Warm-up set calculator
Give it the weight you are working up to and it builds the ramp: how many sets, what to load, and how many reps on each. Loads are rounded to plates you can actually put on the bar.
Every warm-up set can be tagged as a warm-up in Mekimeki, which keeps it out of your volume totals and out of your PR history.

Your ramp
Weight climbs, reps fall. By the last set you have felt something close to the working load without spending anything on it.
| Set | % of working | Load | Reps |
|---|---|---|---|
| W1 | 40% | 47.5 kg | 10 |
| W2 | 60% | 72.5 kg | 6 |
| W3 | 80% | 95 kg | 3 |
What a warm-up is actually for
Two things, and neither is burning calories. The first is tissue: raising muscle temperature makes tendons more compliant and reduces the stiffness that a cold first rep meets. The second, and the one lifters underrate, is calibration. Your nervous system needs a preview of the load to recruit correctly for it.
That second job is why the ramp ends close to the working weight rather than halfway to it. A jump from 60% straight to a heavy triple is a set where the first rep is a surprise, and surprise is where technique breaks.
Why reps drop as the weight climbs
Warm-up sets are not training. Every rep you do under the working weight costs fatigue you wanted to spend on the working set. Ten reps at 40% is cheap and does the tissue job. Ten reps at 85% is a working set wearing a disguise.
The ramp here spends its reps where they are cheap and its intensity where it is useful: high reps low down, one to three reps at the top.
How many sets you need
- Two: accessories, second and third exercises of a session, anything where the muscles are already warm.
- Three: the default for most working weights on a main lift.
- Four or five: the first heavy lift of the day, a max attempt, or a cold morning session. Heavier working weights need more rungs because the gap between an empty bar and the load is bigger.
Rest between warm-up sets
Short at the bottom, longer at the top. The first two sets need only as long as it takes to change the plates. The last one, at 80% or more, deserves a genuine minute or two, because arriving at your working set already breathing hard defeats the purpose of the ramp.
Questions people ask
Do warm-up sets count towards my training volume?
They should not. Volume figures are meant to track training stress, and a ramp set at 40% adds tonnage without adding stress. In Mekimeki, tagging a set as a warm-up excludes it from volume totals and from personal record detection automatically.
Should I warm up for every exercise in a session?
Fully, only for the first heavy lift. After that, one or two ramp sets are usually enough, and for a third or fourth exercise hitting muscles you have already trained, often none. The list above defaults to fewer sets for a reason.
What about stretching before lifting?
Long static holds before heavy work have been shown to reduce force output for a short period afterwards. Movement-based warm-ups and ramp sets do not have that cost. Save long holds for after the session or a separate slot.
Should I warm up with an empty bar?
On squats, bench and overhead press, usually yes: it is a free rehearsal of the groove. The calculator never prescribes less than the bar, so if your working weight is light, the first row is the bar itself.
