Insanity is a 2 month at home work out DVD program. I have always looked at Insanity's infomercials and wanted to obtain the best body I could have. So I decided to purchase it. Ever since the my body has got better and I have so much more energy. It is the hardest workout ever put on DVD. But I cant stop now I started I think it's insane if you don't try it. I'm on my last week and I'm so excited to finish so I can have my beach body.
