Tools 9 found in our last check

• 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.

• 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.

• 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.

• 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.

• 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.

• 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 ge…

• 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 questio…
