How Many Warm-Up Sets Before Working Sets? A Simple Ramp-Up Chart and Rules

For heavy compound lifts like the squat, bench press, deadlift, or overhead press, most lifters need 2 to 4 warm-up sets before their first working set. For secondary exercises and isolation movements done later in the session, you need 0 to 1 warm-up set, because your core temperature and joints are already warm.

The goal of a warm-up set is strictly preparation, not conditioning. You want to groove the motor pattern, lubricate the joint capsules with synovial fluid, and potentiate your central nervous system for heavy loads. If your warm-up sets make you sweat through fatigue or burn out your muscles, you are not warming up; you are stealing reps from your working sets.

How many warm-up sets do you need by exercise type?

The number of warm-up sets you need depends on two factors: where the exercise sits in your workout and how heavy the load is relative to your bodyweight.

If your working weight on a lift is relatively light (such as a 95 lb or 45 kg bench press), 1 or 2 warm-up sets is enough. If your working weight is 315 lb or 140 kg, you need 4 or 5 ramp-up sets simply because jumping straight from an empty bar to 315 lb places excessive shock on tendons and connective tissue.

The 4-step warm-up ramp-up formula

When preparing for your primary compound lift of the day, use this four-step pyramid. Notice how the reps drop as the weight climbs. This keeps muscular fatigue near zero while preparing your nervous system for the heavier load.

Step 1: Empty Bar (or 45% to 50% working weight) x 8 to 10 reps
Step 2: 60% working weight x 4 to 5 reps
Step 3: 75% to 80% working weight x 2 to 3 reps
Step 4: 85% to 90% working weight x 1 rep (potentiation single)
Working Sets: 100% target working weight x prescribed reps

Step 4 is what powerlifters call an "acclimation single." Doing one crisp, explosive repetition at roughly 90% of your target load tells your nervous system what heavy weight feels like in your hands or on your back. Because you only perform a single rep, you generate almost no lactic acid or metabolic fatigue, but your first working set will feel significantly lighter.

Warm-up ramp-up chart: percentages and weights

Here is a practical reference chart for common barbell working weights in both pounds (lb) and kilograms (kg). All calculations assume a standard 45 lb or 20 kg Olympic barbell.

Imperial loading chart (pounds)

Metric loading chart (kilograms)

For lifts where your working weight is under 135 lb (60 kg), such as an overhead press or barbell curl, two ramp-up sets are sufficient: the empty bar for 8 reps, followed by roughly 70% of your target for 3 to 4 reps.

Do warm-up sets count toward muscle volume?

No. Warm-up sets do not count toward your weekly muscle-building volume.

Hypertrophy research shows that muscle growth requires mechanical tension and high motor unit recruitment. That stimulus only occurs when sets are taken close to muscular failure, typically within 0 to 4 reps in reserve, or an RPE of 6 to 10 on an RPE chart for lifting.

Warm-up sets operate at an RPE of 1 to 5. While they circulate blood and rehearse technique, they recruit primarily low-threshold motor units that do not experience enough mechanical tension to grow. Counting warm-up sets as working volume creates two common training mistakes:

1. Volume illusion: You think you did 16 sets for chest this week, but 8 of them were warm-up sets. Your actual muscle-building stimulus was only 8 sets, which may be below your threshold for progress.
2. False progression tracking: If you log a 135 lb warm-up as a working set, your workout tracker might assume your strength declined from last week's 225 lb session.

Always separate your warm-up sets from your working sets. Count only your hard working sets toward your weekly target, whether you track volume with a paper notebook or check your sets against how many exercises per workout.

How to log warm-ups and working sets in PeakBFF

When you lift in PeakBFF, your working sets drive your training volume and auto-progression. Here is how to keep your warm-ups and working sets organized:

1. Open your program or start an empty workout. When you tap into an exercise, PeakBFF prefills the weight and reps from your previous completed working sets so you know your target load immediately.
2. While warming up, tap Load with plates in the weight picker sheet. If you are calculating jumps between 135 lb, 185 lb, and 225 lb (or 60 kg, 80 kg, and 100 kg), the visual plate calculator shows the exact plates needed per side so you never have to do mental gym math between sets.
3. Log only your true working sets as completed. PeakBFF uses these completed working sets to update your rolling weekly muscle-volume map in the Body view.
4. When you hit the top of your target rep range across all working sets, a Try more chip appears. It reviews your progression and suggests whether to add reps or increase weight next session, without being skewed by lighter warm-up sets.

If you want to review how your working weights have climbed over time, see how to track progressive overload and how to calculate your one-rep max.

Many PeakBFF features are free for basic users, including workout logging, the plate calculator, and food logging. Plus unlocks custom programs and the full volume analysis, and costs $49.99 per year on the US App Store (as of November 2026).

Save this checklist on your phone or in your gym bag to keep your warm-ups fast and disciplined:

Primary Compound Exercise: ____________________
Target Working Weight: ______ lb / kg

[ ] General prep: 3 to 5 minutes light cardio or dynamic joint circles
[ ] Warm-up Set 1: Empty bar x 8 to 10 reps (focus on smooth bar path)
    -> Rest 30 to 45 seconds (load plates)
[ ] Warm-up Set 2: ~60% target x 5 reps (speed on the way up)
    -> Rest 45 to 60 seconds (load plates)
[ ] Warm-up Set 3: ~75% target x 3 reps (brace core hard)
    -> Rest 60 to 90 seconds (load final plates)
[ ] Warm-up Set 4: ~90% target x 1 rep (crisp, explosive single)
    -> Rest 2 full minutes

[ ] Working Sets: 100% target weight (log every set)

How to set your warm-up routine in one minute

1. Check your target working weight for your first compound lift.
2. If working weight is over 135 lb (60 kg), plan 3 to 4 warm-up sets using the 50%, 65%, 80%, and 90% single progression.
3. If working weight is under 135 lb (60 kg), take 1 or 2 quick sets with the empty bar and a 70% load.
4. Keep rest periods short (under 60 seconds) until your final single.
5. Do not count warm-ups toward your working volume, and move straight to 0 or 1 warm-up set for all later exercises.
