Hypertrophy Past and Present

In this episode of Hypertrophy Past & Present, Jake and Chris break down an often misunderstood programming question: how does full body training twice per week compare to an upper/lower split performed four times per week? The episode begins with a deep dive into a late 1960s program from Chuck Sipes, before discussing the key differences between full body and upper/lower when frequency is equated.Key topics include: • Why full body twice per week is one of the most underrated training splits • A breakdown of a classic Chuck Sipes program • The difference between within-session fatigue vs post-workout fatigue • Why back-to-back training days may reduce motor unit recruitment • Why doing more volume per session can actually limit long-term progress • The trade-off between rate of growth vs ceiling of growth • Practical considerations (time, lifestyle, gym access) that influence split selection

In this episode of Hypertrophy Past & Present, Jake and Chris break down how to structure a training program during a dieting phase. The episode begins with a deep dive into how Silver Era bodybuilders approached “definition” training, including a reconstructed Reg Park program, before moving into the physiological realities of training in a calorie deficit.Key topics include:• Why Silver Era bodybuilders didn’t drastically change their training when dieting • Reg Park’s “definition” routine • Why exercise variety may help prevent atrophy during a calorie deficit • Why high volume and excessive fatigue are counterproductive when cutting • How to adjust reps, load, and exercise selection based on equipment and fatigue • Practical programming strategies • Why most modern “evidence-based” takes on programming miss key physiological details

In this episode of Hypertrophy Past & Present, Jake and Chris discuss how to build the biggest glutes possible. The episode begins with a rare Silver Era lower-body routine from a female 1940s strength athlete Abby “Pudgy” Stockton, before breaking down the most effective modern exercises for glute development.Key topics include: • Abby Stockton’s 1940s lower body routine • The difference between upper and lower regions of the gluteus maximus • Why seated hip abduction is one of the best exercises for the upper glutes • Hip thrust vs glute bridge • Why squats and leg presses can still stimulate glute growth in the stretched position • Why glutes can often tolerate more training volume than upper body muscles • A simple three exercise framework for maximizing glute development

In this episode of Hypertrophy Past & Present, Jake and Chris discuss how to build the biggest arms possible. The episode begins with a Golden Era arm routine from Chuck Sipes, before assessing the best exercises for both minimalist and maximalist arm programming.Key topics include:Chuck Sipes’ Golden Era arm routine (biceps and triceps)How different exercises bias the brachialis, brachioradialis, and biceps brachiiWhy chin-ups are not actually a great biceps exerciseVoluntary activation deficits and why exercise variety mattersThe difference between minimalist and maximalist programmingWhy arm muscles fatigue and damage more easily than most people think

In this episode of Hypertrophy Past & Present, Jake and Chris dive into whether more volume is always better. The episode opens in the late Silver Era with Sergio Oliva’s high-volume split, then pivots into a brand-new study that compares “high” vs “super high” volumes in trained lifters. Key topics include:Sergio Oliva’s late-Silver Era routine New study 18 vs ~32 sets per weekWhy “more volume” didn’t produce more hypertrophyDamage as “resource drain” vs damage as fatigueNo fascicle length changes in trained lifters (and what that implies about sarcomerogenesis)Practical programming tip, reframing “rest days” as repair days

In this episode of Hypertrophy Past & Present, Jake and Chris unpack a new hypertrophy study that illustrates how fatigue doesn’t just make training harder but can directly reduce the hypertrophic stimulus by lowering single-fibre mechanical tension. The episode opens in the Silver Era again with Henry Paschal’s 1950 “busy person” program then pivots into the core discussion: why fatigue mechanisms (CNS and calcium-ion related) dampen muscle growth, and what this implies for exercise order, rep ranges, and advanced training methods. Key topics include:Henry Paschal’s 1950 routineA new “repetition duration” studyHow CNS fatigue and calcium-ion fatigue both serve the same functionWhy max effort and slow velocity don’t always equal max recruitment and max tensionProgramming implications: exercise order, rep ranges, RIR, clusters, and isometrics

