i started "INSANITY" today and its a 2month workout dvd, it consists of alot of cardio!!! i also own P90x and will start that right after i finish Insanity... i figured id drop weight with insanity then build muscle with P90x... i live on the 3rd floor of my apt but lucky for me my parents live less then a mile away so i wake up and drive to their house and workout.. longest Insanity video is prob 1 hour. let me know if yall have any questions about it
