During a workout, there are two screens that you can view to get information on your workout.
The Workout Heart Rate Screen can be accessed by pressing the Lower button once. This screen shows your BPM(beats per minute) if you have the optional heart rate monitor connected to the watch. It will also show you the the total time you have been working out.
The Workout Details screen can be accessed by pressing the Upper button from the Date/Time Screen. You can view your total distance, calories burned, pace, and duration of your workout.
