Do you need to be insane to do the Insanity Workout? It appears to work for many people and there are even reviews from people aged from 17 to 40 and above, who love it and are getting results. Both men and women can do it and no special equipment is needed.

A calendar shows you what exercises you should be doing when, and keeps you motivated by tracking your progress and helping you set goals. The exercises are done at home watching the workout DVDs and only take from 30 minutes to an hour each day.

Even if you are not fit, you can follow this program, according to reviews, as you can work at your own pace until you feel ready to keep up with the DVD. It is not dance-based so those who like to exercise to music will probably not choose it. However, if you want hard, intensive workouts that make you sweat then this is the program for you!
