Has anyone tried this video yet? It seems like a little bit of a joke, but sometimes these things turn out to be really effective. I'm wondering if anyone here has any personal experience with it? They have silly gimmicks, for example, at the end of the 90 days you receive a t-shirt. They use this as an advertising segment in the show, saying stuff like "YOU GOTTA EARN THE SHIRT!", etc. Here's the website's description. "The secret to these mind-blowing INSANITY workout results: MAX Interval Training. Shaun T took traditional interval training and flipped it on its head—you perform long bursts of maximum-intensity exercises with short periods of rest. Each INSANITY workout keeps you constantly challenged as you alternate between aerobic and anaerobic intervals performed at your MAX. The result: burn up to 1,000 calories in an hour and get the most insane body in 60 days." What do you think? Tried it? Liked it? Hated it? Havn't tried it? What do you think?
