The Correct Way to Build Strength, Endurance & Flexibility at Any Age | Pavel Tsatsouline

Pavel Tsatsouline frames strength as the foundation of fitness rather than a synonym for muscular size. Andrew Huberman opens the discussion by distinguishing the pursuit of strength from hypertrophy and asks how strength, endurance and other physical qualities fit together. Tsatsouline’s answer, attributed to Professor Leonid Matveev, is that strength supports the development and expression of other athletic qualities. The amount required, however, depends on the activity: a shot putter and a triathlete need different foundations.

Tsatsouline argues that endurance athletes can benefit from heavy, low-repetition strength training that primarily makes them stronger neurologically without adding much muscle. He says such training has improved racing performance in triathlon, marathon running and cycling. The excerpt supplies no study references, training schedules or effect sizes, so this remains his account of the evidence rather than a protocol readers can evaluate in detail.

His framework includes a stopping point for prioritizing strength. He describes the Soviet concept of a model athlete: sport-specific benchmarks for measures such as squatting, bench pressing and jumping that were associated with better odds of success. For noncompetitive exercisers, he proposes having a reserve of strength for the demands of life and mentions military or law-enforcement physical-training standards as possible reference points. He explicitly declines to impose one universal set of standards. Once strength is adequate for a person’s sport or lifestyle, he favors maintaining it efficiently while developing other qualities.

The clearest illustration comes from research he attributes to Soviet scientists Verkhoshansky and Denisenko. Across athletes of different levels in 20 sports, they assessed absolute strength, rate of force development and the speed of muscular relaxation after contraction. According to Tsatsouline, strength increased only slightly between intermediate and advanced athletes, power increased somewhat more, and relaxation speed increased dramatically. In his interpretation, strength establishes a foundation, but further athletic advancement can depend more heavily on other capacities. The excerpt provides neither the underlying measurements nor enough methodological detail to establish why those differences occurred.

Tsatsouline’s exercise-selection principle is to concentrate on very few movements. At StrongFirst, he says, the aim is to offer simple approaches using whichever tools suit the individual: barbells, kettlebells, body weight or other equipment. He rejects the idea that one particular exercise is indispensable. Within that flexibility, he gives posterior-chain work a central role and says mobility and symmetry should be addressed first, pointing to Gray Cook’s work without developing that assessment process here.

For a barbell example, he starts with the narrow sumo deadlift. Narrow refers to the stance rather than the grip: the feet are far enough apart to let parallel arms pass between the legs. He emphasizes finding a comfortable stance that suits individual hip anatomy, referring to Stuart McGill’s earlier discussion with Huberman. He cites powerlifter Ed Coan as an example of this stance and distinguishes it from the wide sumo position used in sport-specific lifting.

The underlying skill is the hip hinge. Tsatsouline connects it to lifting an ordinary heavy object, such as a bag of groceries, and contrasts that demand with balance-ball routines that he does not see reflected in everyday life. He attributes the importance of hinging for back health and longevity to McGill. Learning the movement does not, in his account, require pursuing a very heavy deadlift: individual suitability and access to coaching can justify choosing another exercise.

His alternative is the Zercher squat, with the bar cradled in the crooks of the elbows in front of the body. He describes it as relatively easy to coach and particularly effective at eliciting reflexive stabilization of the midsection. He also presents it as an option for people whose shoulder, wrist or elbow problems make other squat positions difficult, although that is his broad assessment rather than an individualized medical judgment. Taking the bar from a rack is his preferred starting approach; lifting it from the floor is an advanced skill. He stresses proper coaching, comfortable positioning and avoiding bruising. Double body weight is offered as a possible goal for an athlete, not a universal starting requirement.

For pressing, Tsatsouline defends the bench press against its reputation as an exercise overemphasized by gym enthusiasts. His argument depends on the rest of the program: athletes who also train the lower body, posterior chain and midsection can make good use of it. He describes the bench press as relatively simple and unusually compatible with low training volume, saying that several sets of five once a week can continue producing strength gains. He contrasts this with the overhead press and one-arm pushup, which he suggests are less forgiving of such a sparse schedule. No comparative data or limits on how long those gains continue are supplied.

The broader selection criterion is transfer: an exercise should develop strength that extends beyond getting better at that exercise alone. Tsatsouline contrasts pull-oriented and compound options with curls, which he says mostly improve curling. He also cites work by Canadian researcher Doug McNeill and colleagues in the 1980s, saying that leg extensions did not transfer to the squat because the coordination demands differed substantially. His point is that strengthening a muscle in one task does not automatically reproduce the skill and coordination of another.

