Tools: one_rep_max rpe_estimate_max rpe_target_load plate_loading warmup_sets powerlifting_score check_program_file
one_rep_max | Estimate a one-rep max (1RM) from a set of weight × reps, with a percentage table and the load each rep count should allow. Epley by default, Brzycki optional. Estimates above 10 reps are flagged as less reliable. params: weight*, reps*, unit, formula |
rpe_estimate_max | Estimate a one-rep max from weight, reps and RPE, treating RPE as reps in reserve (RPE 8 = 2 reps left) and applying the one-rep max formula to reps + reps in reserve. params: weight*, reps*, rpe*, unit, formula |
rpe_target_load | Find the load for a set of a given number of reps at a target RPE, from a known or estimated one-rep max. Rounded to the nearest 0.5. params: oneRepMax*, reps*, rpe*, unit, formula |
plate_loading | Work out which plates to put on each side of a barbell to reach a target weight, using standard gym plates or the plates you list. Reports the exact load and anything your plates can’t make. params: target*, unit, bar, collars, collarWeight, plates |
warmup_sets | Build a warm-up ramp to a working weight: plate-friendly jumps, reps falling from 10 to singles, with the plates for each set. The same ramp the IronLedger app suggests. params: workingWeight*, sets, unit, bar |
powerlifting_score | Score a powerlifting total (or a bench press) against bodyweight with DOTS, IPF GL points and the original Wilks, using the coefficients the OpenPowerlifting rankings use. params: total*, bodyweight*, unit, sex*, equipment, event |
check_program_file | Check a training program written as a CSV or TSV file exactly as the IronLedger app will import it, before anyone loads it on a phone. Returns the weeks, sessions and exercises it creates, every skipped row and warning with its row number, the exercise names the app will question ("Did you mean ...?"), and names that will become new custom exercises. Use it whenever you write a program for someone params: file*, fileName |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