In this episode of Hypertrophy Past & Present, Jake and Chris break down how you can become stronger immediately - not by changing your program, but by changing your motivation. The conversation starts in the Silver Era again, comparing Clarence Ross’ 1949/50 routine to his 1952 “favourite routine”, and why the small adjustments he made make physiological sense. From there, Chris connects motivation to motor unit recruitment through Marcora’s Psychobiological Model of Fatigue.Key topics include:Clarence Ross’ 1949/50 vs 1952 routine: what changed and why it mattersHow motivation can increase strength right now via higher voluntary activation / recruitmentPractical ways to boost motivationHow cognitive fatigue reduces performance and how to mitigate it in the gymWhether or not you can “stack” motivation tools

In this episode of Hypertrophy Past & Present, Jake and Chris unpack periodisation for hypertrophy, including what it actually is (and isn’t), why most “periodised” bodybuilding programs end up adding complexity without adding results, and which variables you can change over time without accidentally driving atrophy or accumulating a fatigue debt. The episode opens in 1952 with Clarence Ross’ pre-steroid full-body AAA “favourite routine”. From there, Jake and Chris break down the three main variables people try to periodise in hypertrophy training: volume, rep range, and exercise selection. Key topics include:-Why Clarence Ross’ 1952 full-body plan is a great 'non periodised' template-What is training 'periodisation'-The 3 variables people periodise for hypertrophy: volume, rep range, exercise selection-Why escalating volume blocks can reduce stimulus-Why light-load blocks for 'capillarisation' doesn't potentiate future hypertrophy-The only phase potentiation effect that really makes sense for hypertrophy

In this episode of Hypertrophy Past & Present, Jake and Chris tackle a surprisingly common question: what if you can only train once per week? Beginning with an early-1960s two-way split from John McCallum to discuss exercise sequencing, why multi-joint lifts paired with single-joint “finishers” can preserve recruitment better than simply adding more straight sets, and what older routines got right (and missed) due to equipment constraints. The episode then breaks down why once-weekly training is uniquely difficult for hypertrophy, how maintenance literature informs minimum set targets, and what a realistic once-per-week template actually looks like.Key topics include:-John McCallum's silver era two-way split and how we would modify it today-Why very high reps don't cause the same muscle growth as moderate reps-Training once per week: when it’s a real constraint vs avoidable-Why every 5 days is a massive upgrade over every 7-Different once per week program ideas-Posing as a mid-week stimulus

In this episode of Hypertrophy Past & Present, Jake and Chris analyse one of Dorian Yates’ early pre-Olympia training programs, breaking down the structure of his torso-limbs split and the intuitive exercise sequencing.From there, the conversation expands into a deeper discussion on exercise selection within a workout, why multiple exercises for the same muscle in a single session can produce a superior stimulus to rotating single exercises across sessions, and how this ties into neuromechanical matching and motor unit recruitment. The episode finishes with Chris addressing common criticisms of neuromechanical matching, explaining why alternative theories fail to explain motor control, efficiency-driven muscle recruitment, and sarcomere adaptation during strength training.Key topics include:Dorian Yates’ early torso-limbs programWhy single-joint “finisher” exercises maintain recruitment levels better than extra setsPractical improvements to Dorian’s plan using modern biomechanicsThe physiological problem with ABC exercise splits for hypertrophyHow to structure multi-exercise workouts without increasing gym timeNeuromechanical matching explained simplyWhy leverage must govern muscle recruitmentWhy active length-tension theories fail as motor control models

In this episode of Hypertrophy Past & Present, Jake and Chris break down the resurgence of “advanced” training techniques like clusters, supersets, giant sets, pre-exhaust, drop sets, and rest-pause. Using an early Chuck Sipes “heavy-light” split as an example of early bodybuilding plans that incorporated some advanced methods, the conversation then explains why most of these methods are at best time-saving rather than stimulus enhancing. The episode finishes with Jake and Chris discussing a “physiological drop set” concept, which may increase recruitment levels without suffering from the same fatigue problems as other advanced methods. Key topics include: -Chuck Sipes’ early “heavy-light” superset program -Why most supersets (agonist or antagonist) reduce stimulus rather than increase it -Why pre-exhaustion methods don't work -Why classic drop sets tend to be the worst “advanced technique” -Rest-pause vs clusters -A “physiological drop set” idea

