VO2 Max
Definition
The maximum amount of oxygen your body can use during intense exercise, measured in milliliters of oxygen per kilogram of body weight per minute (mL/kg/min). It's widely considered the best single number for aerobic fitness. Many watches estimate it from heart rate during cardio.
How MoveTogether uses it.
MoveTogether does not score competitions on VO2 max, and it does not request it from Apple Health. VO2 max depends on genetics, body composition, and training history, so ranking people by it would reward lean cardio athletes regardless of effort.
On a watch it is also an estimate, usually updated only after outdoor runs with GPS. Cyclists, swimmers, and lifters can train hard for months and see it stand still. Track it in your wearable's own app as a long-term trend.

MoveTogether is on the App Store and Google Play. Bring any device that syncs to Apple Health or Health Connect, or just your phone, and start your first competition this week.
