Warm-Up Sets Before Heavy Lifting
Quick answer
A warm-up for a heavy lift is a short series of sets that groove the movement and prepare you for the first work set. Start at the bar. Add weight. Cut the reps. Rest a little longer as it gets heavy.
The sets are not there to tire you out. If the warm-up is a grind, the work sets will be worse. Use the warm-up calculator to turn a target into plate-friendly jumps.
Estimates only. Testing a true max carries risk; use a spotter or safety arms. Not medical advice.

What do the jumps look like?
A practical pattern, not a law: empty bar, then about 40%, 55%, 70%, 80%, and 90% of the work-set weight, with reps falling as the load rises. Something like 10, 5, 3, 2, 1 is enough for a heavy squat or bench. A deadlift often needs fewer reps at the light end because the back does not enjoy ten sloppy pulls.
Those percents are of the work set you are about to do, not of your all-time max, unless the work set is the max. The calculator on this site uses the bar weight for the unit you picked: 20 kg or 45 lb, and you can change it.
How long do you rest?
Long enough that the next set is not a recovery test. A minute is plenty between empty-bar sets. Two or three minutes, sometimes more, before a heavy single. The clock is a tool. Your bar speed is the feedback.
Do not fill the rest with a hard accessory. Save rows and curls for after the main lift, or do them light enough that they do not steal the session.
Should every lift warm up the same way?
The pattern is the same. The specific warm-up is the lift itself. A set of leg extensions is not a squat warm-up. A push-up is not a bench warm-up. You can do them if you like how your joints feel. The sets that matter are the ones that look like the work.
Overhead press and bench need the shoulders to actually visit the position you are about to load. Olympic lifts need lighter technique reps, not a heroic set of ten snatches. The homepage caps those estimates for a reason.
When should you warm up longer, or stop?
Longer if the gym is cold, you are older, or the first work set is a single. Shorter if the work is a machine at a moderate weight and you already squatted. There is no prize for a 25-minute warm-up before a set of curls.
Stop the ramp if a warm-up set moves like a max. Change the work set. The plan was wrong, or the day is worse than the plan. Both happen. Testing a single is the day to be strictest about this.
Plate math is how those percents become iron. A test day uses the same ramp, with less room for a sloppy jump: how to test a single.
Key takeaways
- The empty bar is the start, not the whole warm-up.
- Jumps get heavier and the reps get shorter.
- The last warm-up should sit near the work set.
- A warm-up that grinds has already used the session.
FAQ
Is the empty bar enough?
Only for a light session. A heavy work set needs heavier jumps in between, or the first work set becomes the warm-up.
Do warm-up sets count as volume?
They are work. They are not the same stress as a hard set of five. Do not log them as the session and skip the sets you came to do.
What percent should the last warm-up be?
Near 80 to 90 percent of the work set, for a single or a double. Close enough that the work set is not a shock.
Can I warm up in a different unit?
The plates change. The idea does not. Stay in one unit for the session so you do not misload.
What if I share a bar?
Warm up with what you can load without stripping someone else's plates every minute. Fewer jumps, same idea: light, then medium, then one set close to the work.
