5 Apple Watch Health Metrics You Should Track in 2024

The most useful, actionable, and practical Apple Watch Metrics

As a data scientist, I’ve learned the value of having clear, measurable metrics to track progress. This approach isn’t just for data; it’s incredibly useful for personal health too. For a long time, I’ve been passionate about staying healthy, but I always struggled with how to measure my progress.

It wasn’t until this year that I realized how powerful the Apple Watch and the Health App were. Not only do they track a variety of metrics but they also measure them quite accurately.

And so, using these technologies I’ve set five personal health goals based on five of the most useful and practical metrics in the Health App. These are goals that you can set and track too! With that said, here are the 5 Apple Watch Health Metrics You Should Track in 2024:

Metric #1: Achieve an Above Average VO2 Max

VO2 max, the maximum amount of oxygen your body can use during intense exercise, is a key indicator of cardiovascular health and overall fitness. An above-average VO2 max signifies a strong aerobic fitness level. Your Apple Watch can estimate your VO2 max during vigorous outdoor walks, runs, or hikes. Aim to improve this metric steadily through regular, intense workouts.

If you want to better understand what VO2 Max is, check out my previous article:


  • A study titled “Survival of the fittest: VO2 max, a key predictor of longevity?” found that cardiorespiratory fitness, as measured by VO2 max, is a strong and independent predictor of all-cause and disease-specific mortality. The study emphasizes the importance of regular exercise in promoting life expectancy.
  • Another study, titled “Higher VO2 max is associated with thicker cortex and lower grey matter blood flow in older adults”, showed that higher VO2 max is associated with better cerebral
