EP 768: Is Muscle the Missing Piece in Your Training? 02/12/2026

EP 768: Is Muscle the Missing Piece in Your Training? In this episode, rejoins Trail Runner Nation discuss why muscle is the real engine behind endurance, performance, and long-term health, especially as runners get older. The conversation explores how and why we lose muscle over time, why this decline matters for speed, resilience, and injury prevention, and the encouraging truth that much of it is reversible. Alex explains the critical role of strength training, the importance of intensity and progressive load, and how endurance athletes can balance running with the work needed to maintain power. The discussion also challenges common myths about aging, showing that performance losses are not inevitable but often the result of training gaps rather than biology alone. For aging athletes and lifelong runners, this episode offers a practical roadmap for staying strong, capable, and competitive for decades. This discussion began from Alex's review of Michael Joseph Gross' book, "" Key Topics: The evolving understanding of muscle as a core component of human health, not just aesthetics or performance. Historical perspectives on muscle research, from ancient Greece to misconceptions over the centuries. The modern shift towards heavy lifting among elite athletes and implications for older adults. The inspiring work of Maria Fiaturone Singh on elderly resistance training and outcomes in musculoskeletal health. Practical advice for incorporating strength training into daily life with minimal equipment. The psychological and physical joys of feeling the movement of heavy lifting with purpose. How resistance training enhances posture, independence, and injury prevention in aging. Personal journeys—from bodybuilding to running, and reintegration of strength work in midlife. Overcoming mental barriers to strength training: finding routines you enjoy and tracking progress. The importance of consistent, accessible strength habits like bodyweight exercises and small routines.

EP 765: Aging as an Athlete - Quinn Brett on Redefining Life as an Athlete After Injury In this powerful episode, we sit down with our special co-host, and with climber, endurance athlete, and paraplegic adventurer for a conversation that stretches far beyond sport. We explore what happens when the body changes, identity is shaken, and resilience becomes a daily practice. Quinn’s story is one of dramatic transformation. Once a climber, guide, and search-and-rescue professional, her life changed forever after a catastrophic fall on El Capitan in 2017 that left her with a T11 ASIA A spinal cord injury. With honesty and clarity, Quinn explains what that diagnosis means, how it affects her body, and how it reshaped the way she sees herself and the world. But this episode is not about loss. It’s about endurance redefined. Drawing on her background in psychology, yoga, and ultra-endurance sport, Quinn shares how the mindset she built as an athlete now fuels her recovery and her future. Endurance, she explains, is no longer measured in miles or summits, but in the daily choice to keep moving forward, mentally and emotionally. The conversation weaves through the realities of aging, injury, and reinvention, highlighting the role of community, purpose, and curiosity in building a meaningful next chapter. Quinn’s eyes are firmly on the horizon, with goals that include open-water swimming and even triathlons, proof that adventure doesn’t end when life changes direction. This episode is a reminder that while our bodies evolve and our paths shift, the spirit of an athlete, the drive to explore, and the courage to adapt can remain boundless. Gold Nuggets Aging and injury can redefine, not diminish, the athlete’s journey Understanding spinal cord injuries fosters empathy and support Endurance is as much mental as it is physical Community, mindset, and purpose are essential for long-term resilience Links that you should check out: movie on Amazon Prime film Get the . /episode/index/show/trailrunnernation/id/39846420
