Powerlifting attempts

Tool id: powerlifting-attempts · Methods: standard

Turn an estimated 1RM into a meet-day attempt plan; reach for it to pick openers and a warm-up ramp.

Input

Field	Type	Notes
one_rep_max	{ value, unit }	kg or lb — your estimated max
bar_weight	{ value, unit } | null	defaults to 20 kg / 45 lb
available_plates	number[] | null	per-side plate sizes in the same unit — defaults to standard plate sets
aggressiveness	"conservative" | "standard" | "aggressive"	controls attempt percentages; defaults to "standard"

Attempt percentages by aggressiveness:

	Opener	Second	Third
conservative	88%	93%	98%
standard	90%	95%	101%
aggressive	91%	97%	103%

Methods

• standard — Deterministic opener/second/third attempts derived from the estimated 1RM at the percentages above, then snapped to the nearest loadable weight given the bar and available plates. Also produces a warm-up ramp from bar-only up to the opener weight, with per-side plate loading for every set.

Example

TypeScript

import { REGISTRY } from "@almostjacked/fitness-tools";
const pl = REGISTRY.get("powerlifting-attempts")!;
pl.compute(pl.input.parse({
  one_rep_max: { value: 200, unit: "kg" },
}));
