Quick refresher and Tabata; Tabata workouts are a HIIT style workout. You go hard for, and I mean all out hard, for 20 seconds then you get to rest for 10 seconds. Repeat this cycle for 8 rounds, 4 minutes total. Take a 1 minute break before starting the next movement. You need to push hard enough in those 20 seconds that you WANT your 10 second breather.
Work hard! Have fun! Earn that sweaty smile!
