Why ramp up properly

Better top sets

Gradual loading lets you practise the groove and feel ready for heavy weight.

Lower injury risk

Muscles and joints warm through the full range before taking real load.

No wasted energy

Tapering reps keep fatigue low so your working sets do not suffer.

How to plan your warm-up

  1. Enter your top setType the working weight and reps, then choose units and bar.
  2. Pick the number of setsChoose 3 to 6 warm-ups, and whether to start with the empty bar.
  3. Follow the tableLoad the listed plates, do the reps and rest as shown, then hit your working sets.

A typical barbell warm-up

Most coaches ramp from about 40% of the working weight up to around 90%, with reps falling from 5 to 8 down to a single. The empty bar first gets blood flowing and checks technique.

Rounding matters: loads are rounded to your smallest jump (for example 2.5 kg or 5 lb) so every set can be built from standard plates.

40-60%

Movement practice with 5 to 8 easy reps.

70-80%

Two or three reps to feel heavier load.

85-90%

A single to prime for the working weight.

Warm-up set FAQ

Why do warm-up sets get fewer reps as the weight rises?

Warm-ups should prepare you without tiring you. High reps with light weight groove the movement; low reps near the top set prime the nervous system without fatigue.

How many warm-up sets do I need?

Heavier working sets need more steps. Three is usually enough for light work; five or six for a near-max single.

What is the low-fatigue option?

It trims reps on every warm-up, useful before heavy singles, doubles or high-volume days.

Why did some sets disappear?

When rounding puts two warm-ups at the same load, or a load at or below the bar, the duplicate is dropped.

Which plates does it use?

Standard plates: 25, 20, 15, 10, 5, 2.5 and 1.25 kg, or 45, 35, 25, 10, 5 and 2.5 lb.
