Most competitors don't lose their physique during peak week, they lose it in the month leading up to the show.
In this episode, we break down the biggest mistakes bodybuilders make during the final four weeks of contest prep, including rushing fat loss, making emotional decisions, changing drugs unnecessarily, overdoing posing, and mismanaging training fatigue. If you want to bring your best physique to the stage, this episode will help you avoid the mistakes that cost competitors their best look.

Peak week isn't a one-size-fits-all process—and these IFBB pro case studies show exactly why.
We break down what happened with our athletes at Texas Pro, including how we adjusted food, fluids, loading, stage-day weight ranges, and peak-week decisions based on how each athlete was responding. We also talk through the coaching challenges that come with working with high-level pros, from managing an athlete who fades quickly to making sure ego never gets in the way of getting better.

Most lifters don't need a new workout—they need better exercise selection.
In this episode, we break down the exact framework we use to evaluate every exercise in a bodybuilding program. We cover movement redundancy, range of motion, fatigue cost, progression, and how to choose lifts that actually match your body instead of blindly following trends.
If you want more growth without adding more volume, this episode will change how you build your training forever.

How often should you train each muscle for maximum muscle growth? The answer isn’t as simple as “twice a week.”
In this episode, we break down the science behind training frequency, why more sessions don’t always produce more muscle, and how elite physique coaches actually decide when to increase—or decrease—training frequency. We also discuss volume, specialization phases, recovery, exercise selection, and the biggest mistakes lifters make when designing their training splits.
If you’re trying to build more muscle, bring up lagging body parts, or optimize your bodybuilding program, this episode will help you make smarter programming decisions.

Are electrolyte powders actually improving your workouts, or are most bodybuilders paying for something they don't need?
In this episode of the J3 University Podcast, we break down the science behind electrolytes, hydration, sodium, potassium, magnesium, sweat loss, and resistance training. We explain when electrolyte supplements can improve performance, when plain water is enough, and the few situations where adding extra sodium actually makes sense during contest prep or training in extreme heat.
If you're a bodybuilder, physique athlete, or coach looking to optimize hydration and performance without wasting money on unnecessary supplements, this episode gives you the evidence-based answer.

Has science-based bodybuilding started creating more myths than answers?
In this episode, we break down five popular "science-based" training concepts that may be doing more harm than good when taken to extremes. We discuss training to failure, optimal exercise selection, volume, frequency, and stretch-mediated hypertrophy and explain what the research actually says versus how it's often interpreted online. If you're a coach, competitor, or serious bodybuilder, this conversation will help you separate evidence from internet hype.
