BREATH TO PERFORM – SCIENCE‑BACKED TOOLS FOR FASTER RUNNING
Dr Eric Harbour didn’t start with pace — he started with RESPIRATORY LIMITERS
In this lung‑expanding episode of The Training Science Podcast, Paul & Eric translate cutting‑edge breathing research into everyday coaching gold:

When your LUNGS, not your LEGS, hit the wall — spotting respiratory choke‑points
Nasal vs. mouth breathing — why, when & how to switch gears
Locomotor‑respiratory coupling (LRC) — syncing steps and breaths for efficiency
CO₂‑tolerance drills & apnea sets — building calm under metabolic fire
The “Breath Tools” framework — practical progressions you can use tomorrow
