How to Do the 12-3-30 Treadmill Workout

The 12-3-30 routine only requires a treadmill and 30 minutes of time. Here are the basics of how to perform this workout:

Set the Treadmill Speed

Set the speed to 3.0 mph, which is a moderate power walking pace. This will remain constant throughout the full 30 minutes.

Start at 0% Incline

Begin walking with the treadmill incline set to 0% for the first 3 minutes. This allows your body to warm up.

Increase Incline Every 3 Minutes

Increase the incline by 2% every 3 minutes until you reach 12%. So at minute markers 3, 6, 9, 12, 15, 18, 21, 24 and 27, bump up the incline 2% each time. The last 3 minutes will be at 12% incline.

Walk for 30 Minutes Straight

Continue walking at 3.0 mph for the full 30 minute duration as the incline increases. The wide range of inclines challenges your muscles in different ways.

Cool Down

Finish by walking at 0% incline again for 3 to 5 minutes to cool down. Stretch your legs as well when you're done.
