Theory and powerpoint slides are cute.

Instagram GooRoos pointing out how another GooRoo is wrong is quite hilarious .

But results?

Results pay the bills.

So instead of me ranting about stroke volume until the cows come home...

...let's look at actual humans.

Four different people.

Different backgrounds.

All with individual goals.

The only thing they had in common?

They stopped treating cardio like punishment and started treating it like physiology.

#1 Andrew Martin

Andrew works as a Training Officer for the Fire Service.

Part of his job is testing firefighters' VO₂ max.

Not exactly a guy staring at a smartwatch while standing next to a treadmill fan.

Before the Canadian Death Race his VO₂ max was 44 ml/kg/min.

He ran the FMC protocols.

Eight weeks later?

52 ml/kg/min.

That is a massive increase in an already trained subject.

Then he spent the race running up and down mountains instead of negotiating with Jesus halfway through every climb.

#2 Bryan Boorstein

Coach.

Natural bodybuilder.

Former CrossFit competitor.

When I started working with him using these principles (full disclosure he was a private M3 1-1 client )

His 2K time was 7:23 - pretty darn good!

Then...

7:14.

Eventually...

7:03 at roughly 300 watts.

His comment?

It was faster than when he competed in CrossFit and was arguably in the best shape of his life.

No drugs, no peptides or anything crazy other than we pushed him hard. So much so that once he hit that number he changed goals. hahah. But he crushed it.

#3 Rena Rosenthal

Registered Dietitian.

More than twenty years in the field.

VO₂ max?

50 → 59 ml/kg/min.

The interesting part?

Recovery improved before the number did.

I see that all the time.

Your body often cashes the physiological paycheck before the dashboard catches up.

#4 Dylan Fowler

Favorite protocol?

The Escalating 6.

Six.

Minutes.

Per.

Day.

Results?

Higher HRV.

Lower resting heart rate.

Better VO₂ max.

His clients of all types reported increasing aerobic capacity too.

I've watched people spend longer arguing about Zone 2 on Instagram than this protocol actually takes.

Then there's Grinding Gary.

Gary has avoided cardio since approximately the invention of creatine monohydrate because somebody once told him it would dissolve his quadZ.

Gary lifts five days per week.

And also requires a tactical recovery period after carrying groceries up one flight of stairs.

Gary looks at Andrew.

Then Bryan.

Then Rena.

Then Dylan.

Studies the evidence...

...and quietly mutters,

"Yeah...but cardio kills gainZ."

Gary is why I occasionally have to lie down in a dark room. Don't be a Gary.

Notice something?

None of these people became endurance athletes. Leg shaving never entered the picture.

A $14,000 bike did not appear, and Tuesday did not suddenly become "zone 2 day."

They simply built a bigger engine.

And here's the part that makes the internet spontaneously combust...

A bigger engine doesn't steal your gainZ.

It lets you recover faster between sets.

Recover faster between sessions.

Do more high-quality work.

Which usually leads to...

...more gainZ.

Funny how physiology keeps refusing to cooperate with internet mythology.
