I have some exercise physiology questions

I think it would be a great idea if TR released a plan that was geared towards general well-being/ longevity, as opposed to optimizing for racing. As we are beginning to learn, the two approaches are dramatically different. Peter Attia often says that he is training for the “centenarian olympics,” not an Ironman.

For the time being, I think that the traditional base, as opposed to sweet spot base, training plan most closely approximates what you desire, @Thomas_Coury.
