Insanity is a total body workout that requires no gym or equipment. … The program is based on a fitness method called “max interval training.” In traditional interval training, you exercise at a very intense pace for a short period of time, and then rest for longer periods in between.
The Insanity workout is an advanced exercise program. It involves body weight exercises and high-intensity interval training. Insanity workouts are performed 20 to 60 minutes at a time, 6 days a week for 60 days.
If you’re interested in trying the Insanity program, talk to your doctor. They can help you determine if this intensity of fitness is safe for you.