In this episode of Hypertrophy Past & Present, Jake and Chris analyse a Golden Era training plan attributed to Larry Scott and Vince Gironda, using it as a lens to explore how hypertrophy programming evolved after the introduction of anabolic drugs. From there, the conversation pivots into a deeper examination of modern debates around exercise selection, “redundant” movements, single vs multi joint training, and the current discussions around form. Chris introduces voluntary activation deficits as the unifying physiological principle.Key topics include:Larry Scott’s Golden Era full-body routineThe limits of motor unit recruitment and voluntary activation deficits"Redundant" exercisesWhy more total muscle mass in an exercise reduces local recruitmentThe form debate and how excessive technique focus can impair hypertrophy outcomes

In this episode of Hypertrophy Past & Present, Jake and Chris kick off 2026 with a Part 2 follow-up aimed at coaches. Last episode was about the mistakes lifters make when they return to the gym, this week is about the mistakes coaches make when they design and deliver programs to clients. The conversation starts with Bob Hoffman’s time-efficient “working man” full-body routine and why the plan made sense for its context, while also pointing out where it falls short. From there, the episode pivots into the two main problems coaches have to solve today: time constraints and novelty expectations, plus practical strategies that can be used to solve these problems and deliver effective sessions. Key topics include: -Bob Hoffman’s minimalist full-body routine for busy lifters -Simple exercise swaps that improve full-body development with limited equipment -The two constraints coaches must solve: novelty and time -How to give the illusion of novelty without compromising programming efficacy -Time efficiency: avoiding cardiovascular-limited sets, smarter exercise order, and exercise structuring -Using rest periods to add value instead of feeling like dead time -A better approach to 30-minute PT sessions

In this episode of Hypertrophy Past & Present, Jake and Chris take a practical, end-of-year look at the most common mistakes people make when returning to the gym, whether they’re starting fresh in January or jumping back in after time off. Using a pre-steroid era full-body routine attributed to George Eiferman the discussion highlights what earlier bodybuilders consistently got right.From there, the conversation expands into current gym programming trends, including unstable exercise selection, cardio-driven exercises, excercise novelty, poor progress tracking, and misguided injury-prevention strategies. Key topics include:-George Eiferman's "favourite" 1952 full-body routine-Why unstable exercises reduce motor unit recruitment-The problem with excessive cardiovascular demand-Why changing exercises too often prevents meaningful hypertrophy-Progressive overload as a tracking tool-Muscle damage, repeated bout effect, and the risks of rushing back after time off-Why warm-up sets aren't the same as 'warming up'

In this episode of Hypertrophy Past & Present, Jake and Chris break down Mike Mentzer’s “most productive” routine and use it as a turning point to discuss how training trends shifted across the Golden Era. From there, the conversation shifts to how anabolic steroid use increases tendon and ligament rupture risk and whether the rise of higher-rep training, shorter rest periods, machines, slower eccentrics, and lower frequency in the post-steroid bodybuilding era might partly reflect an unconscious attempt to manage connective tissue risk as drug use escalated.Key topics include:Mike Mentzer’s two-way split (with rest days) and why it’s more “physiology-friendly” than most people expectThe tendon problem with anabolics: collagen synthesis, collagen breakdown, and possible disorganised tendon structureHeavy vs light loads in enhanced liftersBFR as a tool to reduce injury risk in enhanced liftersPractical programming to reduce injury risk

In this episode of Hypertrophy Past & Present, Jake and Chris shift from the Silver Era into the early anabolic era by analysing a Golden Era training plan from Ken Waller. Using Waller’s 1975 routine as a case study, they explore how bodybuilding training changed as anabolic use became more common. The discussion then transitions into a deep dive on the Weekly Net Stimulus model and why hypertrophy must be understood at the muscle fibre level.Key topics include:Ken Waller’s 1975 Golden Era training split and how it contrasts with Silver Era full-body plansWhy large volumes can appear “unrecoverable” on paper but may differ in practiceVoluntary activation deficits and why muscles cannot be fully activatedMuscle fibre–specific hypertrophyThe Weekly Net Stimulus model: assumptions, limits, and what it can (and can’t) tell usThe role of practical compromises, adherence, and time constraints in real-world programming

