Here’s a sentence that may get me politely uninvited from every longevity podcast on the internet:

Most lifters should stop worshipping Zone 2 cardio.

I said exactly that on Andrew Coates’ Lift Free and Diet Hard this week, and I can already hear the heart-rate-strap disciples stacking wood for the bonfire.

Good.

Zone 2 isn’t trash. It builds an aerobic base, helps fat oxidation, and can absolutely be useful.

Most people just pay too much for it.

The problem is the invoice.

To get the big return, Zone 2 often wants 3–4 hours a week of your life. That’s a fair trade for an endurance athlete with a bike tan and a calendar built around training.

For the meathead with a job, a family, legs to train, and a squat rack calling? Brutal deal.

That’s why I’m more interested in Zone 3.

Not puke-in-a-bucket intervals.

Not zen pedaling while you contemplate your childhood.

Zone 3 is the forgotten middle child of cardio: hard enough to matter, sane enough to recover from, and nasty enough to build an engine without eating your whole week.

On the episode, I walk through my 6-minute Zone 3 protocol — pacing, RPE, talk test, and how to plug it around lifting without turning your legs into wet cement.

Six minutes.

Your treadmill worship service can wait.

Before the cardio police kick in my door:

Steps still matter. Walking is not useless. Daily movement is a longevity lever, so keep racking it up.

The interference effect is also mostly overhyped for lifters doing sane doses. Real? Yes. Worth panicking over every time you touch a rower? Nope.

We also got into the Enhanced Games and whether creatine can save your brain when sleep gets murdered.

So yeah, normal Tuesday. haha.

Much love and shorter, meaner cardio,
Dr. Mike

PS — The exact 6-minute Zone 3 block is in the back half of the episode. Go steal back two hours of your week.

PPS — The Flex Diet Certification opens Monday. If you want the full system for nutrition, training, recovery, metabolic flexibility, and making all this stuff actually fit into real life, that’s where I’d point you next.
