Sam Sulek vs Science-Based Bodybuilding: Is Instinctive Training Making a Comeback?
UPLIFT IRON CLUBThe Argument Sam Sulek Is Actually Making
Sam Sulek did not become a bodybuilding phenomenon by making every workout look like a controlled laboratory demonstration. His appeal comes from the opposite direction: long, conversational training videos, straightforward exercise choices and the sense that he genuinely enjoys the daily work. When he questioned the culture around science-based lifting, the interesting part was not a claim that research is useless. It was his frustration with the idea that one supposedly perfect method makes everyone else's approach wrong.
That distinction matters. Evidence-based training is a way of using the best available information to make decisions. Online, it can become a badge of superiority. A coach explaining why a certain range of motion might help is useful. A stranger declaring that a lifter's productive workout is worthless because the bench angle differs by five degrees is not. Those are two very different activities wearing the same scientific costume.
Sulek's other point is more personal: efficiency is not everyone's only goal. Some people want to finish training as quickly as possible. Others value the process itself, including trying a new machine, chasing a satisfying pump or spending an unhurried evening lifting. Enjoyment can support consistency, and consistency gives a sensible training plan time to work. It is perfectly reasonable to care about both muscle growth and liking the gym.
Still, the popularity of one athlete is not a controlled experiment. Sulek's physique cannot establish that every decision he makes is optimal, just as a carefully explained video cannot prove that one program is optimal for every lifter. His body reflects years of effort, individual characteristics and a context that may be very different from an ordinary recreational lifter's life. The useful question is narrower: which instincts help people train hard and consistently, which ones need a reality check, and how can lifters combine the two without turning every set into an argument?
Another mistake is confusing a critique of social-media behavior with a rejection of research. You can dislike smug optimization content while still accepting that progressive overload, fatigue management and exercise selection matter. Conversely, you can admire Sulek's enthusiasm without treating his hardest workout as a prescription. The best reading of this debate leaves room for both individual preference and evidence. Neither side needs to be a personality test.
Instinctive Training Still Has a Structure
Watch the exercises Sulek actually chooses and the supposed war between instinct and programming starts to look less dramatic. His sessions often feature familiar bodybuilding tools: pulldowns, rows, presses, curls, lateral raises and machines that let him focus on a target muscle. He may change the order or load according to how a movement feels that day, but that is not the same as wandering around randomly until exhaustion arrives.
Consider a back session built around a pulldown, a cable row and a unilateral pull. Each movement has a recognizable purpose. A pulldown trains shoulder adduction and elbow flexion with a large contribution from the lats. A row can emphasize upper-back muscles depending on the arm path and torso position. A single-arm variation lets the lifter adjust the line of pull and compare sides. The exact brand of machine matters less than whether the chosen movement can be performed comfortably, challenged and repeated.
The instinctive element often appears inside those decisions. Perhaps a chest-supported row bothers the shoulder, while a cable row feels stable and lets the back do the work. Perhaps a certain incline press is excellent one week and awkward the next. An experienced lifter can use that feedback to choose a productive alternative. Good training science does not require ignoring discomfort, anatomy or the equipment actually available.
Where instinct becomes less useful is when every feeling is treated as proof. A spectacular pump can occur after productive training, but it can also reflect short rests, carbohydrate availability or simply a new exercise. Soreness is not a reliable score for hypertrophy. And a movement feeling heavy does not necessarily mean the target muscle received a better stimulus. Keep the flexibility to choose exercises, then demand enough repeatability to learn whether the choices are working.
An easy test is to keep two or three anchor movements stable for a month while allowing accessories to change. If the main pulldown and row improve, you have useful evidence of progression. If every session changes every movement, it becomes harder to distinguish improvement from novelty. Experienced lifters may develop excellent judgment through repetition, but that judgment still benefits from a few consistent reference points. Instinct should refine a structure, not erase every opportunity to measure it.
Failure and Volume: What the Evidence Really Allows
The most heated part of this debate usually concerns effort. Sulek frequently pushes hard sets close to the point where another clean repetition is no longer available. He also uses partial repetitions, rest-pause efforts and other techniques that make the final minutes of a workout look brutal. That intensity can be productive, particularly on stable isolation machines. It does not follow that every set of every exercise should be taken to absolute failure.
Research comparing failure and non-failure resistance training does not establish a universal hypertrophy advantage for reaching momentary muscular failure. More recent analyses suggest that sets performed closer to failure may produce more growth on average, while the exact best stopping point remains uncertain. Those conclusions can coexist. A hard set with one or two good repetitions left is not automatically wasted, and the final impossible repetition is not a magical growth switch.
Exercise choice changes the cost. Reaching failure on a seated curl may be inconvenient and uncomfortable, but it is usually easy to stop. Grinding until technique collapses during a free-weight squat carries a different fatigue and safety profile. The goal is to challenge the intended muscle without turning every session into an injury lottery. Beginners in particular need time to learn what a genuinely difficult set feels like before chasing repeated all-out attempts.
