What this is
A built-in 1RM calculator with weighted calisthenics and barbell modes plus multi-formula comparison.
Tools workflow
1RM Calculator With Formula and RPE Context
Strength estimates are only useful if they translate into actionable training loads. untraind combines formula comparison, weighted calisthenics support, and an RPE table in one built-in tool.
Built-in tools mean you do not need separate ad-heavy utility apps that interrupt training and disrespect your focus.
What this unlocks
Faster load planning, clearer intensity targets, and direct working-weight guidance from one recent set.
Why and when to use it
Use it when you need practical load targets for top sets, backoff work, or RPE-driven strength sessions.
From one set to usable working weights
The tool estimates 1RM across three formulas, supports bodyweight-aware calisthenics math, and maps the result into an RPE table so you can pick next-set loads quickly.
Weighted calisthenics and barbell modes are both built in.
Switch modes depending on whether bodyweight is part of the lifted load, then compare total and added-weight outputs.
Three formulas are visible side by side.
Epley, Brzycki, and Lander estimates are shown together so you can choose a conservative or aggressive target intentionally.
RPE table is generated from your estimate.
Use the built-in table to pick practical working weights by rep target and effort level without manual spreadsheets.
1RM calculator FAQ
Does this support weighted pull-ups and dips?
Yes. Weighted calisthenics mode includes bodyweight in the total load and shows the added external load separately.
Why show multiple formulas instead of one number?
Different formulas behave differently across rep ranges. Seeing all three helps you choose a target with context.
Can I turn the estimate into next-set weights quickly?
Yes. The built-in RPE table converts your estimate into actionable working weights for common rep targets.
