Podcast you've probably heard of Hit.

High-intensity interval training.

In fact, you may feel so familiar with the idea that you think you understand it.

But do you?

People often hold some popular misconceptions about Hit, and today we'll unpack what some of those are with Dr. Martin Gabala, a foremost researcher of this fitness modality and the author of The One Minute Workout. Science shows a way to get fit that's smarter, faster, shorter.

Martin explains the main underappreciated advantage of it, which revolves around the intensity

duration trade-off. The higher intensity you make exercise, the shorter your

workouts can be, while still triggering improvements in metabolism, cardiovascular

health, and mitochondrial capacity. We get into the fact that the intensity of it needn't be as high as you might think and that, contrary to popular belief,

sprinting at intervals is actually a predominantly aerobic rather than anaerobic workout.

Martin answers questions like whether Zone 2 cardio has an advantage over hit,

if the so-called afterburn effect of hit is real, if you can do hit if you're older or have heart problems,

and whether you should worry about the way hit can raise

cortisol in the body. He also shares specific hit workouts you can do, including a

walking interval workout and one of the best higher intensity protocols to try.

So you are a professor of kinsiology. Martin Gabala, welcome to the show. Thanks for having me.

So you are a professor of kensiology at McMaster University in Canada,

and you spent a lot of your career researching high intensity interval training or hit. I'm curious what led you down that path?
