12-5-30: The Workout Method to Lose Weight and Tone Up

What is the 12 5 30 method?

The 12-5-30 method is a cardio workout you do on a treadmill.
Its name comes from three fixed settings:

• 12 → treadmill incline at 12%

• 5 → walking speed at 5 km/h

• 30 → workout duration: 30 minutes

The principle is simple:

👉 walk at a moderate pace, but on a steep incline, without changing your speed or incline throughout the entire session.
