Google expands automatic workout detection across Pixel Watches and Fitbit wearables

Google is rolling out version 5.11 of the Google Health app on Android and iOS, dramatically expanding its automatic workout detection capabilities. Supported wearables—including the Fitbit Air, Pixel Watch 3, 4, and 5, as well as the upcoming Fitbit Edge scheduled to launch next week—can now automatically identify and log more than 100 exercise types, up from just 10 previously.

The enhanced tracking system covers exercises such as swimming, strength training, golf, racket sports, and cardio machines. The feature works by combining contextual reasoning with location data, workout routines, historical activity, and manual corrections. Sessions that sustain an elevated heart rate and hit duration thresholds are logged automatically, with summary notifications arriving within 30 minutes. Google says the upgrade delivers nearly twice the detection accuracy while cutting missed workouts by more than half as it learns from user confirmations. [3][4]
