Whether you are looking to enhance your running performance or you are just looking for an intense workout that will blast fat and boost your metabolism, interval sprinting workouts are an amazingly efficient way to kick your own butt on the treadmill with minimal time spent at the gym.

Increasing running speed or endurance doesn’t require hours on the treadmill. It doesn’t even require that you push yourself to the brink of your own physical condition limits through the entire routine. Sprinting intervals are a fantastic and efficient tool for runners that will provide the most gains in the least amount of time.

Treadmill Interval Workout:

In order to do this program, you should already be comfortable on the treadmill and with cardio training in general. It doesn’t take very long to build up to this kind of plan; either the Treadmill Incline Routine or the Treadmill Workout using Walking/Running Intervals can be a great place to start building a base of aerobic fitness.

To push your aerobic threshold even further maintain a higher recovery speed during your jog or do the entire interval with a small amount of incline. Adding a 1-5% incline drastically increases the required cardiovascular endurance.
