Definition
High-Intensity Interval Training, a workout method that alternates between going as hard as humanly possible and desperately gasping for air. It promises maximum results in minimum time, which is fitness-speak for maximum suffering in minimum time.
Example Usage
"My HIIT class was only twenty minutes long but I aged approximately fifteen years during it, making it the worst trade deal in the history of time management."
