beachbody insanity i thought was a great little hiit video to download. good for free shit to do at home. def dropped some weight last time i did it, and with the dude on the tv yelling at u it helps too
This is more of an aerobic workout as well from what I know of it. You cant keep up true intensity for 40+ minutes. To really get EPOC effects you want to be done in 8-12 minutes and feel like your gonna die.
