With the holidays approaching and Jack Frost nipping at your runner toes, this is the greatest time of the year to find the most efficient way to toast fat and stay strong in your running. The treadmill is not only your answer, but it’s also likely to become one of your favorite new ways to mix up your running. With the right plan, and a well-designed workout, you will get the runner’s high in a whole new way. Here is a run from The Ultimate Treadmill Workout to get you started.

“Evil Twin”

Segment 1

Here you’ll do twin intervals, except one is the nice twin and one is the evil twin. Estimate a goal for your fastest 30-second sprint you think you can do on a treadmill (known as your personal best or “PB”) and subtract -2.0 mph to find your starting speed (you will build to get to your PB). The example speed is only an example, so be sure to fill in your speed goals in the column and get ready to work!

INTERVAL SPEED
Your Speed
INCLINE RECOVERY (all 0%)
60 seconds (-2.0 from PB) Ex: 6.0 mph 0% 1 minute moderate recovery
60 seconds Same Speed Ex: 6.0 mph 4% 1 minute moderate recovery
45 seconds +0.5 mph
Ex: 6.5 mph
0% 1 minute moderate recovery
45 seconds Same Speed Ex: 6.5 mph 4% 1 minute moderate recovery
30 seconds +0.5 mph
Ex: 7.0 mph
0% 1 minute moderate recovery
30 seconds Same Speed Ex: 7.0 mph 4% 2 minute complete recovery

Segment 2

Now you’ll repeat the concept with a slightly smaller incline. The catch here is that you must start this segment at the speed you ended the previous! Be brave and confident!

INTERVAL SPEED
Your Speed
INCLINE RECOVERY (all 0%)
60 seconds Last Speed Ex: 7.0 mph 0% 1 minute moderate recovery
60 seconds Same Speed Ex: 7.0 mph 3% 1 minute moderate recovery
45 seconds +0.5 mph
Ex: 7.5 mph
0% 1 minute moderate recovery
45 seconds Same Speed Ex: 7.5 mph 3% 1 minute moderate recovery
30 seconds +0.5 mph
Ex: 8.0 mph
0% 1 minute moderate recovery
30 seconds Same Speed Ex: 8.0 mph 3% 2-3 minute Cool Down
