If you know your lift but not your level
Start with a lift-specific calculator or the full strength standards page. Those pages convert a raw number into bodyweight-adjusted context.
Site Directory
All Calculators, Standards, and Guides
The site is organized by user intent: estimate a max, compare a lift, diagnose a strength profile, prepare for a meet, analyze a correlation, or verify the methodology behind a result.

Meet prep
If you compete or plan to compete
Use the powerlifting section for total scoring, attempt selection, Wilks, DOTS, warm-ups, and competition readiness.
Statistics
If your data question is not about lifting
The statistics section groups Pearson correlation, p-values, R-squared, Spearman, partial correlation, and causation guides.

Lifts
Lift-specific strength calculators
Use these pages when the question is about one movement rather than your whole strength profile.
Compare one lift, find weak points, and choose the next lift-specific target.

Bench Press Calculator
Benchmark your bench press strength level, percentile, and training loads.
Squat Calculator
Project squat maxes, rep tables, and progression targets by bodyweight.
Deadlift Calculator
See your deadlift max, intensity zones, and level progression instantly.
Overhead Press Calculator
Estimate OHP 1RM, compare strict-press standards, and check your push balance ratio.
Pull-Up Calculator
Compare bodyweight reps, weighted pull-ups, and assisted pull-up progress with bodyweight factored in.
Barbell Row Calculator
Estimate bent-over row 1RM and check whether your back strength balances your bench press.
Standards
Standards and milestone pages
Use these pages when you want context: your level, your bodyweight ratio, and the next milestone worth chasing.
Turn isolated lift numbers into a full strength profile and milestone roadmap.
Powerlifting
Powerlifting and meet prep
Competition-focused pages for totals, attempts, Wilks, DOTS, and platform planning.
Prepare attempts, interpret a total, and compare relative strength across bodyweights.
CompetitionOpen pageCompetitionOpen pageRelative StrengthOpen pageRelative StrengthOpen pageLegacyOpen page
Powerlifting Total Calculator
Calculate total, IPF GL, DOTS, Wilks, percentile, and lift balance from squat, bench, and deadlift.
Powerlifting Attempt Calculator
Pick openers, seconds, thirds, warm-ups, and contingencies for meet day.
Wilks Calculator
Estimate Wilks-style relative strength points from bodyweight and total.
DOTS Calculator
Compare powerlifting totals across bodyweights with DOTS scoring.
Classic Powerlifting Total Page
Older powerlifting total and meet-planning page kept for visitors and internal references that still use the classic route.
Statistics
Statistics and correlation guides
Correlation pages for r, p-values, R-squared, Spearman, partial correlation, and causal interpretation.
Calculate correlation outputs and understand whether the result is strong, significant, or causal.

Pearson Correlation
Compute correlation significance from Pearson r and sample size.
R-Squared Guide
See how much of a correlation is actually explained with an interactive R² visualizer.
Correlation P-Value
Test whether a Pearson correlation is statistically significant from r and sample size.
How to Interpret Correlation
A practical guide to reading positive, negative, weak, moderate, and strong correlation coefficients.
Pearson vs Spearman Correlation
Choose the right correlation method based on linearity, monotonic relationships, outliers, and ordinal data.
Spearman Correlation
Use rank correlation when the relationship is monotonic, non-normal, ordinal, or sensitive to outliers.
Partial Correlation
Measure the relationship between two variables after controlling for a third variable.
Correlation vs Causation
Understand why a statistically meaningful relationship still does not prove cause and effect.

Why the navigation is grouped this way
Calculator sites become hard to use when every page is treated as the same kind of link. A lifter looking for a bench press benchmark, a meet-day attempt plan, and a Pearson correlation p-value has three different search intents. The navigation now reflects those intents instead of forcing every route into one flat menu.
This directory also gives search engines a clean crawl path to every major page: calculators, standards, powerlifting resources, statistics explainers, blog articles, methodology, and policies are all linked from one categorized hub with descriptive anchor text.
