Protocol tools
Training calculators that explain the work.
Free, indexable tools for lifters who run structured training. The calculators stay transparent: formulas, caveats, and practical use before hype.
Growth wedge
Start with useful calculators, earn links only after the tool deserves them, then expand into programs and comparisons.
Training tool
One-rep max calculator
Estimate your 1RM from a recent set, then turn that estimate into a practical training-max reference. Useful for structured lifting blocks. Not a promise of a tested max.
Open calculatorTraining tool
Training max calculator
Turn an estimated 1RM into a conservative training max. Useful when the program should be driven by repeatable work, not a once-in-a-while peak.
Open calculatorTraining tool
RPE load calculator
Estimate a load for a target rep and RPE prescription. The output is a planning reference, not proof that the set will feel exactly right.
Open calculatorTraining tool
Plate calculator
Turn a target weight into plates per side. Useful when the program gives the number and you want the bar loaded without doing gym-floor arithmetic.
Open calculatorTraining tool
Warm-up calculator
Plan ramp-up sets before a target work weight. The goal is not to make warming up complicated; it is to remove arithmetic before the set that matters.

These are planned because serious lifters already use them inside spreadsheets and training apps.

The publishing rule
A Protocol tool page needs to do real work before it asks for attention: working calculator, formula transparency, source links, conservative wording, internal links, analytics events, and a clear path into the app.
