Try This 45-Minute Treadmill Workout Video to Build Your Endurance

Who says running on a treadmill has to be boring? If cardio machines feel like detention to you (or if you're forced to do your long run on the treadmill), but you still want to get your heart pumping, then this 45-minute treadmill workout video will be your savior.

The endurance-boosting workout, recorded live at MyStryde running studio in Boston, will have you sweating puddles just watching it. It starts with a warm-up, where you'll power walk or jog (if you're already feeling pumped) at a 2 percent incline. From there, it's divided into three parts: a gentle incline, a steeper hill, and (of course) sprints. You can play this video as you do the workout-don't worry, the music and the trainer are equally motivating-or follow along with the interval guide below if you want to jam to your own playlist. (Just be careful not to make these treadmill workout mistakes.)
