How Much Warm-Up Is Enough? Dr. Pak’s Case Against Turning Preparation Into a Workout
UPLIFT IRON CLUBThe Warm-Up Has One Job: Make the Training Better
Dr. Pak’s broader training philosophy is built around a useful question: what is the minimum dose that produces the result you actually want? His 2026 book Train Smarter, Not Longer applies that idea to resistance training as a whole, but it is especially useful for warm-ups. Preparation earns its place when it makes the work sets better. Once it starts consuming time and energy without improving readiness, it has drifted from preparation into extra training.
That does not mean “skip the warm-up.” It means define the outcome. Before a normal lifting session, you want to feel physically warm, move comfortably through the positions required by the first exercise, and arrive at the first work set with the movement pattern rehearsed. You do not need to win a mobility contest, accumulate a pump in six activation drills, or prove your conditioning on the bike first.
The research supports a practical rather than ritualistic view. A 2026 scoping review found that resistance-training warm-ups can improve several measures of dynamic strength performance, including squat and leg-press one-repetition maximum, bar velocity and repetition performance under some protocols. Earlier systematic-review work also found that specific warm-ups can be useful, although the exact best protocol is not settled. The message is not that more warming up is always better. It is that preparation should match the task.
For a healthy lifter on an ordinary day, think in layers: a short general warm-up if you need it, targeted mobility only where it solves a real restriction, then progressive sets of the lift you are about to train. If you already walked to the gym and feel warm, layer one may be nearly unnecessary. If it is cold, you have been sitting all day, or the first lift is technically demanding, it can be more valuable.
General Warm-Up: Enough to Raise Readiness, Not Create Fatigue
The general warm-up is the easiest part to overcomplicate because almost anything can look productive. Five minutes on a bike becomes ten; then come foam rolling, band work, crawling, breathing drills and a circuit that would qualify as a small conditioning session. The better question is whether you actually need all of it before today’s training.
If you arrive cold or stiff, a few minutes of easy cyclical work can be useful. Walk briskly, pedal, row or use a treadmill at a pace that raises temperature without making your legs heavy. You should be able to breathe comfortably. The endpoint is not a calorie target or a puddle of sweat; it is simply feeling more ready to move. A 2025 meta-analysis found that increased muscle temperature was associated with better rate-dependent contractile qualities such as power and rate of force development, while effects on maximum force were much smaller. “Getting warm” is one ingredient rather than the entire recipe.
Duration should respond to context. A lifter training first thing on a winter morning may appreciate five to eight easy minutes. Someone who just walked twenty minutes to the gym may already have accomplished the general part. A high-rep machine session usually needs less ceremony than a heavy squat single. Older lifters, people returning from a layoff and anyone managing a known issue may prefer a slower build, but that still does not make a universal twenty-minute routine mandatory.
Use a simple test: after the general warm-up, do you feel warmer and looser without feeling trained? If yes, move on. If your breathing is elevated, quads are burning or you are already negotiating with yourself about the first squat set, the dose was too high for a strength-session warm-up.
Mobility and Activation Should Solve a Specific Problem
Mobility work is useful when it changes something you need for the session. That is a much higher bar than “this drill looks athletic.” If your ankles are limiting squat depth, a short ankle drill before squatting has a clear job. If your shoulders feel restricted before overhead pressing, controlled shoulder and thoracic movement may improve the positions you need. If you already move comfortably through the exercise, ten extra drills may add complexity without adding readiness.
The same applies to activation. A banded lateral walk can be useful when it helps a lifter feel and control the hips before lower-body work. A few scapular movements can help someone settle into pressing or pulling. But activation work is not magical insurance, and the target muscle does not need to be exhausted to prove it is “awake.” The goal is better movement in the main exercise, not fatigue in the preparatory drill.
This is where lifters can accidentally turn warm-ups into workouts. Three rounds of glute circuits, high-rep band pull-aparts, loaded carries and long mobility flows can create enough local fatigue to alter the session they were supposed to support. Keep the dose small and retest. Do one drill, then squat with the empty bar. If the position is better, great. If nothing changed, adding three more rounds because an infographic said so is hard to justify.
Long static stretching deserves context too. Short holds are not automatically disastrous, but if maximum strength or power is the immediate goal, dynamic movement and exercise-specific preparation generally make more sense than prolonged passive stretching immediately before the lift. Save long flexibility sessions for when flexibility itself is the training target. Warm-up mobility should be a screwdriver, not a junk drawer: use the tool that fixes the problem in front of you.
