3 Wearable Metrics That Predict Longevity: VO2 Max + Sleep Score + HRV 

Your smartwatch spits out three numbers that look “important”… but most people have no idea what they actually mean: VO₂ max, Sleep Score, and HRV.
 
In this episode, I break them down the adult way:
 
What each metric really measures
 
How accurate wearable estimates are (and where they fail)
 
What the science says they’re associated with long-term health outcomes
 
The simplest, highest-leverage ways to improve each one without obsessing
 
Key idea: these numbers are signals, not sentences. Learn to read the trend, adjust your training, and stop getting guilt-tripped by your wrist.
 
Comment “STACK” if you want the next episode: How to combine VO₂ max + sleep + HRV into one weekly protocol.
