Apparently there is a new Insanity workout coming from Shaun T. It is supposedly coming out early 2011 and according to Shaun T himself:
I just finished a program called ‘Asylum’ because I had to take it a step forward. With ‘Insanity,’ it is based off max integral training and your best. I took all of that and made ‘Asylum’ really sports-specific. There’s a workout called Game Day, where you are doing all these different sports. You’re using your agility and speed. It’s really for the person who wants the athletic body and mentality.
Sounds like a step away from the aerobics dropouts and more towards the conditioned athlete. Personally, I can’t wait!
