  • 226. Fast Comes Last: Getting Back to Running the Right Way | Dr. Drew Short
    May 26 2026

    Most runners are one bad training week away from an injury they never saw coming, and the way they think about shoes, strength, and recovery is probably making that worse.

    Dr. Drew Short specializes in working with runners at PhysioRoom, and his approach to running injury recovery starts somewhere most people wouldn't expect: months back in an athlete's training log. The culprit behind most injuries isn't a single bad run. It's accumulated load, under-fueling, or a strength gap that quietly grew until something gave out. When the mechanical picture looks clean, Drew digs deeper, sometimes all the way to blood work and nutritional consults. Multiple tendon issues flaring up in different parts of the body at once? That's a systemic story, not a mechanical one.

    The calf conversation is worth sitting with. Runners stretch it religiously and almost never strengthen it the way running actually demands. The soleus does significant work during each stride, but only when the knee is bent, which is almost never how people train it. A calf that always feels tight is probably asking for load, not length.

    On the trail running vs. road running question, the differences go deeper than terrain. Strength demands, stability requirements, and pacing strategy all shift in ways that catch road runners off guard when they head onto the trails. And carbon-plated shoes? Both Drew and Dr. Ficks agree they have a place, but earning them matters more than buying them.

    Quotes

    • "The downside to under-fueling is you're going to hit a brick wall. The downside to over-fueling is maybe a rumbly stomach…I'd rather be on that end of the spectrum." (14:58 | Dr. Drew Short)
    • "You might meet the rep scheme on a calf raise, but whenever you start making it more ballistic and you start using the tendon more, it doesn't like that. The rate of fire is just a lot slower on that side." (25:50 | Dr. Drew Short)
    • "Stiffer tendons or more robust tendons — that's just free energy. If you're able to use that elasticity like a rubber band whenever you hit the ground, that's less that the muscles are having to push off." (33:19 | Dr. Drew Short)
    • "If your calf always feels like it needs to be stretched, honestly, your tendon probably needs some load. You probably do need to be doing some heavy slow resistance through that tendon. Otherwise, you just keep stretching it all day every day." (34:32 | Dr. Drew Short)
    • "If I'm doing a long effort and I can still breathe just through my nose, I know I'm gonna be fine at hour three, hour four." (48:26 | Dr. Drew Short)

  • 225. The Code to Sleep Hygiene
    May 19 2026

    Sleep isn't a luxury you negotiate with; it's the biological foundation every other health habit is built on, and most people are getting far less of it than they think.

    Dr. Andrew Fix revisits one of the show's most foundational episodes for Better Sleep Month, and the timing feels personal. A new baby at home has a way of clarifying just how much everything falls apart when sleep does. Drawing from Matthew Walker's landmark book Why We Sleep, this episode makes a compelling case that sleep deprivation isn't just fatigue. It's a direct line to cancer, cardiovascular disease, dementia, weight gain, and a compromised immune system.

    Here's a question worth sitting with: if you went to bed at 10 and woke up at 6, did you actually get eight hours of sleep? Probably not. Time in bed and time asleep are not the same thing, and that gap is where most people are quietly losing ground.

    Dr. Fix gets practical without being prescriptive. A consistent sleep schedule, a cooler and darker room, cutting caffeine earlier than feels necessary, and keeping alcohol away from bedtime are the kinds of shifts that build real resilience over time. He also draws a connection that often gets overlooked in fitness culture: sleep is where recovery actually happens, and poor sleep throws off the hormones that regulate hunger, making weight management an uphill battle no matter how clean your diet is or how early you get to the gym.

    What would change about your daily habits if you treated sleep as seriously as your workouts or your nutrition? That's the real question this episode leaves you with.

    Quotes

    • “I think it's a shock to nobody that sleep is the most important thing in our lives. If we don't get enough of it, pretty much every major function of our body is going to suffer.” (02:37 | Dr. Andrew Fix)
    • "The amount of time that you spend in bed that you think you are asleep does not equal or correlate to the amount of time that you actually sleep." ( 06:27 | Dr. Andrew Fix)
    • “I do have a change in my sleep quality when I cut that caffeine out earlier. So, avoiding caffeine and nicotine, in theory, will help with your sleep quality.” (13:52 | Dr. Andrew Fix)
    • “You want your brain to be planning to go to bed when you get in bed. You want your body's cycle to be just so in tune with, ‘Oh, this is where I come when I want to go to sleep.’” (20:19 | Dr. Andrew Fix)
    • “All of the professional athletes that we watch on television and whatnot, I can tell you that they are putting a much higher emphasis on sleep than we do in our normal lives.” (31:59 | Dr. Andrew Fix)

  • 224. The Recipe to Lifelong Wellbeing | Eileen Kopsaftis
    May 12 2026

    Aging gets blamed for a lot of things that may have more to do with disuse, fear, and incomplete advice than the number of candles on your birthday cake.

    Dr. Andrew Fix talks with physical therapist Eileen Kopsaftis about pain, aging, and strength through a lens that challenges the usual story of decline. Eileen questions the idea that weakness, balance issues, loss of independence, and chronic pain are simply part of getting older. Some of these changes may be common, but are they truly normal?

    Andrew and Eileen unpack why pain often points to a bigger movement story. A shoulder issue may trace back to an ankle. Foot pain may connect to the hips. A limitation may have less to do with the part that hurts and more to do with the way the whole body works together.

    They also talk about strength, stairs, muscle loss, and the subtle ways convenience can speed up physical decline. What happens when we stop taking the stairs? How much of aging is shaped by what we believe our bodies are capable of? This episode is a smart reminder that the body is a system, and aging can look very different when we keep building capacity instead of accepting decline as destiny.

    Quotes

    • “You have to believe that your body was designed to perform based on how you work it, based on how you feed it, based on how you live your life.” (Eileen Kopsaftis | 16:04)
    • “There is a choice. If you believe you're gonna decline no matter what you do, you're not gonna do anything.” (Eileen Kopsaftis | 18:20)
    • “The human body is not designed on a cellular level to decline. When you're doing the right things the right way, your body responds. doesn't matter how old you are.” (Eileen Kopsaftis | 26:45)
    • “But as soon as that person stops having to climb stairs, they decline.” (Eileen Kopsaftis | 40:43)
    • “It's important for people to remember that they're a whole body and they're not a body part.” (Eileen Kopsaftis | 56:37)