Ramp-Up Sets Are the Most Specific Preparation You Can Do
Once you touch the exercise itself, the warm-up becomes much more specific. For a barbell squat, that means squatting. For a bench press, it means benching. Progressive ramp-up sets rehearse the exact grip, stance, range of motion, bracing and equipment setup you are about to use while gradually exposing you to heavier load.
This is also where the evidence is most useful. The 2021 systematic review of resistance-training warm-ups found mixed results across protocols, but specific warm-ups—particularly those using meaningful loads—were among the strategies most likely to help maximal strength or repetition performance. The newer 2026 scoping review similarly reported benefits from progressive-intensity warm-ups across outcomes including lifting velocity and total repetitions. You do not need a perfect percentage chart to use the principle.
Start light enough to move freely and take more repetitions there. As load rises, reduce the reps. If your squat work sets are 140 kilograms for five, you might use the empty bar for several controlled reps, then 60 kilograms, 90, 115 and perhaps a low-rep set around 125–130 before beginning the work. The exact jumps depend on strength, exercise, equipment and how you feel. A 60-kilogram work set needs fewer steps than a 250-kilogram work set.
The key is preserving energy. Warm-up sets should increasingly resemble the work set in technique and intent while decreasing in repetition count. Doing ten reps at every step is a good way to arrive at the important set with avoidable fatigue. Conversely, jumping from the empty bar straight to a near-limit load saves time but gives you little opportunity to assess readiness or groove the movement.
Treat the ramp as information. If a normally easy load feels awkward, take another small step or address the specific issue. If every set is crisp, keep moving. The barbell itself is often the best diagnostic tool in the warm-up.
Heavy Days Need More Ramping—Not More Random Stuff
A heavy day usually needs more warm-up than a light machine session, but most of that extra preparation should come from progressively approaching the task. If you are going to bench a heavy triple, the useful extra work is likely another carefully chosen bench warm-up set—not five additional shoulder drills that have little resemblance to the lift.
The number of ramp sets grows naturally with the gap between an empty implement and the working load. A strong deadlifter cannot sensibly jump from 60 kilograms to 250 in one move, while someone curling a 12-kilogram dumbbell may need almost no formal ramp. Large compound lifts also let you gather useful information about technique, joint comfort and bar speed before the expensive sets begin.
Near the top, keep reps low. Singles or doubles at submaximal loads can make sense before heavy strength work because they expose you to meaningful weight without creating much volume. For hypertrophy work in moderate rep ranges, you often need less elaborate potentiation: enough progressive loading that the first work set does not feel like a surprise is usually sufficient.
Rest matters as well. A warm-up does not have to be rushed simply because the weights are lighter. As the ramp gets heavier, allow enough time that the previous set does not turn the next one into conditioning. At the same time, you do not need five-minute rests after the empty bar. Rest should scale with the demand.
Dr. Pak’s minimum-dose lens is useful because it shifts the goal from collecting warm-up activities to removing uncertainty. By the final ramp set you should know that the movement feels good, the load is moving normally and you are ready to perform. Once you have that answer, continuing to warm up is usually just spending energy you wanted for the workout.
A Minimum-Effective Warm-Up You Can Actually Use
For most normal lifting sessions, a practical warm-up can be simple. First, ask whether you are already warm. If not, use roughly three to five minutes of easy cardio or general movement. Second, identify one or two positions that actually need attention for the first lift. Spend a few minutes on targeted dynamic mobility or activation only if it improves those positions. Third, begin exercise-specific ramp-up sets, increasing load while reducing reps until you are close enough to the working weight that the next set feels predictable.
That framework can take five to ten minutes on a straightforward day and longer before genuinely heavy or technically demanding work. The clock is not the primary target. Readiness is. A good warm-up ends when additional preparation has diminishing returns.
You can also shorten later warm-ups within the same session. If you have already squatted hard, your body temperature does not reset to zero before leg press. You may need one or two feeler sets to learn the machine and approach the working load, not a repeat of the entire opening routine. The same logic applies when moving from bench press to a chest machine or from rows to curls. The more overlap there is, the less general preparation you usually need.
Adjust upward when the situation actually changes: very cold conditions, a new exercise, unusually heavy work, stiffness after travel, a previous injury that benefits from a known preparation strategy, or a session where the first ramp sets simply feel wrong. Adjust downward when you arrive warm, the exercise is simple, loads are modest and movement feels excellent.
The final rule is brutally simple: your warm-up should leave you more prepared than when you started and less fatigued than if you had simply begun training. If the first work set is consistently worse because your preparation takes thirty minutes and contains a miniature workout, cut the ritual. Keep what changes performance, comfort or confidence. Drop what merely makes the warm-up look sophisticated. Preparation is successful when it disappears into a better training session.
