A method, comprising: at an electronic device (100, 300, 500, 600) with a display, a touch-sensitive surface, and a physical activity tracking sensor: displaying a scrollable list of affordances associated with physical activities; while displaying the scrollable list of affordances associated with physical activities: displaying a first change workout metrics affordance corresponding to a first affordance of the scrollable list of affordances, wherein the first affordance of the scrollable list of affordances includes the first change workout metrics affordance; and receiving a first user input; in accordance with a determination that the first user input is detected at the first affordance in the scrollable list of affordances, launching a physical activity tracking function associated with the selected first affordance; in accordance with a determination that first the user input is detected at the first change workout metrics affordance corresponding to the first affordance, displaying a first user interface configured to change a workout metric; wherein the first user interface includes a plurality of metric affordances associated with the physical activity associated with the first affordance; while displaying the first user interface configured to change a workout metric, detecting a second user input at a specific metric affordance of the plurality of metric affordances in the first user interface, and displaying a second user interface configured to change a specific workout metric corresponding to the specific metric affordance; while displaying the second user interface configured to change a specific workout metric, detecting a third user input; and in accordance with a determination that the third user input is detected at a start affordance in the second user interface, launching the physical activity tracking function associated with the selected start affordance. displaying a scrollable list of affordances associated with physical activities; while displaying the scrollable list of affordances associated with physical activities: displaying a first change workout metrics affordance corresponding to a first affordance of the scrollable list of affordances, wherein the first affordance of the scrollable list of affordances includes the first change workout metrics affordance; and receiving a first user input; in accordance with a determination that the first user input is detected at the first affordance in the scrollable list of affordances, launching a physical activity tracking function associated with the selected first affordance; in accordance with a determination that first the user input is detected at the first change workout metrics affordance corresponding to the first affordance, displaying a first user interface configured to change a workout metric; wherein the first user interface includes a plurality of metric affordances associated with the physical activity associated with the first affordance; while displaying the first user interface configured to change a workout metric, detecting a second user input at a specific metric affordance of the plurality of metric affordances in the first user interface, and displaying a second user interface configured to change a specific workout metric corresponding to the specific metric affordance; while displaying the second user interface configured to change a specific workout metric, detecting a third user input; and in accordance with a determination that the third user input is detected at a start affordance in the second user interface, launching the physical activity tracking function associated with the selected start affordance. displaying a first change workout metrics affordance corresponding to a first affordance of the scrollable list of affordances, wherein the first affordance of the scrollable list of affordances includes the first change workout metrics affordance; and receiving a first user input; in accordance with a determination that the first user input is detected at the first affordance in the scrollable list of affordances, launching a physical activity tracking function associated with the selected first affordance; in accordance with a determination that first the user input is detected at the first change workout metrics affordance corresponding to the first affordance, displaying a first user interface configured to change a workout metric; wherein the first user interface includes a plurality of metric affordances associated with the physical activity associated with the first affordance; while displaying the first user interface configured to change a workout metric, detecting a second user input at a specific metric affordance of the plurality of metric affordances in the first user interface, and displaying a second user interface configured to change a specific workout metric corresponding to the specific metric affordance; while displaying the second user interface configured to change a specific workout metric, detecting a third user input; and in accordance with a determination that the third user input is detected at a start affordance in the second user interface, launching the physical activity tracking function associated with the selected start affordance.
