Interval Training

Q: Running at a constant pace is for endurance and varying the intensity levels (called interval training) is good for strength and speed. it is a good way to improve your time if you race or if you are having trouble getting over a platue. Keep up the good work.

A:  I was on a workout program for a few weeks that stressed doing your cardio workouts using a mix of high intensity and low intensity periods. (example: 2 min of running, 2 min of walking, 2 min of high intensity running, etc.) What is the benefit of varying the intensity as opposed to just running at the same pace for 30 minutes?
