Most bodybuilders waste money on the wrong garage gym setup because they build it like a general fitness space instead of around hypertrophy.

In this episode, we break down exactly how we’re designing our own bodybuilding garage gyms, what equipment matters most, how to choose the right centerpiece rack, and the biggest mistakes to avoid before buying anything. If you...

Retatrutide is getting a ton of attention in bodybuilding, but most people still do not understand where it actually fits. In this episode, we break down how it works, where it may help during contest prep or post-show, and where it can absolutely hurt performance, peak week accuracy, recovery, and muscle retention.

We also cover real-world dosing considerations, side effects, and why this is a tool for specific cases, not a shortc...

How often should you actually change your workout split — and is switching too soon killing your progress? In this episode, we break down the real science behind exercise rotation vs. repeatability, including what a 2021 study revealed about regional muscle growth and whether variety actually builds more muscle.

We cover how your experience level should dictate how often you rotate, which muscle groups genuinely need exercise varie...

If your lifts stop progressing, the worst mistake you can make is assuming you’re actually stalled.

In this episode, I walk through how I diagnose stalled training performance in physique athletes and why most plateaus are misidentified. I explain how recovery, fatigue, rep quality, split design, and exercise sequencing affect progression long before you need to change...

Most lifters aren’t limited by science — they’re limited by how hard they actually train.

In this episode, we break down what truly drives hypertrophy from a real coaching perspective — beyond theory and into practical application. I sit down with Steve Hall to discuss evidence-based training, proximity to failure, deloads, volume management, and how advanced athletes ...

The fastest way to stall your physique isn’t diet—it’s getting injured and losing training time.

In this episode, we break down the most common bodybuilding injury patterns (elbows, knees, low back, rotator cuff) and how to prevent them with better movement matching, exercise selection, and load management. We also explain how to spot the warning signs early, adjust ROM and resistance profiles, and when it’s time to stop “pushing” ...

Most lifters “maintain” after a bulk—and accidentally lose more progress than they realize.

In this episode, we break down what actually determines whether you keep muscle after a growth phase: training stimulus + recovery, not a magic maintenance block. We walk you through the assessment we use before the push ends, when to go straight into a fat loss phase, and when ...

If your week-to-week visuals suddenly tank, you’re not “still growing”—you’re stacking dieting debt.

In this episode, we break down the earliest signs your growth phase has stopped being productive—especially the visual shift that tells you fat gain is outpacing muscle. We also cover how prep timelines get ruined, which health/sleep markers matter most, and why “holding” (maintenance) is often the smarter move before the next push.

2025 was supposed to be the most science-driven era of hypertrophy training — but instead, much of the “science-based” conversation turned into rigid dogma. In this episode, John Jewett and Luke unpack what actually happened, why black-and-white rules took over the internet, and what lifters and coaches should carry forward into 2026 if the goal is maximal muscle growth.

They break down the biggest misapplications that domi...

If you could only pick one exercise per muscle group to maximize hypertrophy, what would you choose—and which “go-to” movements are actually overrated? In this episode of the J3 University Podcast, John Jewett and co-host Luke Miller continue the series (following last week’s upper-body breakdown) by covering lower body and arm training through a practical lens: biomechanics, repeatability, and long-term sustainability.

What’s the single best exercise for building muscle in each upper-body muscle group—and which popular movements are actually overrated? In this episode of the J3 University Podcast, John Jewett and co-host Luke Miller break down their top upper-body exercise picks using a clear, systems-based framework focused on stimulus quality, repeatability, and long-term sustainability.

They walk through what truly defines a “great” exercise, ...

Most fat loss advice is either overrated or misunderstood—and it can cost you weeks in a dieting phase or contest prep. In this episode, Luke and I break down common “fat loss hacks” and explain what actually moves the needle: adherence, a controlled deficit, protecting training performance, and managing fatigue. We also cover why fasted cardio and intermittent fasting aren’t magic, how to think about carbs and intra-workout nutrit...

You can train hard, eat perfectly, and still feel run down… if your sleep is off.

In this episode, Luke and I break down why sleep becomes such a common bottleneck for bodybuilders, what’s actually causing it (environment, stress load, stimulants, PED-related sympathetic drive, and sleep apnea), and what you can change tonight to improve sleep quality and recovery.

We also cover what to track so you actually know whether sleep is i...

Progress isn’t built during perfect weeks, it’s built during the chaotic ones.

In this episode, John and Luke walk through how to navigate holidays, travel, family events, and busy seasons without letting weeks of progress slip away. Instead of pretending life won’t get messy, they show you how to build a process that still holds when it does.