This preference for transfer leads to consistency rather than constant exercise changes. His practical selection criteria are enjoyment, pain-free execution, available equipment and proper coaching. Small variations—such as changing bench-press grip width or adding a squat pause—remain possible. He acknowledges arguments for variety, including neuroplasticity and a lower risk of repetitive strain injury, but says weightlifting statistics show no correlation between the number of exercises used and competition results. He extends that conclusion to nonathletes, although the excerpt supplies no separate evidence for that extension.

Huberman proposes a weekly combination of a squat, posterior-chain work such as kettlebell swings, pull-ups and dips. Tsatsouline agrees that this could be comprehensive. Huberman’s interest is partly efficiency and partly gaining strength and endurance without excessive size, though he allows that someone might want growth in selected body parts. His difficulty with dips is how to load them once body-weight sets exceed 15–20 repetitions. Tsatsouline responds with a remark attributed to powerlifter Luke Adams that anything above six repetitions is bodybuilding. In this exchange, the remark functions as a perspective on training emphasis; they do not establish six repetitions as a physiological dividing line or resolve Huberman’s loading question.

Tsatsouline’s endorsement of dips is conditional. They are excellent, he says, if a person’s shoulders tolerate them and the person knows how to perform them, but they are not accessible to everyone. He proposes developing a full skin the cat as a prerequisite for coaching the dip: entering the inverted hanging position and leaving it strongly and confidently. Even then, he says there is a good chance the person can begin learning dips, rather than offering a guarantee. He explicitly preserves the qualification that medical restrictions may rule out working toward that prerequisite.

Tsatsouline is broadly enthusiastic about pull-ups as a general strength exercise. He distinguishes sport-specific strength from general strength intended to transfer across activities, placing pull-ups and suitable dips in the latter category. Later he does explain how to combine strength and endurance work: when strength is the priority, he proposes no more than two strength-aerobics sessions alongside three or four strength sessions; when repeated strength endurance is the priority, he reverses the emphasis. He presents these as examples dependent on priorities and other training, not a single universal plan.

Huberman introduces grip strength with a domestic challenge: a 500-pound squat or 600-pound deadlift does not settle whether someone can open a pickle jar. Tsatsouline develops the point through irradiation, his term for tension spreading from a hard grip into other muscles. He argues that squeezing more forcefully can immediately improve performance elsewhere. His example is a strict curl set: after reaching the usual repetition limit, crushing the bar or dumbbell harder may permit several additional repetitions. This is presented as a demonstration listeners could recognize, not as a quantified experiment in the excerpt.

Tsatsouline also mentions the association between grip strength and longevity, but explicitly separates correlation from causation. He says they do not know why the association exists or whether making the grip stronger would extend life. His enthusiasm for grip training therefore should not be read as evidence of a demonstrated longevity intervention.

He describes two routes to developing grip: training it within another movement or working on it directly. For the first route, he suggests rope climbing or pull-ups, including weighted pull-ups, performed on a rope. His example schedule is rope climbing once a week and pull-ups a couple of days a week, without additional grip work. He also highlights the eccentric loading involved when a heavy kettlebell descends from overhead during a snatch. These examples concern what he calls crushing grip—the ability to squeeze—which he considers particularly useful to athletes and nonathletes. He acknowledges other grip categories without detailing them.

This distinction creates a small disagreement with Huberman’s expectations. Huberman had added farmer’s carries to improve his grip; Tsatsouline says carries and hanging from a bar can be beneficial while doing relatively little for crushing grip specifically. He also attributes to McGill the concern that carrying two heavy objects can heavily load the spine, then says asymmetrical carrying appears beneficial. He does not supply comparative loads, outcome measures or injury data here, so the exchange supports a distinction between training purposes rather than a general verdict on all loaded carries.

Tsatsouline then changes subjects from grip development to loaded endurance work. He describes the kettlebell mile, a protocol and test developed by Dr. Mike Prevost, whom he says previously worked with the US Marine Corps and Navy. The task is to run a mile carrying a kettlebell approximately 30% of body weight, switching hands as often as desired. He attributes the load choice to preserving gait: a heavier implement, he says, can cause the person to shift the hip sideways and change the movement.

The proposed benefits are better running posture, development of stabilizing muscles and improved ability to ruck, with less wear on the body than rucking itself. These are Tsatsouline’s claims; the excerpt contains no comparative testing. The conversation also makes clear that 30% is substantial: Huberman reports weighing 210 pounds, while Tsatsouline loosely mentions something like 62 pounds and then a 70-pound kettlebell. Those spoken estimates do not establish a single precise load. Tsatsouline stresses that this is not an activity to jump into immediately.

