Are there such things are interval dvds? I don't mean dvds you watch while doing interval training, but rather dvds that mimmick interval training but not using a machine? I've been looking around and don't see much. The aerobic or cardio ones just don't quite 'do it' for me. They either don't get my HR up enough or are too 'dancey' or something.
