📺 This article is the companion to this week's video: The Cardiovascular Reserve — Watch on YouTube →
In the video, I shared something personal — a calcium finding in one of my coronary arteries that forced me to look honestly at how I had been training. What the scan also confirmed was a cardiovascular system that was, by every functional measure, performing well above average for my age.
The difference between those two data points — a structural finding and a functional advantage — is what this pillar is about. And it points to the single most important variable I've identified for maintaining quality of life into your seventies and eighties: the cardiovascular reserve you build right now.
This article gives you the actionable protocol behind the science we covered in the video. Training zones. Weekly structure. What actually builds arterial compliance versus what just burns calories. And the VO2 max targets that matter for long-term functional independence.
