Tools — strength calculators
All run in your browser; nothing is sent anywhere.
Barbell plate calculator
Enter a target weight and bar weight (kg or lb) and see exactly which plates to load on each side.
One-rep max
Estimate your 1RM from a working set using the Epley and Brzycki formulas.
RPE calculator
Convert a set's RPE and reps into a percentage of 1RM and an estimated max.
Wilks calculator
Normalise a powerlifting total across bodyweights with the Wilks coefficient.
The TDEE calculator is linked here as the central data source for energy and macro targets — it lives at its own route so goals and nutrition can reference it.
Resources — the Muscle Groups library
Browse muscle groups by category — Chest, Back, Shoulders, Arms, Legs, Core — and drill into individual exercises, each with its emphasis, typical equipment, and a short coaching cue.
Tip
The calculators use standard, public-domain formulas — handy for programming on the fly or settling a debate at the rack.
