Wearable tech has totally changed how I approach fitness, and MET tracking is no exception. My favorite tool is a good old-fashioned pedometer paired with a heart rate monitor—simple but effective. For example, my Fitbit gives me a rough idea of METs during walks or runs by combining steps and heart rate. It’s not lab-level precise, but it’s close enough for casual tracking. I also love how some gym equipment, like treadmills or ellipticals, displays MET values based on speed and incline. It’s a neat way to compare workouts. Of course, nothing beats professional-grade tools, but for everyday use, these gadgets work just fine.

Measuring the 'met'—or metabolic equivalent of task—is something I've dived into quite a bit, especially after getting obsessed with tracking my workouts and overall activity levels. The most straightforward tool is a heart rate monitor, since heart rate correlates pretty well with energy expenditure. I use a chest strap one because they tend to be more accurate than wrist-based sensors, though smartwatches like the Apple Watch or Garmin devices do a decent job too. They combine heart rate with motion data to estimate METs, though they can sometimes overestimate if you're just fidgeting a lot.

Another method I’ve experimented with is indirect calorimetry, which measures oxygen consumption to calculate energy expenditure. It’s the gold standard but super impractical for everyday use—you’d need to wear a mask hooked up to a machine. For most people, fitness trackers or apps that use established MET tables (like the Compendium of Physical Activities) are way more feasible. I’ve found apps like 'MyFitnessPal' or 'Strava' helpful for logging activities and getting rough MET estimates, though they rely on averages rather than personalized data. It’s fascinating how tech has made this stuff accessible, even if it’s not perfect.
