Variable Resistance, Peptides, and “Fast-Acting” Hormones: John Jaquish on Training Concepts and Biohacking Culture

About this episode

Cade Archibald interviews John Jaquish about variable resistance training and biohacking culture.

In this conversation, Cade Archibald sits down with inventor and author John Jaquish, PhD to discuss his background in fitness-adjacent tech and why he believes “variable resistance” training changes how people think about workouts. They trade perspectives on popular biohacking topics—like peptides, appetite control, and testosterone products—while emphasizing personal experimentation, training mechanics, and the challenges of separating hype from real-world outcomes. Along the way, Jaquish shares the origin story behind his projects (including OsteoStrong and X3), describes the training principles he promotes, and points listeners toward where they can explore his work online.
