  • Your Muscles Have a Memory, But It's Not What the Gym Bros Mean
    Oct 7 2026

    Muscle memory is real — it's just stored in the DNA, not the movement pattern. This episode digs into the emerging science of epigenetic muscle memory: how your muscles retain a molecular record of past training that can fast-track regained fitness after a long break, and what that means if you've ever felt guilty about losing your gains. Spoiler: that six-month gap might matter a lot less than you think.

  • You're Not a Morning Person (Your Liver Is Just Running Three Hours Behind)
    Sep 30 2026

    Everyone talks about sleep cycles, but almost nobody talks about the fact that your organs keep their own separate clocks — and when your eating schedule fights your liver's circadian rhythm, you're not just tired, you're metabolically out of sync in ways that affect everything from blood sugar regulation to how efficiently you burn fat. This episode gets into the science of peripheral clocks, why the timing of your first meal may matter more than what's in it, and what 'eating with your biology' actually looks like when you strip away the intermittent fasting hype.

  • Your Muscles Don't Grow at the Gym (And the Recovery Window Most People Miss by Exactly 47 Minutes)
    Sep 28 2026

    You've been told rest days are for the weak — turns out, rest days are literally where the gains happen. In this episode, we dig into the actual biology of muscle protein synthesis, why the post-workout window is real but wildly misunderstood, and how the same people who optimize every rep are accidentally sabotaging their results in the two hours that follow. No supplements required, no bro-science allowed.

  • The 90-Minute Lie: How Your Brain Fakes a Full Night's Sleep (And What It's Actually Doing Instead)
    Sep 23 2026
    You slept eight hours but still woke up wrecked — so what actually happened in there? This episode dismantles the myth that sleep is one long recovery block, revealing how your brain cycles through wildly different biological jobs each night, and why the *timing* of when you wake up may matter more than the total hours you clock. We get into the surprising science of sleep architecture, what happens when those cycles get cut short, and a few dead-simple shifts that can change how you feel by tomorrow morning.

  • The Hunger Hoax: Why Your Body Lies About Being Hungry (And the 20-Minute Window That Exposes It)
    Sep 16 2026
    Your stomach growls, your brain screams 'eat now' — but is that actually hunger, or is your body running a con? This episode dismantles the popular notion that hunger is a reliable signal, digging into the ghrelin-leptin feedback loop, how ultra-processed foods hijack satiety cues, and why the timing of when you feel full matters as much as what you ate. No diet ideology, no calorie-counting dogma — just the actual mechanics of appetite your body never explained to you. Hosted by Simplecast, an AdsWizz company.

  • The 90-Minute Lie: Why Your Sleep App Is Measuring the Wrong Thing (And What Actually Restores You)
    Sep 9 2026
    Everyone's chasing 8 hours and a high sleep score — but the research suggests we've been optimizing for the wrong metric entirely. This episode dismantles the oversimplified sleep cycle narrative, digs into what slow-wave and REM sleep actually do at a cellular and neurological level, and explains why two people can log identical hours and wake up worlds apart. No sleep hygiene checklists — just the science of what restoration actually looks like, and the surprisingly mundane levers that move it. Hosted by Simplecast, an AdsWizz company.

  • Zone 2 or Zone Out: The Boring Workout That Outperforms Everything Else (And Why Nobody Sells It)
    Sep 2 2026
    Everyone's chasing HIIT classes, personal records, and that post-workout dopamine hit — but the most robustly supported longevity exercise in the peer-reviewed literature looks embarrassingly undramatic. This week, we dig into Zone 2 aerobic training: what's actually happening at the cellular level, why it's nearly impossible to do correctly without a heart rate monitor, and why the fitness industry has a financial incentive to keep you gasping instead of cruising. No tracker required — though after last week's sleep score autopsy, you might be side-eyeing yours anyway. Hosted by Simplecast, an AdsWizz company.

  • The 90-Minute Lie: Why Your Fitness Tracker's Sleep Score Is Probably Gaslighting You
    Aug 26 2026
    Your wearable says you got 7.5 hours and an 84 sleep score — so why do you feel like you were hit by a truck? In this episode, we dig into what consumer sleep trackers actually measure versus what sleep scientists measure, and why the metric you're optimizing for might be the wrong one entirely. We'll cover sleep architecture, the specific stages your body actually needs, and the surprisingly counterintuitive evidence on what moves the needle. Hosted by Simplecast, an AdsWizz company.
