The main appeal of HIIT for many people is that it's an incredibly versatile format that allows for condensed training times. The acronym is as catchy as any in the workout world, and the protocol is as popular as it is effective-if you've taken any group fitness classes in the recent past, there's a good chance you were doing a HIIT routine (or at least, the coach leading the class thought you were doing a HIIT routine. You might know it better by the shorthand term used by fitness coaches and group training acolytes everywhere: HIIT.
