This guide explains the difference between warm-up and working sets, how many you actually need, and how to structure them for strength, muscle gain, and time efficiency.
Warm-up sets prepare joints, muscles, and your nervous system; working sets create most of the strength and muscle gains.
Increase load gradually during warm-ups, while keeping reps low and away from fatigue.
Most lifters need 2–5 warm-up sets and 2–5 working sets per main lift, depending on load, experience, and time.
This article separates warm-up and working sets by intent, fatigue level, and load relative to your working weight. It then provides step-by-step templates for common goals (strength, muscle gain, general fitness) and typical lifts (squat, bench, deadlift, presses). The recommendations draw on principles of progressive overload, motor learning, and joint preparation used in strength and conditioning.
Many people either skip warm-ups and feel stiff or overdo them and waste energy before working sets. Understanding how to structure both types of sets lets you lift heavier, stay safer, and get better results in less time.
Warm-up sets exist to prepare: increase core temperature, groove technique, and wake up your nervous system for the movement pattern. Working sets exist to provide a training stimulus: enough load, effort, and volume to drive strength, muscle, or power adaptations.
Great for
Warm-up sets use lighter loads that ramp up toward, but do not reach, your working weight. Reps are kept well away from failure. Working sets use your target training load for the day and are taken to a planned effort level (for example RPE 7–9, leaving 1–3 reps in the tank, depending on the goal).
Great for
Your warm-up needs depend on: 1) Load: heavier working sets require more ramp-up steps. 2) Exercise: big compound lifts need more prep than small isolation work. 3) Training age: older or stiffer lifters may need more gradual ramping. 4) Environment: cold rooms demand longer warm-ups than warm gyms. 5) Time available: on busy days you can trim some steps but keep at least one or two ramp-up sets.
Great for
For main barbell lifts (squat, bench, deadlift, overhead press), most lifters do well with 2–5 ramp-up sets after the empty bar. For secondary compound lifts (rows, lunges, RDLs), 1–3 warm-up sets usually suffice. For isolation movements (biceps curls, triceps extensions, lateral raises), 0–2 light sets are often enough, especially later in the workout when you are already warm.
Great for
For pure strength (heavy loads, low reps), most lifters progress well with 2–5 working sets per main lift in a session. Common schemes: 3x3, 5x3, 4x4, or 5x2 at 75–90% of one-rep max, usually at RPE 7–9 (1–3 reps in reserve). Volume is moderate; intensity is high.
Great for
For hypertrophy, 3–5 working sets per exercise is typical, at 6–12 reps and roughly RPE 7–9. You might do 8–15 hard sets per muscle group per week, split across multiple exercises. The exact number depends on your recovery, experience, and exercise selection.
Great for
Suppose your working sets are 4x5 at 100 kg. A simple warm-up progression could be: 1) Empty bar (20 kg) x 10. 2) 40 kg x 5–6. 3) 60 kg x 4–5. 4) 80 kg x 3. 5) 90 kg x 2. Then do your working sets: 4 sets of 5 at 100 kg. Only the 4x5 count as working sets; the others are warm-ups.
Great for
Working sets: 3x6 at 80 kg. Warm-up: 1) Empty bar x 10–12. 2) 40 kg x 6–8. 3) 60 kg x 4–5. 4) 70 kg x 2–3. Then 3x6 at 80 kg, RPE 7–8. If a day is short on time, you might skip the 70 kg warm-up and go straight from 60 kg to 80 kg, as long as it feels smooth and safe.
Great for
A typical flow: 1) General warm-up (3–8 minutes of light cardio and mobility). 2) Movement prep (1–2 light sets with the empty bar). 3) Warm-up sets ramping toward working weight. 4) Working sets at your planned load and rep scheme. 5) Accessories and conditioning. This structure ensures you are primed for your heaviest work, then use remaining energy for secondary exercises.
Great for
Rate of Perceived Exertion (RPE) or Reps In Reserve (RIR) helps you label sets clearly: warm-ups stay around RPE 4–6 (3+ reps in reserve), while working sets live around RPE 7–9 (1–3 reps in reserve). This mental separation helps you keep warm-ups crisp and working sets challenging but not reckless.
Great for
Doing too many reps or sets close to failure before your planned working sets leaves you tired when it counts. Keep warm-ups submaximal and stop well before fatigue. If a warm-up set feels like a grind, treat it as a sign to adjust the plan, not push harder.
Great for
Skipping gradual load increases and jumping from the empty bar to a near-max weight stresses joints and connective tissue. It also feels heavier than it needs to because your nervous system is not primed. Always include at least a couple of intermediate steps before heavy working sets.
Great for
Warm-up sets and working sets sit on the same continuum of effort, but their roles are distinct: one prepares the system, the other challenges it. Treating them differently in planning and tracking gives you clearer feedback and better progress.
