Warm-Up Sets Calculator

Enter your first working set and get the full ramp to it — sets, reps, percentages and rest, starting from the empty bar.

Your first working set

  1. 1

    20 kg × 8

    Empty bar · rest 30–45 s

  2. 2

    47.5 kg × 5

    40% of working weight · rest 30–45 s

  3. 3

    65 kg × 4

    55% of working weight · rest 60 s

  4. 4

    85 kg × 3

    70% of working weight · rest 60 s

  5. 5

    102.5 kg × 2

    85% of working weight · rest 90–120 s

  6. 6

    110 kg × 1

    Primer · rest 90–120 s

  7. ★

    120 kg — first working set

    Rest 2–5 min before this one, depending on how heavy it is for you.

What a warm-up is actually for

A ramp does three things, and none of them is "getting warm" in the literal sense. It raises muscle temperature, which improves force production and tissue compliance. It rehearses the movement pattern under progressively heavier load, so by the time the working weight is on the bar your groove is already found. And it primes the nervous system — a heavy single at 90% makes the subsequent working set feel lighter, an effect called post-activation potentiation.

What it must not do is tire you out. Every warm-up rep is a rep you don't get to do at your working weight. The whole design problem is getting all three benefits in the fewest sets possible.

The shape of a good ramp

Weight goes up, reps come down, and the gaps between the sets shrink in percentage terms as you approach the top. The ramp above follows that pattern:

  • Empty bar × 8 — pattern rehearsal, no load to speak of.
  • 40% × 5 — the first real weight, still trivially easy.
  • 55% × 4 and 70% × 3 — the working part of the ramp, where temperature actually rises.
  • 85% × 2 — heavy enough that the working weight will feel familiar.
  • 92% × 1 — the primer. One rep, well short of a grind.

Steps that round onto each other are dropped automatically, so a lighter working weight produces a shorter ramp — there's no value in doing 42.5 kg and then 45 kg.

Before the bar

None of the above replaces general preparation. Five to ten minutes of easy cardio to raise core temperature, and some movement-specific mobility for whatever your limiting joint is, belong before the first set. What they don't need to be is long, or static: prolonged static stretching immediately before heavy lifting measurably reduces force output for the next half hour or so.

Common mistakes

  • Too many sets. Eight warm-up sets before a top set of five is a workout in itself. Four or five is plenty.
  • Too many reps at the top. A set of 5 at 85% isn't a warm-up, it's a working set. Reps must fall as weight rises.
  • Skipping the empty bar. Starting at 50% skips the cheapest, most useful part of the ramp — free pattern practice with zero fatigue cost.
  • Full rest throughout. Resting three minutes after 40% wastes the session and lets you cool back down.

If you're not sure what your working weight should be,check your rep max chart, thenwork out the plates for each step of the ramp. Arest timer keeps the short gaps honest.

Frequently asked questions

How many warm-up sets should I do?

+

Three to five for a heavy compound, fewer as the working weight comes down. The test is simple: your first working set should feel like the first hard thing you've done, not the first thing you've done. If you arrive at it already tired, the ramp was too long.

Should warm-up sets be taken to failure?

+

Never. Warm-up reps are there to rehearse the movement and prime the nervous system, not to accumulate fatigue. Every set in this ramp stops well short — the top single at 92% is a primer, not an attempt.

How long should I rest between warm-up sets?

+

Very little at the bottom — 30 to 45 seconds — and more as the weight climbs, up to two minutes before the last primer. The point is to arrive at your working set recovered, and the heavy warm-ups are the only ones that actually cost you anything.

Do I need to warm up for every exercise?

+

Fully, only for the first heavy compound of the session. After that you're already warm, and accessories usually need one light set to find the groove rather than a full ramp.

Does the ramp change for deadlifts?

+

The percentages hold, but many lifters cut the total number of sets because deadlifts are more fatiguing per rep. If you're pulling heavy, consider dropping one of the middle steps rather than the top primer.
