Fitbit adds new features for users with Cardio Load and Target Load

Fitbit is introducing two new features, Cardio Load and Target Load, to many of its devices, including older models. These features will be available through the Fitbit app on smartphones, not directly on the wearables. Cardio Load measures the intensity of exercise over time, helping users monitor their fitness levels. Target Load allows users to set personal goals for their Cardio Load. The rollout of these features has already begun. Users should check for updates in the app to access the new stats.
