Did you just start back this New Year with your exercising and feel like some of the cardio plans out there (even the others on our site) may be a little too hard? Knock this one out of the park with our Beginner Cardio Treadmill Interval Workout. It's not HIIT, but we suggest you give yourself just a little more time before you start introducing insane HIIT routines into your workouts. Go on, you have this one in the bag!
Note: This workout will have you running. If you haven't run in a while, we do suggest that you ease into this workout with slower MPH speeds.
