What is High Intensity Interval Training (HIIT)?
High Intensity Interval Training, often represented by the acronym HIIT, is really a big deal. HIIT training is the ideal and most effective replacement for underachieving endurance cardio. As a matter of fact, in studies HIIT is 9x more effective at burning fat than endurance cardio. More often than not, I have talked about HIIT workouts made up only of interval sprints. Today I would like to discuss HIIT training with resistance machines, but not to be confused with High Intensity Resistance Training, or HIRT, which I will write about shortly.