The carry position is specifically suitcase-style, at one side, without deliberately crushing the handle. Tsatsouline explicitly says that this version is not grip-development work. Frequent hand changes are central to his explanation: they interrupt sustained isometric contractions in the quadratus lumborum and other stabilizers. He characterizes the brief contraction-and-relaxation cycles as a form of anti-glycolytic training that lets the muscles keep working aerobically. That proposed mechanism is not demonstrated with measurements here. His progression is to begin by walking, switch hands often and gradually build toward running; the stated target is a mile, not a prescribed 10-, 20- or 30-minute session.

Huberman contrasts this with an experience on Cam Haynes’s podcast: carrying a 72-pound rock through the Oregon wilderness over about 1,000 feet of elevation gain. The awkward shape required shifting it between a shoulder, a football-style carry and an infant-style hold. Tsatsouline confirms that the kettlebell protocol is different. The comparison helps specify the task: a repeatedly switched suitcase carry rather than an awkward object moved among several positions.

Returning to direct grip work, Tsatsouline recommends IronMind’s Captains of Crush grippers and recounts training with StrongFirst colleague Brad Jones. After many months, both could close the number three gripper from a parallel set. He describes that gripper as requiring 280 pounds to close; the account preserves the parallel-set condition rather than describing an unspecified close. He reports that he, Jones and others felt many other tasks become easier after developing this level of grip, but provides no formal before-and-after performance data.

The striking part of his account is the effort required. Serious gripper work, he says, is a whole-body exertion rather than an isolated squeeze performed casually while driving. He compares the organization of tension to karate’s Sanchin stance: knees drawn inward, shoulders down, toes gripping the ground, glutes contracted, trunk firmly braced and the lat engaged. He describes directing that effort into the hand while trying to keep the face and trapezius muscles out of it. The fatigue, in his experience, can resemble that of heavy squats. Huberman responds by emphasizing the extent of motor-neuron recruitment being described.

Across these examples, strength is treated as a practiced capacity involving coordination and tension management. Later the promised family examples are developed: Tsatsouline says his 87-year-old father no longer deadlifts because of an old injury but still accumulates over 50 pull-ups twice weekly, while his mother uses a stair routine. His father-in-law reportedly progressed from a maximum of 10 pull-ups at 64 to 20 after months of submaximal practice. These individual accounts include long prior training histories and limitations; they do not establish age-specific outcomes for everyone.

The interview includes a sponsor break with claims separate from Tsatsouline’s training discussion. Promoting Eight Sleep, Huberman says body temperature needs to fall about one to three degrees for sleep and rise about one to three degrees for waking; no temperature scale is specified. He describes nearly four years of using the mattress cover, personally improved sleep, and the Pod 4 Ultra’s heating, cooling and snoring-response features. The offer is up to $350 off at eightsleep.com/huberman, with shipping described for the USA, Canada, UK, selected EU countries and Australia. These statements appear as advertising and personal testimony, with no supporting studies supplied in the excerpt.

In the Levels promotion, Huberman describes using continuous glucose monitoring for about three years to understand his responses to foods and to organize eating around exercise and sleep. He presents stable blood glucose as relevant to energy, focus and short- and long-term health, and says the feedback influenced his entire schedule. The advertised offer at levels.link/huberman is a newer, smaller sensor described as offering better tracking, plus two additional free months of membership. This passage supplies his experience and the sponsor’s product claims, rather than comparative evidence that the service improves health outcomes.

Andrew Huberman connects peripheral strength training with a proposed neurological dimension of aging. He describes motor neurons controlling the torso as lying nearer the spinal cord’s midline, with neurons controlling progressively more distal muscles positioned farther outward. He says age-related motor-neuron degeneration proceeds from outside inward even in the absence of ALS, Alzheimer’s disease, Parkinson’s disease, or another such condition. The explanation remains uncertain in his account: he suggests a possible relationship with the enzyme superoxide dismutase, or SOD.

Huberman explicitly distinguishes his interpretation from established causation. He believes training peripheral strength may offset some of this degeneration, rather than merely correlate with better preservation, but calls that causal interpretation a belief. He also mentions the brain’s movement maps without developing the explanation. His practical observation is that people aged 70, 80, or 90 can retain a thick, muscular torso while showing substantial calf atrophy. For him, this supports giving peripheral muscles attention alongside the core and torso when considering longevity; the excerpt does not establish that such training prevents neurological disease.

Pavel Tsatsouline agrees that there are many reasons to train peripheral strength. He presents direct work with grippers or other devices and exercises as one route, and integrated activities such as rope climbing as another. He strongly encourages this training without requiring a particular device.

A concrete correction follows when Huberman proposes running a mile with a kettlebell on his right side before changing sides. Tsatsouline immediately tells him to switch repeatedly instead. Holding the load on one side for that long, he argues, would heavily tax the stabilizers and prolong recovery. He links frequent switching to isometric endurance: repeated short contractions separated by brief rests. His explanation is that these interruptions help the muscle avoid ischemia and continue receiving oxygen.

