What a warm up set calculator does
A warm up set calculator turns one number, your work weight, into a ramp of lighter sets. You start with the empty bar. Each set adds weight until you reach the load you came to lift. The tool does the percent math, rounds every set to a weight your plates can make, and shows the plates for each side of the bar.
Doing this in your head is slow between sets. Is 60 percent of 275 lb a 165 or a 170? Which plates make it? This page answers as you type, so you can plan the whole ramp before you chalk up.
How to use the calculator
- Pick pounds or kilograms.
- Type your work weight, with the bar included. Or tap a common weight.
- Pick a warm up style: powerlifting, strength or hypertrophy. Choose Custom to type your own percents.
- Choose your bar. A standard men's bar is 45 lb or 20 kg. Many women's bars are 35 lb or 15 kg.
- Turn off any plate your gym does not have. Then pick how finely to round each set.
- Read the table, tap Copy as text, or tap Print to take the sheet to the gym.
How each set is worked out
Each warm up weight is your work weight times a percent, divided by 100. The tool rounds that number to your chosen step, 5 lb or 2.5 kg by default. Then it finds the closest load your plates can build. Plates per side are the total, minus the bar, divided by 2.
The result never repeats a weight, and it never goes above your work set. If a set would land on the bar, on the set before it, or too close to either, the tool drops it. If your plates cannot make your exact work weight, the tool says so and uses the closest load. It then takes the percents from that load. The table shows the percent you asked for, and the real percent when rounding moves it. Kilogram and pound entries convert with one pound equal to exactly 0.45359237 kg, the value set by the 1959 international yard and pound agreement.
The three warm up styles
No standard warm up exists. Coaches differ, and the best ramp depends on your lift, your fatigue and your goal. The Strength style follows the warm-up template of the Starting Strength program by Mark Rippetoe: the empty bar for 2 sets of 5, then about 40, 60 and 80 percent of the work weight. The Powerlifting and Hypertrophy styles are common starting points. They have no single source, and we do not claim one. Change them if they do not suit you.
| Style | Sets after the bar | Best for |
|---|---|---|
| Powerlifting | 30, 50, 65, 75, 85, 90% | Heavy triples and singles |
| Strength | 40, 60, 80% | Sets of 5, linear progression |
| Hypertrophy | 50, 75% | Sets of 8 to 12 |
Sets that sit too close together are dropped. Powerlifting needs a 20 lb (10 kg) jump. The other styles need 10 lb (5 kg). At light weights that gives a shorter ramp, so a 135 lb lifter does not warm up with six sets.
Reps drop as the weight rises. The aim is to feel the movement without tiring yourself for the work set.
Worked example: a 225 lb work set
Take a 225 lb top set on a 45 lb bar, with the strength style and standard plates. The ramp is:
- 90 lb (40%): 10 lb × 2 + 2.5 lb per side.
- 135 lb (60%): 45 lb per side.
- 180 lb (80%): 45 lb + 10 lb × 2 + 2.5 lb per side.
- 225 lb (work set): 45 lb × 2 per side.
Before those, you lift the empty 45 lb bar for two sets of 5.
Common work weights and their ramps
These ramps use the strength style, a 45 lb bar and plates down to 2.5 lb. Weights are the total on the bar, starting with the empty bar.
| Work set | Ramp in pounds |
|---|---|
| 135 lb | 45, 55, 80, 110, 135 |
| 185 lb | 45, 75, 110, 150, 185 |
| 225 lb | 45, 90, 135, 180, 225 |
| 275 lb | 45, 110, 165, 220, 275 |
| 315 lb | 45, 125, 190, 250, 315 |
| 365 lb | 45, 145, 220, 290, 365 |
| 405 lb | 45, 160, 245, 325, 405 |
How many warm up sets do you need?
It depends. Heavy squats and deadlifts usually take more sets than a light accessory lift. A lifter at 135 lb may need only the bar and two or three sets. A lifter at 405 lb may want five or six. If the bar feels slow or stiff, add a set. If you tire before the work set, cut one.
Why round to plates you can load?
Most gyms stock plates in fixed sizes. With plates down to 2.5 lb, the smallest jump in total weight is 5 lb. A warm up set of 163.5 lb is not real. The calculator gives you a weight you can put on the bar, so you do not need to do the sums mid-session.
A note on safety
This tool does arithmetic. It is not medical advice or coaching. Check that plates sit fully on the sleeve, use collars, and ask for a spotter on heavy sets. If you have pain or a health condition, talk to a doctor or qualified coach before you change your training.