In this episode of Hypertrophy Past & Present, Jake and Chris revisit the Silver Era through one of the most iconic Silver Era bodybuilders, John Grimek, and his bulking plan. They then discuss what muscle protein synthesis (MPS) and muscle protein breakdown (MPB) really mean, dismantling the idea that “elevated MPS = muscle growth”. Key topics include:-John Grimek’s full-body gaining routine and the practical logic of Silver Era plans-MPS vs MPB and net protein balance-Why you can’t assume elevated MPS always reflects hypertrophy or protection from atrophy-How steroids physiologically make dieting and comp prep "easier"

In this episode of Hypertrophy Past & Present, Jake and Chris go back to 1945 and break down Clancy Ross’ pre-contest “definition” routine to show how Silver Era lifters tried to get lean using their gym programming. From there they pivot into dieting and how caloric restriction, stress, glycogen, and glucocorticoids actually affect muscle protein synthesis and muscle protein breakdown. Key topics include:Clancy Ross’ 1945 full-body “reducing routine” and why even this questionable plan still beats most modern fat-loss programsA muscle-physiology model of dieting: suppressed MPS and when deficits become a stressor that ramps up muscle protein breakdownWhy anabolics (and even TRT) largely sidestep these dieting problemsPractical tips for naturals: adjusting training volume, keeping frequency high, pre-workout carbs, carb mouth-rinse, post-workout protein, and subjective stress load

In this episode of Hypertrophy: Past & Present, Jake and Chris use a 1967 Bill Pearl program to jump from the silver era into the early steroid era, showing how training volume exploded once anabolics entered the picture. They contrast Bill Pearl’s high-volume, six-day split and contrast it with his earlier natural-era programming, before diving into a new study comparing heavy versus light loads in trained lifters and what it really means for stimulating reps, volume load, and rep range choices.Key topics include:Bill Pearl’s 1967 high-volume, six-day split and how it differs from his natural-era routinesHow anabolic steroids break the feedback loop and drive the shift toward extreme training volumesA new heavy vs light load study in trained liftersWhat this means for the stimulating reps model, volume load, and rep ranges for natural vs enhanced lifters

In this episode of Hypertrophy: Past & Present, Jake and Chris dive into a Bill Pearl full-body routine, using it as a bridge between the pre-steroid silver era and the early anabolic era. From there, they shift into part two of their sleep series, unpacking how sleep loss influences muscle atrophy and recovery in natural lifters.Key topics include:Bill Pearl’s 1957 full-body planThe difference between immobilisation/diet-induced atrophy vs stress/sleep-loss-induced atrophy Practical programming changes when sleep is poorWhy dieting hard while sleep-deprived is a recipe for muscle loss in naturals, and why enhanced lifters often don’t experience the same downside

In this episode of Hypertrophy: Past & Present, Jake and Chris break down Bob Hoffman’s basic athletic program through a modern physiology lens and unpack how insufficient sleep impacts training performance.Key topics include:Bob Hoffman’s silver era full-body athlete hypertrophy programSleep deprivation vs restriction vs cumulative sleep debtHow insufficient sleep affects hypertrophy training performancePractical strategies for adjusting a workout after poor sleep

In this episode of Hypertrophy: Past & Present, Jake and Chris discuss Silver-Era author Peary Rader’s “training as you get older” guidelines and dive into how to construct a modern, physiology-led template for older lifters.Key topics include:Why recovery, not “low stimulus sensitivity” likely limits muscle growth in older liftersIntra-session fatigue control in older liftersProgramming for older lifters: volume, RIR, exercise selection, frequencyIsometrics for older lifters

In this episode of Hypertrophy: Past and Present, Jake and Chris unpack a Silver-Era routine passed from 1950 Mr America John Farbotnik to Gene Mozee at a time where high volume plans were taking over bodybuilding. From there they go deep into accumulating fatigue, how excitation–contraction coupling failure, muscle damage, and supraspinal CNS fatigue interact across sessions, why exercise novelty and split design can make this worse, and how to calculate and clear your “fatigue debt” without losing muscle.Key topics include:John Farbotnik full body routineBack-off sets: why back-offs add soreness but little stimulusThe three post-workout fatigue mechanisms (ECC failure, muscle damage, supraspinal CNS): timelines, interactions, and accumulationHow swapping exercises can re-hit damaged fibres and accumulate fatiguePractical programming, typical recovery times, and fatigue-debt math