Huberman next asks how the concentric and eccentric portions of a movement affect soreness, recovery, and training frequency. He identifies these broadly as the lifting and lowering phases. Tsatsouline’s case for concentric-only work begins with athletes seeking strength while minimizing muscle growth and soreness, particularly those in weight classes or sports where additional body weight carries a cost.

Tsatsouline illustrates this with Barry Ross’s coaching of Allyson Felix. In his account, Ross had Felix perform deadlifts and drop the bar, removing the loaded lowering phase. Tsatsouline recalls her winning the world 200 meters and thinks she was 17 and the youngest winner at that point. He presents the training choice as a way to gain strength without additional muscle mass and describes it as very safe. This is a coaching example in the discussion, rather than a controlled comparison demonstrating the separate contribution of concentric-only training.

He also sees a place for omitting eccentrics in programs without weight-class constraints. Certain days could use this variation to support recovery: lift the weight, then step down instead of performing the corresponding loaded lowering phase. Although he says eccentric work is supposedly helpful for hypertrophy, he immediately qualifies that statement as having many complications and turns his attention specifically to strength.

For strength-focused eccentrics, Tsatsouline’s starting concern is that muscles can handle more load while lowering, making reckless overload easy. His proposed bench-press example requires competent spotting. After the usual couple of heavy, low-repetition sets, the lifter adds perhaps 5 or 10 pounds above the maximum, lowers with precise control and the intention of pressing, then pauses on the chest without losing tension. The spotters remove the bar. He describes doing this about two or three times.

Tsatsouline cites Rick Will as having used this strategy or a variation, including with heavy attempts. He credits Will with bench-pressing more than 500 pounds in a T-shirt during the 1980s at a body weight of about 81; the supplied passage does not specify the unit for that body-weight figure. The example illustrates Tsatsouline’s respect for carefully planned overload, but does not by itself establish the method’s effectiveness or safety for other lifters.

Tsatsouline describes a related assisted-repetition method, then corrects himself to specify that it belongs on a different day rather than simply being a better version of the preceding exercise. For someone whose best bench press is 315, his example uses 325. The lifter lowers at the rhythm of a maximal attempt, pauses, and presses while a partner supplies enough assistance to make the effort feel like roughly 90%. He rejects the pattern of lowering extremely slowly through the first quarter of the range and then collapsing through the remainder.

The distinction he draws is between precise assistance and a desperate forced repetition. The purpose is to experience a supramaximal load while preserving good execution and avoiding psychological stress. He suggests perhaps one or two singles. The extra load is therefore paired with assistance sufficient to keep the movement manageable, rather than an expectation that the lifter complete an unaided repetition beyond the current maximum.

He connects this approach to Soviet gymnastics research on what he calls an artificial controlling environment. One group reportedly combined conventional skill regressions with strength exercises such as weighted pull-ups. Another received carefully calibrated coaching assistance to perform the demanding skill at a higher level, with enough help to make it difficult but not stressful. Tsatsouline reports substantially faster and larger gains in the assisted group. The passage supplies no sample sizes, numerical results, or study details, so the comparison remains a reported research example rather than an independently assessable result here.

Tsatsouline gives isometrics a role beyond strengthening a difficult point in a lift: they can teach positioning. His martial-arts example places a learner’s foot against a wall while a coach adjusts the body and foot. The learner applies pressure into both the wall and ground, pulses against the wall, makes adjustments, then relaxes, shakes out the muscles, and tries the kick on a bag. The fixed contact is meant to make useful force production easier to identify before returning to movement.

His deadlift example uses a load too heavy to lift. The athlete wedges into the starting position, applies pressure, and changes the setup when it feels wrong. Tsatsouline presents this as a way to optimize angles as well as address sticking points. In both examples, the stationary effort provides an opportunity to explore alignment without having to complete the full movement.

He also describes strength through the interaction of excitation and inhibition, comparing them to a gas pedal and a brake. Psychological and other influences can inhibit force production. To illustrate disinhibition, he invokes what he describes as documented cases of a woman lifting the front of a 3,600-pound car to save her son. The figure refers to the car’s weight; he does not say she lifted the whole vehicle. He argues that isometrics can have disinhibitory effects, although the excerpt supplies no measurements of those effects.

Another proposed benefit is persistence when a heavy attempt slows. Tsatsouline describes safely conducted machine experiments in which inexperienced participants tended to give up as movement speed approached zero. He interprets isometric training as developing the endurance of neural drive needed to keep working through a slow attempt safely. For incorporating isometrics, he mentions warm-ups and paused repetitions. His squat example combines all three contraction types: lower to parallel, maintain tension for three to five seconds, then accelerate upward.
