Female Bodybuilding PEDs Explained (What Coaches Won’t Tell You) | J3U Podcast Ep. 230

What female IFBB pros are actually using to turn pro might surprise you. In this episode, we break down the real PED protocols being used across Bikini, Wellness, Figure, and Women’s Bodybuilding — and why most female competitors are starting with the wrong approach. We cover HRT, DHT derivatives, Masteron vs Primo, escalation strategies, side effects, coaching mistakes, and what actually drives progress long term. If you’re a female competitor, coach, or serious physique athlete, this is one of the most honest conversations you’ll hear about female PED use in bodybuilding.

⁠How to Make Weight in Classic Physique Without Losing Muscle | J3U Podcast EP. 228

How to make weight in Classic Physique without losing muscle, ruining your look, or sabotaging your contest prep. Making weight in Classic Physique is one of the hardest parts of contest prep — especially when you’re too big for your class. In this episode, we break down how to manage weight cap bodybuilding prep, when a physique athlete may need to move out of Classic, how to preserve muscle while making weight, and the biggest mistakes coaches make when trying to bring athletes down too aggressively. We also discuss refeeds vs de-load output days, staying ahead during prep, GH timing, bodyweight manipulation, and how to decide if Classic Physique is still the right division for you.

Best Training Split for Muscle Growth (Upper Lower vs PPL) | J3U Podcast Ep. 226

Still stuck wondering if upper/lower or push-pull-legs is actually best for muscle growth? In this episode, we break down what actually matters when choosing a training split, how much volume you really need, and why the “best” split depends on your recovery, weak points, and goals. We also cover whether cardio hurts leg growth, how often to train body parts, and what to do if recovery or sleep is limiting progress.

En fantastisk app med et enormt stort udvalg af spændende podcasts. Podimo formår virkelig at lave godt indhold, der takler de lidt mere svære emner. At der så også er lydbøger oveni til en billig pris, gør at det er blevet min favorit app.

Rigtig god tjeneste med gode eksklusive podcasts og derudover et kæmpe udvalg af podcasts og lydbøger. Kan varmt anbefales, om ikke andet så udelukkende pga Dårligdommerne, Klovn podcast, Hakkedrengene og Han duo 😁 👍
Podimo er blevet uundværlig! Til lange bilture, hverdagen, rengøringen og i det hele taget, når man trænger til lidt adspredelse.
