Zone 2 Cardio: What the Science Actually Says (and What to Do Instead)
|
As you saw earlier today, the Flexible Meathead Cardio course level 1 is open again so this is perfect timing to unpack the Zone 2 cardio debate with my friend Kristi Storoschuk, a PhD candidate in exercise physiology. We dig into what “zone 2” really means (including lactate thresholds and why common proxies like heart rate and the talk test can miss the mark), where the 80/20 endurance model came from, and why messaging around zone 2 for mitochondrial function, fat oxidation, metabolic flexibility, and health may be overstated, especially for the general population. Kristi explains why higher intensities often produce equal or better mitochondrial and performance-related adaptations, how training volume and population context change the conversation, and where low-intensity work like walking may still fit. 🎧 Listen/Watch here: Zone 2 Cardio: What the Science Actually Says << iTunes Episode Chapters:

There are three kinds of lifters. The first one trains like the apocalypse is personally coming for him every single session. Every session is a suffer-fest and even weight training is turned into a ritual of snorting pre-workout off the gym sink in an effort to put forth enough effort of beyond failure training to make Mike Mentzer's ghost smile down upon their heroic gym deeds. Every conditioning piece is used to its fullest degree as if it committed a war crime against his own nervous...
Hola from the frozen hellscape of Minnesota, where I’ve been rudely ejected from the warm embrace of Vegas and dropped straight into a climate that feels like it’s trying to repossess my soul. I dragged my jet-lagged carcass out of bed the other day, layered up, and hit my AM row in the 43 F Extreme Human Performance Center (aka my garage gym) anyway… because I am not a coward. haha Then I punished myself further with some rower sprints, just to remind my body who’s in charge before I head...
Wow…what a week. I tried to take 5 flights just to get to a Mastermind in Vegas—finally rolled in about a day late thanks to a Minnesota snowstorm. Then straight back into reality with a pile of deadlines waiting for me when I got in late Wednesday. Good times. Here's what went down this week.
