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.

Method: Warm-ups land on bar + 10, + 20, + 30 and so on, spread from about half the working weight (or bar + 50 for heavy lifts) to about 85% of it; reps 10, 5, then singles.

## Query parameters

- `workingWeight` number, required: The first working set’s weight.
- `sets` integer: Number of warm-up sets, 1 to 12.
- `unit` 'kg' | 'lb': Weight unit for every load in and out: kg or lb.
- `bar` number: Bar weight in the chosen unit. Defaults to 20 kg or 45 lb.
