I like to pump up the incline when I am on the treadmill, but I also like to run at a faster speed. So since it's too hard for me to always do both at once, I combine the speed and incline with a fun workout that has you changing things up every two and a half minutes. For the workout, just
|Time||Incline (%)||Speed (MPH)|
Fit's Tip: If this is too hard, go a bit slower until you build up your endurance. Once you get bored, do the program in reverse to get an entirely different cardio workout.
