Hypertrophy Past and Present

In this episode of Hypertrophy Past & Present, Jake and Chris begin by reviewing Stuart McRobert’s 1989 hardgainer routine, a minimalist two-day-per-week program designed as an alternative to the increasingly extreme bodybuilding routines of the late 1980s. The conversation then explores an important distinction: is every period of stalled progress really a plateau, or are there times when we should simply expect progress to slow or stop?

Key topics include:

In this episode of Hypertrophy Past & Present, Jake and Chris begin with another Leroy Colbert routine, this time examining an over 100 set silver-era routine. The conversation then explores whether you actually need to “feel” a muscle for it to grow, what the pump can tell us about muscle recruitment, and where the mind-muscle connection may or may not be useful.

Key topics include:

In this episode of Hypertrophy Past & Present, Jake and Chris begin with Leroy Colbert’s late-1970s enormous volume training plan. The conversation then explores whether using pre-steroid bodybuilders as a model for natural training is really an “appeal to tradition,” before examining the evidence that anabolic steroids can directly stimulate muscle growth even without resistance training.

Key topics include:

In this episode of Hypertrophy Past & Present, Jake and Chris begin with Reg Park’s 1949 pre-contest routine, which involved training six days per week, twice per day, including the infamous 20-rep breathing squat. This leads into a deep dive on time under tension: Does making a set last longer actually increase muscle growth? Jake and Chris explore why total time under tension may be the wrong thing to measure and whether we should instead be thinking about “time under stimulating tension.”

Key topics include:

In this episode of Hypertrophy Past & Present, Jake and Chris begin with a full-body routine from legendary bodybuilding coach Vince Gironda and the unusual reliance on isolation exercises. The conversation then shifts to workout duration: Is there any truth to the claim that workouts must be kept under 45, 60 or 90 minutes? Jake and Chris examine what actually happens as a workout becomes longer, including declining motivation, cardiovascular fatigue, exercise-order effects, cortisol, and the post-workout MPS elevation.

Key topics include:

In this episode of Hypertrophy Past & Present, Jake and Chris begin with an early 1950s “muscular bulk” routine from Jack Delinger. They discuss the minimalist, barbell-only full-body program and how exercise variety may need to gradually increase as a bodybuilder becomes more advanced.

The conversation then shifts to training plateaus: what actually qualifies as a plateau, why slow progress is often mistaken for no progress, and how to distinguish between plateaus caused by accumulating fatigue and those caused by limitations in exercise selection or motor unit recruitment.

Key topics include:

In this episode of Hypertrophy Past & Present, Jake and Chris begin with a 1972 routine from Bradley J. Steiner and discuss what makes it one of the more sensible "golden era" bodybuilding programs they've reviewed so far and whether splitting exercises across consecutive days is likely to be more or less effective than performing all exercises in a single workout. 

The conversation then shifts towards the concept of "training hard." Jake and Chris unpack what hard training actually means, why RPE is often a poor proxy for hypertrophy, and how chasing "hard training" can unintentionally encourage fatigue instead o...

In this episode of Hypertrophy Past & Present, Jake and Chris begin with Steve Michalik’s enormous 1972 Mr. America routine and why silver-era routines are the best data set for natural training routines. From there, Jake and Chris explore how the hypertrophy dose-response relationship interacts with the stimulating reps model. They discuss why the second and third sets provide progressively less growth stimulus, whether this means they contain fewer stimulating repetitions, and how the answer depends on whether the reduction is caused by fatigue or stimulus saturation.

Key topics include:
• Steve Michalik’s 1972 Mr. America routine
• How trai...

In this episode of Hypertrophy Past & Present, Jake and Chris begin with Alan Stephan’s classic Silver Era full-body routine, which he reportedly followed for years while building enormous strength and muscle. This leads into a deeper discussion about exercise variation, whether exercises really “stop working”, and why good natural bodybuilding programs often end up looking repetitive.

From there, Jake and Chris move into one of the most important physiological arguments behind the stimulating reps model: hypertrophy is not a whole-muscle phenomenon, but a muscle-fibre-specific one. They discuss why this matters for understanding mechanical tension, light-load training to fai...

In this episode of Hypertrophy Past & Present, Jake and Chris begin with a classic Clancy Ross full-body routine from the Silver Era, then move into a discussion about training frequency, mTOR, muscle protein synthesis, and whether training again before the previous hypertrophy stimulus has “finished” is actually a problem.

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:

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:

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:

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 p...

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 topi...

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 ex...

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.

From there, the episode pivots into the two main problems coaches have to solve today: time constraints and novelty expectations, plus practi...

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

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:

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.

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<...

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.