Volume deserves the same nuance. More challenging sets can provide additional stimulus up to a point, but returns tend to diminish and fatigue accumulates. There is no reliable single number of weekly sets that fits every muscle, person or training phase. A useful starting approach for many recreational lifters is to distribute a manageable number of hard sets across the week, monitor performance and recovery, and add work only when there is a reason. Copying a professional bodybuilder's most exhausting session is not evidence that your own body will benefit from it.
Intensity should therefore be earned, not performed for an audience. Start with controlled repetitions, choose a load that allows the intended range, and take selected machine or isolation sets very close to failure when appropriate. Leave a little more room on technically demanding lifts. If a brutal set forces you to cut the next workout in half, its apparent toughness may be a poor bargain. The useful dose is the one you can recover from and progress beyond.
Rest intervals also change the equation. Very short breaks can make a set feel dramatically harder while reducing the load or repetitions available in subsequent sets. Longer rests on demanding compounds may preserve performance better. That does not mean everyone needs a stopwatch for every curl, but it does mean effort should be evaluated in context. A productive session is not necessarily the one with the highest heart rate or the longest period spent lying on the floor afterward.
Science-Based Training Is a Method, Not a Personality
Mike Israetel represents the side of bodybuilding that emphasizes structured decisions: exercise selection, useful ranges of motion, proximity to failure, progressive overload and managing fatigue across training blocks. He has also acknowledged that the online culture surrounding evidence-based fitness can become gimmicky or elitist. That is an important concession, because a scientific approach should be able to revise itself when better information or a different individual response demands it.
The caricature says science-based lifters are frightened of hard work and obsessed with obscure exercises. The reality is less entertaining. Good hypertrophy programming still asks people to lift challenging weights, accumulate meaningful sets and repeat that work over time. An exercise chosen for stable resistance and a tolerable joint position can be brutally hard. A planned deload can make the next month more productive rather than proving someone has gone soft.
Research is especially valuable when instinct produces a convincing but misleading story. The pump may feel incredible after thirty short-rest sets, yet the next two sessions may suffer. An unusual cable angle may feel revolutionary for a week, yet add nothing beyond a simpler movement. Tracking results and considering broader evidence can prevent those sensations from becoming expensive habits. Science offers guardrails, not a guarantee that every recommendation is perfect.
Equally, research cannot select your favorite chest machine, predict exactly how your shoulder will respond today, or make you enjoy a program you dread. Studies describe patterns across groups under particular conditions. Applying those patterns to a person requires judgment, context and feedback. That is why the best coaches combine principles with observation rather than prescribing identical workouts to everyone.
The strongest position in this argument is not that Sulek wins and Israetel loses, or vice versa. It is that neither a charismatic physique nor an academic credential should end the conversation. Ask whether the recommendation makes biological sense, whether the lifter can perform it well, whether progress can be measured and whether the approach is sustainable. Those questions are far more useful than choosing a team.
Science is also provisional. An exercise study might involve untrained participants, a short intervention, or a specific measurement of muscle size. A result that is interesting in that setting may not translate neatly into a universal rule for advanced lifters. The sensible response is neither to ignore the study nor to obey it without context. Use it to update the range of plausible options, then test those options with a repeatable training plan and a realistic time horizon.
Why Sulek's Enjoyment-First Mindset Has Staying Power
There is a reason people watch long, unpolished bodybuilding sessions even when the exercise list contains nothing revolutionary. Sulek makes the process itself interesting. He talks through decisions, reacts to how sets feel and returns to the same basic work. That creates a very different message from a feed in which every workout promises a secret technique that will double your gains by Friday.
Enjoyment is not a substitute for training stimulus, but it can be an important ingredient in adherence. A program that looks optimal on paper and is abandoned after three weeks is not optimal in practice. Someone who genuinely likes cable rows may train their back more consistently with them than with a theoretically fashionable variation that causes discomfort or requires equipment their gym never has. Repetition creates skill, confidence and a useful record of progress.
The trap is treating enthusiasm as permission to ignore recovery. A long session can be fun and still contain more sets than the lifter can recover from. A daily gym habit can support mental wellbeing and still crowd out sleep, meals or important relationships. If performance steadily declines, joints become irritable and motivation turns into dread, the answer is not automatically another heroic set. The plan may need less volume, a lighter week or a different exercise.
Professional bodybuilding also creates unusual incentives. An athlete preparing for competition may tolerate demanding schedules and trade-offs that make little sense for someone training around work, study or family. The presence of elite genetics, extensive experience and individual recovery differences means copying a star's total workload is not a fair test of your own commitment. Take the attitude toward showing up, not the assumption that every training variable must match.
