- Start the treadmill and walk slowly for 2 minutes.
- Increase the treadmill speed to 8.5 mph and the incline to 12% while standing on the sides of the treadmill.
- As soon as it’s up to speed, sprint for 20 seconds.
- At the end of the 20 seconds, jump back on the side of the belt and rest for 10 seconds. (Grab the handrails. Trust me.)
- Repeat 10 times.
- Drop the speed and the incline and walk slowly for another 2 minutes.
