Machine Reverse Fly Strength Standards Calculator
Compare your Machine Reverse Fly strength with Endura's strength standards for men and women at your bodyweight. A useful benchmark for a good one-rep max is our Intermediate standard: approximately 50 lb at 190 lb for a man and 22 lb at 150 lb for a woman.
How does your best lift compare? Enter your bodyweight, the selected or loaded machine resistance for the bilateral machine reverse fly set, and the reps you completed below. The calculator estimates your one-rep max and shows your strength level for your bodyweight. Use the exercise-specific approved repetition convention.
The calculator compares that estimated one-rep max with the Machine Reverse Fly standards for your sex at your bodyweight. It preserves the calculator's existing equations, thresholds, and input meanings; the benchmark is a comparison target, not a working-set prescription.
Understanding Your Machine Reverse Fly Strength Score
Your Machine Reverse Fly strength score is Estimated 1RM divided by bodyweight, using strict bilateral seated rear-delt machine execution. The score ranks guided posterior-shoulder isolation strength, not a universal machine-stack number or row result.
Compared with a 180 lb male who reaches a 72 lb Estimated 1RM, the ratio is 72 / 180 = 0.40, which reaches Advanced for men. The same 72 lb estimate at 240 lb bodyweight is 0.30x bodyweight, so the bodyweight-normalized score changes the interpretation.
A 140 lb female reaching 34 lb has a 0.24 ratio, which reaches Advanced for women when the same machine setup and range are preserved. A larger number produced by chest-pad bounce, row mechanics, or a shortened rearward finish is not a better standards result.
Execution gives the score its meaning. The arms begin forward, move out and back through shoulder horizontal abduction, reach a controlled rearward finish, and return under control; rows, shrugs, cable reverse flyes, face pulls, dumbbell reverse flyes, and per-arm resistance entries do not count.
Read the badge as strict guided rear-delt fly strength under one repeatable standard, not as proof that every rear-delt machine or neighboring pull would rank the same way.
Machine Reverse Fly Strength Standards
Machine Reverse Fly strength standards convert your Estimated 1RM-to-bodyweight ratio into Beginner, Novice, Intermediate, Advanced, Elite, and Stretch targets. Use the table for your sex, choose the nearest bodyweight row, then compare the calculated Estimated 1RM with the target columns.
These tables assume a dedicated seated reverse-fly, rear-delt fly, or reverse-pec-deck-style machine with the same seat height, chest-pad or torso-support setup, arm-start setting, handle or forearm-pad setup, range, tempo, and bilateral machine resistance convention. Table targets stop being valid when the tested range, setup, resistance convention, or movement identity changes.

For men, Beginner is below 0.16x, Novice begins at 0.16x, Intermediate begins at 0.26x, Advanced begins at 0.40x, Elite begins at 0.56x, and the stretch benchmark is 0.68x bodyweight. For women, Beginner is below 0.08x, Novice begins at 0.08x, Intermediate begins at 0.14x, Advanced begins at 0.24x, Elite begins at 0.34x, and the stretch benchmark is 0.43x bodyweight.
At 180 lb bodyweight, a male lifter needs about 72 lb for Advanced and 101 lb for Elite. At 140 lb bodyweight, a female lifter needs about 34 lb for Advanced and 48 lb for Elite.
Boundary values are lower-inclusive. A male result exactly at 0.40x counts as Advanced, and a female result exactly at 0.34x counts as Elite.
How the Machine Reverse Fly Calculator Works
The Machine Reverse Fly calculator estimates 1RM from the entered machine resistance and reps, divides that estimate by bodyweight, then compares the ratio with sex-specific standards. Ratio = Estimated 1RM / bodyweight.
If a 180 lb male records a 72 lb single, the ratio is 72 / 180 = 0.40, which is Advanced because the Advanced boundary is lower-inclusive. If he records 101 lb, the ratio is about 0.56, which reaches Elite.
If a 140 lb female records 48 lb, the ratio is about 0.34, which reaches Elite for women when the same machine setup and range are used.
The calculation applies to strict bilateral seated machine rear-delt isolation. Do not enter dumbbell reverse fly, cable reverse fly, face pull, machine seated row, machine chest fly, shrugs, high pulls, unilateral variations, partial-range work, assisted reps, or resistance values borrowed from a different machine family.
The result can rank a tested set against bodyweight-based standards, but it cannot prove transfer to every rear-delt machine because geometry, support, range, and resistance curve change the test.
Elite Machine Reverse Fly Strength Levels
Elite Machine Reverse Fly strength starts at 0.56x bodyweight for men and 0.34x bodyweight for women. Stretch benchmarks sit higher at 0.68x for men and 0.43x for women.
Perform a 101 lb Estimated 1RM at 180 lb bodyweight and the male ratio is about 0.56, which reaches Elite. Perform 48 lb at 140 lb bodyweight and the female ratio is about 0.34, which reaches Elite or better.
Elite proves that posterior-shoulder force through a controlled guided fly path remains strong under the tested setup. It does not count when the score is inflated by row mechanics, shrugging, cable substitutions, shorter range, assistance, or a machine setting that changes the movement.
At high ratios, failures usually appear as rearward range loss, chest-pad bounce, shoulder shrugging, row-like elbow drive, or uncontrolled return. A cleaner 101 lb result is more meaningful than a heavier number that breaks the standard.
