HIIT is an acronym for High-Intensity Interval Training. It is a workout style that people love and combines short intense bursts of activity with short rest periods. This approach is the mainstay of both fat burning and turnover, and not to forget it kills two birds with one stone—strength is also developed rapidly.

This specific challenge contains 12 exercises. You have the options to do 10 to 15 reps or go by time with 30 to 45 seconds per move. Allow yourself 30 seconds to 1 minute break after each move, or take as long as you need. The tasks are to successfully accomplish 2 to 3 rounds.
