Your workout keeps running when your phone is locked, so countdown beeps carry on and the lock screen stays current. The lock screen shows each phase in its color and, with a heart rate sensor, your heart rate with Push, In range or Ease off. A new target bar shows where your heart rate sits in your range during every work interval. Workout overviews now explain their colors, and indoor workouts no longer show an empty pace.
