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: Leroy Colbert’s high-volume late-1970s routine Why bodybuilding training changed so dramatically after the introduction of anabolic steroids Forcing Chris into a philosophy conversation: appeal to tradition fallacy, Chesterton’s fence, the Lindy effect, and Occam’s razor Evidence that anabolic steroids can build muscle without a resistance-training stimulus Why steroid-induced muscle growth cannot simply be dismissed as water weight or sarcoplasmic hypertrophy The dose-response relationship between testosterone and muscle growth Why “replacement” doses of testosterone may still produce supraphysiological effects at the muscle Join our Hypertrophy Past and Present Training group on TrainHeroic.com","meta_description":"In this episode of Hypertrophy Past & Present, Jake and Chris begin with Leroy Colbert’s late-1970s enormous volume training plan.
