This week on the Garage Gym Athlete Podcast, we're running three completely different scientific studies through the grinder—and none of us saw each other's ahead of time. Expect surprises, arguments, and some actionable training takeaways you can start using immediately. Jerred digs into a kettlebell snatch protocol that boosted VO₂ max without running. Joe explores how dietary nitrates (think beets, spinach, arugula) improve isometric endurance by 25%. And Dave breaks down a 2025 study showing how heavy strength work dramatically improves running economy, durability, and time-to-exhaustion in well-trained runners. We also kick things off with an update on last week's isometric training experiment—spoiler: it was brutal—and end with a practical roundtable on supplements we actually use. If you train in a garage gym, want science-backed performance strategies, and enjoy a little misery mixed with progress…this one's for you. 00:00 – Intro: This week's study mash-up 00:30 – Isometric training update & why Jerred is wrecked 02:25 – Immovable objects, heavy loads & iso strategy 03:47 – Dave digs into CNS fatigue from the iso session 04:52 – Transition: Let's get into the studies 05:16 – Study 1: Strength training improves running performance 08:48 – 31% improvement in time-to-exhaustion 10:27 – Jerred on heavy lifting for runners 12:04 – Joe on balancing strength, speed & endurance 13:56 – The truth about soreness & "gaining mass" fears 15:28 – Study 2: Nitrates boost isometric endurance (Joe) 18:48 – How much beets/spinach you actually need 19:26 – Joe's real-life beet adventure (never pickled…) 20:53 – Study 3: Increase VO₂ max by 6% with kettlebells (Jerred) 21:16 – VO₂ max simplified — oxygen demand & oxygen debt 23:16 – The 15s on / 15s off kettlebell snatch protocol 25:17 – Circuit training vs kettlebell intervals 27:39 – How to implement the protocol in real training 30:36 – Kettlebells vs running for conditioning 33:32 – Supplement roundtable: what we actually take 34:29 – Joe: nitrates & tart cherry 36:05 – Dave: creatine, protein & coffee 39:28 – Jerred: electrolytes & hydration 42:45 – Are electrolytes supplements or just life? 44:22 – Closing thoughts & "Kill Comfort" reminder
