We started with how I went from mechanical engineering into exercise physiology… and somehow ended up talking about metabolic flexibility, HRV, cold exposure, creatine, peptides, women’s metabolism, and why the right music can make you lift heavier. Which, honestly, is a pretty accurate snapshot of how my brain works. My engineering background is a major...

Most people understand the primary drivers of hypertrophy — mechanical tension, load, and progression. What they miss are the secondary and tertiary factors that determine whether those drivers can actually be accessed consistently over time. In this episode, Ben and I unpack how: Aerobic...
