Fitbit is rolling out Cardio Load and Target Load features to more of its watches and trackers, providing users with a numerical score that measures the strain on their cardiovascular system during exercise and daily activities. The metrics help users track their progress and avoid overtraining by considering the duration and intensity of efforts based on heart rate. Target Load suggests a daily range for Cardio Load based on fitness level, recent activity, and body recovery. The features are available on various Fitbit smartwatches and trackers, as well as Pixel Watch 1, 2, and 3.
