There’s a measure on the Apple Watch called VO₂ max that I check from time to time.
VO₂ max is an estimate of cardiovascular health – how efficiently your body uses oxygen during exercise. The Apple Watch measure is not perfectly accurate, but it works as a directional indicator.
Recently, I took a break from my 15-minute morning hill runs for a 2 weeks period – first while recovering from being under the weather, then while traveling.
When I checked again, my VO₂ max had dropped a notch.
Our bodies don’t lie.
Our fitness is just the sum of small, consistent actions – and the absence of them shows up quickly.
Consistency compounds.
