A system and method to obtain activity data for an activity of a user, the activity data corresponding to multiple parameters. A set of threshold criteria that corresponds to a multi-parameter activity zone is retrieved, where the set of threshold criteria includes an effort threshold criteria related to a heart rate of the user. An effort of the user is determined based on the activity data. A resistance experienced by the user is determined, where the resistance includes a measure representing at least one of stride rate, step rate, steps, or cadence. A posture of the user is determined. Based on the set of threshold criteria corresponding to the multi-parameter activity zone, an instance of the activity is classified as an activity type based on the resistance experienced by the user, the effort of the user, and the posture of the user. |
