The Insanity Workout was created by former track star and now celebrity trainer Shaun T. Billed as the most extreme workout on DVD, it's essentially a variation on High Intensity Interval Training, which Shaun T has modified according to the principles of his Max Interval Training.
Shaun T set out to create a program that would push people to their very limits and beyond, and in doing so allow them to burn so many calories and develop the results that normally take six months or more in just 60 days. By combining plyometrics, traditional cardio, calisthenics, sports drill and core work in incredibly intense and efficient packages, Shaun delivers the most incredible workout right to your door.
So if you are ready to go insane, and if you're ready to develop the most extreme results in the shortest amount of time,Insanity is for you!
The is a total lifestyle change. Once you sign on, there's no going back. So what do you get in the box to help you make this transition?