The practical takeaway is refreshingly simple: build sessions around exercises you enjoy enough to repeat, but keep them challenging and purposeful. Let the training feel satisfying without requiring it to feel punishing. If the gym is part of your life for the next decade, an approach you look forward to has a genuine advantage over one that turns every session into a joyless exam.
That enjoyment can coexist with restraint. A lifter who loves long sessions can reserve extra time for warm-ups, practicing poses or trying a new accessory without making every minute a maximal-effort working set. A lifter who prefers shorter sessions can leave after completing the important work. Neither person needs to prove devotion by copying someone else's clock. Sustainable training respects the individual's reasons for being there.
Borrow the Feel, Not Every Set: A Safer Translation
Most lifters can borrow the useful parts of Sulek's approach without reproducing his entire schedule. Begin with a stable exercise for each major movement pattern. For the upper body, that might mean an incline press, a chest-supported or cable row, a pulldown and a lateral raise. For the lower body, use a squat or leg press, a hip hinge and a leg curl. These are examples, not commandments; choose movements that suit your joints, equipment and experience.
Use feel to refine the execution. On a pulldown, choose a grip and torso angle that let you control the lowering phase and pull without wrenching the shoulders. On a lateral raise, reduce the load if the movement becomes an uncontrolled whole-body heave. On a press, select a range of motion that challenges the target muscles without repeatedly provoking pain. The sensation of muscular effort can guide adjustments, but pain is not a sign that the set is more effective.
Then give the choices a measurable structure. For a row, try three working sets of eight to twelve controlled repetitions. Keep the same exercise for several weeks. When all three sets reach the upper end with similar technique and effort, add a small amount of weight. If performance drops, ask whether sleep, food, rest intervals or accumulated fatigue changed before deciding that the exercise has stopped working. The log prevents today's mood from rewriting the entire plan.
Use high-intensity techniques selectively. A final drop set on a cable curl may be a fun way to finish arm training; doing drop sets after every heavy squat is a different proposition. Start with one optional intensity technique on a stable accessory movement and judge whether it improves the session without damaging the next one. If it only creates soreness and longer recovery, remove it. A method does not earn a permanent place because it looks dramatic on camera.
Finally, keep weekly workload realistic. Two or three exposures per muscle group can distribute hard sets more comfortably than cramming everything into one marathon, although frequency itself is not magic when total work is matched. Adjust upward only when progress and recovery justify it. Instinct should help you choose the route through a workout; the results should tell you whether the route is worth keeping.
Make a distinction between discomfort from effort and discomfort from a joint or tendon. A hard quadriceps set can burn while the knee remains comfortable. A sharp pain that changes your movement is a reason to stop or modify the exercise, not a challenge to push through. If an exercise repeatedly provokes symptoms, a different movement pattern or professional assessment may be appropriate. Training intelligently means staying available for the next session.
A Four-Week Hybrid Plan That Measures What Matters
Here is a practical way to test the middle ground without pretending one template fits everyone. Pick three or four training days per week. On each day, include a small number of main movements and a few accessories. For example, an upper-body session might use three sets of incline press, three sets of row, two sets of pulldown and two sets of lateral raises. A lower-body session might use three sets of leg press, two sets of Romanian deadlift, two sets of leg curl and two sets of calves. Choose rep ranges that let you work hard with clean technique.
During week one, learn the movements and establish repeatable starting loads. Finish most sets with roughly one to three good repetitions in reserve, using a little more caution on demanding free-weight lifts. Record weights, reps and any joint discomfort. Notice which variations feel stable and which require constant adjustment. This is where instinct gets a vote: keep the exercises that suit you, not merely the ones that look impressive.
In week two, repeat the main movements and aim for one extra clean repetition where performance allows. If a machine press improves from three sets of eight to sets of nine, nine and eight at the same load, that is useful progress. Do not force an increase when sleep or recovery has clearly been poor. On one low-risk accessory, you may try a harder final set and observe whether it changes the next session.
In week three, review the log. If most exercises are improving and soreness resolves normally, keep the plan. If an exercise is stagnant but everything else is moving, adjust that exercise rather than rebuilding the whole week. If several lifts are declining, consider reducing total sets or adding rest. Do not confuse a one-day dip with a genuine trend. Good judgment needs more than one data point.
In week four, compare the first and final sessions. Look at repetitions at a given load, technique quality, consistency, recovery and whether you still want to train. Keep the successful movements for another block; replace only what has a clear reason to change. That is the real synthesis: enthusiasm chooses a sustainable way to work, evidence keeps the claims modest, and a simple record shows whether the work is producing results. No tribal allegiance required.
Use the same basic review whether you are training for bigger arms, stronger legs or general fitness. Record the few measures that actually inform decisions; do not turn the log into a second full-time job. If the plan is enjoyable and the numbers trend upward, resist the temptation to overhaul it because a new video declares your favorite exercise obsolete. If results stall for weeks, change one variable at a time. The goal is a feedback loop that stays useful long after the online argument has moved on.
