- Lower-body strength and power
The Treadmill Challenge is unlike anything you've ever done on a treadmill, and if you can complete it on your first try, you're in pretty darn good shape.
Rather than running with the treadmill on, set the the treadmill to a steep incline and turn the belt off. Grasp the front handles and rapidly drive your legs to propel the belt like you're an Olympic bobsledder. You become the motor.
This turns the treadmill into a lower-body strength and power tool, offering the same benefits as sled-pushing exercises. Your hips, glutes, quads and calves fire to push the belt, similar to how you accelerate into a sprint.
Each interval calls for a sprint followed by a brief period of rest. You will sprint at near your max speed to increase your strength and power, while also keeping your heart rate elevated. In only 10 minutes, you will improve your anaerobic endurance, which allows you to sprint at full speed for a longer duration.
