If you are ready to dig deeper than you ever have in a workout - ready to push yourself
harder than you have ever had to push before in a workout - if you want to see just how far you can push yourself both mentally and physically - if you want to get the body of your dreams in just 60 day and you are willing to work hard for it, then Beachbody's Insanity is for you. Insanity is a 60 day cardio based total body training program. Insanity brings total body training to a whole new level of extreme. At the end of 60 days you will have better endurance, slimmer legs, lower resting heart rate, faster cardiac response, and better body definition.
INSANITY does this with Max Interval Training. Normal interval training allows you to push through the "stress adaptation response", this is what happens when your body becomes accustomed to one level of training. Interval training includes short bursts of moderate intensity training in between lower intensity training.
Max Interval Training turns interval training on its head. With Max Interval Training you have long periods of maximum intensity training with short periods of lower intensity training. This higher intensity training forces your body to use fast muscle twitching when your heart rate is raised to 80% or more of its capacity. This higher intensity will result in faster increases in fitness and more efficient burning of carbs and fat.
Insanity not only challenges your body but also challenges your mind. You will pushed harder and challenged to dig deeper to reach your goals. Insanity will push you physically and mentally to the edge of your endurance.
