One-Rep Max Formula Comparison
Compare two named repetition-based strength estimates without disguising their disagreement. The calculator keeps Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps) visible so the selected inputs and resulting epley estimate can be checked together.

What one-rep max formula comparison calculates
Compare two named repetition-based strength estimates without disguising their disagreement.
The scope of epley estimate stops at Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps), so an unstated population or decision threshold is not inferred.
How each field enters epley estimate
- Lifted weight: For one-rep max formula comparison, the worked lifted weight is 80 kg. Preserve kg and its measurement source because this field supplies a distinct term in comparison of Epley and Brzycki equations. Under comparison of Epley and Brzycki equations, the accepted range for lifted weight runs from 0.1 through 1000.
- Completed repetitions: The one-rep max formula comparison field for completed repetitions carries 6 reps. Keep its time point and definition beside the result produced by Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps). Under comparison of Epley and Brzycki equations, the accepted range for completed repetitions runs from 1 through 12.
A coherent one-rep max formula comparison setup requires aligned dates, definitions, and measurement sources across lifted weight, completed repetitions.
Applying comparison of Epley and Brzycki equations to one-rep max formula comparison
Under comparison of Epley and Brzycki equations, the result panel reports epley estimate, brzycki estimate, difference between formulas. Match each symbol or operation in Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps) to the labeled lifted weight, completed repetitions fields before substituting numbers.
Inspect every denominator in the one-rep max formula comparison equation Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps). Under comparison of Epley and Brzycki equations, a zero or near-zero denominator can make the result undefined, unstable, or misleadingly large.
Reproducing the example for one-rep max formula comparison
The displayed case begins with Lifted weight = 80 kg, Completed repetitions = 6 reps.
Using those defaults, the calculator reports Epley estimate = 96.0 kg; Brzycki estimate = 92.9 kg; Difference between formulas = 3.1 kg. This fixed one-rep max formula comparison case checks Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps) after code, browser, or formatting changes.
Test epley estimate by changing a single one-rep max formula comparison assumption before altering the rest of the setup.
Prediction is exercise-specific
For one-rep max formula comparison, use a technically sound set close enough to fatigue to be informative without forcing an unsafe attempt. For one-rep max formula comparison, assistance or shortened range changes the meaning of the repetitions.
For one-rep max formula comparison, epley and Brzycki diverge as repetitions increase, so retain the named equation with any saved estimate.
A related measurement may be easier to interpret beside training volume and rest time.
Where one-rep max formula comparison needs context
For one-rep max formula comparison under comparison of Epley and Brzycki equations, movement results depend on the stated distance, duration, workload, and body measurements; terrain, technique, equipment, and environmental conditions remain outside simple arithmetic.
Reversing the ratio in Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps) answers a different one-rep max formula comparison question, so retain its numerator and denominator labels.
Quality checks before saving one-rep max formula comparison
Check lifted weight, completed repetitions against their labels in Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps). A transposed value can remain numerically valid while describing a different comparison of Epley and Brzycki equations setup.
For one-rep max formula comparison under comparison of Epley and Brzycki equations, do not substitute zero for missing data, reuse a rounded intermediate as the original measurement, or combine time boundaries.
Rebuilding one-rep max formula comparison later
When recording one-rep max formula comparison from comparison of Epley and Brzycki equations, compare movement sessions only after confirming that the timing method, route, recovery interval, and intensity definition were recorded consistently.
Store lifted weight, completed repetitions, their units and dates, the equation Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps), and the unrounded epley estimate, brzycki estimate, difference between formulas values. Note one-rep max formula comparison exclusions or selected rates explicitly so another reader can reconstruct the comparison of Epley and Brzycki equations result.
Questions about one-rep max formula comparison
What does epley estimate represent here?
It is the output of Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps) using the displayed lifted weight, completed repetitions. Under comparison of Epley and Brzycki equations, it represents the limited one-rep max formula comparison question named above, not an unstated diagnosis or treatment decision.
When does one-rep max formula comparison need additional interpretation?
Use additional context whenever the comparison of Epley and Brzycki equations result affects care, pregnancy, a child, urgent symptoms, medication, or safety. The page checks Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps), not whether a personal one-rep max formula comparison decision is suitable.
Can a missing one-rep max formula comparison input be entered as zero?
Under comparison of Epley and Brzycki equations, enter zero only when it was observed and permitted by the field definition. For one-rep max formula comparison, missing information and measured zero have different roles in Epley = weight x (1 + reps/30); Brzycki = weight x 36/(37 - reps).
