What Your Single Leg Machine Leg Press Result Means for Pendulum Squat
This calculator turns one strict Single Leg Machine Leg Press result into a predicted Pendulum Squat 1RM. The result gives you a center estimate, a planning range, and a strength level for the Pendulum Squat only.
| Example | Single Leg Machine Leg Press result | Estimated Single Leg Machine Leg Press max | Predicted Pendulum Squat | Expected range | Target level |
|---|---|---|---|---|---|
| 190 lb male | 160 lb displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup × 8 | 199 lb | 336 lb | 311–340 lb | Novice |
| 150 lb female | 100 lb displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup × 8 | 124 lb | 221 lb | 196–239 lb | Novice |
For the male example, 160 lb displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup × 8 predicts 336 lb with a 311–340 lb range. The Novice label rates the predicted Pendulum Squat result; it does not rate the Single Leg Machine Leg Press result.
How the Single Leg Machine Leg Press to Pendulum Squat Conversion Works
The calculator keeps the source and target measurement rules separate: the source entry is displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup, while the target result is total external weight.
| Step | What the calculator does | Worked example |
|---|---|---|
| 1. Read the source load | Use displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup exactly as entered. | 160 lb displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup × 8 |
| 2. Estimate the source max | Convert the completed set into an estimated source 1RM using the calculator’s approved repetition rule. | 199 lb |
| 3. Map to the target result | Apply the Single Leg Machine Leg Press-to-Pendulum Squat mapping (0.592 center coefficient for this male example). | 336 lb |
| 4. Show uncertainty | Calculate the lower and upper ends of the expected transfer range. | 311–340 lb |
| 5. Rate the target | Classify the unrounded center against Pendulum Squat 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 Pendulum Squat performance to learn your actual result.
Pendulum Squat Strength Standards
The calculator rates only the predicted Pendulum Squat result. These reference standards use the same bodyweights and sex profiles as the examples above.
| Pendulum Squat level | 190 lb male: total external weight | 150 lb female: total external weight |
|---|---|---|
| Beginner | Below 228 lb | Below 150 lb |
| Novice | 228–341 lb | 150–224 lb |
| Intermediate | 342–474 lb | 225–314 lb |
| Advanced | 475–607 lb | 315–404 lb |
| Elite | 608 lb or more | 405 lb or more |
| Stretch benchmark | 684 lb | 450 lb |
The live calculator resolves the target standard for the bodyweight entered. The source exercise keeps its own separate standards.
Key Differences Between Single Leg Machine Leg Press and Pendulum Squat
These exercises share relevant strength demands, but the differences below are why their raw numbers cannot be interchanged.
| Difference | Single Leg Machine Leg Press | Pendulum Squat | Why it affects the estimate |
|---|---|---|---|
| Movement and setup | Single Leg Machine Leg Press: strict Single Leg Machine Leg Press. | Pendulum Squat: strict pendulum squat. | The starting position and movement path determine the leverage and muscles that can contribute to a valid repetition. |
| Equipment and recorded resistance | The displayed, selected, or weighted machine resistance used for strict one-leg leg press reps on the same machine setup using leg press machine. | Total weighted or selected machine resistance according to the machine label, not bodyweight or per-side plate load. | The equipment and the way resistance is recorded make the displayed numbers unsuitable for direct substitution. |
| Primary performance demands | the stated exercise setup and action, repeatable full-range execution, stable positioning | guided quadriceps and glute squat force, controlled deep knee and hip flexion, stable back support and foot position | A different mix of force, stability, mobility, and repetition endurance can move actual target performance away from the estimate. |
| Valid repetition standard | Each rep begins on a dedicated leg press machine with one working foot planted on the platform. The working leg descends to a consistent strict depth allowed by the machine, hip comfort, and knee comfort. | Each rep begins with the lifter secured in the pendulum squat machine, feet set, safeties clear, and load controlled. Descend to the defined depth on the machine path, then drive back to full supported standing extension. | A set only belongs in the conversion when it follows the source test, and the prediction only represents the stated target test. |
Getting and Using a Useful Single Leg Machine Leg Press-to-Pendulum Squat Estimate
Source test: Each rep begins on a dedicated leg press machine with one working foot planted on the platform. The working leg descends to a consistent strict depth allowed by the machine, hip comfort, and knee comfort. A valid finish requires controlled extension without aggressive knee hyperextension, hip lift, sled slam, or loss of foot position.
Target represented: Each rep begins with the lifter secured in the pendulum squat machine, feet set, safeties clear, and load controlled. Descend to the defined depth on the machine path, then drive back to full supported standing extension. A valid finish requires controlled top position without bouncing safeties, shortening depth, or changing foot position.
| Before calculating | What to do |
|---|---|
| Use a valid Single Leg Machine Leg Press set | Each rep begins on a dedicated leg press machine with one working foot planted on the platform. The working leg descends to a consistent strict depth allowed by the machine, hip comfort, and knee comfort. |
| Use 1 to 10 strict repetitions | Enter one whole-number Single Leg Machine Leg Press set inside the calculator’s approved repetition range. |
| Keep the measurement convention straight | Enter displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup. Read the target as total external weight. |
| Use the range for planning | Start Pendulum Squat practice near the conservative end and use the center as the main comparison point. |
| Retest under the same conditions | Keep the Single Leg Machine Leg Press setup, range, way of recording resistance, and repetition standard consistent. |
Do not substitute Pendulum Squat results entered as Single Leg Machine Leg Press results, Single Leg Machine Leg Press repetitions performed with a changed setup or range, partial-range, assisted, or momentum-driven Single Leg Machine Leg Press repetitions, source resistance recorded under a different convention than displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup, 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 Single Leg Machine Leg Press-to-Pendulum Squat estimate. |
| Low end of range | Use it as the conservative reference when beginning or resuming Pendulum Squat practice. |
| High end of range | Treat it as possible context—not a guaranteed result or attempt recommendation. |
| Pendulum Squat strength level | Use it only to understand where the predicted result falls against Pendulum Squat standards. |
| Direct Pendulum Squat result | Replace the prediction with the actual result once Pendulum Squat has been performed under the stated test. |
Example: 160 lb displayed, selected, or loaded machine resistance used for strict one-leg leg press reps on the same machine setup × 8 predicts 336 lb with a 311–340 lb range. Use 336 lb as the comparison point, treat 311 lb as the conservative edge, and do not interpret 340 lb as a recommended attempt. Once you record a strict Pendulum Squat result, use that direct result instead.