In this episode of Hypertrophy: Past and Present, Jake and Chris unpack Steve Reeves’ 1947 pre-competition full-body routine, then dive into why the Silver-Era were such advocates of orange juice + honey during training. We assess the building research on carbohydrate mouth-rinsing, what this tells us about supraspinal CNS fatigue, and how the performance increase from carbohydrate mouth-rinsing differs from the performance increase from creatine supplementation. Key topics include:Steve Reeves’ 1947 pre-comp full-body planWhat carbohydrate mouth-rinsing is doing and intra-workout carbohydratesWhy everyone experiences supraspinal CNS fatigue during strength training and what you can do about itWhy creatine adds reps without adding stimulus, but carbs can add stimulating reps

In this episode of Hypertrophy: Past and Present, Jake and Chris break down Dick DuBois’ 1954 full-body routine (and we finally have some pull-ups!). They then tackle the “half-set” myth, why counting half sets for secondary muscles make any sense and how to adjust multi joint exercises to bias growth in a particular muscle.Key topics include:• Dick DuBois’ 1954 full-body plan• The “Half-Set” problem • Damage in secondary muscles• Using multi joint exercises in beginner vs advanced lifters

In this episode of Hypertrophy: Past and Present, Jake and Chris unpack Reg Park’s calf-specialisation phase before discussing the physiology of pauses: when they work, when they don’t, and how they compare to partial reps.Key topics include: • Reg Park’s 1952 calf-specialisation program • Straight-leg vs bent-leg calf work and how they bias gastroc vs soleus • The physiology of pause fatigue: metabolite vs calcium-related mechanisms • Why static “passive” stretching isn’t the same as active pause contractions • How to assess whether a given exercise will actually benefit from pauses

In this episode of Hypertrophy: Past and Present, Jake and Chris discuss Sig Klein’s extensive routine and use it as a springboard to tackle one of the biggest programming questions: how much exercise variety do you really need for maximal growth?Key topics include:How neuromechanical matching explains which motor units get recruited firstVoluntary activation deficits - why bigger muscles and bigger lifts mean some motor units aren't recruitedHow to use unilateral work to meaningfully increase recruitmentWhy some muscles require greater exercise variation than others

In this episode of Hypertrophy: Past and Present, Jake and Chris revisit Joe Weider’s early 1940 full-body program before breaking down the central problem that all split routines face: supraspinal CNS fatigue.Key topics include: • How calcium-ion–related fatigue and inflammation create global CNS fatigue • Why back-to-back training days reduce recruitment, even for unrelated muscles • Why full-body AAA and AB formats avoid these issues

In this episode of Hypertrophy: Past and Present, Jake and Chris explore Sig Klein’s early A/B full body routine from the pre-steroid bodybuilding era before examining the claim that elevated myofibrillar protein synthesis blunts the effectiveness of subsequent workouts.Key topics include:Sig Klein’s beginner routine The difference between myofibrillar protein synthesis and hypertrophy stimulusWhat comparing one vs three set studies shows us about elevated synthesis timelinesWhy any overlap effect is small (and irrelevant for single-set workouts)Why the weekly net stimulus still favours three times per week over two times per week training

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley dive into a 1955 arm specialization routine from Peary Rader and use it as a launchpad to challenge one of the most common misconceptions in hypertrophy programming today.They explore whether exercises can “bias” specific muscle regions, and what the implications are for hypertrophy programming.Key topics include:What it really means to “bias” a region of a muscleWhy the idea that a single exercise can train the whole muscle and “bias” a region is falseThe critical role of voluntary activation deficits and neuromechanical matchingPractical implications for programming, periodisation, and avoiding fibre-specific atrophy

