Machine Chest Fly Strength Standards Calculator
Compare your Machine Chest 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 61 lb at 190 lb for a man and 26 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 chest 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 Chest 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 Chest Fly Strength Score
Your Machine Chest Fly strength score is Estimated 1RM divided by bodyweight, using only strict bilateral seated machine chest isolation performed under a repeatable machine setup. The score ranks strict guided chest-adduction strength, not a universal machine-stack number.
For a man at 180 lb bodyweight, Advanced begins at 92 lb estimated 1RM. At 240 lb bodyweight the Advanced entry is 111 lb. Machine settings and the accepted range must stay consistent when comparing results.
For a woman at 140 lb bodyweight, Advanced begins at 42 lb. A larger number from a shortened range or changed machine setting does not represent the same test.
Execution gives the score its meaning. the arms open to a repeatable chest stretch and move forward through shoulder horizontal adduction; chest pressing, excessive elbow extension, shortened range, handle slamming, machine-stop rebound, twisting, and per-arm resistance entry do not count.
Read the badge as strict guided chest-adduction strength under one repeatable standard, not as proof that every machine or neighboring lift would rank the same way.
Machine Chest Fly Strength Standards
Machine Chest 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 chest fly or pec-deck-style machine with the same seat height, back pad, 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.

|---|---|---|---|---|---|
| 100 lb | 12 lb | 20 lb | 34 lb | 49 lb+ | 60 lb+ |
| 110 lb | 13 lb | 21 lb | 36 lb | 52 lb+ | 63 lb+ |

| 220 lb | 21 lb | 34 lb | 57 lb | 83 lb+ | 101 lb+ |
These are bodyweight-specific comparison targets. For a 190 lb man the tier entries are Novice 39 lb, Intermediate 61 lb, Advanced 95 lb, Elite 134 lb. For a 150 lb woman they are Novice 16 lb, Intermediate 26 lb, Advanced 44 lb, Elite 64 lb. The stretch reference is 160 lb and 78 lb respectively; a result above it still belongs to Elite.
At 180 lb bodyweight, a man reaches Advanced at 92 lb and Elite at 129 lb. At 140 lb bodyweight, a woman reaches Advanced at 42 lb and Elite at 61 lb.
Each whole-pound table entry is the first weight that enters the named level in the calculator. The preceding whole pound is below that boundary; the ratio that marks a tier changes with bodyweight.
How the Machine Chest Fly Calculator Works
The Machine Chest 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.
For a man at 180 lb bodyweight, a valid 92 lb single enters Advanced, and a valid 129 lb single enters Elite. Keep the same machine, settings and full range for both tests.
For a woman at 140 lb bodyweight, a valid 61 lb single enters Elite. The weight only counts under the same machine setup and movement rules.
The calculation applies to strict bilateral seated machine chest isolation. Do not enter dumbbell fly, incline dumbbell fly, chest press machine, dumbbell bench press, Smith machine bench press, dumbbell reverse fly, 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 related lift or machine because geometry, support, and range change the test.
Elite Machine Chest Fly Strength Levels
Elite Machine Chest Fly strength is a bodyweight-adjusted benchmark. At 190 lb for men it starts at 134 lb, and at 150 lb for women at 64 lb. Stretch references at those bodyweights are 160 lb and 78 lb respectively.
For a man at 180 lb, Elite begins at 129 lb estimated 1RM; for a woman at 140 lb, it begins at 61 lb. The standards remain specific to this machine exercise.
Elite proves that pectoral force through a controlled fly path remains strong under the tested setup. It does not count when the score is inflated by dumbbell fly, incline dumbbell fly, chest press machine, shorter range, assistance, or a machine setting that changes the movement.
At heavier weights, check for range loss, setup drift, finish weakness or an uncontrolled return. A valid full-range result is more useful than a larger number that breaks the movement standard.
