From the conversations
What outcome does David Stewart target in his training approach?
David Stewart of Super Age at 67 and 11.4% Body Fat: What Real Longevity Looks Like · 28:06 ↗“I think that the difference here is that it's we're looking at the target is resilience. So durable capacity and if you're gonna talk about that then you sort of bring some other elements in here.”
