You Don't Need Heavy Weights to Build Muscle

<p>In this episode of Fuelin Sessions, Scott is joined by applied sport scientist Jonah Rosner (ex-NFL, Nike Running Performance Lab NYC). They discuss why mechanical tension — not heavy weight — drives muscle growth, how blood flow restriction builds similar muscle at 20–30% of your max, who benefits most from injured athletes to hospital patients, and the practical protocol: limb occlusion pressure, the 30-15-15-15 scheme, and BFR&#39;s role in recovery and pain relief.</p><p><br></p><p><a href="https://marathonscience.beehiiv.com/subscribe" target="_blank" rel="ugc noopener noreferrer">Newsletter</a></p><p><a href="https://www.instagram.com/rosnerperformance/" target="_blank" rel="ugc noopener noreferrer">Instagram</a></p><p><a href="https://marathonscience.beehiiv.com/foot-calf-strength-guide-new" target="_blank" rel="ugc noopener noreferrer">Free Foot and Calf Strength Plan</a></p><p><strong>BFR papers</strong></p><p><a href="https://pubmed.ncbi.nlm.nih.gov/40079571/" target="_blank" rel="ugc noopener noreferrer">Loenneke et al. 2025, Twenty-five years of blood flow restriction training: What we know, what we do not know, and where to next?</a> </p><p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC12948889/" target="_blank" rel="ugc noopener noreferrer">Kataoka et al. 2025, Submaximal low-load resistance exercise with blood flow restriction produces similar results to low-load exercise to failure for muscle size and strength, but not endurance. </a></p><p><a href="https://physoc.onlinelibrary.wiley.com/doi/10.1113/JP290955" target="_blank" rel="ugc noopener noreferrer">Peden et al. 2026, Sprint-interval training with post-exercise blood flow restriction increases mitochondrial content and respiration. </a></p><p><br></p><p><a href="https://physoc.onlinelibrary.wiley.com/doi/10.1113/JP289806" target="_blank" rel="ugc noopener noreferrer">Lavigne et al. 2025, Physiological mechanisms underlying enhanced performance after blood flow-restricted exercise training in elite endurance athletes. </a></p><p><a href="www.instagram.com/getfuelin " target="_blank" rel="ugc noopener noreferrer">⁠⁠⁠⁠⁠</a></p><p><a href="www.instagram.com/getfuelin " target="_blank" rel="ugc noopener noreferrer">Fuelin on Instagram⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a> </p><p>⁠<a href="https://www.fuelin.com/?utm_source=podcast&utm_medium=shownotes&utm_campaign=weeklyepisodes&utm_term=mktg&utm_content=spotify" target="_blank" rel="ugc noopener noreferrer">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Check Out The Fuelin App⁠⁠</a></p>
