Warm-up sets: how do I warm up properly?
The warm-up calculator builds a sequence of warm-up sets up to your working weight, rising load with dropping reps.

Warming up is part of the lift, not a bonus before it. Build the ramp into your session protocol.
Method
How the calculation works
The ramp starts with the empty bar and climbs in percent of the working weight (about 50 %, 70 %, 85 %, 92 %) while reps drop. This builds progressively toward the working load without adding much extra volume.
Rest 30-90 seconds between warm-up sets and 2-3 minutes before the last heavy single. For lighter work weights, intermediate steps naturally drop.

How reliable is this estimate?
Medium
Warm-up schemes are proven rules of thumb. How much warming up you need depends on the lift, technique, daily form and environment.
Interpretation
How to read your result
The warm-up is not an endurance segment. Reps drop with rising load so you enter the first work set fresh.
For follow-up lifts in the same muscle group, 1-2 short warm-up sets are enough. Full ramps belong before the heaviest lift of a group.
Limits
Where this calculator ends
The percentages are guidelines. For extremely heavy work weights, add a set if in doubt; for very light work weights, fewer sets are fine.
Longer static stretching immediately before maximal strength efforts can reduce acute performance. Use the specific exercise ramp as a starting point and adapt any additional mobility work to your needs.
Common mistakes
Common mistakes
- 01Shortening the warm-up before heavy sets because time is tight.
- 02Doing so many warm-up sets that the work sets suffer.
- 03Taking warm-up sets close to muscular failure.
- 04Using the same scheme for every exercise regardless of load and technique.
- 05Counting warm-up sets as working volume.
Example
A worked example
Working weight 100 kg on a 20 kg bar
Ramp: 20 kg × 8-10, 50 kg × 5, 70 kg × 3, 85 kg × 2, 92.5 kg × 1, then 100 kg as first work set. Short rests between warmups, ~2-3 minutes before the 92.5 kg single.
FAQ
Frequently asked questions
- How many warm-up sets do I need?
- Usually 3-5. For very heavy work weights 5-6, for light ones 2-3 is enough.
- How heavy should warm-up sets be?
- Rising in percent of the working weight (~50 → 70 → 85 → 92 %) with dropping reps. Goal: prime, don't fatigue.
- Do I have to warm up for every exercise?
- Yes for the heaviest lift of each muscle group, full ramp. For follow-up lifts in the same group, 1-2 short sets suffice.
- Why shouldn't warm-up sets be fatiguing?
- Because you want to enter the work set fresh. Too many reps or too flat a ramp burns strength you need for the actual sets.
- How long should I rest between warm-up sets?
- 30-90 seconds on lighter sets, 2-3 minutes before the last heavy single. The CNS benefits from a short pause before the target work.
