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...

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...

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. Newsletters: David Protein Bar Lawsuit: A deep dive into the David Bars lawsuit that breaks down what’s actually happening with EPG, calories, and real-world physiology, so you can understand what...

You ever have one of those nights where you tell yourself“I’m just gonna check one thing real quick” …and three hours later you’re deep in a PDF about non-absorbable triglyceride analogs wondering if vitamin K depletion is the hill you die on? That was me last night and previous days too. ..Because David Bars got sued. And once a protein bar lawsuit hits federal court, my brain does not let that go.Not because I care about internet drama.......but because I care about dose-response curves,...

In this episode of the Flex Diet Podcast, I sit down with coach Kevin Dineen to talk about where fitness and healthcare are headed and whether their merger is a net positive or negative. We dig into why people still default to asking physicians about training and nutrition, the problems created by siloed systems, and what a more client-centered model could look like with coaches, PTs, massage therapists, and physicians collaborating under one roof. We also discuss the pros, cons, and...

Hola from snowing Minnesota, as there is a snow-apocalypse going on. I’m back at the airport on my way to Vegas this AM via flight #5. Here's what went down this week. Newsletters: Metabolic Flexibility, Fasted Cardio & VO₂ Max: I joined the Renaissance Periodization Podcast with Nick Shaw to break down metabolic flexibility, why carbs vs. fat matter for performance, and practical ways lifters can use cardio, fasting, and fuel timing to improve body composition and work capacity. I Ran...

The other day I talked about getting bloodwork done and why it matters (go HERE if you missed it) Simple enough, right? Get the test.Look at the numbers.Pretend you understand them.Take action. But here’s the part most people miss… Bloodwork is not a movie.It’s a screenshot. One frozen frame of a biological horror film that’s running 24/7 inside your meat-suit. If you think one snapshot tells the whole story, that’s like watching 3 seconds of a deadlift and deciding whether the lift passed or...

The other day I finally did something I tell clients to do all the time, but like most people… I put it off longer than I should have. I ran a full set of bloodwork. Not because I felt terrible.Not because anything obvious was wrong.Not because my doctor told me to. It was more that quiet voice that shows up once you get a little older… the one that says: You might feel fine, but that doesn’t mean everything under the hood agrees with you. So I signed up through Function Health and ran a full...

I recently joined Nick Shaw on the Renaissance Periodization Podcast for a wide-ranging discussion on metabolic flexibility, fuel systems, and practical strategies for improving body composition and performance. We dug into how the body switches between carbohydrates and fat as fuel depending on the demands of the activity. High-power efforts rely heavily on carbohydrates because they can generate ATP faster, while lower-intensity work shifts more toward fat metabolism. We also covered why...