Machine Chest Fly Strength Compared to Other Lifts
Machine Chest 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 Fly | compare the closest free-weight chest fly anchor | free dumbbells require independent-arm stability and combined-dumbbell entry, while the machine guides the path | What The Gap Reveals: primary fly anchor can show whether the machine fly score reflects strict guided chest-adduction strength or a different strength quality. |
| Incline Dumbbell Fly | contrast strict incline free-weight fly strength with machine-guided chest adduction | incline dumbbell flyes add bench angle and free-weight bottom control that machine flyes reduce | What The Gap Reveals: strict fly contrast can show whether the machine fly score reflects strict guided chest-adduction strength or a different strength quality. |
| Chest Press Machine | show the machine pressing ceiling without treating it as a fly standard | chest press machines use elbow extension and pressing leverage; machine chest flyes stay in a non-pressing fly path | What The Gap Reveals: machine press contrast can show whether the machine fly score reflects strict guided chest-adduction strength or a different strength quality. |
| Dumbbell Bench Press | compare chest isolation with a stronger compound dumbbell press | dumbbell bench pressing uses triceps and elbow extension, while machine chest flyes isolate chest adduction | What The Gap Reveals: compound press anchor can show whether the machine fly score reflects strict guided chest-adduction strength or a different strength quality. |
| Smith Machine Bench Press | contrast guided-bar pressing with guided chest isolation | Smith pressing is guided but still a press; machine chest flyes remain a fly pattern | What The Gap Reveals: guided press contrast can show whether the machine fly score reflects strict guided chest-adduction strength or a different strength quality. |
| Dumbbell Reverse Fly | prevent fly-name confusion by comparing opposite-direction shoulder work | reverse flyes train posterior-shoulder horizontal abduction, not chest adduction | What The Gap Reveals: invalid-substitution boundary can show whether the machine fly score reflects strict guided chest-adduction strength or a different strength quality. |
Compare this machine result with the closest free-weight test using each exercise’s own tier. A stronger machine tier can guide a review of free-weight control, while a weaker machine tier can guide a review of machine path, range and finish; it does not prove the cause of the gap.
Use comparison gaps as clues about pectoral force through a controlled fly path, not as permission to replace one tested standard with another.
Milestones in Machine Chest Fly Strength
Machine Chest 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.
| Level | 180 lb man estimated 1RM |
|---|---|
| Novice | 38 lb |
| Intermediate | 59 lb |
| Advanced | 92 lb |
| Elite | 129 lb |
| Stretch | 154 lb |
| Level | 140 lb woman estimated 1RM |
|---|---|
| Novice | 15 lb |
| Intermediate | 25 lb |
| Advanced | 42 lb |
| Elite | 61 lb |
| Stretch | 74 lb |
For a man at 180 lb, a result 10 lb below the Elite entry means the next target is 129 lb. For a woman at 140 lb, a result 6 lb below Advanced means the next target is 42 lb. Both targets require the accepted range and setup.
Choose the next target by the smallest honest gap: add resistance when range and finish are clean, improve execution 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 Chest 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 Fly compare the closest free-weight chest fly anchor so the machine fly result is compared against same chest fly pattern with different support, with the main difference that free dumbbells require independent-arm stability and combined-dumbbell entry, while the machine guides the path.
- Incline Dumbbell Fly contrast strict incline free-weight fly strength with machine-guided chest adduction so the machine fly result is compared against same isolation family with different angle and control, with the main difference that incline dumbbell flyes add bench angle and free-weight bottom control that machine flyes reduce.
- Chest Press Machine show the machine pressing ceiling without treating it as a fly standard so the machine fly result is compared against same implement family with different movement pattern, with the main difference that chest press machines use elbow extension and pressing leverage; machine chest flyes stay in a non-pressing fly path.
- Dumbbell Bench Press compare chest isolation with a stronger compound dumbbell press so the machine fly result is compared against same primary muscles with stronger compound leverage, with the main difference that dumbbell bench pressing uses triceps and elbow extension, while machine chest flyes isolate chest adduction.
- Smith Machine Bench Press contrast guided-bar pressing with guided chest isolation so the machine fly result is compared against guided implement with different leverage, with the main difference that Smith pressing is guided but still a press; machine chest flyes remain a fly pattern.
- Dumbbell Reverse Fly prevent fly-name confusion by comparing opposite-direction shoulder work so the machine fly result is compared against fly name overlap with opposite target, with the main difference that reverse flyes train posterior-shoulder horizontal abduction, not chest adduction.
Use the list in order when diagnosing a gap. A stronger related score with a weaker machine fly result usually points toward the specific machine path, range, or isolation demand; a stronger machine fly result with weaker related lifts may show that support or guidance is carrying part of the performance.