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley unpack the very first York Barbell course, discussing its warm-up approach and how it compares to other silver era routines.The second half of the episode zooms out to explore warm-ups more broadly, what they actually do (and don’t do), whether they affect hypertrophy, and why most warm-up advice might be misguided.Key topics:The three physiological effects of warming up: temperature, PAP, and PAPEWhy most common warm-up routines may do nothing for hypertrophy or injury preventionHow to structure warm-ups that actually do something

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley break down a pre-steroid bulking routine from Alan Stephen, an underrated Silver Era bodybuilder who trained with a pretty unique method. They explore how this high volume, low rep program makes sense with the stimulating reps model, and use it as a springboard to unpack one of the most misunderstood training concepts: work capacity.Key Topics: • The three definitions of “work capacity” and which one actually matters • Why volume doesn’t improve your ability to do more work • How cardiovascular endurance (and not higher reps or more sets) influences gym performance

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley explore whether full body training can be done every day, and what that really looks like. Drawing inspiration from Bronze Era strongman George Hackenschmidt, they unpack creative strategies for making high frequency training work.Key Topics:How training every day differs from traditional 3x per week programmingHow MYOPS behaves and whether it must return to baseline before training againWhat programming variables to consider when training full body daily

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley return to Reg Park, but this time explore one of his most advanced programs.

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley discuss one of the strongest bodybuilders of the Silver Era, and the third man to ever bench 500 pounds, Marvin Eder's training routine. The second half of the episode takes a deep dive into the mechanisms of strength, why strength isn’t a single adaptation, and why hypertrophy does contribute to strength.Key Topics:The alignment between old-school programming and recoverability dataWhy strength isn’t one thingThe 6 mechanisms of strength gains (and how they interact)What lateral force transmission is

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley dissect Reg Park’s 1950s “Mr. Universe Bulk Course”. Unlike the high-variation, single-set approach of Steve Reeves discussed in the previous episdoe, Reg Park’s plan featured fewer exercises but high set volume, low reps, and heavy loads. The second half of the episode shifts into a deep dive on post-workout fatigue; what it actually is, what causes it, and why the common beliefs about fatigue and recovery might be wrong. Key topics:The surprising recoverability of low rep, high set trainingWhy post-workout fatigue is driven by calcium ion accumulationThe four types of post-workout fatigueWhy understanding the mechanisms of fatigue helps unlock more efficient programming

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley break down Steve Reeves’ favourite full-body routines from the early 1950s. They explore how Reeves trained each muscle with three different exercises, and why this multi-exercise, single-set approach might still be one of the most efficient ways to train if programmed correctly. The episode dives into the physiology behind exercise variation, the concept of neuromechanical matching, and how advanced lifters can apply full-body A/B splits to maximise hypertrophy.Key topics:The difference between single sets per muscle vs. per exerciseWhy muscle hypertrophy and atrophy are muscle fibre-specific (not muscle-specific)How neuromechanical matching determines which fibres get trained in each exerciseHow to program more efficiently to achieve more growth with less work

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley examine Clancy Ross’ 1940s split set routine - an early experiment in dividing upper and lower body training that predated modern training splits. They break down how Ross evolved his training by splitting full-body workouts into AM/PM upper/lower sessions and discuss what this teaches us about fatigue management, muscle damage, and cardiovascular recovery. Key topics:How Clancy Ross experimented with splitting his full body sessions into upper/lowerThe two types of supraspinal CNS fatigue (intra-workout vs. post-workout)How cardiovascular fitness governs your session capacityWhy some lifters respond better to either full-body 3x per week or upper/lower 6x per week

In this second episode, Jake Doleschal and Chris Beardsley break down the York Barbell Mr America Course, a program from 1951 that evolved from the earlier Milo Barbell plan. They explore what changed in the decades following the first mass-produced bodybuilding programs, including the introduction of sets, improved exercise selection, and targeted variations. They then connect these historical shifts to modern muscle physiology, focusing on how long the hypertrophy stimulus lasts after a workout, and why full-body training remains superior. Key topics: How the York Barbell Course built on the Milo planWhy the shift from reps to sets was a turning pointHow to interpret MPS/MYOPS data without confusing stimulus and damageWhy most hypertrophy occurs within 24–36 hours of a sessionHow this insight changes everything about training frequency
