Shaun T Insanity Workout (available @ http://www.extremefitnessresults.com/...)

INSANITY Workout (aka Insanity Fitness) is a 60-day cardio-based total-body conditioning program thats perhaps the most intense workout ever put on DVD. Fitness expert Shaun T drew on his collegiate track and field training plus his subsequent years of experience as an elite trainer to create a program that takes total-body conditioning to an extreme level. Just as P90X is the height of resistance training, so INSANITY is the pinnacle of cardio training.


Why Does the Insanity Workout Work? Secret: Interval Training

Interval training allows you to beat the stress adaptation response, which is what happens when your body gets used to exercising at one level of exertion and stops improving. An interval workout includes a set where you perform at your maximum, followed by one of lower intensity, with the cycle repeated to achieve a cumulative effect. SHAUN T INSANITY uses MAX Interval Training which replaces your moderate intensity exercise with maximum-intensity exercise, and your short intervals of intensity with short periods of rest. Adding high-intensity exercise, during which your heart rate is raised to 80 percent or more of its maximum capacity, forces your body to use fast-twitch muscle fibers not normally engaged in cardio exercise. These fast-twitch fibers continue burning extra fuel even during lower-intensity exercise. INSANITYs high-intensity activity is likely to have you working out at over 85% of your maximum, instead of the lower rate recommended in other programs. As a result, youll experience faster increases in fitness and more efficient burning of carbohydrates and fat—as much as 1,000 calories per hour.
