HIIT vs. Moderate Intensity Exercise - Which Is Better for Your Health? | Dr. Martin Gibala

3/17/20261 hr 47 min

Metabolic flexibility is your body’s ability to efficiently burn fat or carbohydrate depending on demand, may be one of the most important and least understood markers of long-term health. In this episode, I’m with Dr. Martin Gibala to explore the emerging science of Fat Max, why mitochondrial quality is central to both performance and longevity, and how sprint interval training produces comparable mitochondrial adaptations to traditional endurance work in a fraction of the time. Could the key to better metabolic health be less about the hours you log and more about how hard you’re willing to push?<...

    So many people are struggling to meet the physical activity guidelines. We should all be doing about 150 minutes a week of moderate to vigorous physical activity intensity.

  2. Gabrielle Lyon· Host0:10

    People struggle with time. So where would that be acceptable?

  3. Martin Gibala· Guest0:13

    There's a number of people, where you give them the option, an hour of traditional continuous, or you can do 10 minutes of really vigorous, which do you like? I really don't like that sprint training in the moment, but I certainly like it when I'm done in 10 or 15 minutes, and I would much prefer that to doing an hour or 90 minutes of the traditional approach. The studies also show that more vigorous physical activity will lead to greater improvements in VO2 max, and that's not only in healthy individuals. This is in individuals with many different chronic conditions.

  4. Gabrielle Lyon· Host0:47

    Talk to me about where high-intensity interval training could be applied to the regular person.

  5. Martin Gibala· Guest0:56

    It all comes back down to, do you have metabolic flexibility or not? One of the best ways to improve that is to boost your mitochondrial capacity, right? Boost your health.

  6. Gabrielle Lyon· Host1:05

    We're entering a new era where people are very interested in- Yeah ... female-specific exercise. Are there some differences?

  7. Martin Gibala· Guest1:12

    There might be some subtle differences there, but overwhelmingly, it's [gentle music] Dr.

  8. Gabrielle Lyon· Host1:26

    Martin Gibala, welcome to the show.

  9. Martin Gibala· Guest1:28

    Nice to see you again.
