Tools of IronLedger strength calculators
	Description		Read-only	Idempotent	Open world
`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 to import into IronLedger, and fix anything it reports first. The app names the program after the file, so pass the file name you will give it.

`five_three_one`Jim Wendler’s 5/3/1: the training max from a one-rep max (or a recent set of weight × reps) and every set of a four-week cycle, warm-ups and the deload, rounded to loadable weights. Option one or two percentages, a 90% or lower training max, and the next cycle’s training max for a named lift. Percentages and rounding follow Wendler’s 2009 manual.

`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.	Estimate a one-rep max (1RM) from a set of weight × reps, with a percentage table and the load each rep count should allow.

`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.

`strength_standards`Squat, bench press, deadlift and total percentiles for raw competition powerlifters, by sex, IPF weight class, age group and drug-tested status, from OpenPowerlifting’s public-domain meet results. Give a lift to place it among them. These describe competitive lifters, not the general gym population.