Efficient lifters use the minimum effective warm-up to feel ready, then channel most of their time and energy into high-quality working sets. This balance maximizes results without extending sessions or increasing injury risk.
Frequently Asked Questions
Generally, no. Only sets that are challenging enough to be within about 3 reps of failure at a meaningful load are counted as working sets for hypertrophy. Warm-up sets are usually too light and too easy to create a significant growth stimulus, so track them separately.
Most beginners do well with 1–3 warm-up sets after the empty bar for main lifts. For example, empty bar x 10, a light set x 8, then a slightly heavier set x 5 before starting working sets. The focus is on learning technique and feeling comfortable, not on many warm-up steps.
It should feel substantial but not difficult—around RPE 5–6. You want to feel the weight and dial in your technique without straining. If your last warm-up feels like a near-max effort, it is too heavy or you are doing too many reps at that load.
Yes, the same load progression can usually work whether you are doing 3s, 5s, or 8s as working sets. What changes is the number of warm-up reps: use more reps on the light sets and fewer (2–3) on the heavy warm-up sets, so you arrive fresh at your working sets.
Warm-up sets can use short rest periods of 30–60 seconds, as they are not very fatiguing. Between working sets, rest 2–4 minutes for heavy strength work and 1–2 minutes for moderate-weight hypertrophy work, adjusting based on how recovered and ready you feel.
Warm-up sets and working sets serve different purposes: one primes your body and brain; the other delivers the training stress that drives progress. Structure your sessions so you ramp up smoothly with low-fatigue warm-up sets, then focus your time and effort on a manageable number of high-quality working sets. As you get stronger, adjust the number of steps and the loads, but keep the principle constant: prepare efficiently, then train with intent.

Warm-up volume is low and controlled to avoid tiring you out. Most lifters need only 10–25 total warm-up reps for a big lift. Working sets contain the majority of total volume and are where you accumulate most training stress, which you then recover from and adapt to.
Great for
Warm-ups are a great time to emphasize slower, controlled eccentrics and tight technique, especially on the first few sets with the empty bar. Working sets can use your normal, more explosive tempo while keeping control, as long as technique stays solid under load.
Great for
Warm-up sets are not usually counted in weekly training volume. Only working sets at or near your target intensity are tracked for progression. This keeps programs comparable over time and ensures you do not inflate your volume with low-impact work.
Great for
As you ramp up, keep warm-up sets submaximal: the last warm-up should feel like RPE 5–6 (about 4–5 reps left in the tank). Do fewer reps as load increases. Early warm-ups can be 5–8 reps; later ones are often 2–3 reps to avoid fatigue while letting you feel the heavier weight.
Great for
You can often reduce warm-up volume when the load is light to moderate (for example sets of 8–12 at 60–70% of max), when you are already warmed up from previous similar exercises, or on smaller isolation lifts. You should not skip warm-ups entirely for heavy compound lifts, max-effort work, or when coming back from injury.
Great for
If your goal is to be stronger, healthier, and time efficient, 2–3 working sets per main lift is often enough, performed 2–3 times per week. Think 2–3 sets of 5–10 reps at a challenging but controlled effort. Consistency matters more than squeezing in extra sets.
Great for
If your last working sets are much weaker than your first, technique breaks down, or you feel constantly sore and fatigued between sessions, you may be doing more working sets than you can recover from. Reduce total working sets or average RPE for a block and re-assess performance.
Great for
Working sets: 5x3 at 150 kg. Because deadlifts stress the back and nervous system heavily, use more small jumps: 1) 60 kg x 6. 2) 90 kg x 4–5. 3) 110 kg x 3. 4) 130 kg x 2. 5) 140 kg x 1. Then 5x3 at 150 kg. Keep warm-up reps snappy and do not grind to avoid early fatigue.
Great for
Working sets: 3x10 per side. Warm-up may only need 1–2 sets: 1) Very light weight x 10–12. 2) Slightly heavier x 6–8 if needed. Then move into your working weight. Since the overall load is lighter, you can warm up faster than with heavy barbell movements.
Great for
Once you are fully warmed up from your main lift, later exercises usually need less ramping. For example, after squats, your leg press or lunges may need just one lighter feeler set before working sets. This keeps the session efficient while still respecting movement prep for each new pattern.
Great for
To stay efficient: combine general warm-up with your first movement prep (e.g., brisk walk plus empty bar squats), make slightly larger load jumps if the weight is submaximal, keep warm-up rest periods short (30–60 seconds), and cap total warm-up time to around 10–15 minutes for most sessions.
Great for
If you log all warm-up sets as equal to working sets, your weekly volume numbers become misleading. Track working sets separately so you can progressively overload the stress that actually drives adaptation, while keeping warm-up volume stable.
Great for
Different movements and loads need different warm-ups. Squats and deadlifts need more ramp-up sets than curls or lateral raises. Adjust the number and size of your warm-up steps to the specific lift instead of copying the same pattern across the board.