Machine Reverse Fly Strength Compared to Other Lifts
Machine Reverse Fly comparisons are useful for weakness detection, not for copying one standards result into another calculator. Each neighboring lift changes support, path, muscle contribution, resistance convention, or range.
| Related Movement | Comparison Purpose | Key Constraint Difference | What The Gap Reveals |
|---|---|---|---|
| Dumbbell Reverse Fly | compare the closest free-weight reverse-fly anchor | dumbbells use per-hand free-weight load and more stabilization, while the machine guides the path | A large machine advantage may show that support and guidance help more than raw free-weight rear-delt control. |
| Machine Chest Fly | separate opposite-direction machine fly strength | chest flyes move forward for chest adduction; reverse flyes move backward for posterior-shoulder horizontal abduction | A stronger chest fly result does not mean stronger rear-delt isolation. |
| Machine Seated Row | show the row ceiling without treating it as reverse-fly strength | rows use elbow drive and stronger lat contribution; reverse flyes limit elbow flexion | A much stronger row score is normal and should not be entered as reverse-fly load. |
| Chest Supported Dumbbell Row | contrast supported rowing with supported rear-delt isolation | the row finishes toward the torso, while the reverse fly finishes in a wide rearward arc | The gap can show whether upper-back pulling strength transfers to rear-delt isolation control. |
| Dumbbell Lateral Raise | compare nearby shoulder-isolation control | lateral raises abduct the shoulder to the side; reverse flyes horizontally abduct the shoulder backward | A weak reverse fly beside a stronger lateral raise can point to posterior-deltoid or scapular-control limits. |
| Dumbbell Shrugs | separate trap loading from rear-delt fly strength | shrugs use shoulder elevation and much heavier trap loading; reverse flyes reject shrugging | A strong shrug result does not validate a reverse-fly score if the handles move by upper-trap takeover. |
If a 180 lb male reaches 101 lb on the machine reverse fly but ranks much lower on the closest free-weight comparison, the gap may show that machine support is helping more than free-weight control. If related rows are strong but machine reverse fly stalls, the likely limiter is posterior-deltoid isolation, scapular control, or the rearward finish.
Use comparison gaps as clues about guided rear-delt fly control, not as permission to replace one tested standard with another.
Milestones in Machine Reverse Fly Strength
Machine Reverse Fly milestones show when the bodyweight-ratio score moves from basic standards toward Advanced, Elite, and Stretch-level performance. Every milestone assumes the same machine setup and strict execution.
| Men’s Milestone | Ratio | 180 lb Target | Decision Rule |
|---|---|---|---|
| Intermediate | 0.26x bodyweight | 47 lb Estimated 1RM | Build repeatable range before chasing Advanced. |
| Advanced | 0.40x bodyweight | 72 lb Estimated 1RM | Retest only when the same setup is preserved. |
| Elite | 0.56x bodyweight | 101 lb Estimated 1RM+ | Reject any score raised by row mechanics or rebound. |
| Stretch Benchmark | 0.68x bodyweight | 122 lb Estimated 1RM | Use as a long-range benchmark, not a shortcut target. |
| Women’s Milestone | Ratio | 140 lb Target | Decision Rule |
|---|---|---|---|
| Intermediate | 0.14x bodyweight | 20 lb Estimated 1RM | Build repeatable range before chasing Advanced. |
| Advanced | 0.24x bodyweight | 34 lb Estimated 1RM | Retest only when the same setup is preserved. |
| Elite | 0.34x bodyweight | 48 lb Estimated 1RM+ | Reject any score raised by row mechanics or rebound. |
| Stretch Benchmark | 0.43x bodyweight | 60 lb Estimated 1RM | Use as a long-range benchmark, not a shortcut target. |
Someone at 180 lb with a 90 lb valid result is about 11 lb short of the Elite target. A 140 lb female at 28 lb is about 6 lb short of the Advanced target.
Choose the next target by the smallest honest gap: add resistance when range and finish are clean, improve setup consistency when the same score wobbles, and retest only when the same standard can be repeated.
Milestone progress is rejected when a higher score comes from a different range, assistance, machine setting, unilateral substitution, or resistance convention.
Related Strength Standards Tools
Related strength standards tools place Machine Reverse Fly inside a broader movement ecosystem. The goal is to compare what the current score may reveal, not to treat nearby tools as substitutions.
- Dumbbell Reverse Fly compares the closest free-weight rear-delt fly standard, useful for seeing whether machine guidance is doing more work than raw dumbbell control.
- Machine Chest Fly separates opposite-direction machine fly strength so posterior-shoulder results are not confused with chest adduction.
- Machine Seated Row shows the stronger machine pulling context while keeping row-style elbow drive out of the reverse-fly standard.
- Chest Supported Dumbbell Row contrasts supported rowing with supported rear-delt isolation and helps identify whether upper-back pulling strength transfers to strict fly control.
- Dumbbell Lateral Raise compares another strict shoulder-isolation pattern with different arm path and deltoid emphasis.
- Dumbbell Shrugs blocks upper-trap loading confusion and shows why shrug-dominant numbers should not be entered as reverse-fly strength.
Use the list in order when diagnosing a gap. A stronger related score with a weaker machine reverse fly result usually points toward the specific rear-delt isolation demand; a stronger machine reverse fly result with weaker free-weight comparisons may show that support or guidance is carrying part of the performance.
