Treadmill run/walk
Each level adds running time. Repeat a level until it feels comfortable, then move up.
Same effort as your current level, different shape. Good for the days the plan feels stale.
Keep this screen open. You'll hear a beep countdown and a voice cue before every change, so you can look away and watch something else.

Every workout uses these. Pick a walk that is brisk and a run you could hold while still able to say a short sentence.
