> [!warning] I suck at cardiovascular exercise. From what I've gathered, if you want to go beyond [[Minimum Viable Cardio]] to improve your [[Healthspan vs Lifespan|healthspan]], you should work bi-morally - focusing on [[Zone 2]] training for ~80% of the time you spend doing cardio, and the remaining 20% working [[HIIT]] to improve [[VO2 Max]]. This seems, in many cases, to result in 4 cardio sessions per week, where 3 of them are [[Zone 2]] training and the last one is some form of [[HIIT]]: ![[Cardio.png]] Basically, 3 or so workouts doing any of the [[Zone 2#Training]] methods, then a hard workout using any of the [[HIIT#Training]]. This slots into my [[Recommended Fitness Routine]] pretty effectively (although I'm using [[Yoga]] as one of the [[Zone 2]] days). Dr. Peter Attia talks about "maximizing the area of the triangle": ![[Pasted image 20250323100253.png|400]] I've also heard him use a 3-dimensional analogy (a pyramid), playing on our physical understanding of the world. In order to build a tall pyramid, you need a wide base. **** # More ## Source - [[Outlive]] & podcasts by Dr. Attia - Various other sources along the way, this was arrived at as somewhat of a consensus from lots of inputs over the past many months. ## Related
