HIIT is killer for rapid gains. The problem is most people think they are doing it right, but they are not. It’s difficult and goes against your self preservation to consistently push yourself to such uncomfortable levels, which is required in this type of training.
True HIIT means fearing you are actually dying and at least going to vomit.
