    Should You Restrict Water on Show Day? (Most Get This Wrong) | J3U Podcast Ep. 248

    Most flat stage looks come from loading too late and cutting too much water. In this episode, we break down how we peaked two athletes for the 2026 Olympia: a Men's Physique competitor who came in about six pounds heavier, and a 212 competitor who held more fullness than last year. We cover aggressive carb loading, the carryover effect of food, and fluid on show day. If you're serious about competing, this will help you decide how hard to load in the days before your show, instead of chasing fullness all show day. 🎟️ Save 20% on ANY J3U Program with code J3UPOD 👉 https://j3u.site 🎓 Courses Level 1 — Foundations of Evidence-Based Bodybuilding → https://j3u.site/level1 Applied Hypertrophy Optimization → https://j3u.site/aho Female Physique Module → https://j3u.site/female All J3U Programs 🏋️‍♀️ Hourglass (Female): https://j3u.site/hourglass 💪 X-Frame (Male & Female): https://j3u.site/xframe 🏋️ Get Coaching From J3U https://j3u.site/coaching 👨‍⚕ Marek Health Comprehensive blood work analysis and professional medical guidance 10% off your first comprehensive J3U panel + additional markers Code: J3U Affiliate link: https://marekhealth.com/J3U

    Don't Make These Growth Hormone Mistakes Before Your Next Push Phase | J3U Podcast Ep. 247

    Most of what you hear about growth hormone in bodybuilding is a myth. In this episode, we break down the growth hormone myths you sent us on Instagram. We cover why GH shines alongside androgens rather than on its own, why it absolutely works for women in the right hormonal environment, and how to dose it without chasing diminishing returns. If you're serious about enhanced bodybuilding, this will help you decide when to bring growth hormone in, and how far to push it before the side effects outweigh the gains. 🎓 Free Level 1 Masterclass John and Luke are hosting a free live Level 1 Masterclass on how we turn the research into real training decisions.

    Why Your Peak Falls Apart Overseas (Travel Traps Explained) | J3U Podcast Ep. 246

    No air conditioning, the wrong voltage and a tanner who can't understand you can cost you on show day. In this episode, we break down how to compete internationally after my shows in Austria and Germany. We cover managing heat and sweat when venues and hotels skip air conditioning, packing so you barely have to source food abroad, and timing your flight so you land with days to settle. If you're serious about stepping on a stage abroad, this helps you decide how early to fly and what to pack so the trip doesn't cost you your peak.

    Frequency vs Volume: What Really Builds a Lagging Muscle | J3U Podcast Ep. 245

    Adding more sets to the same session is why your weak body part still will not grow. In this episode, we break down how to actually bring up a lagging muscle: picking the machine that fits your body instead of the lift you are attached to, training the weak part first in the session, and using frequency as the tool that lets you carry more quality volume. If you're serious about fixing a weak body part, this will change how you decide between adding another set and splitting that volume across another session. 🎓 Free Level 1 Masterclass John and Luke are hosting a free live Level 1 Masterclass on how we turn the research into real training decisions.

    When Should You Stop Competing in bodybuilding? | J3U Podcast Ep. 243

    When should you stop competing in bodybuilding, end your contest prep, or do another show?

We discuss judging feedback, whether your weaknesses are realistically fixable, the financial and health costs of extending contest prep, and when doing another show can actually be valuable. We also talk about the mental side of competing and how to make the decision without letting emotion dictate your next move.

    How to Peak an IFBB Pro for Show Day: Real Peak Week case Studies | J3U Podcast Ep. 240

    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.
