Machine Reverse Fly to Cable Rear Delt Row Conversion Calculator

This Machine Reverse Fly to Cable Rear Delt Row Conversion calculator estimates Cable Rear Delt Row Conversion strength from Machine Reverse Fly performance.

Enter your sex, bodyweight, and Machine Reverse Fly performance to see your Cable Rear Delt Row Conversion estimate, expected range, strength tier, and ratio to bodyweight.

The calculator uses the conversion model for this tool to translate Machine Reverse Fly performance into the Cable Rear Delt Row Conversion estimate. Use the result as a planning estimate, not a guaranteed max or attempt recommendation.

What Your Machine Reverse Fly Result Means for Cable Rear Delt Row

This calculator turns one strict Machine Reverse Fly result into a predicted Cable Rear Delt Row 1RM. The result gives you a center estimate, a planning range, and a strength level for the Cable Rear Delt Row only.

ExampleMachine Reverse Fly resultEstimated Machine Reverse Fly maxPredicted Cable Rear Delt RowExpected rangeTarget level
190 lb male40 lb selected or loaded machine resistance for the two-sided set × 850 lb50 lb48–56 lbNovice

For the male example, 40 lb selected or loaded machine resistance for the two-sided set × 8 predicts 50 lb with a 48–56 lb range. The Novice label rates the predicted Cable Rear Delt Row result; it does not rate the Machine Reverse Fly result.

How the Machine Reverse Fly to Cable Rear Delt Row Conversion Works

The calculator keeps the source and target measurement rules separate: the source entry is selected or loaded machine resistance for the two-sided set, while the target result is machine displayed load.

StepWhat the calculator doesWorked example
1. Read the source loadUse selected or loaded machine resistance for the two-sided set exactly as entered.40 lb selected or loaded machine resistance for the two-sided set × 8
2. Estimate the source maxConvert the completed set into an estimated source 1RM using the calculator’s approved repetition rule.50 lb
3. Map to the target resultApply the Machine Reverse Fly-to-Cable Rear Delt Row mapping (1.000 center coefficient for this male example).50 lb
4. Show uncertaintyCalculate the lower and upper ends of the expected transfer range.48–56 lb
5. Rate the targetClassify the unrounded center against Cable Rear Delt Row 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 Rear Delt Row performance to learn your actual result.

Cable Rear Delt Row Strength Standards

The calculator rates only the predicted Cable Rear Delt Row result. These reference standards use the same bodyweights and sex profiles as the examples above.

Cable Rear Delt Row level190 lb male: machine displayed load150 lb female: machine displayed load
BeginnerBelow 35 lbBelow 17 lb
Novice35–53 lb17–26 lb
Intermediate54–75 lb27–41 lb
Advanced76–102 lb42–56 lb
Elite103 lb or more57 lb or more
Stretch benchmark129 lb75 lb

The live calculator resolves the target standard for the bodyweight entered. The source exercise keeps its own separate standards.

Key Differences Between Machine Reverse Fly and Cable Rear Delt Row

These exercises share relevant strength demands, but the differences below are why their raw numbers cannot be interchanged.

DifferenceMachine Reverse FlyCable Rear Delt RowWhy it affects the estimate
Movement and setupMachine Reverse Fly: strict Machine Reverse Fly.Cable Rear Delt Row: strict Cable Rear Delt Row.The starting position and movement path determine the leverage and muscles that can contribute to a valid repetition.
Equipment and recorded resistanceSelected or weighted machine resistance for the both sides together set, not per-arm load by default, not dumbbell load, not cable-stack load from cable reverse flyes, not row load, and not a free-weight equivalent.The selected cable stack or weighted cable resistance used for the strict rear-delt row, not per-arm load, dumbbell load, barbell load, or machine row load using cable station.The equipment and the way resistance is recorded make the displayed numbers unsuitable for direct substitution.
Valid repetition standardEach 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.Each rep begins in the correct Cable Rear Delt Row setup with the implement, machine, cable, or kettlebell position controlled before the counted set starts.A set only belongs in the conversion when it follows the source test, and the prediction only represents the stated target test.
How the result is scoredestimated one-rep max compared with Machine Reverse Fly standards for sex and bodyweightestimated one-rep max compared with Cable Rear Delt Row standards for sex and bodyweightThe source and target retain separate scoring rules, so the target classification cannot be reused as a rating of the source set.

Getting and Using a Useful Machine Reverse Fly-to-Cable Rear Delt Row Estimate

Source test: 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.

Target represented: Each rep begins in the correct Cable Rear Delt Row setup with the implement, machine, cable, or kettlebell position controlled before the counted set starts. The movement must travel through a clear, repeatable range matching this force pattern: cable row pulled toward the upper chest or shoulder line with elbows flared to bias rear delts and upper back.

Before calculatingWhat to do
Use a valid Machine Reverse Fly setEach 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.
Use 1 to 10 strict repetitionsEnter one whole-number Machine Reverse Fly set inside the calculator’s approved repetition range.
Keep the measurement convention straightEnter selected or loaded machine resistance for the two-sided set. Read the target as machine displayed load.
Use the range for planningStart Cable Rear Delt Row practice near the conservative end and use the center as the main comparison point.
Retest under the same conditionsKeep the Machine Reverse Fly setup, range, way of recording resistance, and repetition standard consistent.

Do not substitute Cable Rear Delt Row results entered as Machine Reverse Fly results, Machine Reverse Fly repetitions performed with a changed setup or range, partial-range, assisted, or momentum-driven Machine Reverse Fly repetitions, source resistance recorded under a different convention than selected or loaded machine resistance for the two-sided set, multiple sets combined into one repetition total. Those are different tests, so their numbers do not belong in this conversion.

Result componentHow to use it
Predicted centerUse it as the main comparison point for the Machine Reverse Fly-to-Cable Rear Delt Row estimate.
Low end of rangeUse it as the conservative reference when beginning or resuming Cable Rear Delt Row practice.
High end of rangeTreat it as possible context—not a guaranteed result or attempt recommendation.
Cable Rear Delt Row strength levelUse it only to understand where the predicted result falls against Cable Rear Delt Row standards.
Direct Cable Rear Delt Row resultReplace the prediction with the actual result once Cable Rear Delt Row has been performed under the stated test.

Example: 40 lb selected or loaded machine resistance for the two-sided set × 8 predicts 50 lb with a 48–56 lb range. Use 50 lb as the comparison point, treat 48 lb as the conservative edge, and do not interpret 56 lb as a recommended attempt. Once you record a strict Cable Rear Delt Row result, use that direct result instead.

Use a direct standards tool when you have performed the exercise itself. Use neighboring tools to answer a different question—not to overwrite this conversion.
