Do we need Zone 2 cardio? New evidence suggests it improves recovery between sets by boosting mitochondrial density.

The interference effect is way overblown. 20-30 mins of low intensity won't kill your gains.

If your heart rate is 160 after a set of 5 squats, your aerobic base sucks and you need cardio.

Ouch. I feel targeted.

Better mitochondria means faster phosphocreatine resynthesis.

Exactly! It literally allows you to take shorter rest periods or do more work per session.

Does high rep lifting (20+) provide the same mitochondrial benefit?

Somewhat, but the local muscular fatigue is different from central cardiovascular adaptations.

I started walking 10k steps a day and my squat sessions feel much easier.

Walking is underrated as an aerobic builder.
