or reverse-pec-deck-style machine. Both machine arms 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. |
Getting and Using a Useful Cable Reverse Fly-to-Machine Reverse Fly Estimate
Source test: 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.
Target represented: Each rep begins seated on a dedicated machine reverse fly, rear-delt fly, or reverse-pec-deck-style machine. Both machine arms must move out and back through a controlled reverse-fly path. A valid finish requires both handles or pads to reach the machine’s defined rearward range under control with stable upper body position and symmetrical arm movement.
| Before calculating | What to do |
|---|---|
| Use a valid Cable Reverse Fly set | 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. |
| Use 1 to 10 strict repetitions | Enter one whole-number Cable Reverse Fly set inside the calculator’s approved repetition range. |
| Keep the measurement convention straight | Enter displayed machine or stack weight. Read the target as selected machine resistance. |
| Use the range for planning | Start Machine Reverse Fly practice near the conservative end and use the center as the main comparison point. |
| Retest under the same conditions | Keep the Cable Reverse Fly setup, range, way of recording resistance, and repetition standard consistent. |
Do not substitute Machine Reverse Fly results entered as Cable Reverse Fly results, Cable Reverse Fly repetitions performed with a changed setup or range, partial-range, assisted, or momentum-driven Cable Reverse Fly repetitions, resistance recorded differently from displayed machine or stack weight, 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 Cable Reverse Fly-to-Machine Reverse Fly estimate. |
| Low end of range | Use it as the conservative reference when beginning or resuming Machine Reverse Fly practice. |
| High end of range | Treat it as possible context—not a guaranteed result or attempt recommendation. |
| Machine Reverse Fly strength level | Use it only to understand where the predicted result falls against Machine Reverse Fly standards. |
| Direct Machine Reverse Fly result | Replace the prediction with the actual result once Machine Reverse Fly has been performed under the stated test. |
Example: 22.5 lb displayed machine or stack weight × 8 predicts 51 lb with a 47–56 lb range. Use 51 lb as the comparison point, treat 47 lb as the conservative edge, and do not interpret 56 lb as a recommended attempt. Once you record a strict Machine Reverse Fly result, use that direct result instead.
