Endurance Training

What it is

• Longer aerobic/cardiorespiratory work above Zone 2 Cardio duration/intensity (incl. fasted endurance).

How it works

• Broad cardiovascular + mitochondrial adaptations; aerobic work above the lactate threshold for ≥10 min can also trigger an exercise-induced GH pulse.

Goal relevance

• Cardiorespiratory fitness/longevity; MOTS-C preferentially benefits endurance (slow-twitch) capacity and is synergistic with (not a replacement for) endurance work.

How to do it

• Progressive volume; mix with Zone 2 base.

Cautions

• Overtraining/under-recovery if stacked with aggressive caloric deficit.
