HIIT on Treadmill

if you are not switching up your workouts regularly you are not going to progress.

Look at the metrics and compare them, if they are not improving you need to change it up

In addition to improving speed and endurance, play with the incline function or run outside where you can go up and down hills and run on different surfaces. That helps improve your balance and works different muscles, to help avoid injury.
